 1.1 Summary
 ===========
 
 Org Mode is an authoring tool and a TODO lists manager for GNU Emacs.
 It relies on a lightweight plain-text markup language used in files with
 the ‘.org’ extension.
 
    Authoring Org files is best supported by Emacs, but you can view,
 understand, and change them with any text editor.
 
    As an authoring tool, Org helps you write structured documents and
 provides exporting facilities.  Org files can also be used for literate
 programming and reproducible research.  As a TODO lists manager, Org
 helps you organize your tasks in a flexible way, from daily needs to
 detailed project-planning, allowing logging, multiple views on your
 tasks, exporting your agendas, etc.
 
    Org mode is implemented on top of Outline mode, which makes it
 possible to keep the content of large files well structured.  Visibility
 cycling and structure editing help to work with the tree.  Tables are
 easily created with a built-in table editor.  Plain text URL-like links
 connect to websites, emails, Usenet messages, BBDB entries, and any
 files related to the projects.
 
    Org develops organizational tasks around notes files that contain
 lists or information about projects as plain text.  Project planning and
 task management make use of metadata which is part of an outline node.
 Based on this data, specific entries can be extracted in queries and
 create dynamic _agenda views_ that also integrate the Emacs calendar and
 diary.  Org can be used to implement many different project planning
 schemes, such as David Allen’s GTD system.
 
    Org files can serve as a single source authoring system with export
 to many different formats such as HTML, LaTeX, Open Document, and
 Markdown.  New export backends can be derived from existing ones, or
 defined from scratch.
 
    Org files can include source code blocks, which makes Org uniquely
 suited for authoring technical documents with code examples.  Org source
 code blocks are fully functional; they can be evaluated in place and
 their results can be captured in the file.  This makes it possible to
 create a single file reproducible research compendium.
 
    Org keeps simple things simple.  When first fired up, it should feel
 like a straightforward, easy to use outliner.  Complexity is not
 imposed, but a large amount of functionality is available when needed.
 Org is a toolbox.  Many users actually run only a—very personal—fraction
 of Org’s capabilities, and know that there is more whenever they need
 it.
 
    All of this is achieved with strictly plain text files, the most
 portable and future-proof file format.  Org runs in Emacs.  Emacs is one
 of the most widely ported programs, so that Org mode is available on
 every major platform.
 
    There is a website for Org which provides links to the newest version
 of Org, as well as additional information, frequently asked questions
 (FAQ), links to tutorials, etc.  This page is located at
 <https://orgmode.org>.
 
    An earlier version (7.3) of this manual was available as a paperback
 book from the Network Theory Ltd.  publishing company, closed in 2009.
 
 
 File: org.info,  Node: Installation,  Next: Activation,  Prev: Summary,  Up: Introduction
 
 1.2 Installation
 ================
 
 Org is included in distributions of GNU Emacs, you probably do not need
 to install it.  Most users will simply activate Org and begin exploring
 its features.
 
    If, for one reason or another, you want to install Org on top of this
 pre-packaged version, you can use the Emacs package system or clone
 Org’s git repository.  We *strongly recommend* sticking to a single
 installation method.
 
    When installing Org on top of the pre-packaged version, please note
 that Org stable versions are meant to be fully compatible with the last
 three stable versions of Emacs but not with older Emacsen.
 
    Some Org components also depend on third-party packages available
 through package archives.  Org is only guaranteed to be compatible with
 the latest stable versions of these third-party packages.
 
 Using Emacs packaging system
 ----------------------------
 
 Recent Emacs distributions include a packaging system which lets you
 install Elisp libraries.  You can install Org from the “package menu”,
 with ‘M-x list-packages’.  See *note Package Menu: (emacs)Package Menu.
 
      Important: You need to do this in a session where no ‘.org’ file
      has been visited, i.e., where no Org built-in function have been
      loaded.  Otherwise autoload Org functions will mess up the
      installation.
 
    To avoid interference with built-in Org mode, you can use command
 line:
 
      emacs -Q -batch -eval "(progn (require 'package) (package-initialize) (package-refresh-contents) (package-upgrade 'org))"
 
    This approach has the advantage of isolating the upgrade process from
 a running Emacs session, ensuring that version conflicts can not arise.
 
 Using Org’s git repository
 --------------------------
 
 You can clone Org’s repository and install Org like this:
 
      $ cd ~/src/
      $ git clone https://git.savannah.gnu.org/git/emacs/org-mode.git
      $ cd org-mode/
      $ make autoloads
 
    Note that in this case, ‘make autoloads’ is mandatory: it defines
 Org’s version in ‘org-version.el’ and Org’s autoloads in
 ‘org-loaddefs.el’.
 
    Make sure you set the load path correctly in your Emacs init file:
 
      (add-to-list 'load-path "~/src/org-mode/lisp")
 
    You can also compile with ‘make’, generate the documentation with
 ‘make doc’, create a local configuration with ‘make config’ and install
 Org with ‘make install’.  Please run ‘make help’ to get the list of
 compilation/installation options.
 
    For more detailed explanations on Org’s build system, please check
 the Org Build System page on Worg
 (https://orgmode.org/worg/dev/org-build-system.html).
 
 Installing Org’s contributed packages
 -------------------------------------
 
 Org’s repository used to contain ‘contrib/’ directory for add-ons
 contributed by others.  As of Org 9.5, the directory has been moved to
 the dedicated org-contrib repository
 (https://git.sr.ht/~bzg/org-contrib), which you can install separately
 as a package (https://elpa.nongnu.org/nongnu/org-contrib.html) from
 NonGNU ELPA.
 
    There are enough valuable packages maintained outside of the Org
 repository.  Worg has a list of org-contrib and external packages
 (https://orgmode.org/worg/org-contrib/index.html), certainly it is not
 exhaustive.

 1.3 Activation
 ==============
 
 Org mode buffers need Font Lock to be turned on: this is the default in
 Emacs(1).
 
    There are compatibility issues between Org mode and some other Elisp
 packages (see *note Conflicts::).  Please take the time to check the
 list.
 
    For a better experience, the three Org commands ‘org-store-link’,
 ‘org-capture’ and ‘org-agenda’ ought to be accessible anywhere in Emacs,
 not just in Org buffers.  To that effect, you need to bind them to
 globally available keys, like the ones reserved for users (see *note
 (elisp)Key Binding Conventions::).  Here are suggested bindings, please
 modify the keys to your own liking in your *note personal init file:
 (emacs)Init File.
 
      (global-set-key (kbd "C-c l") #'org-store-link)
      (global-set-key (kbd "C-c a") #'org-agenda)
      (global-set-key (kbd "C-c c") #'org-capture)
 
    Files with the ‘.org’ extension use Org mode by default.  To turn on
 Org mode in a file that does not have the extension ‘.org’, make the
 first line of a file look like this:
 
      MY PROJECTS    -*- mode: org; -*-
 
 which selects Org mode for this buffer no matter what the file’s name
 is.  See also the variable ‘org-insert-mode-line-in-empty-file’.
 
    Many commands in Org work on the region if the region is _active_.
 To make use of this, you need to have Transient Mark mode turned on,
 which is the default.  If you do not like it, you can create an active
 region by using the mouse to select a region, or pressing ‘C-<SPC>’
 twice before moving point.
 
    ---------- Footnotes ----------
 
    (1) If you do not use Font Lock globally turn it on in Org buffer
 with ‘(add-hook 'org-mode-hook #'turn-on-font-lock)’.

 1.4 Feedback
 ============
 
 If you find problems with Org, or if you have questions, remarks, or
 ideas about it, please send an email to the Org mailing list
 <mailto:emacs-orgmode@gnu.org>.  You can subscribe to the list from this
 web page (https://lists.gnu.org/mailman/listinfo/emacs-orgmode).  If you
 are not a member of the mailing list, your mail will be passed to the
 list after a moderator has approved it(1).  We ask you to read and
 respect the GNU Kind Communications Guidelines
 (https://www.gnu.org/philosophy/kind-communication.html) when sending
 messages on this mailing list.  Please allow up to one month for the
 response and followup if no response is received on the bug report.
 
    For bug reports, please first try to reproduce the bug with the
 latest version of Org available—if you are running an outdated version,
 it is quite possible that the bug has been fixed already.  If the bug
 persists, prepare a report and provide as much information as possible,
 including the version information of Emacs (‘M-x emacs-version’) and Org
 (‘M-x org-version’), as well as the Org related setup in the Emacs init
 file.  The easiest way to do this is to use the command
 
      M-x org-submit-bug-report <RET>
 
 which puts all this information into an Emacs mail buffer so that you
 only need to add your description.  If you are not sending the Email
 from within Emacs, please copy and paste the content into your Email
 program.
 
    Sometimes you might face a problem due to an error in your Emacs or
 Org mode setup.  Before reporting a bug, it is very helpful to start
 Emacs with minimal customizations and reproduce the problem.  Doing so
 often helps you determine if the problem is with your customization or
 with Org mode itself.  You can start a typical minimal session with a
 command like the example below.
 
      $ emacs -Q -l /path/to/minimal-org.el
 
    However if you are using Org mode as distributed with Emacs, a
 minimal setup is not necessary.  In that case it is sufficient to start
 Emacs as ‘emacs -Q’.  The ‘minimal-org.el’ setup file can have contents
 as shown below.
 
      ;;; Minimal setup to load latest `org-mode'.
 
      ;; Activate debugging.
      (setq debug-on-error t
            debug-on-signal nil
            debug-on-quit nil)
 
      ;; Add latest Org mode to load path.
      (add-to-list 'load-path (expand-file-name "/path/to/org-mode/lisp"))
 
    If you are using Org mode version from Git repository, you can start
 minimal session using make.
 
      # Bare Emacs
      make repro
      # or pass extra arguments
      make repro REPRO_ARGS="-l /path/to/minimal/config.el /tmp/bug.org"
 
    If an error occurs, a “backtrace” can be very useful—see below on how
 to create one.  Often a small example file helps, along with clear
 information about:
 
   1. What exactly did you do?
   2. What did you expect to happen?
   3. What happened instead?
 
    If you experience degraded performance, you can record a “profile”
 and share it on the Org mailing list.  See below for the instructions
 how to record a useful profile.
 
    Thank you for helping to improve this program.
 
 How to create a useful backtrace
 --------------------------------
 
 If working with Org produces an error with a message you do not
 understand, you may have hit a bug.  The best way to report this is by
 providing, in addition to what was mentioned above, a backtrace.  This
 is information from the built-in debugger about where and how the error
 occurred.  Here is how to produce a useful backtrace:
 
   1. Reload uncompiled versions of all Org mode Lisp files.  The
      backtrace contains much more information if it is produced with
      uncompiled code.  To do this, use
 
           C-u M-x org-reload <RET>
 
      or, from the menu: Org → Refresh/Reload → Reload Org uncompiled.
 
   2. Then, activate the debugger:
 
           M-x toggle-debug-on-error <RET>
 
      or, from the menu: Options → Enter Debugger on Error.
 
   3. Do whatever you have to do to hit the error.  Do not forget to
      document the steps you take.
 
   4. When you hit the error, a ‘*Backtrace*’ buffer appears on the
      screen.  Save this buffer to a file—for example using ‘C-x C-w’—and
      attach it to your bug report.
 
 How to profile Org performance
 ------------------------------
 
 Sometimes, Org is becoming slow for no apparent reason.  Such slowdown
 is often caused by interaction between third-party packages and Org
 mode.  However, identifying the root cause is not always
 straightforward.
 
    Emacs is able to record performance statistics, which can then be
 used to find out which functions are taking most of the time to execute.
 To record the statistics, one can use so-called profiler.  To use the
 Emacs profiler, we recommend the following steps:
 
   1. Make sure that no profiler is currently active:
 
           M-x profiler-stop <RET>
 
   2. Start a new CPU profiler session:
 
           M-x profiler-start <RET> cpu <RET>
 
   3. Use Emacs as usual, performing the actions that are deemed slow.
 
   4. Display and examine the recorded performance statistics:
 
           M-x profiler-report <RET>
 
      This command will display a summary of the commands and functions
      that have been executed between ‘profiler-start’ and
      ‘profiler-report’ invocations, with command taking most of the time
      displayed on top.
 
      ‘<TAB>’ key can be used to fold and unfold lines in the profiler
      buffer.  The child items revealed upon unfolding are the functions
      and commands called by the unfolded parent.
 
      The root causes are often buried deep inside sub-children items in
      the profiler.  You can press ‘B’
      (‘profiler-report-render-reversed-calltree’) to quickly reveal the
      actual function/command that takes most of the time to run.
 
      Pressing ‘C’ ‘profiler-report-render-calltree’ will recover the
      original view.
 
   5. If you need further help, you can share the statistics data.
 
      Just save the data by issuing
 
           M-x profiler-report-write-profile <RET>
           /path/to/profile-file-to-be-saved <RET>
 
      Then, you can attached the saved file to your email to the Org
      mailing list, alongside with details about what you did to trigger
      the slowdown.
 
      Note that the saved statistics will only contain the function names
      and how long their execution takes.  No private data will be
      recorded.

 1.5 Typesetting Conventions Used in this Manual
 ===============================================
 
 TODO keywords, tags, properties, etc.
 -------------------------------------
 
 Org uses various syntactical elements: TODO keywords, tags, property
 names, keywords, blocks, etc.  In this manual we use the following
 conventions:
 
 ‘TODO’
 ‘WAITING’
      TODO keywords are written with all capitals, even if they are
      user-defined.
 
 ‘boss’
 ‘ARCHIVE’
      Tags are case-sensitive.  User-defined tags are usually written in
      lowercase; built-in tags with special meaning are written as they
      should appear in the document, usually with all capitals.
 
 ‘Release’
 ‘PRIORITY’
      User-defined properties are capitalized; built-in properties with
      special meaning are written with all capitals.
 
 ‘TITLE’
 ‘BEGIN’ ... ‘END’
      Keywords and blocks are written in uppercase to enhance their
      readability, but you can use lowercase in your Org files.
 
 Key bindings and commands
 -------------------------
 
 The manual lists both the keys and the corresponding commands for
 accessing a functionality.  Org mode often uses the same key for
 different functions, depending on context.  The command that is bound to
 such keys has a generic name, like ‘org-metaright’.  In the manual we
 will, wherever possible, give the function that is internally called by
 the generic command.  For example, in the chapter on document structure,
 ‘M-<RIGHT>’ will be listed to call ‘org-do-demote’, while in the chapter
 on tables, it will be listed to call ‘org-table-move-column-right’.
 
 
 File: org.info,  Node: Document Structure,  Next: Tables,  Prev: Introduction,  Up: Top
 
 2 Document Structure
 ********************
 
 Org is an outliner.  Outlines allow a document to be organized in a
 hierarchical structure, which, least for me, is the best representation
 of notes and thoughts.  An overview of this structure is achieved by
 folding, i.e., hiding large parts of the document to show only the
 general document structure and the parts currently being worked on.  Org
 greatly simplifies the use of outlines by compressing the entire show
 and hide functionalities into a single command, ‘org-cycle’, which is
 bound to the ‘<TAB>’ key.

 File: org.info,  Node: Headlines,  Next: Visibility Cycling,  Up: Document Structure
 
 2.1 Headlines
 =============
 
 Headlines define the structure of an outline tree.  Org headlines start
 on the left margin(1) with one or more stars followed by a space.  For
 example:
 
      * Top level headline
      ** Second level
      *** Third level
          some text
      *** Third level
          more text
      * Another top level headline
 
    The name defined in ‘org-footnote-section’ is reserved.  Do not use
 it as a title for your own headings.
 
    Some people find the many stars too noisy and would prefer an outline
 that has whitespace followed by a single star as headline starters.
 This can be achieved using an Org Indent minor mode.  See *note Clean
 View:: for more information.
 
    Headlines are not numbered.  However, you may want to dynamically
 number some, or all, of them.  See *note Dynamic Headline Numbering::.
 
    An empty line after the end of a subtree is considered part of it and
 is hidden when the subtree is folded.  However, if you leave at least
 two empty lines, one empty line remains visible after folding the
 subtree, in order to structure the collapsed view.  See the variable
 ‘org-cycle-separator-lines’ to modify this behavior.
 
    ---------- Footnotes ----------
 
    (1) See the variables ‘org-special-ctrl-a/e’, ‘org-special-ctrl-k’,
 and ‘org-ctrl-k-protect-subtree’ to configure special behavior of ‘C-a’,
 ‘C-e’, and ‘C-k’ in headlines.  Note also that clocking only works with
 headings indented less than 30 stars.

 File: org.info,  Node: Global and local cycling,  Next: Initial visibility,  Up: Visibility Cycling
 
 2.2.1 Global and local cycling
 ------------------------------
 
 Outlines make it possible to hide parts of the text in the buffer.  Org
 uses just two commands, bound to ‘<TAB>’ and ‘S-<TAB>’ to change the
 visibility in the buffer.
 
 ‘<TAB>’ (‘org-cycle’)
      _Subtree cycling_: Rotate current subtree among the states
 
           ,-> FOLDED -> CHILDREN -> SUBTREE --.
           '-----------------------------------'
 
      Point must be on a headline for this to work(1).
 
 ‘S-<TAB>’ (‘org-global-cycle’)
 ‘C-u <TAB>’
      _Global cycling_: Rotate the entire buffer among the states
 
           ,-> OVERVIEW -> CONTENTS -> SHOW ALL --.
           '--------------------------------------'
 
      When ‘S-<TAB>’ is called with a numeric prefix argument N, view
      contents only up to headlines of level N.
 
      Note that inside tables (see *note Tables::), ‘S-<TAB>’ jumps to
      the previous field instead.
 
      You can run global cycling using ‘<TAB>’ only if point is at the
      very beginning of the buffer, but not on a headline, and
      ‘org-cycle-global-at-bob’ is set to a non-‘nil’ value.
 
 ‘C-u C-u <TAB>’ (‘org-cycle-set-startup-visibility’)
      Switch back to the startup visibility of the buffer (see *note
      Initial visibility::).
 
 ‘C-u C-u C-u <TAB>’ (‘org-show-all’)
      Show all, including drawers.
 
 ‘C-c C-r’ (‘org-reveal’)
      Reveal context around point, showing the current entry, the
      following heading and the hierarchy above.  It is useful for
      working near a location that has been exposed by a sparse tree
      command (see *note Sparse Trees::) or an agenda command (see *note
      Agenda Commands::).  With a prefix argument, show, on each level,
      all sibling headings.  With a double prefix argument, also show the
      entire subtree of the parent.
 
 ‘C-c C-k’ (‘org-show-branches’)
      Expose all the headings of the subtree, but not their bodies.
 
 ‘C-c <TAB>’ (‘org-show-children’)
      Expose all direct children of the subtree.  With a numeric prefix
      argument N, expose all children down to level N.
 
 ‘C-c C-x b’ (‘org-tree-to-indirect-buffer’)
      Show the current subtree in an indirect buffer(2).  With a numeric
      prefix argument N, go up to level N and then take that tree.  If N
      is negative then go up that many levels.  With a ‘C-u’ prefix, do
      not remove the previously used indirect buffer.
 
 ‘C-c C-x v’ (‘org-copy-visible’)
      Copy the _visible_ text in the region into the kill ring.
 
    ---------- Footnotes ----------
 
    (1) See, however, the option ‘org-cycle-emulate-tab’.
 
    (2) The indirect buffer contains the entire buffer, but is narrowed
 to the current tree.  Editing the indirect buffer also changes the
 original buffer, but without affecting visibility in that buffer.  For
 more information about indirect buffers, see *note GNU Emacs Manual:
 (emacs)Indirect Buffers.
 
 
 File: org.info,  Node: Initial visibility,  Next: Catching invisible edits,  Prev: Global and local cycling,  Up: Visibility Cycling
 
 2.2.2 Initial visibility
 ------------------------
 
 When Emacs first visits an Org file, the global state is set to
 ‘showeverything’, i.e., all file content is visible(1).  This can be
 configured through the variable ‘org-startup-folded’, or on a per-file
 basis by adding one of the following lines anywhere in the buffer:
 
      #+STARTUP: overview
      #+STARTUP: content
      #+STARTUP: showall
      #+STARTUP: show2levels
      #+STARTUP: show3levels
      #+STARTUP: show4levels
      #+STARTUP: show5levels
      #+STARTUP: showeverything
 
    Furthermore, any entries with a ‘VISIBILITY’ property (see *note
 Properties and Columns::) get their visibility adapted accordingly.
 Allowed values for this property are ‘folded’, ‘children’, ‘content’,
 and ‘all’.
 
 ‘C-u C-u <TAB>’ (‘org-cycle-set-startup-visibility’)
      Switch back to the startup visibility of the buffer, i.e., whatever
      is requested by startup options and ‘VISIBILITY’ properties in
      individual entries.
 
    ---------- Footnotes ----------
 
    (1) When ‘org-agenda-inhibit-startup’ is non-‘nil’, Org does not
 honor the default visibility state when first opening a file for the
 agenda (see *note Speeding Up Your Agendas::).
 
 
 File: org.info,  Node: Catching invisible edits,  Prev: Initial visibility,  Up: Visibility Cycling
 
 2.2.3 Catching invisible edits
 ------------------------------
 
 Sometimes you may inadvertently edit an invisible part of the buffer and
 be confused on what has been edited and how to undo the mistake.  By
 default, Org prevents such edits for a limited set of user commands.
 Users can control which commands are affected by customizing
 ‘org-fold-catch-invisible-edits-commands’.
 
    The strategy used to decide if a given edit is dangerous is
 controlled by ‘org-fold-catch-invisible-edits’.  See the docstring of
 this option on the available strategies.  Set the option to ‘nil’ to
 disable catching invisible edits completely.
 
 
 File: org.info,  Node: Motion,  Next: Structure Editing,  Prev: Visibility Cycling,  Up: Document Structure
 
 2.3 Motion
 ==========
 
 The following commands jump to other headlines in the buffer.
 
 ‘C-c C-n’ (‘org-next-visible-heading’)
      Next heading.
 
 ‘C-c C-p’ (‘org-previous-visible-heading’)
      Previous heading.
 
 ‘C-c C-f’ (‘org-forward-heading-same-level’)
      Next heading same level.
 
 ‘C-c C-b’ (‘org-backward-heading-same-level’)
      Previous heading same level.
 
 ‘C-c C-u’ (‘outline-up-heading’)
      Backward to higher level heading.
 
 ‘C-c C-j’ (‘org-goto’)
      Jump to a different place without changing the current outline
      visibility.  Shows the document structure in a temporary buffer,
      where you can use the following keys to find your destination:
 
      ‘<TAB>’                Cycle visibility.
      ‘<DOWN>’ / ‘<UP>’      Next/previous visible headline.
      ‘<RET>’                Select this location.
      ‘/’                    Do a Sparse-tree search
 
      The following keys work if you turn off ‘org-goto-auto-isearch’
 
      ‘n’ / ‘p’              Next/previous visible headline.
      ‘f’ / ‘b’              Next/previous headline same level.
      ‘u’                    One level up.
      ‘0’ ... ‘9’            Digit argument.
      ‘q’                    Quit.

 2.4 Structure Editing
 =====================
 
 ‘M-<RET>’ (‘org-meta-return’)
      Insert a new heading, item or row.
 
      If the command is used at the _beginning_ of a line, and if there
      is a heading or a plain list item (see *note Plain Lists::) at
      point, the new heading/item is created _before_ the current line.
      When used at the beginning of a regular line of text, turn that
      line into a heading.
 
      When this command is used in the middle of a line, the line is
      split and the rest of the line becomes the new item or headline.
      If you do not want the line to be split, customize
      ‘org-M-RET-may-split-line’.
 
      Calling the command with a ‘C-u’ prefix unconditionally inserts a
      new heading at the end of the current subtree, thus preserving its
      contents.  With a double ‘C-u C-u’ prefix, the new heading is
      created at the end of the parent subtree instead.
 
 ‘C-<RET>’ (‘org-insert-heading-respect-content’)
      Insert a new heading at the end of the current subtree.
 
 ‘M-S-<RET>’ (‘org-insert-todo-heading’)
      Insert new TODO entry with same level as current heading.  See also
      the variable ‘org-treat-insert-todo-heading-as-state-change’.
 
 ‘C-S-<RET>’ (‘org-insert-todo-heading-respect-content’)
      Insert new TODO entry with same level as current heading.  Like
      ‘C-<RET>’, the new headline is inserted after the current subtree.
 
 ‘<TAB>’ (‘org-cycle’)
      In a new entry with no text yet, the first ‘<TAB>’ demotes the
      entry to become a child of the previous one.  The next ‘<TAB>’
      makes it a parent, and so on, all the way to top level.  Yet
      another ‘<TAB>’, and you are back to the initial level.
 
 ‘M-<LEFT>’ (‘org-do-promote’)
 ‘M-<RIGHT>’ (‘org-do-demote’)
      Promote or demote current heading by one level.
 
      When there is an active region—i.e., when Transient Mark mode is
      active—promotion and demotion work on all headlines in the region.
      To select a region of headlines, it is best to place both point and
      mark at the beginning of a line, mark at the beginning of the first
      headline, and point at the line just after the last headline to
      change.
 
 ‘M-S-<LEFT>’ (‘org-promote-subtree’)
      Promote the current subtree by one level.
 
 ‘M-S-<RIGHT>’ (‘org-demote-subtree’)
      Demote the current subtree by one level.
 
 ‘M-<UP>’ (‘org-move-subtree-up’)
      Move subtree up, i.e., swap with previous subtree of same level.
 
 ‘M-<DOWN>’ (‘org-move-subtree-down’)
      Move subtree down, i.e., swap with next subtree of same level.
 
 ‘C-c @’ (‘org-mark-subtree’)
      Mark the subtree at point.  Hitting repeatedly marks subsequent
      subtrees of the same level as the marked subtree.
 
 ‘C-c C-x C-w’ (‘org-cut-subtree’)
      Kill subtree, i.e., remove it from buffer but save in kill ring.
      With a numeric prefix argument N, kill N sequential subtrees.
 
 ‘C-c C-x M-w’ (‘org-copy-subtree’)
      Copy subtree to kill ring.  With a numeric prefix argument N, copy
      the N sequential subtrees.
 
 ‘C-c C-x C-y’ (‘org-paste-subtree’)
      Yank subtree from kill ring.  This does modify the level of the
      subtree to make sure the tree fits in nicely at the yank position.
      The yank level can also be specified with a numeric prefix
      argument, or by yanking after a headline marker like ‘****’.  With
      ‘C-u’ prefix, force inserting as a sibling.  With ‘C-u C-u’ prefix
      argument, force inserting as a child.
 
 ‘C-y’ (‘org-yank’)
      Depending on the variables ‘org-yank-adjusted-subtrees’ and
      ‘org-yank-folded-subtrees’, Org’s internal ‘yank’ command pastes
      subtrees folded and in a clever way, using the same command as ‘C-c
      C-x C-y’.  With the default settings, no level adjustment takes
      place, but the yanked tree is folded unless doing so would swallow
      text previously visible.  Any prefix argument to this command
      forces a normal ‘yank’ to be executed, with the prefix passed
      along.  A good way to force a normal yank is ‘C-u C-y’.  If you use
      ‘yank-pop’ after a yank, it yanks previous kill items plainly,
      without adjustment and folding.
 
 ‘C-c C-x c’ (‘org-clone-subtree-with-time-shift’)
      Clone a subtree by making a number of sibling copies of it.  You
      are prompted for the number of copies to make, and you can also
      specify if any timestamps in the entry should be shifted.  This can
      be useful, for example, to create a number of tasks related to a
      series of lectures to prepare.  For more details, see the docstring
      of the command ‘org-clone-subtree-with-time-shift’.
 
 ‘C-c C-w’ (‘org-refile’)
      Refile entry or region to a different location.  See *note Refile
      and Copy::.
 
 ‘C-c ^’ (‘org-sort’)
      Sort same-level entries.  When there is an active region, all
      entries in the region are sorted.  Otherwise the children of the
      current headline are sorted.  The command prompts for the sorting
      method, which can be alphabetically, numerically, by time—first
      timestamp with active preferred, creation time, scheduled time,
      deadline time—by priority, by TODO keyword—in the sequence the
      keywords have been defined in the setup—or by the value of a
      property.  Reverse sorting is possible as well.  You can also
      supply your own function to extract the sorting key.  With a ‘C-u’
      prefix, sorting is case-sensitive.
 
 ‘C-x n s’ (‘org-narrow-to-subtree’)
      Narrow buffer to current subtree.
 
 ‘C-x n b’ (‘org-narrow-to-block’)
      Narrow buffer to current block.
 
 ‘C-x n w’ (‘widen’)
      Widen buffer to remove narrowing.
 
 ‘C-c *’ (‘org-toggle-heading’)
      Turn a normal line or plain list item into a headline—so that it
      becomes a subheading at its location.  Also turn a headline into a
      normal line by removing the stars.  If there is an active region,
      turn all lines in the region into headlines.  If the first line in
      the region was an item, turn only the item lines into headlines.
      Finally, if the first line is a headline, remove the stars from all
      headlines in the region.
 
    Note that when point is inside a table (see *note Tables::), the
 Meta-Cursor keys have different functionality.

 2.5 Sparse Trees
 ================
 
 An important feature of Org mode is the ability to construct _sparse
 trees_ for selected information in an outline tree, so that the entire
 document is folded as much as possible, but the selected information is
 made visible along with the headline structure above it(1).  Just try it
 out and you will see immediately how it works.
 
    Org mode contains several commands creating such trees, all these
 commands can be accessed through a dispatcher:
 
 ‘C-c /’ (‘org-sparse-tree’)
      This prompts for an extra key to select a sparse-tree creating
      command.
 
 ‘C-c / r’ or ‘C-c / /’ (‘org-occur’)
      Prompts for a regexp (see *note Regular Expressions::) and shows a
      sparse tree with all matches.  If the match is in a headline, the
      headline is made visible.  If the match is in the body of an entry,
      headline and body are made visible.  In order to provide minimal
      context, also the full hierarchy of headlines above the match is
      shown, as well as the headline following the match.  Each match is
      also highlighted; the highlights disappear when the buffer is
      changed by an editing command, or by pressing ‘C-c C-c’(2).  When
      called with a ‘C-u’ prefix argument, previous highlights are kept,
      so several calls to this command can be stacked.
 
 ‘M-g n’ or ‘M-g M-n’ (‘next-error’)
      Jump to the next sparse tree match in this buffer.
 
 ‘M-g p’ or ‘M-g M-p’ (‘previous-error’)
      Jump to the previous sparse tree match in this buffer.
 
    For frequently used sparse trees of specific search strings, you can
 use the variable ‘org-agenda-custom-commands’ to define fast keyboard
 access to specific sparse trees.  These commands will then be accessible
 through the agenda dispatcher (see *note Agenda Dispatcher::).  For
 example:
 
      (setq org-agenda-custom-commands
            '(("f" occur-tree "FIXME")))
 
 defines the key ‘f’ as a shortcut for creating a sparse tree matching
 the string ‘FIXME’.
 
    The other sparse tree commands select headings based on TODO
 keywords, tags, or properties and are discussed later in this manual.
 
    To print a sparse tree, you can use the Emacs command
 ‘ps-print-buffer-with-faces’ which does not print invisible parts of the
 document.  Or you can use the command ‘C-c C-e C-v’ to export only the
 visible part of the document and print the resulting file.
 
    ---------- Footnotes ----------
 
    (1) See also the variable ‘org-show-context-detail’ to decide how
 much context is shown around each match.
 
    (2) This depends on the option ‘org-remove-highlights-with-change’.
 
 
 File: org.info,  Node: Plain Lists,  Next: Drawers,  Prev: Sparse Trees,  Up: Document Structure
 
 2.6 Plain Lists
 ===============
 
 Within an entry of the outline tree, hand-formatted lists can provide
 additional structure.  They also provide a way to create lists of
 checkboxes (see *note Checkboxes::).  Org supports editing such lists,
 and every exporter (see *note Exporting::) can parse and format them.
 
    Org knows ordered lists, unordered lists, and description lists.
 
    • _Unordered_ list items start with ‘-’, ‘+’, or ‘*’(1) as bullets.
 
    • _Ordered_ list items start with a numeral followed by either a
      period or a right parenthesis(2), such as ‘1.’ or ‘1)’(3) If you
      want a list to start with a different value—e.g., 20—start the text
      of the item with ‘[@20]’(4).  Those constructs can be used in any
      item of the list in order to enforce a particular numbering.
 
    • _Description_ list items are unordered list items, and contain the
      separator ‘::’ to distinguish the description _term_ from the
      description.
 
    Items belonging to the same list must have the same indentation on
 the first line.  In particular, if an ordered list reaches number ‘10.’,
 then the 2-digit numbers must be written left-aligned with the other
 numbers in the list.  An item ends before the next line that is less or
 equally indented than its bullet/number.
 
    A list ends whenever every item has ended, which means before any
 line less or equally indented than items at top level.  It also ends
 before two blank lines.  In that case, all items are closed.  Here is an
 example:
 
      * Lord of the Rings
      My favorite scenes are (in this order)
      1. The attack of the Rohirrim
      2. Eowyn's fight with the witch king
         + this was already my favorite scene in the book
         + I really like Miranda Otto.
      3. Peter Jackson being shot by Legolas
         - on DVD only
         He makes a really funny face when it happens.
      8. [@8] <favorite scenes 4 to 8 are skipped for brevity>
      But in the end, no individual scenes matter but the film as a whole.
      Important actors in this film are:
      - Elijah Wood :: He plays Frodo
      - Sean Astin :: He plays Sam, Frodo's friend.  I still remember him
           very well from his role as Mikey Walsh in /The Goonies/.
 
    Org supports these lists by tuning filling and wrapping commands to
 deal with them correctly, and by exporting them properly (see *note
 Exporting::).  Since indentation is what governs the structure of these
 lists, many structural constructs like ‘#+BEGIN_’ blocks can be indented
 to signal that they belong to a particular item.
 
    If you find that using a different bullet for a sub-list—than that
 used for the current list-level—improves readability, customize the
 variable ‘org-list-demote-modify-bullet’.  To get a greater difference
 of indentation between items and theirs sub-items, customize
 ‘org-list-indent-offset’.
 
    The following commands act on items when point is in the first line
 of an item—the line with the bullet or number.  Some of them imply the
 application of automatic rules to keep list structure intact.  If some
 of these actions get in your way, configure ‘org-list-automatic-rules’
 to disable them individually.
 
 ‘<TAB>’ (‘org-cycle’)
      Items can be folded just like headline levels.  Normally this works
      only if point is on a plain list item.  For more details, see the
      variable ‘org-cycle-include-plain-lists’.  If this variable is set
      to ‘integrate’, plain list items are treated like low-level
      headlines.  The level of an item is then given by the indentation
      of the bullet/number.  Items are always subordinate to real
      headlines, however; the hierarchies remain completely separated.
      In a new item with no text yet, the first ‘<TAB>’ demotes the item
      to become a child of the previous one.  Subsequent ‘<TAB>’s move
      the item to meaningful levels in the list and eventually get it
      back to its initial position.
 
 ‘M-<RET>’ (‘org-insert-heading’)
      Insert new item at current level.  With a prefix argument, force a
      new heading (see *note Structure Editing::).  If this command is
      used in the middle of an item, that item is _split_ in two, and the
      second part becomes the new item(5).  If this command is executed
      _before item’s body_, the new item is created _before_ the current
      one.
 
 ‘M-S-<RET>’
      Insert a new item with a checkbox (see *note Checkboxes::).
 
 ‘S-<UP>’
 ‘S-<DOWN>’
      Jump to the previous/next item in the current list, but only if
      ‘org-support-shift-select’ is off(6).  If not, you can still use
      paragraph jumping commands like ‘C-<UP>’ and ‘C-<DOWN>’ to quite
      similar effect.
 
 ‘M-<UP>’
 ‘M-<DOWN>’
      Move the item including subitems up/down(7), i.e., swap with
      previous/next item of same indentation.  If the list is ordered,
      renumbering is automatic.
 
 ‘M-<LEFT>’
 ‘M-<RIGHT>’
      Decrease/increase the indentation of an item, leaving children
      alone.
 
 ‘M-S-<LEFT>’
 ‘M-S-<RIGHT>’
      Decrease/increase the indentation of the item, including subitems.
      Initially, the item tree is selected based on current indentation.
      When these commands are executed several times in direct
      succession, the initially selected region is used, even if the new
      indentation would imply a different hierarchy.  To use the new
      hierarchy, break the command chain by moving point.
 
      As a special case, using this command on the very first item of a
      list moves the whole list.  This behavior can be disabled by
      configuring ‘org-list-automatic-rules’.  The global indentation of
      a list has no influence on the text _after_ the list.
 
 ‘C-c C-c’
      If there is a checkbox (see *note Checkboxes::) in the item line,
      toggle the state of the checkbox.  In any case, verify bullets and
      indentation consistency in the whole list.
 
 ‘C-c -’
      Cycle the entire list level through the different itemize/enumerate
      bullets (‘-’, ‘+’, ‘*’, ‘1.’, ‘1)’) or a subset of them, depending
      on ‘org-plain-list-ordered-item-terminator’, the type of list, and
      its indentation.  With a numeric prefix argument N, select the Nth
      bullet from this list.  If there is an active region when calling
      this, all lines are converted to list items.  With a prefix
      argument, the selected text is changed into a single item.  If the
      first line already was a list item, any item marker is removed from
      the list.  Finally, even without an active region, a normal line is
      converted into a list item.
 
 ‘C-c *’
      Turn a plain list item into a headline—so that it becomes a
      subheading at its location.  See *note Structure Editing::, for a
      detailed explanation.
 
 ‘C-c C-*’
      Turn the whole plain list into a subtree of the current heading.
      Checkboxes (see *note Checkboxes::) become ‘TODO’, respectively
      ‘DONE’, keywords when unchecked, respectively checked.
 
 ‘S-<LEFT>’
 ‘S-<RIGHT>’
      This command also cycles bullet styles when point is in on the
      bullet or anywhere in an item line, details depending on
      ‘org-support-shift-select’.
 
 ‘C-c ^’
      Sort the plain list.  Prompt for the sorting method: numerically,
      alphabetically, by time, or by custom function.
 
    ---------- Footnotes ----------
 
    (1) When using ‘*’ as a bullet, lines must be indented so that they
 are not interpreted as headlines.  Also, when you are hiding leading
 stars to get a clean outline view, plain list items starting with a star
 may be hard to distinguish from true headlines.  In short: even though
 ‘*’ is supported, it may be better to not use it for plain list items.
 
    (2) You can filter out any of them by configuring
 ‘org-plain-list-ordered-item-terminator’.
 
    (3) You can also get ‘a.’, ‘A.’, ‘a)’ and ‘A)’ by configuring
 ‘org-list-allow-alphabetical’.  To minimize confusion with normal text,
 those are limited to one character only.  Beyond that limit, bullets
 automatically become numbers.
 
    (4) If there’s a checkbox in the item, the cookie must be put
 _before_ the checkbox.  If you have activated alphabetical lists, you
 can also use counters like ‘[@b]’.
 
    (5) If you do not want the item to be split, customize the variable
 ‘org-M-RET-may-split-line’.
 
    (6) If you want to cycle around items that way, you may customize
 ‘org-list-use-circular-motion’.
 
    (7) See ‘org-list-use-circular-motion’ for a cyclic behavior.
 
 
 File: org.info,  Node: Drawers,  Next: Blocks,  Prev: Plain Lists,  Up: Document Structure
 
 2.7 Drawers
 ===========
 
 Sometimes you want to keep information associated with an entry, but you
 normally do not want to see it.  For this, Org mode has _drawers_.  They
 can contain anything but a headline and another drawer.  Drawers look
 like this:
 
      ** This is a headline
      Still outside the drawer
      :DRAWERNAME:
      This is inside the drawer.
      :END:
      After the drawer.
 
    You can interactively insert a drawer at point by calling
 ‘org-insert-drawer’, which is bound to ‘C-c C-x d’.  With an active
 region, this command puts the region inside the drawer.  With a prefix
 argument, this command calls non-interactive function
 ‘org-insert-property-drawer’, which creates a ‘PROPERTIES’ drawer right
 below the current headline.  Org mode uses this special drawer for
 storing properties (see *note Properties and Columns::).  You cannot use
 it for anything else.
 
    Completion over drawer keywords is also possible using ‘M-<TAB>’(1).
 
    Visibility cycling (see *note Visibility Cycling::) on the headline
 hides and shows the entry, but keep the drawer collapsed to a single
 line.  In order to look inside the drawer, you need to move point to the
 drawer line and press ‘<TAB>’ there.
 
    You can also arrange for state change notes (see *note Tracking TODO
 state changes::) and clock times (see *note Clocking Work Time::) to be
 stored in a ‘LOGBOOK’ drawer.  If you want to store a quick note there,
 in a similar way to state changes, use
 
 ‘C-c C-z’
      Add a time-stamped note to the ‘LOGBOOK’ drawer.
 
    ---------- Footnotes ----------
 
    (1) Many desktops intercept ‘M-<TAB>’ to switch windows.  Use ‘C-M-i’
 or ‘<ESC> <TAB>’ instead.

 2.8 Blocks
 ==========
 
 Org mode uses ‘#+BEGIN’ ... ‘#+END’ blocks for various purposes from
 including source code examples (see *note Literal Examples::) to
 capturing time logging information (see *note Clocking Work Time::).
 These blocks can be folded and unfolded by pressing ‘<TAB>’ in the
 ‘#+BEGIN’ line.  You can also get all blocks folded at startup by
 configuring the variable ‘org-hide-block-startup’ or on a per-file basis
 by using
 
      #+STARTUP: hideblocks
      #+STARTUP: nohideblocks

 3 Tables
 ********
 
 Org comes with a fast and intuitive table editor.  Spreadsheet-like
 calculations are supported using the Emacs Calc package (see *note GNU
 Emacs Calculator Manual: (calc)Top.).
 
 * Menu:
 
 * Built-in Table Editor::        Simple tables.
 * Column Width and Alignment::   Overrule the automatic settings.
 * Column Groups::                Grouping to trigger vertical lines.
 * Orgtbl Mode::                  The table editor as minor mode.
 * The Spreadsheet::              The table editor has spreadsheet capabilities.
 * Org Plot::                     Plotting from Org tables.
 
 
 File: org.info,  Node: Built-in Table Editor,  Next: Column Width and Alignment,  Up: Tables
 
 3.1 Built-in Table Editor
 =========================
 
 Org makes it easy to format tables in plain ASCII.  Any line with ‘|’ as
 the first non-whitespace character is considered part of a table.  ‘|’
 is also the column separator(1).  Moreover, a line starting with ‘|-’ is
 a horizontal rule.  It separates rows explicitly.  Rows before the first
 horizontal rule are header lines.  A table might look like this:
 
      | Name  | Phone | Age |
      |-------+-------+-----|
      | Peter |  1234 |  17 |
      | Anna  |  4321 |  25 |
 
    A table is re-aligned automatically each time you press ‘<TAB>’,
 ‘<RET>’ or ‘C-c C-c’ inside the table.  ‘<TAB>’ also moves to the next
 field—‘<RET>’ to the next row—and creates new table rows at the end of
 the table or before horizontal lines.  The indentation of the table is
 set by the first line.  Horizontal rules are automatically expanded on
 every re-align to span the whole table width.  So, to create the above
 table, you would only type
 
      |Name|Phone|Age|
      |-
 
 and then press ‘<TAB>’ to align the table and start filling in fields.
 Even faster would be to type ‘|Name|Phone|Age’ followed by ‘C-c <RET>’.
 
    When typing text into a field, Org treats ‘<DEL>’, ‘Backspace’, and
 all character keys in a special way, so that inserting and deleting
 avoids shifting other fields.  Also, when typing _immediately_ after
 point was moved into a new field with ‘<TAB>’, ‘S-<TAB>’ or ‘<RET>’, the
 field is automatically made blank.  If this behavior is too
 unpredictable for you, configure the option
 ‘org-table-auto-blank-field’.
 
 Creation and conversion
 -----------------------
 
 ‘C-c |’ (‘org-table-create-or-convert-from-region’)
      Convert the active region to table.  If every line contains at
      least one ‘<TAB>’ character, the function assumes that the material
      is tab separated.  If every line contains a comma, comma-separated
      values (CSV) are assumed.  If not, lines are split at whitespace
      into fields.  You can use a prefix argument to force a specific
      separator: ‘C-u’ forces CSV, ‘C-u C-u’ forces ‘<TAB>’, ‘C-u C-u
      C-u’ prompts for a regular expression to match the separator, and a
      numeric argument N indicates that at least N consecutive spaces, or
      alternatively a ‘<TAB>’ will be the separator.
 
      If there is no active region, this command creates an empty Org
      table.  But it is easier just to start typing, like ‘| N a m e | P
      h o n e | A g e <RET> | - <TAB>’.
 
 Re-aligning and field motion
 ----------------------------
 
 ‘C-c C-c’ (‘org-table-align’)
      Re-align the table without moving point.
 
 ‘<TAB>’ (‘org-table-next-field’)
      Re-align the table, move to the next field.  Creates a new row if
      necessary.
 
 ‘M-x org-table-blank-field’
      Blank the current table field or active region.
 
 ‘S-<TAB>’ (‘org-table-previous-field’)
      Re-align, move to previous field.
 
 ‘<RET>’ (‘org-table-next-row’)
      Re-align the table and move down to next row.  Creates a new row if
      necessary.  At the beginning or end of a line, ‘<RET>’ still
      inserts a new line, so it can be used to split a table.
 
 ‘M-a’ (‘org-table-beginning-of-field’)
      Move to beginning of the current table field, or on to the previous
      field.
 
 ‘M-e’ (‘org-table-end-of-field’)
      Move to end of the current table field, or on to the next field.
 
 Column and row editing
 ----------------------
 
 ‘M-<LEFT>’ (‘org-table-move-column-left’)
      Move the current column left.
 
 ‘M-<RIGHT>’ (‘org-table-move-column-right’)
      Move the current column right.
 
 ‘M-S-<LEFT>’ (‘org-table-delete-column’)
      Kill the current column.
 
 ‘M-S-<RIGHT>’ (‘org-table-insert-column’)
      Insert a new column at point position.  Move the recent column and
      all cells to the right of this column to the right.
 
 ‘M-<UP>’ (‘org-table-move-row-up’)
      Move the current row up.
 
 ‘M-<DOWN>’ (‘org-table-move-row-down’)
      Move the current row down.
 
 ‘M-S-<UP>’ (‘org-table-kill-row’)
      Kill the current row or horizontal line.
 
 ‘S-<UP>’ (‘org-table-move-cell-up’)
      Move cell up by swapping with adjacent cell.
 
 ‘S-<DOWN>’ (‘org-table-move-cell-down’)
      Move cell down by swapping with adjacent cell.
 
 ‘S-<LEFT>’ (‘org-table-move-cell-left’)
      Move cell left by swapping with adjacent cell.
 
 ‘S-<RIGHT>’ (‘org-table-move-cell-right’)
      Move cell right by swapping with adjacent cell.
 
 ‘M-S-<DOWN>’ (‘org-table-insert-row’)
      Insert a new row above the current row.  With a prefix argument,
      the line is created below the current one.
 
 ‘C-c -’ (‘org-table-insert-hline’)
      Insert a horizontal line below current row.  With a prefix
      argument, the line is created above the current line.
 
 ‘C-c <RET>’ (‘org-table-hline-and-move’)
      Insert a horizontal line below current row, and move point into the
      row below that line.
 
 ‘C-c ^’ (‘org-table-sort-lines’)
      Sort the table lines in the region.  The position of point
      indicates the column to be used for sorting, and the range of lines
      is the range between the nearest horizontal separator lines, or the
      entire table.  If point is before the first column, you are
      prompted for the sorting column.  If there is an active region, the
      mark specifies the first line and the sorting column, while point
      should be in the last line to be included into the sorting.  The
      command prompts for the sorting type, alphabetically, numerically,
      or by time.  You can sort in normal or reverse order.  You can also
      supply your own key extraction and comparison functions.  When
      called with a prefix argument, alphabetic sorting is
      case-sensitive.
 
 Regions
 -------
 
 ‘C-c C-x M-w’ (‘org-table-copy-region’)
      Copy a rectangular region from a table to a special clipboard.
      Point and mark determine edge fields of the rectangle.  If there is
      no active region, copy just the current field.  The process ignores
      horizontal separator lines.
 
 ‘C-c C-x C-w’ (‘org-table-cut-region’)
      Copy a rectangular region from a table to a special clipboard, and
      blank all fields in the rectangle.  So this is the “cut” operation.
 
 ‘C-c C-x C-y’ (‘org-table-paste-rectangle’)
      Paste a rectangular region into a table.  The upper left corner
      ends up in the current field.  All involved fields are overwritten.
      If the rectangle does not fit into the present table, the table is
      enlarged as needed.  The process ignores horizontal separator
      lines.
 
 ‘M-<RET>’ (‘org-table-wrap-region’)
      Split the current field at point position and move the rest to the
      line below.  If there is an active region, and both point and mark
      are in the same column, the text in the column is wrapped to
      minimum width for the given number of lines.  A numeric prefix
      argument may be used to change the number of desired lines.  If
      there is no region, but you specify a prefix argument, the current
      field is made blank, and the content is appended to the field
      above.
 
 Calculations
 ------------
 
 ‘C-c +’ (‘org-table-sum’)
      Sum the numbers in the current column, or in the rectangle defined
      by the active region.  The result is shown in the echo area and can
      be inserted with ‘C-y’.
 
 ‘S-<RET>’ (‘org-table-copy-down’)
      When current field is empty, copy from first non-empty field above.
      When not empty, copy current field down to next row and move point
      along with it.
 
      Depending on the variable ‘org-table-copy-increment’, integer and
      time stamp field values, and fields prefixed or suffixed with a
      whole number, can be incremented during copy.  Also, a ‘0’ prefix
      argument temporarily disables the increment.
 
      This key is also used by shift-selection and related modes (see
      *note Conflicts::).
 
 Miscellaneous
 -------------
 
 ‘C-c `’ (‘org-table-edit-field’)
      Edit the current field in a separate window.  This is useful for
      fields that are not fully visible (see *note Column Width and
      Alignment::).  When called with a ‘C-u’ prefix, just make the full
      field visible, so that it can be edited in place.  When called with
      two ‘C-u’ prefixes, make the editor window follow point through the
      table and always show the current field.  The follow mode exits
      automatically when point leaves the table, or when you repeat this
      command with ‘C-u C-u C-c `’.
 
 ‘M-x org-table-import’
      Import a file as a table.  The table should be TAB or whitespace
      separated.  Use, for example, to import a spreadsheet table or data
      from a database, because these programs generally can write
      TAB-separated text files.  This command works by inserting the file
      into the buffer and then converting the region to a table.  Any
      prefix argument is passed on to the converter, which uses it to
      determine the separator.
 
 ‘C-c |’ (‘org-table-create-or-convert-from-region’)
      Tables can also be imported by pasting tabular text into the Org
      buffer, selecting the pasted text with ‘C-x C-x’ and then using the
      ‘C-c |’ command (see *note Creation and conversion::).
 
 ‘M-x org-table-export’
      Export the table, by default as a TAB-separated file.  Use for data
      exchange with, for example, spreadsheet or database programs.  The
      format used to export the file can be configured in the variable
      ‘org-table-export-default-format’.  You may also use properties
      ‘TABLE_EXPORT_FILE’ and ‘TABLE_EXPORT_FORMAT’ to specify the file
      name and the format for table export in a subtree.  Org supports
      quite general formats for exported tables.  The exporter format is
      the same as the format used by Orgtbl radio tables, see *note
      Translator functions::, for a detailed description.
 
 ‘M-x org-table-header-line-mode’
      Turn on the display of the first data row of the table at point in
      the window header line when this first row is not visible anymore
      in the buffer.  You can activate this minor mode by default by
      setting the option ‘org-table-header-line-p’ to ‘t’.
 
 ‘M-x org-table-transpose-table-at-point’
      Transpose the table at point and eliminate hlines.
 
    ---------- Footnotes ----------
 
    (1) To insert a vertical bar into a table field, use ‘\vert’ or,
 inside a word ‘abc\vert{}def’.

 3.2 Column Width and Alignment
 ==============================
 
 The width of columns is automatically determined by the table editor.
 The alignment of a column is determined automatically from the fraction
 of number-like versus non-number fields in the column.
 
    Editing a field may modify alignment of the table.  Moving a
 contiguous row or column—i.e., using ‘<TAB>’ or ‘<RET>’—automatically
 re-aligns it.  If you want to disable this behavior, set
 ‘org-table-automatic-realign’ to ‘nil’.  In any case, you can always
 align manually a table:
 
 ‘C-c C-c’ (‘org-table-align’)
      Align the current table.
 
    Setting the option ‘org-startup-align-all-tables’ re-aligns all
 tables in a file upon visiting it.  You can also set this option on a
 per-file basis with:
 
      #+STARTUP: align
      #+STARTUP: noalign
 
    Sometimes a single field or a few fields need to carry more text,
 leading to inconveniently wide columns.  Maybe you want to hide away
 several columns or display them with a fixed width, regardless of
 content, as shown in the following example.
 
      |---+---------------------+--------|           |---+-------…+…|
      |   | <6>                 |        |           |   | <6>   …|…|
      | 1 | one                 | some   |   ----\   | 1 | one   …|…|
      | 2 | two                 | boring |   ----/   | 2 | two   …|…|
      | 3 | This is a long text | column |           | 3 | This i…|…|
      |---+---------------------+--------|           |---+-------…+…|
 
    To set the width of a column, one field anywhere in the column may
 contain just the string ‘<N>’ where N specifies the width as a number of
 characters.  You control displayed width of columns with the following
 tools:
 
 ‘C-c <TAB>’ (‘org-table-toggle-column-width’)
      Shrink or expand current column.
 
      If a width cookie specifies a width W for the column, shrinking it
      displays the first W visible characters only.  Otherwise, the
      column is shrunk to a single character.
 
      When called before the first column or after the last one, ask for
      a list of column ranges to operate on.
 
 ‘C-u C-c <TAB>’ (‘org-table-shrink’)
      Shrink all columns with a column width.  Expand the others.
 
 ‘C-u C-u C-c <TAB>’ (‘org-table-expand’)
      Expand all columns.
 
    To see the full text of a shrunk field, hold the mouse over it: a
 tool-tip window then shows the full contents of the field.
 Alternatively, ‘C-h .’ (‘display-local-help’) reveals them, too.  For
 convenience, any change near the shrunk part of a column expands it.
 
    Setting the option ‘org-startup-shrink-all-tables’ shrinks all
 columns containing a width cookie in a file the moment it is visited.
 You can also set this option on a per-file basis with:
 
      #+STARTUP: shrink
 
    If you would like to overrule the automatic alignment of number-rich
 columns to the right and of string-rich columns to the left, you can use
 ‘<r>’, ‘<c>’ or ‘<l>’ in a similar fashion.  You may also combine
 alignment and field width like this: ‘<r10>’.
 
    Lines which only contain these formatting cookies are removed
 automatically upon exporting the document.

 3.3 Column Groups
 =================
 
 When Org exports tables, it does so by default without vertical lines
 because that is visually more satisfying in general.  Occasionally
 however, vertical lines can be useful to structure a table into groups
 of columns, much like horizontal lines can do for groups of rows.  In
 order to specify column groups, you can use a special row where the
 first field contains only ‘/’.  The further fields can either contain
 ‘<’ to indicate that this column should start a group, ‘>’ to indicate
 the end of a column, or ‘<>’ (no space between ‘<’ and ‘>’) to make a
 column a group of its own.  Upon export, boundaries between column
 groups are marked with vertical lines.  Here is an example:
 
      | N | N^2 | N^3 | N^4 | sqrt(n) | sqrt[4](N) |
      |---+-----+-----+-----+---------+------------|
      | / |  <  |     |  >  |       < |          > |
      | 1 |  1  |  1  |  1  |       1 |          1 |
      | 2 |  4  |  8  | 16  |  1.4142 |     1.1892 |
      | 3 |  9  | 27  | 81  |  1.7321 |     1.3161 |
      |---+-----+-----+-----+---------+------------|
      #+TBLFM: $2=$1^2::$3=$1^3::$4=$1^4::$5=sqrt($1)::$6=sqrt(sqrt(($1)))
 
    It is also sufficient to just insert the column group starters after
 every vertical line you would like to have:
 
      | N | N^2 | N^3 | N^4 | sqrt(n) | sqrt[4](N) |
      |---+-----+-----+-----+---------+------------|
      | / | <   |     |     | <       |            |

 3.4 The Orgtbl Minor Mode
 =========================
 
 If you like the intuitive way the Org table editor works, you might also
 want to use it in other modes like Text mode or Mail mode.  The minor
 mode Orgtbl mode makes this possible.  You can always toggle the mode
 with ‘M-x orgtbl-mode’.  To turn it on by default, for example in
 Message mode, use
 
      (add-hook 'message-mode-hook #'turn-on-orgtbl)
 
    Furthermore, with some special setup, it is possible to maintain
 tables in arbitrary syntax with Orgtbl mode.  For example, it is
 possible to construct LaTeX tables with the underlying ease and power of
 Orgtbl mode, including spreadsheet capabilities.  For details, see *note
 Tables in Arbitrary Syntax::.

 3.5 The Spreadsheet
 ===================
 
 The table editor makes use of the Emacs Calc package to implement
 spreadsheet-like capabilities.  It can also evaluate Emacs Lisp forms to
 derive fields from other fields.  While fully featured, Org’s
 implementation is not identical to other spreadsheets.  For example, Org
 knows the concept of a _column formula_ that will be applied to all
 non-header fields in a column without having to copy the formula to each
 relevant field.  There is also a formula debugger, and a formula editor
 with features for highlighting fields in the table corresponding to the
 references at point in the formula, moving these references by arrow
 keys.

 3.5.1 References
 ----------------
 
 To compute fields in the table from other fields, formulas must
 reference other fields or ranges.  In Org, fields can be referenced by
 name, by absolute coordinates, and by relative coordinates.  To find out
 what the coordinates of a field are, press ‘C-c ?’ in that field, or
 press ‘C-c }’ to toggle the display of a grid.
 
 Field references
 ................
 
 Formulas can reference the value of another field in two ways.  Like in
 any other spreadsheet, you may reference fields with a letter/number
 combination like ‘B3’, meaning the second field in the third row.
 However, Org prefers to use another, more general representation that
 looks like this:(1)
 
      @ROW$COLUMN
 
    Column specifications can be absolute like ‘$1’, ‘$2’, ..., ‘$N’, or
 relative to the current column, i.e., the column of the field which is
 being computed, like ‘$+1’ or ‘$-2’.  ‘$<’ and ‘$>’ are immutable
 references to the first and last column, respectively, and you can use
 ‘$>>>’ to indicate the third column from the right.
 
    The row specification only counts data lines and ignores horizontal
 separator lines, or “hlines”.  Like with columns, you can use absolute
 row numbers ‘@1’, ‘@2’, ..., ‘@N’, and row numbers relative to the
 current row like ‘@+3’ or ‘@-1’.  ‘@<’ and ‘@>’ are immutable references
 the first and last row in the table, respectively.  You may also specify
 the row relative to one of the hlines: ‘@I’ refers to the first hline,
 ‘@II’ to the second, etc.  ‘@-I’ refers to the first such line above the
 current line, ‘@+I’ to the first such line below the current line.  You
 can also write ‘@III+2’ which is the second data line after the third
 hline in the table.
 
    ‘@0’ and ‘$0’ refer to the current row and column, respectively,
 i.e., to the row/column for the field being computed.  Also, if you omit
 either the column or the row part of the reference, the current
 row/column is implied.
 
    Org’s references with _unsigned_ numbers are fixed references in the
 sense that if you use the same reference in the formula for two
 different fields, the same field is referenced each time.  Org’s
 references with _signed_ numbers are floating references because the
 same reference operator can reference different fields depending on the
 field being calculated by the formula.
 
    Here are a few examples:
 
 ‘@2$3’         2nd row, 3rd column (same as ‘C2’)
 ‘$5’           column 5 in the current row (same as ‘E&’)
 ‘@2’           current column, row 2
 ‘@-1$-3’       field one row up, three columns to the left
 ‘@-I$2’        field just under hline above current row, column 2
 ‘@>$5’         field in the last row, in column 5
 
 Range references
 ................
 
 You may reference a rectangular range of fields by specifying two field
 references connected by two dots ‘..’.  The ends are included in the
 range.  If both fields are in the current row, you may simply use
 ‘$2..$7’, but if at least one field is in a different row, you need to
 use the general ‘@ROW$COLUMN’ format at least for the first field, i.e.,
 the reference must start with ‘@’ in order to be interpreted correctly.
 Examples:
 
 ‘$1..$3’       first three fields in the current row
 ‘$P..$Q’       range, using column names (see
                *note Advanced features::)
 ‘$<<<..$>>’    start in third column, continue to the last but one
 ‘@2$1..@4$3’   nine fields between these two fields (same as ‘A2..C4’)
 ‘@-1$-2..@-1’  3 fields in the row above, starting from 2 columns on
                the left
 ‘@I..II’       between first and second hline, short for ‘@I..@II’
 
 Range references return a vector of values that can be fed into Calc
 vector functions.  Empty fields in ranges are normally suppressed, so
 that the vector contains only the non-empty fields.  For other options
 with the mode switches ‘E’, ‘N’ and examples, see *note Formula syntax
 for Calc::.
 
 Field coordinates in formulas
 .............................
 
 One of the very first actions during evaluation of Calc formulas and
 Lisp formulas is to substitute ‘@#’ and ‘$#’ in the formula with the row
 or column number of the field where the current result will go to.  The
 traditional Lisp formula equivalents are ‘org-table-current-dline’ and
 ‘org-table-current-column’.  Examples:
 
 ‘if(@# % 2, $#, string(""))’
      Insert column number on odd rows, set field to empty on even rows.
 
 ‘$2 = '(identity remote(FOO, @@#$1))’
      Copy text or values of each row of column 1 of the table named FOO
      into column 2 of the current table.
 
 ‘@3 = 2 * remote(FOO, @1$$#)’
      Insert the doubled value of each column of row 1 of the table named
      FOO into row 3 of the current table.
 
 For the second and third examples, table FOO must have at least as many
 rows or columns as the current table.  Note that this is inefficient(2)
 for large number of rows.
 
 Named references
 ................
 
 ‘$name’ is interpreted as the name of a column, parameter or constant.
 Constants are defined globally through the variable
 ‘org-table-formula-constants’, and locally—for the file—through a line
 like this example:
 
      #+CONSTANTS: c=299792458. pi=3.14 eps=2.4e-6
 
    Also, properties (see *note Properties and Columns::) can be used as
 constants in table formulas: for a property ‘Xyz’ use the name
 ‘$PROP_Xyz’, and the property will be searched in the current outline
 entry and in the hierarchy above it.  If you have the ‘constants.el’
 package, it will also be used to resolve constants, including natural
 constants like ‘$h’ for Planck’s constant, and units like ‘$km’ for
 kilometers(3).  Column names and parameters can be specified in special
 table lines.  These are described below, see *note Advanced features::.
 All names must start with a letter, and further consist of letters and
 numbers.
 
 Remote references
 .................
 
 You may also reference constants, fields and ranges from a different
 table, either in the current file or even in a different file.  The
 syntax is
 
      remote(NAME,REF)
 
 where NAME can be the name of a table in the current file as set by a
 ‘#+NAME:’ line before the table.  It can also be the ID of an entry,
 even in a different file, and the reference then refers to the first
 table in that entry.  REF is an absolute field or range reference as
 described above for example ‘@3$3’ or ‘$somename’, valid in the
 referenced table.
 
    When NAME has the format ‘@ROW$COLUMN’, it is substituted with the
 name or ID found in this field of the current table.  For example
 ‘remote($1, @@>$2)’ ⇒ ‘remote(year_2013, @@>$1)’.  The format ‘B3’ is
 not supported because it can not be distinguished from a plain table
 name or ID.
 
    ---------- Footnotes ----------
 
    (1) Org understands references typed by the user as ‘B4’, but it does
 not use this syntax when offering a formula for editing.  You can
 customize this behavior using the variable
 ‘org-table-use-standard-references’.
 
    (2) The computation time scales as O(N^2) because table FOO is parsed
 for each field to be copied.
 
    (3) The file ‘constants.el’ can supply the values of constants in two
 different unit systems, ‘SI’ and ‘cgs’.  Which one is used depends on
 the value of the variable ‘constants-unit-system’.  You can use the
 ‘STARTUP’ options ‘constSI’ and ‘constcgs’ to set this value for the
 current buffer.

 3.5.2 Formula syntax for Calc
 -----------------------------
 
 A formula can be any algebraic expression understood by the Emacs Calc
 package.  Note that Calc has the non-standard convention that ‘/’ has
 lower precedence than ‘*’, so that ‘a/b*c’ is interpreted as
 ‘(a/(b*c))’.  Before evaluation by ‘calc-eval’ (see *note Calling Calc
 from Your Lisp Programs: (calc)Calling Calc from Your Programs.),
 variable substitution takes place according to the rules described
 above.
 
    The range vectors can be directly fed into the Calc vector functions
 like ‘vmean’ and ‘vsum’.
 
    A formula can contain an optional mode string after a semicolon.
 This string consists of flags to influence Calc and other modes during
 execution.  By default, Org uses the standard Calc modes (precision 12,
 angular units degrees, fraction and symbolic modes off).  The display
 format, however, has been changed to ‘(float 8)’ to keep tables compact.
 The default settings can be configured using the variable
 ‘org-calc-default-modes’.
 
 ‘p20’
      Set the internal Calc calculation precision to 20 digits.
 
 ‘n3’, ‘s3’, ‘e2’, ‘f4’
      Normal, scientific, engineering or fixed format of the result of
      Calc passed back to Org.  Calc formatting is unlimited in precision
      as long as the Calc calculation precision is greater.
 
 ‘D’, ‘R’
      Degree and radian angle modes of Calc.
 
 ‘F’, ‘S’
      Fraction and symbolic modes of Calc.
 
 ‘u’
      Units simplification mode of Calc.  Calc is also a symbolic
      calculator and is capable of working with values having a unit,
      represented with numerals followed by a unit string in Org table
      cells.  This mode instructs Calc to simplify the units in the
      computed expression before returning the result.
 
 ‘T’, ‘t’, ‘U’
      Duration computations in Calc or Lisp, *note Durations and time
      values::.
 
 ‘E’
      If and how to consider empty fields.  Without ‘E’ empty fields in
      range references are suppressed so that the Calc vector or Lisp
      list contains only the non-empty fields.  With ‘E’ the empty fields
      are kept.  For empty fields in ranges or empty field references the
      value ‘nan’ (not a number) is used in Calc formulas and the empty
      string is used for Lisp formulas.  Add ‘N’ to use 0 instead for
      both formula types.  For the value of a field the mode ‘N’ has
      higher precedence than ‘E’.
 
 ‘N’
      Interpret all fields as numbers, use 0 for non-numbers.  See the
      next section to see how this is essential for computations with
      Lisp formulas.  In Calc formulas it is used only occasionally
      because there number strings are already interpreted as numbers
      without ‘N’.
 
 ‘L’
      Literal, for Lisp formulas only.  See the next section.
 
    Unless you use large integer numbers or high-precision calculation
 and display for floating point numbers you may alternatively provide a
 ‘printf’ format specifier to reformat the Calc result after it has been
 passed back to Org instead of letting Calc already do the formatting(1).
 A few examples:
 
 ‘$1+$2’              Sum of first and second field
 ‘$1+$2;%.2f’         Same, format result to two decimals
 ‘exp($2)+exp($1)’    Math functions can be used
 ‘$0;%.1f’            Reformat current cell to 1 decimal
 ‘($3-32)*5/9’        Degrees F → C conversion
 ‘$c/$1/$cm’          Hz → cm conversion, using ‘constants.el’
 ‘tan($1);Dp3s1’      Compute in degrees, precision 3, display SCI 1
 ‘sin($1);Dp3%.1e’    Same, but use ‘printf’ specifier for display
 ‘vmean($2..$7)’      Compute column range mean, using vector function
 ‘vmean($2..$7);EN’   Same, but treat empty fields as 0
 ‘taylor($3,x=7,2)’   Taylor series of $3, at x=7, second degree
 
    Calc also contains a complete set of logical operations (see *note
 Logical Operations: (calc)Logical Operations.).  For example
 
 ‘if($1 < 20, teen, string(""))’
      ‘"teen"’ if age ‘$1’ is less than 20, else the Org table result
      field is set to empty with the empty string.
 
 ‘if("$1" =​= "nan" || "$2" =​= "nan", string(""), $1 + $2); E f-1’
      Sum of the first two columns.  When at least one of the input
      fields is empty the Org table result field is set to empty.  ‘E’ is
      required to not convert empty fields to 0.  ‘f-1’ is an optional
      Calc format string similar to ‘%.1f’ but leaves empty results
      empty.
 
 ‘if(typeof(vmean($1..$7)) =​= 12, string(""), vmean($1..$7)); E’
      Mean value of a range unless there is any empty field.  Every field
      in the range that is empty is replaced by ‘nan’ which lets ‘vmean’
      result in ‘nan’.  Then ‘typeof =’ 12= detects the ‘nan’ from
      ‘vmean’ and the Org table result field is set to empty.  Use this
      when the sample set is expected to never have missing values.
 
 ‘if("$1..$7" =​= "[]", string(""), vmean($1..$7))’
      Mean value of a range with empty fields skipped.  Every field in
      the range that is empty is skipped.  When all fields in the range
      are empty the mean value is not defined and the Org table result
      field is set to empty.  Use this when the sample set can have a
      variable size.
 
 ‘vmean($1..$7); EN’
      To complete the example before: Mean value of a range with empty
      fields counting as samples with value 0.  Use this only when
      incomplete sample sets should be padded with 0 to the full size.
 
    You can add your own Calc functions defined in Emacs Lisp with
 ‘defmath’ and use them in formula syntax for Calc.
 
    ---------- Footnotes ----------
 
    (1) The printf reformatting is limited in precision because the value
 passed to it is converted into an “integer” or “double”.  The “integer”
 is limited in size by truncating the signed value to 32 bits.  The
 “double” is limited in precision to 64 bits overall which leaves
 approximately 16 significant decimal digits.

 3.5.3 Emacs Lisp forms as formulas
 ----------------------------------
 
 It is also possible to write a formula in Emacs Lisp.  This can be
 useful for string manipulation and control structures, if Calc’s
 functionality is not enough.
 
    A formula is evaluated as a Lisp form when it starts with a
 single-quote followed by an opening parenthesis.  Cell table references
 are interpolated into the Lisp form before execution.  The evaluation
 should return either a string or a number.  Evaluation modes and a
 ‘printf’ format used to render the returned values can be specified
 after a semicolon.
 
    By default, references are interpolated as literal Lisp strings: the
 field content is replaced in the Lisp form stripped of leading and
 trailing white space and surrounded in double-quotes.  For example:
 
      '(concat $1 $2)
 
 concatenates the content of columns 1 and column 2.
 
    When the ‘N’ flag is used, all referenced elements are parsed as
 numbers and interpolated as Lisp numbers, without quotes.  Fields that
 cannot be parsed as numbers are interpolated as zeros.  For example:
 
      '(+ $1 $2);N
 
 adds columns 1 and 2, equivalent to Calc’s ‘$1+$2’.  Ranges are inserted
 as space-separated fields, so they can be embedded in list or vector
 syntax.  For example:
 
      '(apply '+ '($1..$4));N
 
 computes the sum of columns 1 to 4, like Calc’s ‘vsum($1..$4)’.
 
    When the ‘L’ flag is used, all fields are interpolated literally: the
 cell content is replaced in the Lisp form stripped of leading and
 trailing white space and without quotes.  If a reference is intended to
 be interpreted as a string by the Lisp form, the reference operator
 itself should be enclosed in double-quotes, like ‘"$3"’.  The ‘L’ flag
 is useful when strings and numbers are used in the same Lisp form.  For
 example:
 
      '(substring "$1" $2 $3);L
 
 extracts the part of the string in column 1 between the character
 positions specified in the integers in column 2 and 3 and it is easier
 to read than the equivalent:
 
      '(substring $1 (string-to-number $2) (string-to-number $3))
 
    When the formula itself contains ‘;’ symbol, Org mode may incorrectly
 interpret everything past ‘;’ as format specifier:
 
      '(concat $1 ";")
 
 You can put an extra tailing ‘;’ to indicate that all the earlier
 instances of ‘;’ belong to the formula itself:
 
      '(concat $1 ";");

 3.5.4 Durations and time values
 -------------------------------
 
 If you want to compute time values use the ‘T’, ‘t’, or ‘U’ flag, either
 in Calc formulas or Elisp formulas:
 
      |  Task 1 |   Task 2 |    Total |
      |---------+----------+----------|
      |    2:12 |     1:47 | 03:59:00 |
      |    2:12 |     1:47 |    03:59 |
      | 3:02:20 | -2:07:00 |     0.92 |
      #+TBLFM: @2$3=$1+$2;T::@3$3=$1+$2;U::@4$3=$1+$2;t
 
    Input duration values must be of the form ‘HH:MM[:SS]’, where seconds
 are optional.  With the ‘T’ flag, computed durations are displayed as
 ‘HH:MM:SS’ (see the first formula above).  With the ‘U’ flag, seconds
 are omitted so that the result is only ‘HH:MM’ (see second formula
 above).  Zero-padding of the hours field depends upon the value of the
 variable ‘org-table-duration-hour-zero-padding’.
 
    With the ‘t’ flag, computed durations are displayed according to the
 value of the option ‘org-table-duration-custom-format’, which defaults
 to ‘hours’ and displays the result as a fraction of hours (see the third
 formula in the example above).
 
    Negative duration values can be manipulated as well, and integers are
 considered as seconds in addition and subtraction.

 3.5.5 Field and range formulas
 ------------------------------
 
 To assign a formula to a particular field, type it directly into the
 field, preceded by ‘:=’, for example ‘vsum(@II..III)’.  When you press
 ‘<TAB>’ or ‘<RET>’ or ‘C-c C-c’ with point still in the field, the
 formula is stored as the formula for this field, evaluated, and the
 current field is replaced with the result.
 
    Formulas are stored in a special ‘TBLFM’ keyword located directly
 below the table.  If you type the equation in the fourth field of the
 third data line in the table, the formula looks like ‘@3$4=$1+$2’.  When
 inserting/deleting/swapping column and rows with the appropriate
 commands, _absolute references_ (but not relative ones) in stored
 formulas are modified in order to still reference the same field.  To
 avoid this from happening, in particular in range references, anchor
 ranges at the table borders (using ‘@<’, ‘@>’, ‘$<’, ‘$>’), or at hlines
 using the ‘@I’ notation.  Automatic adaptation of field references does
 not happen if you edit the table structure with normal editing
 commands—you must fix the formulas yourself.
 
    Instead of typing an equation into the field, you may also use the
 following command
 
 ‘C-u C-c =’ (‘org-table-eval-formula’)
      Install a new formula for the current field.  The command prompts
      for a formula with default taken from the ‘TBLFM’ keyword, applies
      it to the current field, and stores it.
 
    The left-hand side of a formula can also be a special expression in
 order to assign the formula to a number of different fields.  There is
 no keyboard shortcut to enter such range formulas.  To add them, use the
 formula editor (see *note Editing and debugging formulas::) or edit the
 ‘TBLFM’ keyword directly.
 
 ‘$2=’
      Column formula, valid for the entire column.  This is so common
      that Org treats these formulas in a special way, see *note Column
      formulas::.
 
 ‘@3=’
      Row formula, applies to all fields in the specified row.  ‘@>=’
      means the last row.
 
 ‘@1$2..@4$3=’
      Range formula, applies to all fields in the given rectangular
      range.  This can also be used to assign a formula to some but not
      all fields in a row.
 
 ‘$NAME=’
      Named field, see *note Advanced features::.
 
 
 File: org.info,  Node: Column formulas,  Next: Lookup functions,  Prev: Field and range formulas,  Up: The Spreadsheet
 
 3.5.6 Column formulas
 ---------------------
 
 When you assign a formula to a simple column reference like ‘$3=’, the
 same formula is used in all fields of that column, with the following
 very convenient exceptions: (i) If the table contains horizontal
 separator hlines with rows above and below, everything before the first
 such hline is considered part of the table _header_ and is not modified
 by column formulas.  Therefore a header is mandatory when you use column
 formulas and want to add hlines to group rows, like for example to
 separate a total row at the bottom from the summand rows above.  (ii)
 Fields that already get a value from a field/range formula are left
 alone by column formulas.  These conditions make column formulas very
 easy to use.
 
    To assign a formula to a column, type it directly into any field in
 the column, preceded by an equal sign, like ‘=$1+$2’.  When you press
 ‘<TAB>’ or ‘<RET>’ or ‘C-c C-c’ with point still in the field, the
 formula is stored as the formula for the current column, evaluated and
 the current field replaced with the result.  If the field contains only
 ‘=’, the previously stored formula for this column is used.  For each
 column, Org only remembers the most recently used formula.  In the
 ‘TBLFM’ keyword, column formulas look like ‘$4=$1+$2’.  The left-hand
 side of a column formula can not be the name of column, it must be the
 numeric column reference or ‘$>’.
 
    Instead of typing an equation into the field, you may also use the
 following command:
 
 ‘C-c =’ (‘org-table-eval-formula’)
      Install a new formula for the current column and replace current
      field with the result of the formula.  The command prompts for a
      formula, with default taken from the ‘TBLFM’ keyword, applies it to
      the current field and stores it.  With a numeric prefix argument,
      e.g., ‘C-5 C-c =’, the command applies it to that many consecutive
      fields in the current column.

 3.5.7 Lookup functions
 ----------------------
 
 Org has three predefined Emacs Lisp functions for lookups in tables.
 
 ‘(org-lookup-first VAL S-LIST R-LIST &optional PREDICATE)’
      Searches for the first element S in list S-LIST for which
           (PREDICATE VAL S)
      is non-‘nil’; returns the value from the corresponding position in
      list R-LIST.  The default PREDICATE is ‘equal’.  Note that the
      parameters VAL and S are passed to PREDICATE in the same order as
      the corresponding parameters are in the call to ‘org-lookup-first’,
      where VAL precedes S-LIST.  If R-LIST is ‘nil’, the matching
      element S of S-LIST is returned.
 
 ‘(org-lookup-last VAL S-LIST R-LIST &optional PREDICATE)’
      Similar to ‘org-lookup-first’ above, but searches for the _last_
      element for which PREDICATE is non-‘nil’.
 
 ‘(org-lookup-all VAL S-LIST R-LIST &optional PREDICATE)’
      Similar to ‘org-lookup-first’, but searches for _all_ elements for
      which PREDICATE is non-‘nil’, and returns _all_ corresponding
      values.  This function can not be used by itself in a formula,
      because it returns a list of values.  However, powerful lookups can
      be built when this function is combined with other Emacs Lisp
      functions.
 
    If the ranges used in these functions contain empty fields, the ‘E’
 mode for the formula should usually be specified: otherwise empty fields
 are not included in S-LIST and/or R-LIST which can, for example, result
 in an incorrect mapping from an element of S-LIST to the corresponding
 element of R-LIST.
 
    These three functions can be used to implement associative arrays,
 count matching cells, rank results, group data, etc.  For practical
 examples see this tutorial on Worg
 (https://orgmode.org/worg/org-tutorials/org-lookups.html).

 3.5.8 Editing and debugging formulas
 ------------------------------------
 
 You can edit individual formulas in the minibuffer or directly in the
 field.  Org can also prepare a special buffer with all active formulas
 of a table.  When offering a formula for editing, Org converts
 references to the standard format (like ‘B3’ or ‘D&’) if possible.  If
 you prefer to only work with the internal format (like ‘@3$2’ or ‘$4’),
 configure the variable ‘org-table-use-standard-references’.
 
 ‘C-c =’ or ‘C-u C-c =’ (‘org-table-eval-formula’)
      Edit the formula associated with the current column/field in the
      minibuffer.  See *note Column formulas::, and *note Field and range
      formulas::.
 
 ‘C-u C-u C-c =’ (‘org-table-eval-formula’)
      Re-insert the active formula (either a field formula, or a column
      formula) into the current field, so that you can edit it directly
      in the field.  The advantage over editing in the minibuffer is that
      you can use the command ‘C-c ?’.
 
 ‘C-c ?’ (‘org-table-field-info’)
      While editing a formula in a table field, highlight the field(s)
      referenced by the reference at point position in the formula.
 
 ‘C-c }’ (‘org-table-toggle-coordinate-overlays’)
      Toggle the display of row and column numbers for a table, using
      overlays.  These are updated each time the table is aligned; you
      can force it with ‘C-c C-c’.
 
 ‘C-c {’ (‘org-table-toggle-formula-debugger’)
      Toggle the formula debugger on and off.  See below.
 
 ‘C-c '’ (‘org-table-edit-formulas’)
      Edit all formulas for the current table in a special buffer, where
      the formulas are displayed one per line.  If the current field has
      an active formula, point in the formula editor marks it.  While
      inside the special buffer, Org automatically highlights any field
      or range reference at point position.  You may edit, remove and add
      formulas, and use the following commands:
 
      ‘C-c C-c’ or ‘C-x C-s’ (‘org-table-fedit-finish’)
           Exit the formula editor and store the modified formulas.  With
           ‘C-u’ prefix, also apply the new formulas to the entire table.
 
      ‘C-c C-q’ (‘org-table-fedit-abort’)
           Exit the formula editor without installing changes.
 
      ‘C-c C-r’ (‘org-table-fedit-toggle-ref-type’)
           Toggle all references in the formula editor between standard
           (like ‘B3’) and internal (like ‘@3$2’).
 
      ‘<TAB>’ (‘org-table-fedit-lisp-indent’)
           Pretty-print or indent Lisp formula at point.  When in a line
           containing a Lisp formula, format the formula according to
           Emacs Lisp rules.  Another ‘<TAB>’ collapses the formula back
           again.  In the open formula, ‘<TAB>’ re-indents just like in
           Emacs Lisp mode.
 
      ‘M-<TAB>’ (‘lisp-complete-symbol’)
           Complete Lisp symbols, just like in Emacs Lisp mode.
 
      ‘S-<UP>’, ‘S-<DOWN>’, ‘S-<LEFT>’, ‘S-<RIGHT>’
           Shift the reference at point.  For example, if the reference
           is ‘B3’ and you press ‘S-<RIGHT>’, it becomes ‘C3’.  This also
           works for relative references and for hline references.
 
      ‘M-S-<UP>’ (‘org-table-fedit-line-up’)
           Move the test line for column formulas up in the Org buffer.
 
      ‘M-S-<DOWN>’ (‘org-table-fedit-line-down’)
           Move the test line for column formulas down in the Org buffer.
 
      ‘M-<UP>’ (‘org-table-fedit-scroll-up’)
           Scroll up the window displaying the table.
 
      ‘M-<DOWN>’ (‘org-table-fedit-scroll-down’)
           Scroll down the window displaying the table.
 
      ‘C-c }’
           Turn the coordinate grid in the table on and off.
 
    Making a table field blank does not remove the formula associated
 with the field, because that is stored in a different line—the ‘TBLFM’
 keyword line.  During the next recalculation, the field will be filled
 again.  To remove a formula from a field, you have to give an empty
 reply when prompted for the formula, or to edit the ‘TBLFM’ keyword.
 
    You may edit the ‘TBLFM’ keyword directly and re-apply the changed
 equations with ‘C-c C-c’ in that line or with the normal recalculation
 commands in the table.
 
 Using multiple ‘TBLFM’ lines
 ............................
 
 You may apply the formula temporarily.  This is useful when you want to
 switch the formula applied to the table.  Place multiple ‘TBLFM’
 keywords right after the table, and then press ‘C-c C-c’ on the formula
 to apply.  Here is an example:
 
      | x | y |
      |---+---|
      | 1 |   |
      | 2 |   |
      #+TBLFM: $2=$1*1
      #+TBLFM: $2=$1*2
 
 Pressing ‘C-c C-c’ in the line of ‘#+TBLFM: $2=$1*2’ yields:
 
      | x | y |
      |---+---|
      | 1 | 2 |
      | 2 | 4 |
      #+TBLFM: $2=$1*1
      #+TBLFM: $2=$1*2
 
 If you recalculate this table, with ‘C-u C-c *’, for example, you get
 the following result from applying only the first ‘TBLFM’ keyword.
 
      | x | y |
      |---+---|
      | 1 | 1 |
      | 2 | 2 |
      #+TBLFM: $2=$1*1
      #+TBLFM: $2=$1*2
 
 Debugging formulas
 ..................
 
 When the evaluation of a formula leads to an error, the field content
 becomes the string ‘#ERROR’.  If you want to see what is going on during
 variable substitution and calculation in order to find a bug, turn on
 formula debugging in the Tbl menu and repeat the calculation, for
 example by pressing ‘C-u C-u C-c = <RET>’ in a field.  Detailed
 information are displayed.

 3.5.9 Updating the table
 ------------------------
 
 Recalculation of a table is normally not automatic, but needs to be
 triggered by a command.  To make recalculation at least semi-automatic,
 see *note Advanced features::.
 
    In order to recalculate a line of a table or the entire table, use
 the following commands:
 
 ‘C-c *’ (‘org-table-recalculate’)
      Recalculate the current row by first applying the stored column
      formulas from left to right, and all field/range formulas in the
      current row.
 
 ‘C-u C-c *’ or ‘C-u C-c C-c’
      Recompute the entire table, line by line.  Any lines before the
      first hline are left alone, assuming that these are part of the
      table header.
 
 ‘C-u C-u C-c *’ or ‘C-u C-u C-c C-c’ (‘org-table-iterate’)
      Iterate the table by recomputing it until no further changes occur.
      This may be necessary if some computed fields use the value of
      other fields that are computed _later_ in the calculation sequence.
 
 ‘M-x org-table-recalculate-buffer-tables’
      Recompute all tables in the current buffer.
 
 ‘M-x org-table-iterate-buffer-tables’
      Iterate all tables in the current buffer, in order to converge
      table-to-table dependencies.
 
 
 File: org.info,  Node: Advanced features,  Prev: Updating the table,  Up: The Spreadsheet
 
 3.5.10 Advanced features
 ------------------------
 
 If you want the recalculation of fields to happen automatically, or if
 you want to be able to assign _names_(1) to fields and columns, you need
 to reserve the first column of the table for special marking characters.
 
 ‘C-#’ (‘org-table-rotate-recalc-marks’)
      Rotate the calculation mark in first column through the states ‘#’,
      ‘*’, ‘!’, ‘$’.  When there is an active region, change all marks in
      the region.
 
    Here is an example of a table that collects exam results of students
 and makes use of these features:
 
      |---+---------+--------+--------+--------+-------+------|
      |   | Student | Prob 1 | Prob 2 | Prob 3 | Total | Note |
      |---+---------+--------+--------+--------+-------+------|

      | ^ |         |        |        |        |    at |      |
      | $ | max=50  |        |        |        |       |      |
      |---+---------+--------+--------+--------+-------+------|
      #+TBLFM: $6=vsum($P1..$P3)::$7=10*$Tot/$max;%.1f::$at=vmean(@-II..@-I);%.1f
 
      Important: Please note that for these special tables, recalculating
      the table with ‘C-u C-c *’ only affects rows that are marked ‘#’ or
      ‘*’, and fields that have a formula assigned to the field itself.
      The column formulas are not applied in rows with empty first field.
 
    The marking characters have the following meaning:
 
 ‘!’
      The fields in this line define names for the columns, so that you
      may refer to a column as ‘$Tot’ instead of ‘$6’.
 
 ‘^’
      This row defines names for the fields _above_ the row.  With such a
      definition, any formula in the table may use ‘$m1’ to refer to the
      value ‘10’.  Also, if you assign a formula to a names field, it is
      stored as ‘$name = ...’.
 
 ‘_’
      Similar to ‘^’, but defines names for the fields in the row
      _below_.
 
 ‘$’
      Fields in this row can define _parameters_ for formulas.  For
      example, if a field in a ‘$’ row contains ‘max=50’, then formulas
      in this table can refer to the value 50 using ‘$max’.  Parameters
      work exactly like constants, only that they can be defined on a
      per-table basis.
 
 ‘#’
      Fields in this row are automatically recalculated when pressing
      ‘<TAB>’ or ‘<RET>’ or ‘S-<TAB>’ in this row.  Also, this row is
      selected for a global recalculation with ‘C-u C-c *’.  Unmarked
      lines are left alone by this command.
 
 ‘*’
      Selects this line for global recalculation with ‘C-u C-c *’, but
      not for automatic recalculation.  Use this when automatic
      recalculation slows down editing too much.
 
 ‘/’
      Do not export this line.  Useful for lines that contain the
      narrowing ‘<N>’ markers or column group markers.
 
    Finally, just to whet your appetite for what can be done with the
 fantastic Calc package, here is a table that computes the Taylor series
 of degree n at location x for a couple of functions.

 3.6 Org Plot
 ============
 
 Org Plot can produce graphs of information stored in Org tables, either
 graphically or in ASCII art.
 
 Graphical plots using Gnuplot
 -----------------------------
 
 Org Plot can produce 2D and 3D graphs of information stored in Org
 tables using Gnuplot (https://www.gnuplot.info/) and Gnuplot mode
 (http://cars9.uchicago.edu/~ravel/software/gnuplot-mode.html).  To see
 this in action, ensure that you have both Gnuplot and Gnuplot mode
 installed on your system, then call ‘C-c " g’ or ‘M-x org-plot/gnuplot’
 on the following table.
 
      #+PLOT: title:"Citas" ind:1 deps:(3) type:2d with:histograms set:"yrange [0:]"
      | Sede      | Max cites | H-index |
      |-----------+-----------+---------|
      | Chile     |    257.72 |   21.39 |
      | Leeds     |    165.77 |   19.68 |
      | Sao Paolo |     71.00 |   11.50 |
      | Stockholm |    134.19 |   14.33 |
      | Morelia   |    257.56 |   17.67 |
 
    Org Plot supports a range of plot types, and provides the ability to
 add more.  For example, a radar plot can be generated like so:
      #+PLOT: title:"An evaluation of plaintext document formats" transpose:yes type:radar min:0 max:4

    Notice that Org Plot is smart enough to apply the table’s headers as
 labels.  Further control over the labels, type, content, and appearance
 of plots can be exercised through the ‘PLOT’ keyword preceding a table.
 See below for a complete list of Org Plot options.  For more information
 and examples see the Org Plot tutorial
 (https://orgmode.org/worg/org-tutorials/org-plot.html).
 
 Plot options
 ............
 
 ‘set’
      Specify any Gnuplot option to be set when graphing.
 
 ‘title’
      Specify the title of the plot.
 
 ‘ind’
      Specify which column of the table to use as the ‘x’ axis.
 
 ‘timeind’
      Specify which column of the table to use as the ‘x’ axis as a time
      value.
 
 ‘deps’
      Specify the columns to graph as a Lisp style list, surrounded by
      parentheses and separated by spaces for example ‘dep:(3 4)’ to
      graph the third and fourth columns.  Defaults to graphing all other
      columns aside from the ‘ind’ column.
 
 ‘transpose’
      When ‘y’, ‘yes’, or ‘t’ attempt to transpose the table data before
      plotting.  Also recognizes the shorthand option ‘trans’.
 
 ‘type’
      Specify the type of the plot, by default one of ‘2d’, ‘3d’,
      ‘radar’, or ‘grid’.  Available types can be customized with
      ‘org-plot/preset-plot-types’.
 
 ‘with’
      Specify a ‘with’ option to be inserted for every column being
      plotted, e.g., ‘lines’, ‘points’, ‘boxes’, ‘impulses’.  Defaults to
      ‘lines’.
 
 ‘file’
      If you want to plot to a file, specify
      ‘"path/to/desired/output-file"’.
 
 ‘labels’
      List of labels to be used for the ‘deps’.  Defaults to the column
      headers if they exist.
 
 ‘line’
      Specify an entire line to be inserted in the Gnuplot script.
 
 ‘map’
      When plotting ‘3d’ or ‘grid’ types, set this to ‘t’ to graph a flat
      mapping rather than a ‘3d’ slope.
 
 ‘min’
      Provides a minimum axis value that may be used by a plot type.
      Implicitly assumes the ‘y’ axis is being referred to.  Can
      explicitly provide a value for a either the ‘x’ or ‘y’ axis with
      ‘xmin’ and ‘ymin’.
 
 ‘max’
      Provides a maximum axis value that may be used by a plot type.
      Implicitly assumes the ‘y’ axis is being referred to.  Can
      explicitly provide a value for a either the ‘x’ or ‘y’ axis with
      ‘xmax’ and ‘ymax’.
 
 ‘ticks’
      Provides a desired number of axis ticks to display, that may be
      used by a plot type.  If none is given a plot type that requires
      ticks will use ‘org--plot/sensible-tick-num’ to try to determine a
      good value.
 
 ‘timefmt’
      Specify format of Org mode timestamps as they will be parsed by
      Gnuplot.  Defaults to ‘%Y-%m-%d-%H:%M:%S’.
 
 ‘script’
      If you want total control, you can specify a script file—place the
      file name between double-quotes—which will be used to plot.  Before
      plotting, every instance of ‘$datafile’ in the specified script
      will be replaced with the path to the generated data file.  Note:
      even if you set this option, you may still want to specify the plot
      type, as that can impact the content of the data file.
 
 ASCII bar plots
 ---------------
 
 While point is on a column, typing ‘C-c " a’ or ‘M-x orgtbl-ascii-plot’
 create a new column containing an ASCII-art bars plot.  The plot is
 implemented through a regular column formula.  When the source column
 changes, the bar plot may be updated by refreshing the table, for
 example typing ‘C-u C-c *’.

    The formula is an Elisp call.
 
  -- Function: orgtbl-ascii-draw value min max &optional width
      Draw an ASCII bar in a table.
 
      VALUE is the value to plot.
 
      MIN is the value displayed as an empty bar.  MAX is the value
      filling all the WIDTH.  Sources values outside this range are
      displayed as ‘too small’ or ‘too large’.
 
      WIDTH is the number of characters of the bar plot.  It defaults to
      ‘12’.

 File: org.info,  Node: Link Format,  Next: Internal Links,  Up: Hyperlinks
 
 4.1 Link Format
 ===============
 
 Org recognizes plain URIs, possibly wrapped within angle brackets(1),
 and activate them as clickable links.
 
    The general link format, however, looks like this:
 
      [[LINK][DESCRIPTION]]
 
 or alternatively
 
      [[LINK]]
 
    Some ‘\’, ‘[’ and ‘]’ characters in the LINK part need to be
 “escaped”, i.e., preceded by another ‘\’ character.  More specifically,
 the following characters, and only them, must be escaped:
 
   1. all ‘[’ and ‘]’ characters,
   2. every ‘\’ character preceding either ‘]’ or ‘[’,
   3. every ‘\’ character at the end of the link.
 
    Functions inserting links (see *note Handling Links::) properly
 escape ambiguous characters.  You only need to bother about the rules
 above when inserting directly, or yanking, a URI within square brackets.
 When in doubt, you may use the function ‘org-link-escape’, which turns a
 link string into its escaped form.
 
    Once a link in the buffer is complete, with all brackets present, Org
 changes the display so that ‘DESCRIPTION’ is displayed instead of
 ‘[[LINK][DESCRIPTION]]’ and ‘LINK’ is displayed instead of ‘[[LINK]]’.
 Links are highlighted in the ‘org-link’ face, which, by default, is an
 underlined face.
 
    You can directly edit the visible part of a link.  This can be either
 the LINK part, if there is no description, or the DESCRIPTION part
 otherwise.  To also edit the invisible LINK part, use ‘C-c C-l’ with
 point on the link (see *note Handling Links::).
 
    If you place point at the beginning or just behind the end of the
 displayed text and press ‘<BS>’, you remove the—invisible—bracket at
 that location(2).  This makes the link incomplete and the internals are
 again displayed as plain text.  Inserting the missing bracket hides the
 link internals again.  To show the internal structure of all links, use
 the menu: Org → Hyperlinks → Literal links, customize
 ‘org-link-descriptive’, or use ‘literallinks’ *note startup option:
 In-buffer Settings.
 
    ---------- Footnotes ----------
 
    (1) Plain URIs are recognized only for a well-defined set of schemes.
 See *note External Links::.  Unlike URI syntax, they cannot contain
 parenthesis or white spaces, either.  URIs within angle brackets have no
 such limitation.
 
    (2) More accurately, the precise behavior depends on how point
 arrived there—see *note Invisible Text: (elisp)Invisible Text.
 
 
 File: org.info,  Node: Internal Links,  Next: Radio Targets,  Prev: Link Format,  Up: Hyperlinks
 
 4.2 Internal Links
 ==================
 
 A link that does not look like a URL—i.e., does not start with a known
 scheme or a file name—refers to the current document.  You can follow it
 with ‘C-c C-o’ when point is on the link, or with a mouse click (see
 *note Handling Links::).
 
    Org provides several refinements to internal navigation within a
 document.  Most notably, a construct like ‘[[#my-custom-id]]’
 specifically targets the entry with the ‘CUSTOM_ID’ property set to
 ‘my-custom-id’.  Also, an internal link looking like ‘[[*Some section]]’
 points to a headline with the name ‘Some section’(1).
 
    When the link does not belong to any of the cases above, Org looks
 for a _dedicated target_: the same string in double angular brackets,
 like ‘<<My Target>>’.
 
    If no dedicated target exists, the link tries to match the exact name
 of an element within the buffer.  Naming is done, unsurprisingly, with
 the ‘NAME’ keyword, which has to be put in the line before the element
 it refers to, as in the following example
 
      #+NAME: My Target
      | a  | table      |
      |----+------------|
      | of | four cells |
 
    Ultimately, if none of the above succeeds, Org searches for a
 headline that is exactly the link text but may also include a TODO
 keyword and tags, or initiates a plain text search, according to the
 value of ‘org-link-search-must-match-exact-headline’.
 
    Note that you must make sure custom IDs, dedicated targets, and names
 are unique throughout the document.  Org provides a linter to assist you
 in the process, if needed.  See *note Org Syntax::.
 
    During export, internal links are used to mark objects and assign
 them a number.  Marked objects are then referenced by links pointing to
 them.  In particular, links without a description appear as the number
 assigned to the marked object(2).  In the following excerpt from an Org
 buffer
 
      1. one item
      2. <<target>>another item
      Here we refer to item [[target]].
 
 The last sentence will appear as ‘Here we refer to item 2’ when
 exported.
 
    In non-Org files, the search looks for the words in the link text.
 In the above example the search would be for ‘target’.
 
    Following a link pushes a mark onto Org’s own mark ring.  You can
 return to the previous position with ‘C-c &’.  Using this command
 several times in direct succession goes back to positions recorded
 earlier.
 
    ---------- Footnotes ----------
 
    (1) To insert a link targeting a headline, in-buffer completion can
 be used.  Just type a star followed by a few optional letters into the
 buffer and press ‘M-<TAB>’.  All headlines in the current buffer are
 offered as completions.
 
    (2) When targeting a ‘NAME’ keyword, the ‘CAPTION’ keyword is
 mandatory in order to get proper numbering (see *note Captions::).
 
 
 File: org.info,  Node: Radio Targets,  Next: External Links,  Prev: Internal Links,  Up: Hyperlinks
 
 4.3 Radio Targets
 =================
 
 Org can automatically turn any occurrences of certain target names in
 normal text into a link.  So without explicitly creating a link, the
 text connects to the target radioing its position.  Radio targets are
 enclosed by triple angular brackets.  For example, a target ‘<<<My
 Target>>>’ causes each occurrence of ‘my target’ in normal text to
 become activated as a link.  The Org file is scanned automatically for
 radio targets only when the file is first loaded into Emacs.  To update
 the target list during editing, press ‘C-c C-c’ with point on or at a
 target.
 
 
 File: org.info,  Node: External Links,  Next: Handling Links,  Prev: Radio Targets,  Up: Hyperlinks
 
 4.4 External Links
 ==================
 
 Org supports links to files, websites, Usenet and email messages, BBDB
 database entries and links to both IRC conversations and their logs.
 External links are URL-like locators.  They start with a short
 identifying string followed by a colon.  There can be no space after the
 colon.
 
    Here is the full set of built-in link types:
 
 ‘file’
      File links.  File name may be remote, absolute, or relative.
 
      As a special case, “file” prefix may be omitted if the file name is
      complete, e.g., it starts with ‘./’, or ‘/’.
 
 ‘attachment’
      Same as file links but for files and folders attached to the
      current node (see *note Attachments::).  Attachment links are
      intended to behave exactly as file links but for files relative to
      the attachment directory.
 
 ‘bbdb’
      Link to a BBDB record, with possible regexp completion.
 
 ‘docview’
      Link to a document opened with DocView mode.  You may specify a
      page number.
 
 ‘doi’
      Link to an electronic resource, through its handle.
 
 ‘elisp’
      Execute an Elisp command upon activation.
 
 ‘gnus’, ‘rmail’, ‘mhe’
      Link to messages or folders from a given Emacs MUA.
 
 ‘help’
      Display documentation of a symbol in ‘*Help*’ buffer.
 
 ‘http’, ‘https’
      Web links.
 
 ‘id’
      Link to a specific headline by its ID property, in an Org file.
 
 ‘info’
      Link to an Info manual, or to a specific node.
 
 ‘irc’
      Link to an IRC channel.
 
 ‘mailto’
      Link to message composition.
 
 ‘news’
      Usenet links.
 
 ‘shell’
      Execute a shell command upon activation.
 
    For ‘file:’ and ‘id:’ links, you can additionally specify a line
 number, or a text search string, separated by ‘::’.  In Org files, you
 may link to a headline name, a custom ID, or a code reference instead.
 
    The following table illustrates the link types above, along with
 their options:

              ‘elisp:org-agenda’ (interactive Elisp command)
 
    On top of these built-in link types, additional ones are available
 through the ‘org-contrib’ repository (see *note Installation::).  For
 example, these links to VM or Wanderlust messages are available when you
 load the corresponding libraries from the ‘org-contrib’ repository:
 
 ‘vm:folder’                              VM folder link
 ‘vm:folder#id’                           VM message link
 ‘vm://myself@some.where.org/folder#id’   VM on remote machine
 ‘vm-imap:account:folder’                 VM IMAP folder link
 ‘vm-imap:account:folder#id’              VM IMAP message link
 ‘wl:folder’                              Wanderlust folder link
 ‘wl:folder#id’                           Wanderlust message link
 
    For information on customizing Org to add new link types, see *note
 Adding Hyperlink Types::.
 
    A link should be enclosed in double brackets and may contain
 descriptive text to be displayed instead of the URL (see *note Link
 Format::), for example:
 
      [[https://www.gnu.org/software/emacs/][GNU Emacs]]
 
    If the description is a file name or URL that points to an image,
 HTML export (see *note HTML Export::) inlines the image as a clickable
 button.  If there is no description at all and the link points to an
 image, that image is inlined into the exported HTML file.
 
    Org also recognizes external links amid normal text and activates
 them as links.  If spaces must be part of the link (for example in
 ‘bbdb:R.*Stallman’), or if you need to remove ambiguities about the end
 of the link, enclose the link in square or angular brackets.
 
    ---------- Footnotes ----------
 
    (1) The actual behavior of the search depends on the value of the
 variable ‘org-link-search-must-match-exact-headline’.  If its value is
 ‘nil’, then a fuzzy text search is done.  If it is ‘t’, then only the
 exact headline is matched, ignoring spaces and statistic cookies.  If
 the value is ‘query-to-create’, then an exact headline is searched; if
 it is not found, then the user is queried to create it.

 4.5 Handling Links
 ==================
 
 Org provides methods to create a link in the correct syntax, to insert
 it into an Org file, and to follow the link.
 
    The main function is ‘org-store-link’, called with ‘M-x
 org-store-link’.  Because of its importance, we suggest to bind it to a
 widely available key (see *note Activation::).  It stores a link to the
 current location.  The link is stored for later insertion into an Org
 buffer—see below.  The kind of link that is created depends on the
 current buffer:
 
 _Org mode buffers_
      For Org files, if there is a ‘<<target>>’ at point, the link points
      to the target.  If there is a named block (using ‘#+name:’) at
      point, the link points to that name.  Otherwise it points to the
      current headline, which is also the description.
 
      If the headline has a ‘CUSTOM_ID’ property, store a link to this
      custom ID.  In addition or alternatively, depending on the value of
      ‘org-id-link-to-org-use-id’, create and/or use a globally unique
      ‘ID’ property for the link(1).  So using this command in Org
      buffers potentially creates two links: a human-readable link from
      the custom ID, and one that is globally unique and works even if
      the entry is moved from file to file.  The ‘ID’ property can be
      either a UUID (default) or a timestamp, depending on
      ‘org-id-method’.  Later, when inserting the link, you need to
      decide which one to use.
 
      When ‘org-id-link-consider-parent-id’ is ‘t’(2), parent ‘ID’
      properties are considered.  This allows linking to specific
      targets, named blocks, or headlines (which may not have a globally
      unique ‘ID’ themselves) within the context of a parent headline or
      file which does.
 
      For example, given this org file:
 
           * Parent
           :PROPERTIES:
           :ID: abc
           :END:
           ** Child 1
           ** Child 2
 
      Storing a link with point at “Child 1” will produce a link
      ‘<id:abc::*Child 1>’, which precisely links to the “Child 1”
      headline even though it does not have its own ID.
 
 _Email/News clients: VM, Rmail, Wanderlust, MH-E, Gnus_
      Pretty much all Emacs mail clients are supported.  The link points
      to the current article, or, in some Gnus buffers, to the group.
      The description is constructed according to the variable
      ‘org-link-email-description-format’.  By default, it refers to the
      addressee and the subject.
 
 _Web browsers: W3M and EWW_
      Here the link is the current URL, with the page title as the
      description.
 
 _Contacts: BBDB_
      Links created in a BBDB buffer point to the current entry.
 
 _Chat: IRC_
      For IRC links, if the variable ‘org-irc-link-to-logs’ is non-‘nil’,
      create a ‘file’ style link to the relevant point in the logs for
      the current conversation.  Otherwise store an ‘irc’ style link to
      the user/channel/server under the point.
 
 _Other files_
      For any other file, the link points to the file, with a search
      string (see *note Search Options::) pointing to the contents of the
      current line.  If there is an active region, the selected words
      form the basis of the search string.  You can write custom Lisp
      functions to select the search string and perform the search for
      particular file types (see *note Custom Searches::).
 
      You can also define dedicated links to other files.  See *note
      Adding Hyperlink Types::.
 
 _Agenda view_
      When point is in an agenda view, the created link points to the
      entry referenced by the current line.
 
    From an Org buffer, the following commands create, navigate or, more
 generally, act on links.
 
 ‘C-c C-l’ (‘org-insert-link’)
      Insert a link(3).  This prompts for a link to be inserted into the
      buffer.  You can just type a link, using text for an internal link,
      or one of the link type prefixes mentioned in the examples above.
      The link is inserted into the buffer, along with a descriptive
      text(4).  If some text was selected at this time, it becomes the
      default description.
 
      _Inserting stored links_
           All links stored during the current session are part of the
           history for this prompt, so you can access them with ‘<UP>’
           and ‘<DOWN>’ (or ‘M-p’, ‘M-n’).
 
      _Completion support_
           Completion with ‘<TAB>’ helps you to insert valid link
           prefixes like ‘http’ or ‘ftp’, including the prefixes defined
           through link abbreviations (see *note Link Abbreviations::).
           If you press ‘<RET>’ after inserting only the prefix, Org
           offers specific completion support for some link types(5).
           For example, if you type ‘f i l e <RET>’—alternative access:
           ‘C-u C-c C-l’, see below—Org offers file name completion, and
           after ‘b b d b <RET>’ you can complete contact names.
 
 ‘C-u C-c C-l’
      When ‘C-c C-l’ is called with a ‘C-u’ prefix argument, insert a
      link to a file.  You may use file name completion to select the
      name of the file.  The path to the file is inserted relative to the
      directory of the current Org file, if the linked file is in the
      current directory or in a sub-directory of it, or if the path is
      written relative to the current directory using ‘../’.  Otherwise
      an absolute path is used, if possible with ‘~/’ for your home
      directory.  You can force an absolute path with two ‘C-u’ prefixes.
 
 ‘C-c C-l’ (with point on existing link)
      When point is on an existing link, ‘C-c C-l’ allows you to edit the
      link and description parts of the link.
 
 ‘C-c C-o’ (‘org-open-at-point’)
      Open link at point.  This launches a web browser for URL (using
      ‘browse-url-at-point’), run VM/MH-E/Wanderlust/Rmail/Gnus/BBDB for
      the corresponding links, and execute the command in a shell link.
      When point is on an internal link, this command runs the
      corresponding search.  When point is on the tags part of a
      headline, it creates the corresponding tags view (see *note
      Matching tags and properties::).  If point is on a timestamp, it
      compiles the agenda for that date.  Furthermore, it visits text and
      remote files in ‘file’ links with Emacs and select a suitable
      application for local non-text files.  Classification of files is
      based on file extension only.  See option ‘org-file-apps’.  If you
      want to override the default application and visit the file with
      Emacs, use a ‘C-u’ prefix.  If you want to avoid opening in Emacs,
      use a ‘C-u C-u’ prefix.
 
      If point is on a headline, but not on a link, offer all links in
      the headline and entry text.  If you want to setup the frame
      configuration for following links, customize
      ‘org-link-frame-setup’.
 
 ‘<RET>’
      When ‘org-return-follows-link’ is set, ‘<RET>’ also follows the
      link at point.
 
 ‘mouse-2’ or ‘mouse-1’
      On links, ‘mouse-1’ and ‘mouse-2’ opens the link just as ‘C-c C-o’
      does.
 
 ‘mouse-3’
      Like ‘mouse-2’, but force file links to be opened with Emacs, and
      internal links to be displayed in another window(6).
 
 ‘C-c %’ (‘org-mark-ring-push’)
      Push the current position onto the Org mark ring, to be able to
      return easily.  Commands following an internal link do this
      automatically.
 
 ‘C-c &’ (‘org-mark-ring-goto’)
      Jump back to a recorded position.  A position is recorded by the
      commands following internal links, and by ‘C-c %’.  Using this
      command several times in direct succession moves through a ring of
      previously recorded positions.
 
 ‘C-c C-x C-n’ (‘org-next-link’)
 ‘C-c C-x C-p’ (‘org-previous-link’)
      Move forward/backward to the next link in the buffer.  At the limit
      of the buffer, the search fails once, and then wraps around.  The
      key bindings for this are really too long; you might want to bind
      this also to ‘M-n’ and ‘M-p’.
 
           (with-eval-after-load 'org
             (define-key org-mode-map (kbd "M-n") #'org-next-link)
             (define-key org-mode-map (kbd "M-p") #'org-previous-link))
 
    ---------- Footnotes ----------
 
    (1) The Org Id library must first be loaded, either through
 ‘org-customize’, by enabling ‘id’ in ‘org-modules’, or by adding
 ‘(require 'org-id)’ in your Emacs init file.
 
    (2) Also, ‘org-link-context-for-files’ and ‘org-id-link-use-context’
 should be both enabled (which they are, by default).
 
    (3) Note that you do not have to use this command to insert a link.
 Links in Org are plain text, and you can type or paste them straight
 into the buffer.  By using this command, the links are automatically
 enclosed in double brackets, and you will be asked for the optional
 descriptive text.
 
    (4) After insertion of a stored link, the link will be removed from
 the list of stored links.  To keep it in the list for later use, use a
 triple ‘C-u’ prefix argument to ‘C-c C-l’, or configure the option
 ‘org-link-keep-stored-after-insertion’.
 
    (5) This works if a function has been defined in the ‘:complete’
 property of a link in ‘org-link-parameters’.
 
    (6) See the variable ‘org-link-use-indirect-buffer-for-internals’.

 4.6 Using Links Outside Org
 ===========================
 
 You can insert and follow links that have Org syntax not only in Org,
 but in any Emacs buffer.  For this, Org provides two functions:
 ‘org-insert-link-global’ and ‘org-open-at-point-global’.
 
    You might want to bind them to globally available keys.  See *note
 Activation:: for some advice.
 
 
 File: org.info,  Node: Link Abbreviations,  Next: Search Options,  Prev: Using Links Outside Org,  Up: Hyperlinks
 
 4.7 Link Abbreviations
 ======================
 
 Long URL can be cumbersome to type, and often many similar links are
 needed in a document.  For this you can use link abbreviations.  An
 abbreviated link looks like this
 
      [[linkword:tag][description]]
 
 where the tag is optional.  The _linkword_ must be a word, starting with
 a letter, followed by letters, numbers, ‘-’, and ‘_’.  Abbreviations are
 resolved according to the information in the variable
 ‘org-link-abbrev-alist’ that relates the linkwords to replacement text.
 Here is an example:
 
      (setq org-link-abbrev-alist
            '(("bugzilla"        . "https://10.1.2.9/bugzilla/show_bug.cgi?id=")
              ("Nu Html Checker" . "https://validator.w3.org/nu/?doc=%h")
              ("duckduckgo"      . "https://duckduckgo.com/?q=%s")
              ("omap"            . "https://nominatim.openstreetmap.org/search?q=%s&polygon=1")
              ("ads"             . "https://ui.adsabs.harvard.edu/search/q=%20author%3A\"%s\"")))
 
    If the replacement text contains the string ‘%s’, it is replaced with
 the tag.  Using ‘%h’ instead of ‘%s’ percent-encodes the tag (see the
 example above, where we need to encode the URL parameter).  Using
 ‘%(my-function)’ passes the tag to a custom Lisp function, and replace
 it by the resulting string.
 
    If the replacement text do not contain any specifier, it is simply
 appended to the string in order to create the link.
 
    Instead of a string, you may also specify a Lisp function to create
 the link.  Such a function will be called with the tag as the only
 argument.
 
    With the above setting, you could link to a specific bug with
 ‘[[bugzilla:129]]’, search the web for ‘OrgMode’ with
 ‘[[duckduckgo:OrgMode]]’, show the map location of the Free Software
 Foundation ‘[[omap:31 Milk Street, Boston]]’ or of Carsten’s office
 ‘[[omap:Science Park 904, Amsterdam, The Netherlands]]’ and find out
 what the Org author is doing besides Emacs hacking with
 ‘[[ads:Dominik,C]]’.
 
    If you need special abbreviations just for a single Org buffer, you
 can define them in the file with
 
      #+LINK: bugzilla  https://10.1.2.9/bugzilla/show_bug.cgi?id=
      #+LINK: duckduckgo https://duckduckgo.com/?q=%s
      #+LINK: "Nu Html Checker" https://validator.w3.org/nu/?doc=%h
 
    The abbreviations containing spaces must be quoted.
 
    In-buffer completion (see *note Completion::) can be used after ‘[’
 to complete link abbreviations.  You may also define a Lisp function
 that implements special (e.g., completion) support for inserting such a
 link with ‘C-c C-l’.  Such a function should not accept any arguments,
 and should return the full link with a prefix.  You can set the link
 completion function like this:
 
      (org-link-set-parameter "type" :complete #'some-completion-function)
 
 
 File: org.info,  Node: Search Options,  Next: Custom Searches,  Prev: Link Abbreviations,  Up: Hyperlinks
 
 4.8 Search Options in File Links
 ================================
 
 File links can contain additional information to make Emacs jump to a
 particular location in the file when following a link.  This can be a
 line number or a search option after a double colon(1).  For example,
 when the command ‘org-store-link’ creates a link (see *note Handling
 Links::) to a file, it encodes the words in the current line as a search
 string that can be used to find this line back later when following the
 link with ‘C-c C-o’.
 
    Note that all search options apply for Attachment and ID links in the
 same way that they apply for File links.
 
    Here is the syntax of the different ways to attach a search to a file
 link, together with explanations for each:
 
      [[file:~/code/main.c::255]]
      [[file:~/xx.org::My Target]]
      [[file:~/xx.org::*My Target]]
      [[file:~/xx.org::#my-custom-id]]
      [[file:~/xx.org::/regexp/]]
      [[attachment:main.c::255]]
 
 ‘255’
      Jump to line 255.
 
 ‘My Target’
      Search for a link target ‘<<My Target>>’, or do a text search for
      ‘my target’, similar to the search in internal links, see *note
      Internal Links::.  In HTML export (see *note HTML Export::), such a
      file link becomes a HTML reference to the corresponding named
      anchor in the linked file.
 
 ‘*My Target’
      In an Org file, restrict search to headlines.
 
 ‘#my-custom-id’
      Link to a heading with a ‘CUSTOM_ID’ property
 
 ‘/REGEXP/’
      Do a regular expression search for REGEXP (see *note Regular
      Expressions::).  This uses the Emacs command ‘occur’ to list all
      matches in a separate window.  If the target file is in Org mode,
      ‘org-occur’ is used to create a sparse tree with the matches.
 
    As a degenerate case, a file link with an empty file name can be used
 to search the current file.  For example, ‘[[file:::find me]]’ does a
 search for ‘find me’ in the current file, just as ‘[[find me]]’ would.
 
    ---------- Footnotes ----------
 
    (1) For backward compatibility, line numbers can also follow a single
 colon.
 
 
 File: org.info,  Node: Custom Searches,  Prev: Search Options,  Up: Hyperlinks
 
 4.9 Custom Searches
 ===================
 
 The default mechanism for creating search strings and for doing the
 actual search related to a file link may not work correctly in all
 cases.  For example, BibTeX database files have many entries like
 ‘year="1993"’ which would not result in good search strings, because the
 only unique identification for a BibTeX entry is the citation key.
 
    If you come across such a problem, you can write custom functions to
 set the right search string for a particular file type, and to do the
 search for the string in the file.  Using ‘add-hook’, these functions
 need to be added to the hook variables
 ‘org-create-file-search-functions’ and
 ‘org-execute-file-search-functions’.  See the docstring for these
 variables for more information.  Org actually uses this mechanism for
 BibTeX database files, and you can use the corresponding code as an
 implementation example.  See the file ‘ol-bibtex.el’.
 
 
 File: org.info,  Node: TODO Items,  Next: Tags,  Prev: Hyperlinks,  Up: Top
 
 5 TODO Items
 ************
 
 Org mode does not maintain TODO lists as separate documents(1).
 Instead, TODO items are an integral part of the notes file, because TODO
 items usually come up while taking notes!  With Org mode, simply mark
 any entry in a tree as being a TODO item.  In this way, information is
 not duplicated, and the entire context from which the TODO item emerged
 is always present.
 
    Of course, this technique for managing TODO items scatters them
 throughout your notes file.  Org mode compensates for this by providing
 methods to give you an overview of all the things that you have to do.
 
 * Menu:
 
 * TODO Basics::                  Marking and displaying TODO entries.
 * TODO Extensions::              Workflow and assignments.
 * Progress Logging::             Dates and notes for progress.
 * Priorities::                   Some things are more important than others.
 * Breaking Down Tasks::          Splitting a task into manageable pieces.
 * Checkboxes::                   Tick-off lists.
 
    ---------- Footnotes ----------
 
    (1) Of course, you can make a document that contains only long lists
 of TODO items, but this is not required.
 
 
 File: org.info,  Node: TODO Basics,  Next: TODO Extensions,  Up: TODO Items
 
 5.1 Basic TODO Functionality
 ============================
 
 Any headline becomes a TODO item when it starts with the word ‘TODO’,
 for example:
 
      *** TODO Write letter to Sam Fortune
 
    The most important commands to work with TODO entries are:
 
 ‘C-c C-t’ (‘org-todo’)
      Rotate the TODO state of the current item among
 
           ,-> (unmarked) -> TODO -> DONE --.
           '--------------------------------'
 
      If TODO keywords have fast access keys (see *note Fast access to
      TODO states::), prompt for a TODO keyword through the fast
      selection interface; this is the default behavior when
      ‘org-use-fast-todo-selection’ is non-‘nil’.
 
      The same state changing can also be done “remotely” from the agenda
      buffer with the ‘t’ command key (see *note Agenda Commands::).
 
 ‘S-<RIGHT>’ ‘S-<LEFT>’
      Select the following/preceding TODO state, similar to cycling.
      Useful mostly if more than two TODO states are possible (see *note
      TODO Extensions::).  See also *note Conflicts::, for a discussion
      of the interaction with shift-selection.  See also the variable
      ‘org-treat-S-cursor-todo-selection-as-state-change’.
 
 ‘C-c / t’ (‘org-show-todo-tree’)
      View TODO items in a _sparse tree_ (see *note Sparse Trees::).
      Folds the entire buffer, but shows all TODO items—with not-DONE
      state—and the headings hierarchy above them.  With a prefix
      argument, or by using ‘C-c / T’, search for a specific TODO.  You
      are prompted for the keyword, and you can also give a list of
      keywords like ‘KWD1|KWD2|...’ to list entries that match any one of
      these keywords.  With a numeric prefix argument N, show the tree
      for the Nth keyword in the variable ‘org-todo-keywords’.  With two
      prefix arguments, find all TODO states, both un-done and done.
 
 ‘M-x org-agenda t’ (‘org-todo-list’)
      Show the global TODO list.  Collects the TODO items (with not-DONE
      states) from all agenda files (see *note Agenda Views::) into a
      single buffer.  The new buffer is in Org Agenda mode, which
      provides commands to examine and manipulate the TODO entries from
      the new buffer (see *note Agenda Commands::).  See *note Global
      TODO list::, for more information.
 
 ‘S-M-<RET>’ (‘org-insert-todo-heading’)
      Insert a new TODO entry below the current one.
 
    Changing a TODO state can also trigger tag changes.  See the
 docstring of the option ‘org-todo-state-tags-triggers’ for details.
 
 
 File: org.info,  Node: TODO Extensions,  Next: Progress Logging,  Prev: TODO Basics,  Up: TODO Items
 
 5.2 Extended Use of TODO Keywords
 =================================
 
 By default, marked TODO entries have one of only two states: TODO and
 DONE.  Org mode allows you to classify TODO items in more complex ways
 with _TODO keywords_ (stored in ‘org-todo-keywords’).  With special
 setup, the TODO keyword system can work differently in different files.
 
    Note that _tags_ are another way to classify headlines in general and
 TODO items in particular (see *note Tags::).
 
 * Menu:
 
 * Workflow states::              From TODO to DONE in steps.
 * TODO types::                   I do this, Fred does the rest.
 * Multiple sets in one file::    Mixing it all, still finding your way.
 * Fast access to TODO states::   Single letter selection of state.
 * Per-file keywords::            Different files, different requirements.
 * Faces for TODO keywords::      Highlighting states.
 * TODO dependencies::            When one task needs to wait for others.
 
 
 File: org.info,  Node: Workflow states,  Next: TODO types,  Up: TODO Extensions
 
 5.2.1 TODO keywords as workflow states
 --------------------------------------
 
 You can use TODO keywords to indicate different, possibly _sequential_
 states in the process of working on an item, for example(1):
 
      (setq org-todo-keywords
            '((sequence "TODO" "FEEDBACK" "VERIFY" "|" "DONE" "DELEGATED")))
 
    The vertical bar separates the TODO keywords (states that _need
 action_) from the DONE states (which need _no further action_).  If you
 do not provide the separator bar, the last state is used as the DONE
 state.
 
    With this setup, the command ‘C-c C-t’ cycles an entry from ‘TODO’ to
 ‘FEEDBACK’, then to ‘VERIFY’, and finally to ‘DONE’ and ‘DELEGATED’.
 You may also use a numeric prefix argument to quickly select a specific
 state.  For example ‘C-3 C-c C-t’ changes the state immediately to
 ‘VERIFY’.  Or you can use ‘S-<RIGHT>’ and ‘S-<LEFT>’ to go forward and
 backward through the states.  If you define many keywords, you can use
 in-buffer completion (see *note Completion::) or a special one-key
 selection scheme (see *note Fast access to TODO states::) to insert
 these words into the buffer.  Changing a TODO state can be logged with a
 timestamp, see *note Tracking TODO state changes::, for more
 information.

 after restarting Org mode in a buffer.

 5.2.2 TODO keywords as types
 ----------------------------
 
 The second possibility is to use TODO keywords to indicate different
 _types_ of action items.  For example, you might want to indicate that
 items are for “work” or “home”.  Or, when you work with several people
 on a single project, you might want to assign action items directly to
 persons, by using their names as TODO keywords.  This type of
 functionality is actually much better served by using tags (see *note
 Tags::), so the TODO implementation is kept just for backward
 compatibility.
 
    Using TODO types, it would be set up like this:
 
      (setq org-todo-keywords '((type "Fred" "Sara" "Lucy" "|" "DONE")))
 
    In this case, different keywords do not indicate states, but rather
 different types.  So the normal work flow would be to assign a task to a
 person, and later to mark it DONE.  Org mode supports this style by
 adapting the workings of the command ‘C-c C-t’(1).  When used several
 times in succession, it still cycles through all names, in order to
 first select the right type for a task.  But when you return to the item
 after some time and execute ‘C-c C-t’ again, it will switch from any
 name directly to ‘DONE’.  Use prefix arguments or completion to quickly
 select a specific name.  You can also review the items of a specific
 TODO type in a sparse tree by using a numeric prefix to ‘C-c / t’.  For
 example, to see all things Lucy has to do, you would use ‘C-3 C-c / t’.
 To collect Lucy’s items from all agenda files into a single buffer, you
 would use the numeric prefix argument as well when creating the global
 TODO list: ‘C-3 M-x org-agenda t’.
 
    ---------- Footnotes ----------
 
    (1) This is also true for the ‘t’ command in the agenda buffer.
 
 
 File: org.info,  Node: Multiple sets in one file,  Next: Fast access to TODO states,  Prev: TODO types,  Up: TODO Extensions
 
 5.2.3 Multiple keyword sets in one file
 ---------------------------------------
 
 Sometimes you may want to use different sets of TODO keywords in
 parallel.  For example, you may want to have the basic TODO/DONE, but
 also a workflow for bug fixing, and a separate state indicating that an
 item has been canceled—so it is not DONE, but also does not require
 action.  Your setup would then look like this:
 
      (setq org-todo-keywords
            '((sequence "TODO" "|" "DONE")
              (sequence "REPORT" "BUG" "KNOWNCAUSE" "|" "FIXED")
              (sequence "|" "CANCELED")))
 
    The keywords should all be different, this helps Org mode keep track
 of which subsequence should be used for a given entry.  In this setup,
 ‘C-c C-t’ only operates within a sub-sequence, so it switches from
 ‘DONE’ to (nothing) to ‘TODO’, and from ‘FIXED’ to (nothing) to
 ‘REPORT’.  Therefore you need a mechanism to initially select the
 correct sequence.  In addition to typing a keyword or using completion
 (see *note Completion::), you may also apply the following commands:
 
 ‘C-u C-u C-c C-t’
 ‘C-S-<RIGHT>’
 ‘C-S-<LEFT>’
      These keys jump from one TODO sub-sequence to the next.  In the
      above example, ‘C-u C-u C-c C-t’ or ‘C-S-<RIGHT>’ would jump from
      ‘TODO’ or ‘DONE’ to ‘REPORT’, and any of the words in the second
      row to ‘CANCELED’.  Note that the ‘C-S-’ key binding conflict with
      shift-selection (see *note Conflicts::).
 
 ‘S-<RIGHT>’
 ‘S-<LEFT>’
      ‘S-<LEFT>’ and ‘S-<RIGHT>’ walk through _all_ keywords from all
      sub-sequences, so for example ‘S-<RIGHT>’ would switch from ‘DONE’
      to ‘REPORT’ in the example above.  For a discussion of the
      interaction with shift-selection, see *note Conflicts::.
 
 
 File: org.info,  Node: Fast access to TODO states,  Next: Per-file keywords,  Prev: Multiple sets in one file,  Up: TODO Extensions
 
 5.2.4 Fast access to TODO states
 --------------------------------
 
 If you would like to quickly change an entry to an arbitrary TODO state
 instead of cycling through the states, you can set up keys for
 single-letter access to the states.  This is done by adding the
 selection character after each keyword, in parentheses(1).  For example:
 
      (setq org-todo-keywords
            '((sequence "TODO(t)" "|" "DONE(d)")
              (sequence "REPORT(r)" "BUG(b)" "KNOWNCAUSE(k)" "|" "FIXED(f)")
              (sequence "|" "CANCELED(c)")))
 
    If you then press ‘C-c C-t’ followed by the selection key, the entry
 is switched to this state.  ‘<SPC>’ can be used to remove any TODO
 keyword from an entry.
 
    ---------- Footnotes ----------
 
    (1) All characters are allowed except ‘@’, ‘^’ and ‘!’, which have a
 special meaning here.
 
 
 File: org.info,  Node: Per-file keywords,  Next: Faces for TODO keywords,  Prev: Fast access to TODO states,  Up: TODO Extensions
 
 5.2.5 Setting up keywords for individual files
 ----------------------------------------------
 
 It can be very useful to use different aspects of the TODO mechanism in
 different files.  For file-local settings, you need to add special lines
 to the file which set the keywords and interpretation for that file
 only.  For example, to set one of the two examples discussed above, you
 need one of the following lines, starting in column zero anywhere in the
 file:
 
      #+TODO: TODO FEEDBACK VERIFY | DONE CANCELED
 
    You may also write ‘#+SEQ_TODO’ to be explicit about the
 interpretation, but it means the same as ‘#+TODO’, or
 
      #+TYP_TODO: Fred Sara Lucy Mike | DONE
 
    A setup for using several sets in parallel would be:
 
      #+TODO: TODO(t) | DONE(d)
      #+TODO: REPORT(r) BUG(b) KNOWNCAUSE(k) | FIXED(f)
      #+TODO: | CANCELED(c)
 
    To make sure you are using the correct keyword, type ‘#+’ into the
 buffer and then use ‘M-<TAB>’ to complete it (see *note Completion::).
 
    Remember that the keywords after the vertical bar—or the last keyword
 if no bar is there—must always mean that the item is DONE, although you
 may use a different word.  After changing one of these lines, use ‘C-c
 C-c’ with point still in the line to make the changes known to Org
 mode(1).
 
    ---------- Footnotes ----------
 
    (1) Org mode parses these lines only when Org mode is activated after
 visiting a file.  ‘C-c C-c’ with point in a line starting with ‘#+’ is
 simply restarting Org mode for the current buffer.
 
 
 File: org.info,  Node: Faces for TODO keywords,  Next: TODO dependencies,  Prev: Per-file keywords,  Up: TODO Extensions
 
 5.2.6 Faces for TODO keywords
 -----------------------------
 
 Org mode highlights TODO keywords with special faces: ‘org-todo’ for
 keywords indicating that an item still has to be acted upon, and
 ‘org-done’ for keywords indicating that an item is finished.  If you are
 using more than two different states, you might want to use special
 faces for some of them.  This can be done using the variable
 ‘org-todo-keyword-faces’.  For example:
 
      (setq org-todo-keyword-faces
            '(("TODO" . org-warning) ("STARTED" . "yellow")
              ("CANCELED" . (:foreground "blue" :weight bold))))
 
    While using a list with face properties as shown for ‘CANCELED’
 _should_ work, this does not always seem to be the case.  If necessary,
 define a special face and use that.  A string is interpreted as a color.
 The variable ‘org-faces-easy-properties’ determines if that color is
 interpreted as a foreground or a background color.
 
 
 File: org.info,  Node: TODO dependencies,  Prev: Faces for TODO keywords,  Up: TODO Extensions
 
 5.2.7 TODO dependencies
 -----------------------
 
 The structure of Org files—hierarchy and lists—makes it easy to define
 TODO dependencies.  Usually, a parent TODO task should not be marked as
 done until all TODO subtasks, or children tasks, are marked as done.
 Sometimes there is a logical sequence to (sub)tasks, so that one subtask
 cannot be acted upon before all siblings above it have been marked as
 done.  If you customize the variable ‘org-enforce-todo-dependencies’,
 Org blocks entries from changing state to DONE while they have TODO
 children that are not DONE.  Furthermore, if an entry has a property
 ‘ORDERED’, each of its TODO children is blocked until all earlier
 siblings are marked as done.  Here is an example:
 
      * TODO Blocked until (two) is done
      ** DONE one
      ** TODO two
 
      * Parent
      :PROPERTIES:
      :ORDERED:  t
      :END:
      ** TODO a
      ** TODO b, needs to wait for (a)
      ** TODO c, needs to wait for (a) and (b)
 
    You can ensure an entry is never blocked by using the ‘NOBLOCKING’
 property (see *note Properties and Columns::):
 
      * This entry is never blocked
      :PROPERTIES:
      :NOBLOCKING: t
      :END:
 
 ‘C-c C-x o’ (‘org-toggle-ordered-property’)
      Toggle the ‘ORDERED’ property of the current entry.  A property is
      used for this behavior because this should be local to the current
      entry, not inherited from entries above like a tag (see *note
      Tags::).  However, if you would like to _track_ the value of this
      property with a tag for better visibility, customize the variable
      ‘org-track-ordered-property-with-tag’.
 
 ‘C-u C-u C-u C-c C-t’
      Change TODO state, regardless of any state blocking.
 
    If you set the variable ‘org-agenda-dim-blocked-tasks’, TODO entries
 that cannot be marked as done because of unmarked children are shown in
 a dimmed font or even made invisible in agenda views (see *note Agenda
 Views::).
 
    You can also block changes of TODO states by using checkboxes (see
 *note Checkboxes::).  If you set the variable
 ‘org-enforce-todo-checkbox-dependencies’, an entry that has unchecked
 checkboxes is blocked from switching to DONE.
 
    If you need more complex dependency structures, for example
 dependencies between entries in different trees or files, check out the
 module ‘org-depend.el’ in the ‘org-contrib’ repository.
 
 
 File: org.info,  Node: Progress Logging,  Next: Priorities,  Prev: TODO Extensions,  Up: TODO Items
 
 5.3 Progress Logging
 ====================
 
 To record a timestamp and a note when changing a TODO state, call the
 command ‘org-todo’ with a prefix argument.
 
 ‘C-u C-c C-t’ (‘org-todo’)
      Prompt for a note and record a the time of the TODO state change.
      The note is inserted as a list item below the headline, but can
      also be placed into a drawer, see *note Tracking TODO state
      changes::.
 
    If you want to be more systematic, Org mode can automatically record
 a timestamp and optionally a note when you mark a TODO item as DONE, or
 even each time you change the state of a TODO item.  This system is
 highly configurable, settings can be on a per-keyword basis and can be
 localized to a file or even a subtree.  For information on how to clock
 working time for a task, see *note Clocking Work Time::.

 * Closing items::                When was this entry marked as done?
 * Tracking TODO state changes::  When did the status change?
 * Tracking your habits::         How consistent have you been?
 
 
 File: org.info,  Node: Closing items,  Next: Tracking TODO state changes,  Up: Progress Logging
 
 5.3.1 Closing items
 -------------------
 
 The most basic automatic logging is to keep track of _when_ a certain
 TODO item was marked as done.  This can be achieved with(1)
 
      (setq org-log-done 'time)
 
 Then each time you turn an entry from a TODO (not-done) state into any
 of the DONE states, a line ‘CLOSED: [timestamp]’ is inserted just after
 the headline.  If you turn the entry back into a TODO item through
 further state cycling, that line is removed again.  If you turn the
 entry back to a non-TODO state (by pressing ‘C-c C-t <SPC>’ for
 example), that line is also removed, unless you set
 ‘org-closed-keep-when-no-todo’ to non-‘nil’.  If you want to record a
 note along with the timestamp, use(2)
 
      (setq org-log-done 'note)
 
 You are then prompted for a note, and that note is stored below the
 entry with a ‘Closing Note’ heading.
 
    ---------- Footnotes ----------
 
    (1) The corresponding in-buffer setting is: ‘#+STARTUP: logdone’.
 
    (2) The corresponding in-buffer setting is: ‘#+STARTUP: lognotedone’.
 
 
 File: org.info,  Node: Tracking TODO state changes,  Next: Tracking your habits,  Prev: Closing items,  Up: Progress Logging
 
 5.3.2 Tracking TODO state changes
 ---------------------------------
 
 You might want to automatically keep track of when a state change
 occurred and maybe take a note about this change.  You can either record
 just a timestamp, or a time-stamped note.  These records are inserted
 after the headline as an itemized list, newest first(1).  When taking a
 lot of notes, you might want to get the notes out of the way into a
 drawer (see *note Drawers::).  Customize the variable
 ‘org-log-into-drawer’ to get this behavior—the recommended drawer for
 this is called ‘LOGBOOK’(2).  You can also overrule the setting of this
 variable for a subtree by setting a ‘LOG_INTO_DRAWER’ property.
 
    Since it is normally too much to record a note for every state, Org
 mode expects configuration on a per-keyword basis for this.  This is
 achieved by adding special markers ‘!’ (for a timestamp) or ‘@’ (for a
 note with timestamp) in parentheses after each keyword.  For example,
 with the setting
 
      (setq org-todo-keywords
            '((sequence "TODO(t)" "WAIT(w@/!)" "|" "DONE(d!)" "CANCELED(c@)")))
 
    You not only define global TODO keywords and fast access keys, but
 also request that a time is recorded when the entry is set to ‘DONE’,
 and that a note is recorded when switching to ‘WAIT’ or ‘CANCELED’(3).
 The setting for ‘WAIT’ is even more special: the ‘!’ after the slash
 means that in addition to the note taken when entering the state, a
 timestamp should be recorded when _leaving_ the ‘WAIT’ state, if and
 only if the _target_ state does not configure logging for entering it.
 So it has no effect when switching from ‘WAIT’ to ‘DONE’, because ‘DONE’
 is configured to record a timestamp only.  But when switching from
 ‘WAIT’ back to ‘TODO’, the ‘/!’ in the ‘WAIT’ setting now triggers a
 timestamp even though ‘TODO’ has no logging configured.
 
    You can use the exact same syntax for setting logging preferences
 local to a buffer:
 
      #+TODO: TODO(t) WAIT(w@/!) | DONE(d!) CANCELED(c@)
 
    To record a timestamp without a note for TODO keywords configured
 with ‘@’, just type ‘C-c C-c’ to enter a blank note when prompted.
 
    In order to define logging settings that are local to a subtree or a
 single item, define a ‘LOGGING’ property in this entry.  Any non-empty
 ‘LOGGING’ property resets all logging settings to ‘nil’.  You may then
 turn on logging for this specific tree using ‘STARTUP’ keywords like
 ‘lognotedone’ or ‘logrepeat’, as well as adding state specific settings
 like ‘TODO(!)’.  For example:
 
      * TODO Log each state with only a time
        :PROPERTIES:
        :LOGGING: TODO(!) WAIT(!) DONE(!) CANCELED(!)
        :END:
      * TODO Only log when switching to WAIT, and when repeating
        :PROPERTIES:
        :LOGGING: WAIT(@) logrepeat
        :END:
      * TODO No logging at all
        :PROPERTIES:
        :LOGGING: nil
        :END:
 
    ---------- Footnotes ----------
 
    (1) See the variable ‘org-log-states-order-reversed’.
 
    (2) Note that the ‘LOGBOOK’ drawer is unfolded when pressing ‘<SPC>’
 in the agenda to show an entry—use ‘C-u <SPC>’ to keep it folded here.
 
    (3) It is possible that Org mode records two timestamps when you are
 using both ‘org-log-done’ and state change logging.  However, it never
 prompts for two notes: if you have configured both, the state change
 recording note takes precedence and cancel the closing note.
 
 
 File: org.info,  Node: Tracking your habits,  Prev: Tracking TODO state changes,  Up: Progress Logging
 
 5.3.3 Tracking your habits
 --------------------------
 
 Org has the ability to track the consistency of a special category of
 TODO, called “habits.” To use habits, you have to enable the ‘habit’
 module by customizing the variable ‘org-modules’.
 
    A habit has the following properties:
 
   1. The habit is a TODO item, with a TODO keyword representing an open
      state.
 
   2. The property ‘STYLE’ is set to the value ‘habit’ (see *note
      Properties and Columns::).
 
   3. The TODO has a scheduled date, usually with a ‘.+’ style repeat
      interval.  A ‘++’ style may be appropriate for habits with time
      constraints, e.g., must be done on specific days of week (‘++1w’),
      or a ‘+’ style for an unusual habit that can have a backlog, e.g.,
      weekly reports.  See *note Repeated tasks:: for more details about
      repeat intervals.
 
   4. The TODO may also have minimum and maximum ranges specified by
      using the syntax ‘.+2d/3d’, which says that you want to do the task
      at least every three days, but at most every two days.
 
   5. State logging for the DONE state is enabled (see *note Tracking
      TODO state changes::), in order for historical data to be
      represented in the consistency graph.  If it is not enabled it is
      not an error, but the consistency graphs are largely meaningless.
 
    To give you an idea of what the above rules look like in action,
 here’s an actual habit with some history:
 
      ** TODO Shave
         SCHEDULED: <2009-10-17 Sat .+2d/4d>
         :PROPERTIES:
         :STYLE:    habit
         :LAST_REPEAT: [2009-10-19 Mon 00:36]
         :END:
         - State "DONE"       from "TODO"       [2009-10-15 Thu]
         - State "DONE"       from "TODO"       [2009-10-12 Mon]
         - State "DONE"       from "TODO"       [2009-10-10 Sat]
         - State "DONE"       from "TODO"       [2009-10-04 Sun]
         - State "DONE"       from "TODO"       [2009-10-02 Fri]
         - State "DONE"       from "TODO"       [2009-09-29 Tue]
         - State "DONE"       from "TODO"       [2009-09-25 Fri]
         - State "DONE"       from "TODO"       [2009-09-19 Sat]
         - State "DONE"       from "TODO"       [2009-09-16 Wed]
         - State "DONE"       from "TODO"       [2009-09-12 Sat]
 
    What this habit says is: I want to shave at most every 2 days—given
 by the ‘SCHEDULED’ date and repeat interval—and at least every 4 days.
 If today is the 15th, then the habit first appears in the agenda (see
 *note Agenda Views::) on Oct 17, after the minimum of 2 days has
 elapsed, and will appear overdue on Oct 19, after four days have
 elapsed.
 
    What’s really useful about habits is that they are displayed along
 with a consistency graph, to show how consistent you’ve been at getting
 that task done in the past.  This graph shows every day that the task
 was done over the past three weeks, with colors for each day.  The
 colors used are:
 
 Blue
      If the task was not to be done yet on that day.
 Green
      If the task could have been done on that day.
 Yellow
      If the task was going to be overdue the next day.
 Red
      If the task was overdue on that day.
 
    In addition to coloring each day, the day is also marked with an
 asterisk if the task was actually done that day, and an exclamation mark
 to show where the current day falls in the graph.
 
    There are several configuration variables that can be used to change
 the way habits are displayed in the agenda.
 
 ‘org-habit-graph-column’
      The buffer column at which the consistency graph should be drawn.
      This overwrites any text in that column, so it is a good idea to
      keep your habits’ titles brief and to the point.
 
 ‘org-habit-preceding-days’
      The amount of history, in days before today, to appear in
      consistency graphs.
 
 ‘org-habit-following-days’
      The number of days after today that appear in consistency graphs.
 
 ‘org-habit-show-habits-only-for-today’
      If non-‘nil’, only show habits in today’s agenda view.  The default
      value is ‘t’.  Pressing ‘C-u K’ in the agenda toggles this
      variable.
 
    Lastly, pressing ‘K’ in the agenda buffer causes habits to
 temporarily be disabled and do not appear at all.  Press ‘K’ again to
 bring them back.  They are also subject to tag filtering, if you have
 habits which should only be done in certain contexts, for example.

 5.4 Priorities
 ==============
 
 If you use Org mode extensively, you may end up with enough TODO items
 that it starts to make sense to prioritize them.  Prioritizing can be
 done by placing a _priority cookie_ into the headline of a TODO item
 right after the TODO keyword, like this:
 
      *** TODO [#A] Write letter to Sam Fortune
 
    By default, Org mode supports three priorities: ‘A’, ‘B’, and ‘C’.
 ‘A’ is the highest priority.  An entry without a cookie is treated as
 equivalent if it had priority ‘B’.  Priorities make a difference only
 for sorting in the agenda (see *note Weekly/daily agenda::).  Outside
 the agenda, they have no inherent meaning to Org mode.  The cookies are
 displayed with the face defined by the variable ‘org-priority-faces’,
 which can be customized.
 
    You can also use numeric values for priorities, such as
 
      *** TODO [#1] Write letter to Sam Fortune
 
    When using numeric priorities, you need to set
 ‘org-priority-highest’, ‘org-priority-lowest’ and ‘org-priority-default’
 to integers, which must all be strictly inferior to 65.
 
    Priorities can be attached to any outline node; they do not need to
 be TODO items.
 
 ‘C-c ,’ (‘org-priority’)
      Set the priority of the current headline.  The command prompts for
      a priority character ‘A’, ‘B’ or ‘C’.  When you press ‘<SPC>’
      instead, the priority cookie, if one is set, is removed from the
      headline.  The priorities can also be changed “remotely” from the
      agenda buffer with the ‘,’ command (see *note Agenda Commands::).
 
 ‘S-<UP>’ (‘org-priority-up’)
 ‘S-<DOWN>’ (‘org-priority-down’)
      Increase/decrease the priority of the current headline(1).  Note
      that these keys are also used to modify timestamps (see *note
      Creating Timestamps::).  See also *note Conflicts::, for a
      discussion of the interaction with shift-selection.
 
    You can change the range of allowed priorities by setting the
 variables ‘org-priority-highest’, ‘org-priority-lowest’, and
 ‘org-priority-default’.  For an individual buffer, you may set these
 values (highest, lowest, default) like this (please make sure that the
 highest priority is earlier in the alphabet than the lowest priority):
 
      #+PRIORITIES: A C B
 
    Or, using numeric values:
 
      #+PRIORITIES: 1 10 5

    (1) See also the option ‘org-priority-start-cycle-with-default’.
 
 
 File: org.info,  Node: Breaking Down Tasks,  Next: Checkboxes,  Prev: Priorities,  Up: TODO Items
 
 5.5 Breaking Down Tasks into Subtasks
 =====================================
 
 It is often advisable to break down large tasks into smaller, manageable
 subtasks.  You can do this by creating an outline tree below a TODO
 item, with detailed subtasks on the tree(1).  To keep an overview of the
 fraction of subtasks that have already been marked as done, insert
 either ‘[/]’ or ‘[%]’ anywhere in the headline.  These cookies are
 updated each time the TODO status of a child changes, or when pressing
 ‘C-c C-c’ on the cookie.  For example:
 
      * Organize Party [33%]
      ** TODO Call people [1/2]
      *** TODO Peter
      *** DONE Sarah
      ** TODO Buy food
      ** DONE Talk to neighbor
 
    If a heading has both checkboxes and TODO children below it, the
 meaning of the statistics cookie become ambiguous.  Set the property
 ‘COOKIE_DATA’ to either ‘checkbox’ or ‘todo’ to resolve this issue.
 
    If you would like to have the statistics cookie count any TODO
 entries in the subtree (not just direct children), configure the
 variable ‘org-hierarchical-todo-statistics’.  To do this for a single
 subtree, include the word ‘recursive’ into the value of the
 ‘COOKIE_DATA’ property.

    If you would like a TODO entry to automatically change to DONE when
 all children are done, you can use the following setup:
 
      (defun org-summary-todo (n-done n-not-done)
        "Switch entry to DONE when all subentries are done, to TODO otherwise."
        (let (org-log-done org-todo-log-states)   ; turn off logging
          (org-todo (if (= n-not-done 0) "DONE" "TODO"))))
 
      (add-hook 'org-after-todo-statistics-hook #'org-summary-todo)
 
    Another possibility is the use of checkboxes to identify (a hierarchy
 of) a large number of subtasks (see *note Checkboxes::).

 5.6 Checkboxes
 ==============
 
 Every item in a plain list(1) (see *note Plain Lists::) can be made into
 a checkbox by starting it with the string ‘[ ]’.  This feature is
 similar to TODO items (see *note TODO Items::), but is more lightweight.
 Checkboxes are not included into the global TODO list, so they are often
 great to split a task into a number of simple steps.  Or you can use
 them in a shopping list.
 
    Here is an example of a checkbox list.
 
      * TODO Organize party [2/4]
        - [-] call people [1/3]
          - [ ] Peter
          - [X] Sarah
          - [ ] Sam
        - [X] order food
        - [ ] think about what music to play
        - [X] talk to the neighbors
 
    The ‘[2/4]’ and ‘[1/3]’ in the first and second line are cookies
 indicating how many checkboxes present in this entry have been checked
 off, and the total number of checkboxes present.  This can give you an
 idea on how many checkboxes remain, even without opening a folded entry.
 The cookies can be placed into a headline or into (the first line of) a
 plain list item.  Each cookie covers checkboxes of direct children
 structurally below the headline/item on which the cookie appears(2).
 You have to insert the cookie yourself by typing either ‘[/]’ or ‘[%]’.
 With ‘[/]’ you get an ‘n out of m’ result, as in the examples above.
 With ‘[%]’ you get information about the percentage of checkboxes
 checked (in the above example, this would be ‘[50%]’ and ‘[33%]’,
 respectively).  In a headline, a cookie can count either checkboxes
 below the heading or TODO states of children, and it displays whatever
 was changed last.  Set the property ‘COOKIE_DATA’ to either ‘checkbox’
 or ‘todo’ to resolve this issue.
 
    If the current outline node has an ‘ORDERED’ property, checkboxes
 must be checked off in sequence, and an error is thrown if you try to
 check off a box while there are unchecked boxes above it.
 
    A checkbox can be in one of the three states:
   1. not checked ‘[ ]’
   2. partially checked ‘[-]’
   3. checked ‘[X]’
 
    Checkboxes work hierarchically, so if a checkbox item has children
 that are checkboxes, toggling one of the children checkboxes makes the
 parent checkbox reflect if none, some, or all of the children are
 checked.
 
    If all child checkboxes are not checked, the parent checkbox is also
 not checked.
      - [ ] call people
        - [ ] Peter
        - [ ] Sarah
 
    If some but not all child checkboxes are checked, the parent checkbox
 is partially checked.
      - [-] call people
        - [X] Peter
        - [ ] Sarah
 
    If all child checkboxes are checked, the parent checkbox is also
 checked.
      - [X] call people
        - [X] Peter
        - [X] Sarah
 
    The following commands work with checkboxes:
 
 ‘C-c C-c’ (‘org-toggle-checkbox’)
      Toggle checkbox status or—with prefix argument—checkbox presence at
      point.  With a single prefix argument, add an empty checkbox or
      remove the current one(3).  With a double prefix argument, set it
      to ‘[-]’, which is considered to be an intermediate state.
 
 ‘C-c C-x C-b’ (‘org-toggle-checkbox’)
      Toggle checkbox status or—with prefix argument—checkbox presence at
      point.  With double prefix argument, set it to ‘[-]’, which is
      considered to be an intermediate state.
 
         • If there is an active region, toggle the first checkbox in the
           region and set all remaining boxes to the same status as the
           first.  With a prefix argument, add or remove the checkbox for
           all items in the region.
 
         • If point is in a headline, toggle checkboxes in the region
           between this headline and the next—so _not_ the entire
           subtree.
 
         • If there is no active region, just toggle the checkbox at
           point.
 
 ‘C-c C-x C-r’ (‘org-toggle-radio-button’)
      Toggle checkbox status by using the checkbox of the item at point
      as a radio button: when the checkbox is turned on, all other
      checkboxes on the same level will be turned off.  With a universal
      prefix argument, toggle the presence of the checkbox.  With a
      double prefix argument, set it to ‘[-]’.
 
      ‘C-c C-c’ can be told to consider checkboxes as radio buttons by
      setting ‘#+ATTR_ORG: :radio t’ right before the list or by calling
      ‘M-x org-list-checkbox-radio-mode’ to activate this minor mode.
 
 ‘M-S-<RET>’ (‘org-insert-todo-heading’)
      Insert a new item with a checkbox.  This works only if point is
      already in a plain list item (see *note Plain Lists::).
 
 ‘C-c C-x o’ (‘org-toggle-ordered-property’)
      Toggle the ‘ORDERED’ property of the entry, to toggle if checkboxes
      must be checked off in sequence.  A property is used for this
      behavior because this should be local to the current entry, not
      inherited like a tag.  However, if you would like to _track_ the
      value of this property with a tag for better visibility, customize
      ‘org-track-ordered-property-with-tag’.
 
 ‘C-c #’ (‘org-update-statistics-cookies’)
      Update the statistics cookie in the current outline entry.  When
      called with a ‘C-u’ prefix, update the entire file.  Checkbox
      statistic cookies are updated automatically if you toggle
      checkboxes with ‘C-c C-c’ and make new ones with ‘M-S-<RET>’.  TODO
      statistics cookies update when changing TODO states.  If you delete
      boxes/entries or add/change them by hand, use this command to get
      things back into sync.
 
    ---------- Footnotes ----------
 
    (1) With the exception of description lists.  But you can allow it by
 modifying ‘org-list-automatic-rules’ accordingly.
 
    (2) Set the variable ‘org-checkbox-hierarchical-statistics’ if you
 want such cookies to count all checkboxes below the cookie, not just
 those belonging to direct children.
 
    (3) ‘C-u C-c C-c’ on the _first_ item of a list with no checkbox adds
 checkboxes to the rest of the list.

 6 Tags
 ******
 
 An excellent way to implement labels and contexts for cross-correlating
 information is to assign _tags_ to headlines.  Org mode has extensive
 support for tags.
 
    Every headline can contain a list of tags; they occur at the end of
 the headline.  Tags are normal words containing letters, numbers, ‘_’,
 and ‘@’.  Tags must be preceded and followed by a single colon, e.g.,
 ‘:work:’.  Several tags can be specified, as in ‘:work:urgent:’.  Tags
 by default are in bold face with the same color as the headline.  You
 may specify special faces for specific tags using the variable
 ‘org-tag-faces’, in much the same way as you can for TODO keywords (see
 *note Faces for TODO keywords::).

 6.1 Tag Inheritance
 ===================
 
 _Tags_ make use of the hierarchical structure of outline trees.  If a
 heading has a certain tag, all subheadings inherit the tag as well.  For
 example, in the list
 
      * Meeting with the French group      :work:
      ** Summary by Frank                  :boss:notes:
      *** TODO Prepare slides for him      :action:
 
 the final heading has the tags ‘work’, ‘boss’, ‘notes’, and ‘action’
 even though the final heading is not explicitly marked with those tags.
 You can also set tags that all entries in a file should inherit just as
 if these tags were defined in a hypothetical level zero that surrounds
 the entire file.  Use a line like this(1)
 
      #+FILETAGS: :Peter:Boss:Secret:
 
    To limit tag inheritance to specific tags, or to turn it off
 entirely, use the variables ‘org-use-tag-inheritance’ and
 ‘org-tags-exclude-from-inheritance’.
 
    Tag inheritance is relevant when the agenda search tries to match a
 tag, either in the ‘tags’ or ‘tags-todo’ agenda types.  In other agenda
 types, ‘org-use-tag-inheritance’ has no effect.  Still, you may want to
 have your tags correctly set in the agenda, so that tag filtering works
 fine, with inherited tags.  Set ‘org-agenda-use-tag-inheritance’ to
 control this: the default value includes all agenda types, but setting
 this to ‘nil’ can really speed up agenda generation.
 
    ---------- Footnotes ----------
 
    (1) As with all these in-buffer settings, pressing ‘C-c C-c’
 activates any changes in the line.

 6.2 Setting Tags
 ================
 
 Tags can simply be typed into the buffer at the end of a headline.
 After a colon, ‘M-<TAB>’ offers completion on tags.  There is also a
 special command for inserting tags:
 
 ‘C-c C-q’ (‘org-set-tags-command’)
      Enter new tags for the current headline.  Org mode either offers
      completion or a special single-key interface for setting tags, see
      below.  After pressing ‘<RET>’, the tags are inserted and aligned
      to ‘org-tags-column’.  When called with a ‘C-u’ prefix, all tags in
      the current buffer are aligned to that column, just to make things
      look nice.  Tags are automatically realigned after promotion,
      demotion, and TODO state changes (see *note TODO Basics::).
 
 ‘C-c C-c’ (‘org-set-tags-command’)
      When point is in a headline, this does the same as ‘C-c C-q’.
 
    Org supports tag insertion based on a _list of tags_.  By default
 this list is constructed dynamically, containing all tags currently used
 in the buffer(1).  You may also globally specify a hard list of tags
 with the variable ‘org-tag-alist’.  Finally you can set the default tags
 for a given file using the ‘TAGS’ keyword, like
 
      #+TAGS: @work @home @tennisclub
      #+TAGS: laptop car pc sailboat
 
    If you have globally defined your preferred set of tags using the
 variable ‘org-tag-alist’, but would like to use a dynamic tag list in a
 specific file, add an empty ‘TAGS’ keyword to that file:
 
      #+TAGS:
 
    If you have a preferred set of tags that you would like to use in
 every file, in addition to those defined on a per-file basis by ‘TAGS’
 keyword, then you may specify a list of tags with the variable
 ‘org-tag-persistent-alist’.  You may turn this off on a per-file basis
 by adding a ‘STARTUP’ keyword to that file:
 
      #+STARTUP: noptag
 
    By default Org mode uses the standard minibuffer completion
 facilities for entering tags.  However, it also implements another,
 quicker, tag selection method called _fast tag selection_.  This allows
 you to select and deselect tags with just a single key press.  For this
 to work well you should assign unique letters to most of your commonly
 used tags.  You can do this globally by configuring the variable
 ‘org-tag-alist’ in your Emacs init file.  For example, you may find the
 need to tag many items in different files with ‘@home’.  In this case
 you can set something like:
 
      (setq org-tag-alist '(("@work" . ?w) ("@home" . ?h) ("laptop" . ?l)))
 
    If the tag is only relevant to the file you are working on, then you
 can instead set the ‘TAGS’ keyword as:
 
      #+TAGS: @work(w)  @home(h)  @tennisclub(t)  laptop(l)  pc(p)
 
    The tags interface shows the available tags in a splash window.  If
 you want to start a new line after a specific tag, insert ‘\n’ into the
 tag list
 
      #+TAGS: @work(w) @home(h) @tennisclub(t) \n laptop(l) pc(p)
 
 or write them in two lines:
 
      #+TAGS: @work(w)  @home(h)  @tennisclub(t)
      #+TAGS: laptop(l)  pc(p)
 
    You can also group together tags that are mutually exclusive by using
 braces, as in:
 
      #+TAGS: { @work(w)  @home(h)  @tennisclub(t) }  laptop(l)  pc(p)
 
 you indicate that at most one of ‘@work’, ‘@home’, and ‘@tennisclub’
 should be selected.  Multiple such groups are allowed.
 
    Do not forget to press ‘C-c C-c’ with point in one of these lines to
 activate any changes.
 
    To set these mutually exclusive groups in the variable
 ‘org-tags-alist’, you must use the dummy tags ‘:startgroup’ and
 ‘:endgroup’ instead of the braces.  Similarly, you can use ‘:newline’ to
 indicate a line break.  The previous example would be set globally by
 the following configuration:
 
      (setq org-tag-alist '((:startgroup . nil)
                            ("@work" . ?w) ("@home" . ?h)
                            ("@tennisclub" . ?t)
                            (:endgroup . nil)
                            ("laptop" . ?l) ("pc" . ?p)))
 
    If at least one tag has a selection key then pressing ‘C-c C-c’
 automatically presents you with a special interface, listing inherited
 tags, the tags of the current headline, and a list of all valid tags
 with corresponding keys(2).
 
    Pressing keys assigned to tags adds or removes them from the list of
 tags in the current line.  Selecting a tag in a group of mutually
 exclusive tags turns off any other tag from that group.
 
    In this interface, you can also use the following special keys:
 
 ‘<TAB>’
      Enter a tag in the minibuffer, even if the tag is not in the
      predefined list.  You can complete on all tags present in the
      buffer and globally pre-defined tags from ‘org-tag-alist’ and
      ‘org-tag-persistent-alist’.  You can also add several tags: just
      separate them with a comma.
 
 ‘<SPC>’
      Clear all tags for this line.
 
 ‘<RET>’
      Accept the modified set.
 
 ‘C-g’
      Abort without installing changes.
 
 ‘q’
      If ‘q’ is not assigned to a tag, it aborts like ‘C-g’.
 
 ‘!’
      Turn off groups of mutually exclusive tags.  Use this to (as an
      exception) assign several tags from such a group.
 
 ‘C-c’
      Toggle auto-exit after the next change (see below).  If you are
      using expert mode, the first ‘C-c’ displays the selection window.
 
    This method lets you assign tags to a headline with very few keys.
 With the above setup, you could clear the current tags and set ‘@home’,
 ‘laptop’ and ‘pc’ tags with just the following keys: ‘C-c C-c <SPC> h l
 p <RET>’.  Switching from ‘@home’ to ‘@work’ would be done with ‘C-c C-c
 w <RET>’ or alternatively with ‘C-c C-c C-c w’.  Adding the
 non-predefined tag ‘sarah’ could be done with ‘C-c C-c <TAB> s a r a h
 <RET>’.
 
    If you find that most of the time you need only a single key press to
 modify your list of tags, set the variable
 ‘org-fast-tag-selection-single-key’.  Then you no longer have to press
 ‘<RET>’ to exit fast tag selection—it exits after the first change.  If
 you then occasionally need more keys, press ‘C-c’ to turn off auto-exit
 for the current tag selection process (in effect: start selection with
 ‘C-c C-c C-c’ instead of ‘C-c C-c’).  If you set the variable to the
 value ‘expert’, the special window is not even shown for single-key tag
 selection, it comes up only when you press an extra ‘C-c’.
 
    The number of tags displayed in the fast tag selection interface is
 limited by ‘org-fast-tag-selection-maximum-tags’ to avoid running out of
 keyboard keys.  You can customize this variable.
 
    ---------- Footnotes ----------
 
    (1) To extend this default list to all tags used in all agenda files
 (see *note Agenda Views::), customize the variable
 ‘org-complete-tags-always-offer-all-agenda-tags’.
 
    (2) Keys are automatically assigned to tags that have no configured
 keys.

 6.3 Tag Hierarchy
 =================
 
 Tags can be defined in hierarchies.  A tag can be defined as a _group
 tag_ for a set of other tags.  The group tag can be seen as the “broader
 term” for its set of tags.  Defining multiple group tags and nesting
 them creates a tag hierarchy.
 
    One use-case is to create a taxonomy of terms (tags) that can be used
 to classify nodes in a document or set of documents.
 
    When you search for a group tag, it return matches for all members in
 the group and its subgroups.  In an agenda view, filtering by a group
 tag displays or hide headlines tagged with at least one of the members
 of the group or any of its subgroups.  This makes tag searches and
 filters even more flexible.
 
    You can set group tags by using brackets and inserting a colon
 between the group tag and its related tags—beware that all whitespaces
 are mandatory so that Org can parse this line correctly:
 
      #+TAGS: [ GTD : Control Persp ]
 
    In this example, ‘GTD’ is the group tag and it is related to two
 other tags: ‘Control’, ‘Persp’.  Defining ‘Control’ and ‘Persp’ as group
 tags creates a hierarchy of tags:
 
      #+TAGS: [ Control : Context Task ]
      #+TAGS: [ Persp : Vision Goal AOF Project ]
 
    That can conceptually be seen as a hierarchy of tags:
 
    • ‘GTD’
         • ‘Persp’
              • ‘Vision’
              • ‘Goal’
              • ‘AOF’
              • ‘Project’
         • ‘Control’
              • ‘Context’
              • ‘Task’
 
    You can use the ‘:startgrouptag’, ‘:grouptags’ and ‘:endgrouptag’
 keyword directly when setting ‘org-tag-alist’ directly:
 
      (setq org-tag-alist '((:startgrouptag)
                            ("GTD")
                            (:grouptags)
                            ("Control")
                            ("Persp")
                            (:endgrouptag)
                            (:startgrouptag)
                            ("Control")
                            (:grouptags)
                            ("Context")
                            ("Task")
                            (:endgrouptag)))
 
    The tags in a group can be mutually exclusive if using the same group
 syntax as is used for grouping mutually exclusive tags together; using
 curly brackets.
 
      #+TAGS: { Context : @Home @Work @Call }
 
    When setting ‘org-tag-alist’ you can use ‘:startgroup’ and
 ‘:endgroup’ instead of ‘:startgrouptag’ and ‘:endgrouptag’ to make the
 tags mutually exclusive.
 
    Furthermore, the members of a group tag can also be regular
 expressions, creating the possibility of a more dynamic and rule-based
 tag structure (see *note Regular Expressions::).  The regular
 expressions in the group must be specified within curly brackets.  Here
 is an expanded example:
 
      #+TAGS: [ Vision : {V@.+} ]
      #+TAGS: [ Goal : {G@.+} ]
      #+TAGS: [ AOF : {AOF@.+} ]
      #+TAGS: [ Project : {P@.+} ]
 
    Searching for the tag ‘Project’ now lists all tags also including
 regular expression matches for ‘P@.+’, and similarly for tag searches on
 ‘Vision’, ‘Goal’ and ‘AOF’.  For example, this would work well for a
 project tagged with a common project-identifier, e.g., ‘P@2014_OrgTags’.
 
    If you want to ignore group tags temporarily, toggle group tags
 support with ‘org-toggle-tags-groups’, bound to ‘C-c C-x q’.  If you
 want to disable tag groups completely, set ‘org-group-tags’ to ‘nil’.

 6.4 Tag Searches
 ================
 
 Once a system of tags has been set up, it can be used to collect related
 information into special lists.
 
 ‘C-c / m’ or ‘C-c \’ (‘org-match-sparse-tree’)
      Create a sparse tree with all headlines matching a tags search.
      With a ‘C-u’ prefix argument, ignore headlines that are not a TODO
      line.
 
 ‘M-x org-agenda m’ (‘org-tags-view’)
      Create a global list of tag matches from all agenda files.  See
      *note Matching tags and properties::.
 
 ‘M-x org-agenda M’ (‘org-tags-view’)
      Create a global list of tag matches from all agenda files, but
      check only TODO items.
 
    These commands all prompt for a match string which allows basic
 Boolean logic like ‘+boss+urgent-project1’, to find entries with tags
 ‘boss’ and ‘urgent’, but not ‘project1’, or ‘Kathy|Sally’ to find
 entries which are tagged, like ‘Kathy’ or ‘Sally’.  The full syntax of
 the search string is rich and allows also matching against TODO
 keywords, entry levels and properties.  For a complete description with
 many examples, see *note Matching tags and properties::.

 7 Properties and Columns
 ************************
 
 A property is a key-value pair associated with an entry.  Properties can
 be set so they are associated with a single entry, with every entry in a
 tree, or with the whole buffer.
 
    There are two main applications for properties in Org mode.  First,
 properties are like tags, but with a value.  Imagine maintaining a file
 where you document bugs and plan releases for a piece of software.
 Instead of using tags like ‘release_1’, ‘release_2’, you can use a
 property, say ‘Release’, that in different subtrees has different
 values, such as ‘1.0’ or ‘2.0’.  Second, you can use properties to
 implement (very basic) database capabilities in an Org buffer.  Imagine
 keeping track of your music CDs, where properties could be things such
 as the album, artist, date of release, number of tracks, and so on.
 
    Properties can be conveniently edited and viewed in column view (see
 *note Column View::).

 * Property Syntax::              How properties are spelled out.

 File: org.info,  Node: Property Syntax,  Next: Special Properties,  Up: Properties and Columns
 
 7.1 Property Syntax
 ===================
 
 Properties are key–value pairs.  When they are associated with a single
 entry or with a tree they need to be inserted into a special drawer (see
 *note Drawers::) with the name ‘PROPERTIES’, which has to be located
 right below a headline, and its planning line (see *note Deadlines and
 Scheduling::) when applicable.  Each property is specified on a single
 line, with the key—surrounded by colons—first, and the value after it.
 Keys are case-insensitive.  Here is an example:
 
      * CD collection
      ** Classic
      *** Goldberg Variations
          :PROPERTIES:
          :Title:     Goldberg Variations
          :Composer:  J.S. Bach
          :Artist:    Glenn Gould
          :Publisher: Deutsche Grammophon
          :NDisks:    1
          :END:
 
    Depending on the value of ‘org-use-property-inheritance’, a property
 set this way is associated either with a single entry, or with the
 subtree defined by the entry, see *note Property Inheritance::.
 
    You may define the allowed values for a particular property ‘Xyz’ by
 setting a property ‘Xyz_ALL’.  This special property is _inherited_, so
 if you set it in a level 1 entry, it applies to the entire tree.  When
 allowed values are defined, setting the corresponding property becomes
 easier and is less prone to typing errors.  For the example with the CD
 collection, we can pre-define publishers and the number of disks in a
 box like this:
 
      * CD collection
        :PROPERTIES:
        :NDisks_ALL:  1 2 3 4
        :Publisher_ALL: "Deutsche Grammophon" Philips EMI
        :END:
 
    Properties can be inserted at the buffer level.  That means they
 apply before the first headline and can be inherited by all entries in a
 file.  Property blocks defined before the first headline must be at the
 top of the buffer with only comments above them.
 
    Properties can also be defined using lines like:
 
      #+PROPERTY: NDisks_ALL 1 2 3 4
 
    If you want to add to the value of an existing property, append a ‘+’
 to the property name.  The following results in the property ‘var’
 having the value ‘foo=1 bar=2’.
 
      #+PROPERTY: var  foo=1
      #+PROPERTY: var+ bar=2
 
    It is also possible to add to the values of inherited properties.
 The following results in the ‘Genres’ property having the value ‘Classic
 Baroque’ under the ‘Goldberg Variations’ subtree.
 
      * CD collection
      ** Classic
          :PROPERTIES:
          :Genres: Classic
          :END:
      *** Goldberg Variations
          :PROPERTIES:
          :Title:     Goldberg Variations
          :Composer:  J.S. Bach
          :Artist:    Glenn Gould
          :Publisher: Deutsche Grammophon
          :NDisks:    1
          :Genres+:   Baroque
          :END:
 
    Note that a property can only have one entry per drawer.
 
    Property values set with the global variable ‘org-global-properties’
 can be inherited by all entries in all Org files.
 
    The following commands help to work with properties:
 
 ‘M-<TAB>’ (‘pcomplete’)
      After an initial colon in a line, complete property keys.  All keys
      used in the current file are offered as possible completions.
 
 ‘C-c C-x p’ (‘org-set-property’)
      Set a property.  This prompts for a property name and a value.  If
      necessary, the property drawer is created as well.
 
 ‘C-u M-x org-insert-drawer’
      Insert a property drawer into the current entry.  The drawer is
      inserted early in the entry, but after the lines with planning
      information like deadlines.  If before first headline the drawer is
      inserted at the top of the drawer after any potential comments.
 
 ‘C-c C-c’ (‘org-property-action’)
      With point in a property drawer, this executes property commands.
 
 ‘C-c C-c s’ (‘org-set-property’)
      Set a property in the current entry.  Both the property and the
      value can be inserted using completion.
 
 ‘S-<RIGHT>’ (‘org-property-next-allowed-value’)
 ‘S-<LEFT>’ (‘org-property-previous-allowed-value’)
      Switch property at point to the next/previous allowed value.
 
 ‘C-c C-c d’ (‘org-delete-property’)
      Remove a property from the current entry.
 
 ‘C-c C-c D’ (‘org-delete-property-globally’)
      Globally remove a property, from all entries in the current file.
 
 ‘C-c C-c c’ (‘org-compute-property-at-point’)
      Compute the property at point, using the operator and scope from
      the nearest column format definition.

 7.2 Special Properties
 ======================
 
 Special properties provide an alternative access method to Org mode
 features, like the TODO state or the priority of an entry, discussed in
 the previous chapters.  This interface exists so that you can include
 these states in a column view (see *note Column View::), or to use them
 in queries.  The following property names are special and should not be
 used as keys in the properties drawer:
 
 ‘ALLTAGS’        All tags, including inherited ones.
 ‘BLOCKED’        ‘t’ if task is currently blocked by children or siblings.
 ‘CATEGORY’       The category of an entry.
 ‘CLOCKSUM’       The sum of CLOCK intervals in the subtree.  ‘org-clock-sum’
                  must be run first to compute the values in the current buffer.
 ‘CLOCKSUM_T’     The sum of CLOCK intervals in the subtree for today.
                  ‘org-clock-sum-today’ must be run first to compute the
                  values in the current buffer.
 ‘CLOSED’         When was this entry closed?
 ‘DEADLINE’       The deadline timestamp.
 ‘FILE’           The filename the entry is located in.
 ‘ITEM’           The headline of the entry.
 ‘PRIORITY’       The priority of the entry, a string with a single letter.
 ‘SCHEDULED’      The scheduling timestamp.
 ‘TAGS’           The tags defined directly in the headline.
 ‘TIMESTAMP’      The first active keyword-less timestamp in the entry.(1)
 ‘TIMESTAMP_IA’   The first inactive keyword-less timestamp in the entry.
 ‘TODO’           The TODO keyword of the entry.
 
    ---------- Footnotes ----------
 
    (1) For both ‘TIMESTAMP’ and ‘TIMESTAMP_IA’: the word “first” refers
 to the first occurrence in the entry, not the earliest in time; the
 prefix ‘CLOCK:’ at the beginning of a clock entry is considered a
 keyword in this context; and timestamps inside property drawers are
 ignored.

 7.3 Property Searches
 =====================
 
 To create sparse trees and special lists with selection based on
 properties, the same commands are used as for tag searches (see *note
 Tag Searches::).
 
 ‘C-c / m’ or ‘C-c \’ (‘org-match-sparse-tree’)
      Create a sparse tree with all matching entries.  With a ‘C-u’
      prefix argument, ignore headlines that are not a TODO line.
 
 ‘M-x org-agenda m’ (‘org-tags-view’)
      Create a global list of tag/property matches from all agenda files.
 
 ‘M-x org-agenda M’ (‘org-tags-view’)
      Create a global list of tag matches from all agenda files, but
      check only TODO items.
 
    The syntax for the search string is described in *note Matching tags
 and properties::.
 
    There is also a special command for creating sparse trees based on a
 single property:
 
 ‘C-c / p’
      Create a sparse tree based on the value of a property.  This first
      prompts for the name of a property, and then for a value.  A sparse
      tree is created with all entries that define this property with the
      given value.  If you enclose the value in curly braces, it is
      interpreted as a regular expression and matched against the
      property values (see *note Regular Expressions::).
 
 
 File: org.info,  Node: Property Inheritance,  Next: Column View,  Prev: Property Searches,  Up: Properties and Columns
 
 7.4 Property Inheritance
 ========================
 
 The outline structure of Org documents lends itself to an inheritance
 model of properties: if the parent in a tree has a certain property, the
 children can inherit this property.  Org mode does not turn this on by
 default, because it can slow down property searches significantly and is
 often not needed.  However, if you find inheritance useful, you can turn
 it on by setting the variable ‘org-use-property-inheritance’.  It may be
 set to ‘t’ to make all properties inherited from the parent, to a list
 of properties that should be inherited, or to a regular expression that
 matches inherited properties.  If a property has the value ‘nil’, this
 is interpreted as an explicit un-define of the property, so that
 inheritance search stops at this value and returns ‘nil’.
 
    Org mode has a few properties for which inheritance is hard-coded, at
 least for the special applications for which they are used:
 
 ‘COLUMNS’
      The ‘COLUMNS’ property defines the format of column view (see *note
      Column View::).  It is inherited in the sense that the level where
      a ‘COLUMNS’ property is defined is used as the starting point for a
      column view table, independently of the location in the subtree
      from where columns view is turned on.
 
 ‘CATEGORY’
      For agenda view, a category set through a ‘CATEGORY’ property
      applies to the entire subtree.
 
 ‘ARCHIVE’
      For archiving, the ‘ARCHIVE’ property may define the archive
      location for the entire subtree (see *note Moving subtrees::).
 
 ‘LOGGING’
      The ‘LOGGING’ property may define logging settings for an entry or
      a subtree (see *note Tracking TODO state changes::).
 
 
 File: org.info,  Node: Column View,  Prev: Property Inheritance,  Up: Properties and Columns
 
 7.5 Column View
 ===============
 
 A great way to view and edit properties in an outline tree is _column
 view_.  In column view, each outline node is turned into a table row.
 Columns in this table provide access to properties of the entries.  Org
 mode implements columns by overlaying a tabular structure over the
 headline of each item.  While the headlines have been turned into a
 table row, you can still change the visibility of the outline tree.  For
 example, you get a compact table by switching to “contents”
 view—‘S-<TAB>’ ‘S-<TAB>’, or simply ‘c’ while column view is active—but
 you can still open, read, and edit the entry below each headline.  Or,
 you can switch to column view after executing a sparse tree command and
 in this way get a table only for the selected items.  Column view also
 works in agenda buffers (see *note Agenda Views::) where queries have
 collected selected items, possibly from a number of files.

 7.5.1 Defining columns
 ----------------------
 
 Setting up a column view first requires defining the columns.  This is
 done by defining a column format line.
 
 * Menu:
 
 * Scope of column definitions::  Where defined, where valid?
 * Column attributes::            Appearance and content of a column.
 
 
 File: org.info,  Node: Scope of column definitions,  Next: Column attributes,  Up: Defining columns
 
 7.5.1.1 Scope of column definitions
 ...................................
 
 To specify a format that only applies to a specific tree, add a
 ‘COLUMNS’ property to the top node of that tree, for example:
 
      ** Top node for columns view
         :PROPERTIES:
         :COLUMNS: %25ITEM %TAGS %PRIORITY %TODO
         :END:
 
    A ‘COLUMNS’ property within a property drawer before first headline
 will apply to the entire file.  As an addition to property drawers,
 keywords can also be defined for an entire file using a line like:
 
      #+COLUMNS: %25ITEM %TAGS %PRIORITY %TODO
 
    If a ‘COLUMNS’ property is present in an entry, it defines columns
 for the entry itself, and for the entire subtree below it.  Since the
 column definition is part of the hierarchical structure of the document,
 you can define columns on level 1 that are general enough for all
 sublevels, and more specific columns further down, when you edit a
 deeper part of the tree.
 
 
 File: org.info,  Node: Column attributes,  Prev: Scope of column definitions,  Up: Defining columns
 
 7.5.1.2 Column attributes
 .........................
 
 A column definition sets the attributes of a column.  The general
 definition looks like this:
 
      %[WIDTH]PROPERTY[(TITLE)][{SUMMARY-TYPE}]
 
 Except for the percent sign and the property name, all items are
 optional.  The individual parts have the following meaning:
 
 WIDTH
      An integer specifying the width of the column in characters.  If
      omitted, the width is determined automatically.
 
 PROPERTY
      The property that should be edited in this column.  Special
      properties representing meta data are allowed here as well (see
      *note Special Properties::).
 
 TITLE
      The header text for the column.  If omitted, the property name is
      used.
 
 SUMMARY-TYPE
      The summary type.  If specified, the column values for parent nodes
      are computed from the children(1).
 
      Supported summary types are:
 
      ‘+’        Sum numbers in this column.
      ‘+;%.1f’   Like ‘+’, but format result with ‘%.1f’.
      ‘$’        Currency, short for ‘+;%.2f’.
      ‘min’      Smallest number in column.
      ‘max’      Largest number.
      ‘mean’     Arithmetic mean of numbers.
      ‘X’        Checkbox status, ‘[X]’ if all children are ‘[X]’.
      ‘X/’       Checkbox status, ‘[n/m]’.
      ‘X%’       Checkbox status, ‘[n%]’.
      ‘:’        Sum times, HH:MM, plain numbers are minutes.
      ‘:min’     Smallest time value in column.
      ‘:max’     Largest time value.
      ‘:mean’    Arithmetic mean of time values.
      ‘@min’     Minimum age(2) (in days/hours/mins/seconds).
      ‘@max’     Maximum age (in days/hours/mins/seconds).
      ‘@mean’    Arithmetic mean of ages (in days/hours/mins/seconds).
      ‘est+’     Add low-high estimates.
 
      You can also define custom summary types by setting
      ‘org-columns-summary-types’.
 
    The ‘est+’ summary type requires further explanation.  It is used for
 combining estimates, expressed as low-high ranges.  For example, instead
 of estimating a particular task will take 5 days, you might estimate it
 as 5–6 days if you’re fairly confident you know how much work is
 required, or 1–10 days if you do not really know what needs to be done.
 Both ranges average at 5.5 days, but the first represents a more
 predictable delivery.
 
    When combining a set of such estimates, simply adding the lows and
 highs produces an unrealistically wide result.  Instead, ‘est+’ adds the
 statistical mean and variance of the subtasks, generating a final
 estimate from the sum.  For example, suppose you had ten tasks, each of
 which was estimated at 0.5 to 2 days of work.  Straight addition
 produces an estimate of 5 to 20 days, representing what to expect if
 everything goes either extremely well or extremely poorly.  In contrast,
 ‘est+’ estimates the full job more realistically, at 10–15 days.
 
    Here is an example for a complete columns definition, along with
 allowed values(3).
 
      :COLUMNS:  %25ITEM %9Approved(Approved?){X} %Owner %11Status \
                         %10Time_Estimate{:} %CLOCKSUM %CLOCKSUM_T
      :Owner_ALL:    Tammy Mark Karl Lisa Don
      :Status_ALL:   "In progress" "Not started yet" "Finished" ""
      :Approved_ALL: "[ ]" "[X]"
 
 The first column, ‘%25ITEM’, means the first 25 characters of the item
 itself, i.e., of the headline.  You probably always should start the
 column definition with the ‘ITEM’ specifier.  The other specifiers
 create columns ‘Owner’ with a list of names as allowed values, for
 ‘Status’ with four different possible values, and for a checkbox field
 ‘Approved’.  When no width is given after the ‘%’ character, the column
 is exactly as wide as it needs to be in order to fully display all
 values.  The ‘Approved’ column does have a modified title (‘Approved?’,
 with a question mark).  Summaries are created for the ‘Time_Estimate’
 column by adding time duration expressions like HH:MM, and for the
 ‘Approved’ column, by providing an ‘[X]’ status if all children have
 been checked.  The ‘CLOCKSUM’ and ‘CLOCKSUM_T’ columns are special, they
 lists the sums of CLOCK intervals in the subtree, either for all clocks
 or just for today.
 
    ---------- Footnotes ----------
 
    (1) If more than one summary type applies to the same property, the
 parent values are computed according to the first of them.
 
    (2) An age can be defined as a duration, using units defined in
 ‘org-duration-units’, e.g., ‘3d 1h’.  If any value in the column is as
 such, the summary is also expressed as a duration.
 
    (3) Please note that the ‘COLUMNS’ definition must be on a single
 line; it is wrapped here only because of formatting constraints.

 7.5.2 Using column view
 -----------------------
 
 Turning column view on or off
 .............................
 
 ‘C-c C-x C-c’ (‘org-columns’)
      Turn on column view.  If point is before the first headline in the
      file, column view is turned on for the entire file, using the
      ‘#+COLUMNS’ definition.  If point is somewhere inside the outline,
      this command searches the hierarchy, up from point, for a ‘COLUMNS’
      property that defines a format.  When one is found, the column view
      table is established for the tree starting at the entry that
      contains the ‘COLUMNS’ property.  If no such property is found, the
      format is taken from the ‘#+COLUMNS’ line or from the variable
      ‘org-columns-default-format’, and column view is established for
      the current entry and its subtree.
 
 ‘r’ or ‘g’ on a columns view line (‘org-columns-redo’)
      Recreate the column view, to include recent changes made in the
      buffer.
 
 ‘C-c C-c’ or ‘q’ on a columns view line (‘org-columns-quit’)
      Exit column view.
 
 Editing values
 ..............
 
 ‘<LEFT>’, ‘<RIGHT>’, ‘<UP>’, ‘<DOWN>’
      Move through the column view from field to field.
 
 ‘1..9,0’
      Directly select the Nth allowed value, ‘0’ selects the 10th value.
 
 ‘n’ or ‘S-<RIGHT>’ (‘org-columns-next-allowed-value’)
 ‘p’ or ‘S-<LEFT>’ (‘org-columns-previous-allowed-value’)
      Switch to the next/previous allowed value of the field.  For this,
      you have to have specified allowed values for a property.
 
 ‘e’ (‘org-columns-edit-value’)
      Edit the property at point.  For the special properties, this
      invokes the same interface that you normally use to change that
      property.  For example, the tag completion or fast selection
      interface pops up when editing a ‘TAGS’ property.
 
 ‘C-c C-c’ (‘org-columns-toggle-or-columns-quit’)
      When there is a checkbox at point, toggle it.  Else exit column
      view.
 
 ‘v’ (‘org-columns-show-value’)
      View the full value of this property.  This is useful if the width
      of the column is smaller than that of the value.
 
 ‘a’ (‘org-columns-edit-allowed’)
      Edit the list of allowed values for this property.  If the list is
      found in the hierarchy, the modified values is stored there.  If no
      list is found, the new value is stored in the first entry that is
      part of the current column view.
 
 Modifying column view on-the-fly
 ................................
 
 ‘<’ (‘org-columns-narrow’)
 ‘>’ (‘org-columns-widen’)
      Make the column narrower/wider by one character.
 
 ‘S-M-<RIGHT>’ (‘org-columns-new’)
      Insert a new column, to the left of the current column.
 
 ‘S-M-<LEFT>’ (‘org-columns-delete’)
      Delete the current column.
 
 ‘M-<LEFT>’ (‘org-columns-move-left’)
      Move the current column left.
 
 ‘M-<RIGHT>’ (‘org-columns-move-right’)
      Move the current column right.
 
 ‘M-<UP>’ (‘org-columns-move-row-up’)
      Move the current row up.
 
 ‘M-<DOWN>’ (‘org-columns-move-row-down’)
      Move the current row down.

 7.5.3 Capturing column view
 ---------------------------
 
 Since column view is just an overlay over a buffer, it cannot be
 exported or printed directly.  If you want to capture a column view, use
 a ‘columnview’ dynamic block (see *note Dynamic Blocks::).  The frame of
 this block looks like this:
 
      * The column view
      #+BEGIN: columnview :hlines 1 :id "label"
 
      #+END:
 
    This dynamic block has the following parameters:
 
 ‘:id’
      This is the most important parameter.  Column view is a feature
      that is often localized to a certain (sub)tree, and the capture
      block might be at a different location in the file.  To identify
      the tree whose view to capture, you can use four values:
 
      ‘local’
           Use the tree in which the capture block is located.
 
      ‘global’
           Make a global view, including all headings in the file.
 
      ‘file:FILENAME’
           Run column view at the top of the FILENAME file.
 
      ‘LABEL’
           Call column view in the tree that has an ‘ID’ property with
           the value LABEL.  You can use ‘M-x org-id-copy’ to create a
           globally unique ID for the current entry and copy it to the
           kill-ring.
 
 ‘:match’
      When set to a string, use this as a tags/property match filter to
      select only a subset of the headlines in the scope set by the ‘:id’
      parameter.
 
 ‘:hlines’
      When ‘t’, insert an hline after every line.  When a number N,
      insert an hline before each headline with level ‘<= N’.
 
 ‘:vlines’
      When non-‘nil’, force column groups to get vertical lines.
 
 ‘:maxlevel’
      When set to a number, do not capture entries below this level.
 
 ‘:skip-empty-rows’
      When non-‘nil’, skip rows where the only non-empty specifier of the
      column view is ‘ITEM’.
 
 ‘:exclude-tags’
      List of tags to exclude from column view table: entries with these
      tags will be excluded from the column view.
 
 ‘:indent’
      When non-‘nil’, indent each ‘ITEM’ field according to its level.
 
 ‘:link’
      When non-‘nil’, link the ‘ITEM’ headlines in the table to their
      origins.
 
 ‘:format’
      Specify a column attribute (see *note Column attributes::) for the
      dynamic block.
 
 ‘:formatter’
      A function to format column view data and insert it into the
      buffer.  See the option ‘org-columns-dblock-formatter’.
 
    The following commands insert or update the dynamic block:
 
 ‘org-columns-insert-dblock’
      Insert a dynamic block capturing a column view.  Prompt for the
      scope or ID of the view.
 
      This command can be invoked by calling
      ‘org-dynamic-block-insert-dblock’ (‘C-c C-x x’) and selecting
      “columnview” (see *note Dynamic Blocks::).
 
 ‘C-c C-c’ ‘C-c C-x C-u’ (‘org-dblock-update’)
      Update dynamic block at point.  Point needs to be on the ‘#+BEGIN’
      line of the dynamic block.
 
 ‘C-u C-c C-x C-u’ (‘org-update-all-dblocks’)
      Update all dynamic blocks (see *note Dynamic Blocks::).  This is
      useful if you have several clock table blocks, column-capturing
      blocks or other dynamic blocks in a buffer.
 
    You can add formulas to the column view table and you may add
 plotting instructions in front of the table—these survive an update of
 the block.  If there is a ‘TBLFM’ keyword after the table, the table is
 recalculated automatically after an update.
 
    An alternative way to capture and process property values into a
 table is provided by Eric Schulte’s ‘org-collector.el’, which is a
 package in ‘org-contrib’(1).  It provides a general API to collect
 properties from entries in a certain scope, and arbitrary Lisp
 expressions to process these values before inserting them into a table
 or a dynamic block.

 8 Dates and Times
 *****************
 
 To assist project planning, TODO items can be labeled with a date and/or
 a time.  The specially formatted string carrying the date and time
 information is called a _timestamp_ in Org mode.  This may be a little
 confusing because timestamp is often used as indicating when something
 was created or last changed.  However, in Org mode this term is used in
 a much wider sense.
 
    Timestamps can be used to plan appointments, schedule tasks, set
 deadlines, track time, and more.  The following sections describe the
 timestamp format and tooling that Org mode provides for common use cases
 dealing with time and time intervals.

 8.1 Timestamps
 ==============
 
 A timestamp is a specification of a date—possibly with a time or time
 range—in a special format, either ‘<2003-09-16 Tue>’ or ‘<2003-09-16 Tue
 09:39>’ or ‘<2003-09-16 Tue 12:00-12:30>’(1).  A timestamp can appear
 anywhere in the headline or body of an Org tree entry.  Its presence
 causes entries to be shown on specific dates in the agenda (see *note
 Weekly/daily agenda::).  We distinguish:
 
 Plain timestamp; Event; Appointment
      A simple timestamp just assigns a date/time to an item.  This is
      just like writing down an appointment or event in a paper agenda.
      In the agenda display, the headline of an entry associated with a
      plain timestamp is shown exactly on that date.  There can be
      multiple timestamps in an item.
 
           * Meet Peter at the movies
             <2006-11-01 Wed 19:15>
           * Discussion on climate change
             <2006-11-02 Thu 10:00-12:00>
           * My days off
             <2006-11-03 Fri>
             <2006-11-06 Mon>
 
 Timestamp with repeater interval
      A timestamp may contain a _repeater interval_, indicating that it
      applies not only on the given date, but again and again after a
      certain interval of N hours (h), days (d), weeks (w), months (m),
      or years (y).  The following shows up in the agenda every
      Wednesday:
 
           * Pick up Sam at school
             <2007-05-16 Wed 12:30 +1w>
 
 Diary-style expression entries
 
      For more complex date specifications, Org mode supports using the
      special expression diary entries implemented in the *note Emacs
      Calendar package: (emacs)Special Diary Entries.(2).  For example,
      with optional time:
 
           * 22:00-23:00 The nerd meeting on every 2nd Thursday of the month
             <%%(diary-float t 4 2) 22:00-23:00>
 
 Time range
 
      Time range is a timestamp having two time units connected by ‘-’
 
           * Discussion on climate change
              <2006-11-02 Thu 10:00-12:00>
 
 Time/Date range
      Two timestamps connected by ‘--’ denote a range.  In the agenda,
      the headline is shown on the first and last day of the range, and
      on any dates that are displayed and fall in the range.  The first
      example specifies just the dates of the range while the second
      example specifies a time range for each date.
 
           ** Meeting in Amsterdam
              <2004-08-23 Mon>--<2004-08-26 Thu>
           ** This weeks committee meetings
              <2004-08-23 Mon 10:00-11:00>--<2004-08-26 Thu 10:00-11:00>
 
 Inactive timestamp
      Just like a plain timestamp, but with square brackets instead of
      angular ones.  These timestamps are inactive in the sense that they
      do _not_ trigger an entry to show up in the agenda.
 
           * Gillian comes late for the fifth time
             [2006-11-01 Wed]
 
    ---------- Footnotes ----------
 
    (1) The Org date format is inspired by the standard ISO 8601
 date/time format.  To use an alternative format, see *note Custom time
 format::.  The day name is optional when you type the date yourself.
 However, any date inserted or modified by Org adds that day name, for
 reading convenience.
 
    (2) When working with the standard diary expression functions, you
 need to be very careful with the order of the arguments.  That order
 depends evilly on the variable ‘calendar-date-style’.  For example, to
 specify a date December 1, 2005, the call might look like ‘(diary-date
 12 1 2005)’ or ‘(diary-date 1 12 2005)’ or ‘(diary-date 2005 12 1)’,
 depending on the settings.  This has been the source of much confusion.
 Org mode users can resort to special versions of these functions, namely
 ‘org-date’, ‘org-anniversary’, ‘org-cyclic’, and ‘org-block’.  These
 work just like the corresponding ‘diary-’ functions, but with stable ISO
 order of arguments (year, month, day) wherever applicable, independent
 of the value of ‘calendar-date-style’.

 8.2 Creating Timestamps
 =======================
 
 For Org mode to recognize timestamps, they need to be in the specific
 format.  All commands listed below produce timestamps in the correct
 format.
 
 ‘C-c .’ (‘org-timestamp’)
      Prompt for a date and insert a corresponding timestamp.  When point
      is at an existing timestamp in the buffer, the command is used to
      modify this timestamp instead of inserting a new one.  When this
      command is used twice in succession, a time range is inserted.
 
      When called with a prefix argument, use the alternative format
      which contains date and time.  The default time can be rounded to
      multiples of 5 minutes.  See the option
      ‘org-timestamp-rounding-minutes’.
 
      With two prefix arguments, insert an active timestamp with the
      current time without prompting.
 
 ‘C-c !’ (‘org-timestamp-inactive’)
      Like ‘C-c .’, but insert an inactive timestamp that does not cause
      an agenda entry.
 
 ‘C-c C-c’
      Normalize timestamp, insert or fix day name if missing or wrong.
 
 ‘C-c <’ (‘org-date-from-calendar’)
      Insert a timestamp corresponding to point date in the calendar.
 
 ‘C-c >’ (‘org-goto-calendar’)
      Access the Emacs calendar for the current date.  If there is a
      timestamp in the current line, go to the corresponding date
      instead.
 
 ‘C-c C-o’ (‘org-open-at-point’)
      Access the agenda for the date given by the timestamp or -range at
      point (see *note Weekly/daily agenda::).
 
 ‘S-<LEFT>’ (‘org-timestamp-down-day’)
 ‘S-<RIGHT>’ (‘org-timestamp-up-day’)
      Change date at point by one day.  These key bindings conflict with
      shift-selection and related modes (see *note Conflicts::).
 
 ‘S-<UP>’ (‘org-timestamp-up’)
 ‘S-<DOWN>’ (‘org-timestamp-down’)
      On the beginning or enclosing bracket of a timestamp, change its
      type.  Within a timestamp, change the item under point.  Point can
      be on a year, month, day, hour or minute.  When the timestamp
      contains a time range like ‘15:30-16:30’, modifying the first time
      also shifts the second, shifting the time block with constant
      length.  To change the length, modify the second time.  Note that
      if point is in a headline and not at a timestamp, these same keys
      modify the priority of an item (see *note Priorities::).  The key
      bindings also conflict with shift-selection and related modes (see
      *note Conflicts::).
 
 ‘C-c C-y’ (‘org-evaluate-time-range’)
      Evaluate a time range by computing the difference between start and
      end.  With a prefix argument, insert result after the time range
      (in a table: into the following column).

 * Custom time format::           Making dates look different.
 
 
 File: org.info,  Node: The date/time prompt,  Next: Custom time format,  Up: Creating Timestamps
 
 8.2.1 The date/time prompt
 --------------------------
 
 When Org mode prompts for a date/time, the default is shown in default
 date/time format, and the prompt therefore seems to ask for a specific
 format.  But it in fact accepts date/time information in a variety of
 formats.  Generally, the information should start at the beginning of
 the string.  Org mode finds whatever information is in there and derives
 anything you have not specified from the _default date and time_.  The
 default is usually the current date and time, but when modifying an
 existing timestamp, or when entering the second stamp of a range, it is
 taken from the stamp in the buffer.  When filling in information, Org
 mode assumes that most of the time you want to enter a date in the
 future: if you omit the month/year and the given day/month is _before_
 today, it assumes that you mean a future date(1).  If the date has been
 automatically shifted into the future, the time prompt shows this with
 ‘(=>F)’.
 
    For example, let’s assume that today is *June 13, 2006*.  Here is how
 various inputs are interpreted, the items filled in by Org mode are in
 *bold*.
 
 ‘3-2-5’          ⇒ 2003-02-05
 ‘2/5/3’          ⇒ 2003-02-05
 ‘14’             ⇒ *2006*-*06*-14
 ‘12’             ⇒ *2006*-*07*-12
 ‘2/5’            ⇒ *2007*-02-05
 ‘Fri’            ⇒ nearest Friday (default date or later)
 ‘sep 15’         ⇒ *2006*-09-15
 ‘feb 15’         ⇒ *2007*-02-15
 ‘sep 12 9’       ⇒ 2009-09-12
 ‘12:45’          ⇒ *2006*-*06*-*13* 12:45
 ‘22 sept 0:34’   ⇒ *2006*-09-22 0:34
 ‘w4’             ⇒ ISO week for of the current year *2006*
 ‘2012 w4 fri’    ⇒ Friday of ISO week 4 in 2012
 ‘2012-w04-5’     ⇒ Same as above
 
    Furthermore you can specify a relative date by giving, as the _first_
 thing in the input: a plus/minus sign, a number and a letter—‘h’, ‘d’,
 ‘w’, ‘m’ or ‘y’—to indicate a change in hours, days, weeks, months, or
 years.  With ‘h’ the date is relative to the current time, with the
 other letters and a single plus or minus, the date is relative to today
 at 00:00.  With a double plus or minus, it is relative to the default
 date.  If instead of a single letter, you use the abbreviation of day
 name, the date is the Nth such day, e.g.:
 
 ‘+0’      ⇒ today
 ‘.’       ⇒ today
 ‘+2h’     ⇒ two hours from now
 ‘+4d’     ⇒ four days from today
 ‘+4’      ⇒ same as +4d
 ‘+2w’     ⇒ two weeks from today
 ‘++5’     ⇒ five days from default date
 ‘+2tue’   ⇒ second Tuesday from now
 
    The function understands English month and weekday abbreviations.  If
 you want to use un-abbreviated names and/or other languages, configure
 the variables ‘parse-time-months’ and ‘parse-time-weekdays’.
 
    Not all dates can be represented in a given Emacs implementation.  By
 default Org mode forces dates into the compatibility range 1970–2037
 which works on all Emacs implementations.  If you want to use dates
 outside of this range, read the docstring of the variable
 ‘org-read-date-force-compatible-dates’.
 
    You can specify a time range by giving start and end times or by
 giving a start time and a duration (in HH:MM format).  Use one or two
 dash(es) as the separator in the former case and use ‘+’ as the
 separator in the latter case, e.g.:
 
 ‘11am-1:15pm’    ⇒ 11:00-13:15
 ‘11h-13h15’      ⇒ same as above
 ‘11am--1:15pm’   ⇒ same as above
 ‘11am+2:15’      ⇒ same as above
 
    Parallel to the minibuffer prompt, a calendar is popped up(2).  When
 you exit the date prompt, either by clicking on a date in the calendar,
 or by pressing ‘<RET>’, the date selected in the calendar is combined
 with the information entered at the prompt.  You can control the
 calendar fully from the minibuffer:
 
 ‘<RET>’            Choose date at point in calendar.
 ‘mouse-1’          Select date by clicking on it.
 ‘S-<RIGHT>’        One day forward.
 ‘S-<LEFT>’         One day backward.
 ‘S-<DOWN>’         One week forward.
 ‘S-<UP>’           One week backward.
 ‘M-S-<RIGHT>’      One month forward.
 ‘M-S-<LEFT>’       One month backward.
 ‘>’                Scroll calendar forward by one month.
 ‘<’                Scroll calendar backward by one month.
 ‘M-v’              Scroll calendar forward by 3 months.
 ‘C-v’              Scroll calendar backward by 3 months.
 ‘C-.’              Select today’s date(3)
 
    The actions of the date/time prompt may seem complex, but I assure
 you they will grow on you, and you will start getting annoyed by pretty
 much any other way of entering a date/time out there.  To help you
 understand what is going on, the current interpretation of your input is
 displayed live in the minibuffer(4).
 
    ---------- Footnotes ----------
 
    (1) See the variable ‘org-read-date-prefer-future’.  You may set that
 variable to the symbol ‘time’ to even make a time before now shift the
 date to tomorrow.
 
    (2) If you do not need/want the calendar, configure the variable
 ‘org-popup-calendar-for-date-prompt’.
 
    (3) You can also use the calendar command ‘.’ to jump to today’s
 date, but if you are inserting an hour specification for your timestamp,
 ‘.’ will then insert a dot after the hour.  By contrast, ‘C-.’ will
 always jump to today’s date.
 
    (4) If you find this distracting, turn off the display with
 ‘org-read-date-display-live’.
 
 
 File: org.info,  Node: Custom time format,  Prev: The date/time prompt,  Up: Creating Timestamps
 
 8.2.2 Custom time format
 ------------------------
 
 Org mode uses the standard ISO notation for dates and times as it is
 defined in ISO 8601.  If you cannot get used to this and require another
 representation of date and time to keep you happy, you can get it by
 customizing the variables ‘org-display-custom-times’ and
 ‘org-timestamp-custom-formats’.
 
 ‘C-c C-x C-t’ (‘org-toggle-timestamp-overlays’)
      Toggle the display of custom formats for dates and times.
 
    Org mode needs the default format for scanning, so the custom
 date/time format does not _replace_ the default format.  Instead, it is
 put _over_ the default format using text properties.  This has the
 following consequences:
 
    • You cannot place point onto a timestamp anymore, only before or
      after.
 
    • The ‘S-<UP>’ and ‘S-<DOWN>’ keys can no longer be used to adjust
      each component of a timestamp.  If point is at the beginning of the
      stamp, ‘S-<UP>’ and ‘S-<DOWN>’ change the stamp by one day, just
      like ‘S-<LEFT>’ ‘S-<RIGHT>’.  At the end of the stamp, change the
      time by one minute.
 
    • If the timestamp contains a range of clock times or a repeater,
      these are not overlaid, but remain in the buffer as they were.
 
    • When you delete a timestamp character-by-character, it only
      disappears from the buffer after _all_ (invisible) characters
      belonging to the ISO timestamp have been removed.
 
    • If the custom timestamp format is longer than the default and you
      are using dates in tables, table alignment will be messed up.  If
      the custom format is shorter, things do work as expected.

 8.3 Deadlines and Scheduling
 ============================
 
 A timestamp may be preceded by special keywords to facilitate planning.
 Both the timestamp and the keyword have to be positioned immediately
 after the task they refer to.
 
 ‘DEADLINE’
      Meaning: the task—most likely a TODO item, though not
      necessarily—is supposed to be finished on that date.
 
      On the deadline date, the task is listed in the agenda.  In
      addition, the agenda for _today_ carries a warning about the
      approaching or missed deadline, starting
      ‘org-deadline-warning-days’ before the due date, and continuing
      until the entry is marked as done.  An example:
 
           *** TODO write article about the Earth for the Guide
               DEADLINE: <2004-02-29 Sun>
               The editor in charge is [[bbdb:Ford Prefect]]
 
      You can specify a different lead time for warnings for a specific
      deadlines using the following syntax.  Here is an example with a
      warning period of 5 days ‘DEADLINE: <2004-02-29 Sun -5d>’.  This
      warning is deactivated if the task gets scheduled and you set
      ‘org-agenda-skip-deadline-prewarning-if-scheduled’ to ‘t’.
 
 ‘SCHEDULED’
      Meaning: you are planning to start working on that task on the
      given date.
 
      The headline is listed under the given date(1).  In addition, a
      reminder that the scheduled date has passed is present in the
      compilation for _today_, until the entry is marked as done, i.e.,
      the task is automatically forwarded until completed.
 
           *** TODO Call Trillian for a date on New Years Eve.
               SCHEDULED: <2004-12-25 Sat>
 
      If you want to _delay_ the display of this task in the agenda, use
      ‘SCHEDULED: <2004-12-25 Sat -2d>’: the task is still scheduled on
      the 25th but will appear two days later.  In case the task contains
      a repeater, the delay is considered to affect all occurrences; if
      you want the delay to only affect the first scheduled occurrence of
      the task, use ‘--2d’ instead.  See ‘org-scheduled-delay-days’ and
      ‘org-agenda-skip-scheduled-delay-if-deadline’ for details on how to
      control this globally or per agenda.
 
           Important: Scheduling an item in Org mode should _not_ be
           understood in the same way that we understand _scheduling a
           meeting_.  Setting a date for a meeting is just a simple
           appointment, you should mark this entry with a simple plain
           timestamp, to get this item shown on the date where it
           applies.  This is a frequent misunderstanding by Org users.
           In Org mode, _scheduling_ means setting a date when you want
           to start working on an action item.
 
    You may use timestamps with repeaters in scheduling and deadline
 entries.  Org mode issues early and late warnings based on the
 assumption that the timestamp represents the _nearest instance_ of the
 repeater.  However, the use of diary expression entries like
 
      <%%(diary-float t 42)>
 
 in scheduling and deadline timestamps is limited.  Org mode does not
 know enough about the internals of each function to issue early and late
 warnings.  However, it shows the item on each day where the expression
 entry matches.

 File: org.info,  Node: Inserting deadline/schedule,  Next: Repeated tasks,  Up: Deadlines and Scheduling
 
 8.3.1 Inserting deadlines or schedules
 --------------------------------------
 
 The following commands allow you to quickly insert a deadline or to
 schedule an item:(1)
 
 ‘C-c C-d’ (‘org-deadline’)
      Insert ‘DEADLINE’ keyword along with a stamp.  The insertion
      happens in the line directly following the headline.  Remove any
      ‘CLOSED’ timestamp .  When called with a prefix argument, also
      remove any existing deadline from the entry.  Depending on the
      variable ‘org-log-redeadline’, take a note when changing an
      existing deadline(2).
 
 ‘C-c C-s’ (‘org-schedule’)
      Insert ‘SCHEDULED’ keyword along with a stamp.  The insertion
      happens in the line directly following the headline.  Remove any
      ‘CLOSED’ timestamp.  When called with a prefix argument, also
      remove the scheduling date from the entry.  Depending on the
      variable ‘org-log-reschedule’, take a note when changing an
      existing scheduling time(3).
 
 ‘C-c / d’ (‘org-check-deadlines’)
      Create a sparse tree with all deadlines that are either past-due,
      or which will become due within ‘org-deadline-warning-days’.  With
      ‘C-u’ prefix, show all deadlines in the file.  With a numeric
      prefix, check that many days.  For example, ‘C-1 C-c / d’ shows all
      deadlines due tomorrow.
 
 ‘C-c / b’ (‘org-check-before-date’)
      Sparse tree for deadlines and scheduled items before a given date.
 
 ‘C-c / a’ (‘org-check-after-date’)
      Sparse tree for deadlines and scheduled items after a given date.
 
    Note that ‘org-schedule’ and ‘org-deadline’ supports setting the date
 by indicating a relative time e.g., ‘+1d’ sets the date to the next day
 after today, and ‘--1w’ sets the date to the previous week before any
 current timestamp.
 
    ---------- Footnotes ----------
 
    (1) The ‘SCHEDULED’ and ‘DEADLINE’ dates are inserted on the line
 right below the headline.  Do not put any text between this line and the
 headline.
 
    (2) Note the corresponding ‘STARTUP’ options ‘logredeadline’,
 ‘lognoteredeadline’, and ‘nologredeadline’.
 
    (3) Note the corresponding ‘STARTUP’ options ‘logreschedule’,
 ‘lognotereschedule’, and ‘nologreschedule’.
 
 
 File: org.info,  Node: Repeated tasks,  Prev: Inserting deadline/schedule,  Up: Deadlines and Scheduling
 
 8.3.2 Repeated tasks
 --------------------
 
 Some tasks need to be repeated again and again.  Org mode helps to
 organize such tasks using a so-called repeater in a ‘DEADLINE’,
 ‘SCHEDULED’, or plain timestamps(1).  In the following example:
 
      ** TODO Pay the rent
         DEADLINE: <2005-10-01 Sat +1m>
 
 the ‘+1m’ is a repeater; the intended interpretation is that the task
 has a deadline on ‘<2005-10-01>’ and repeats itself every (one) month
 starting from that time.  You can use yearly, monthly, weekly, daily and
 hourly repeat cookies by using the ‘y’, ‘m’, ‘w’, ‘d’ and ‘h’ letters.
 If you need both a repeater and a special warning period in a deadline
 entry, the repeater should come first and the warning period last
 
      DEADLINE: <2005-10-01 Sat +1m -3d>
 
    Deadlines and scheduled items produce entries in the agenda when they
 are over-due, so it is important to be able to mark such an entry as
 done once you have done so.  When you mark a ‘DEADLINE’ or a ‘SCHEDULED’
 with the TODO keyword ‘DONE’, it no longer produces entries in the
 agenda.  The problem with this is, however, is that then also the _next_
 instance of the repeated entry will not be active.  Org mode deals with
 this in the following way: when you try to mark such an entry as done,
 using ‘C-c C-t’, it shifts the base date of the repeating timestamp by
 the repeater interval, and immediately sets the entry state back to
 TODO(2). In the example above, setting the state to ‘DONE’ would
 actually switch the date like this:
 
      ** TODO Pay the rent
         DEADLINE: <2005-11-01 Tue +1m>
 
    When task contains multiple timestamps with repeater interval, all
 these timestamps are shifted.
 
    To mark a task with a repeater as DONE, use ‘C-- 1 C-c C-t’, i.e.,
 ‘org-todo’ with a numeric prefix argument of ‘-1’.
 
    A timestamp(3) is added under the deadline, to keep a record that you
 actually acted on the previous instance of this deadline.
 
    As a consequence of shifting the base date, this entry is no longer
 visible in the agenda when checking past dates, but all future instances
 will be visible.
 
    With the ‘+1m’ cookie, the date shift is always exactly one month.
 So if you have not paid the rent for three months, marking this entry
 DONE still keeps it as an overdue deadline.  Depending on the task, this
 may not be the best way to handle it.  For example, if you forgot to
 call your father for 3 weeks, it does not make sense to call him 3 times
 in a single day to make up for it.  Finally, there are tasks, like
 changing batteries, which should always repeat a certain time _after_
 the last time you did it.  For these tasks, Org mode has special
 repeaters ‘++’ and ‘.+’.  For example:
 
      ** TODO Call Father
         DEADLINE: <2008-02-10 Sun ++1w>
         Marking this DONE shifts the date by at least one week, but also
         by as many weeks as it takes to get this date into the future.
         However, it stays on a Sunday, even if you called and marked it
         done on Saturday.
 
      ** TODO Empty kitchen trash
         DEADLINE: <2008-02-08 Fri 20:00 ++1d>
         Marking this DONE shifts the date by at least one day, and also
         by as many days as it takes to get the timestamp into the future.
         Since there is a time in the timestamp, the next deadline in the
         future will be on today's date if you complete the task before
         20:00.
 
      ** TODO Check the batteries in the smoke detectors
         DEADLINE: <2005-11-01 Tue .+1m>
         Marking this DONE shifts the date to one month after today.
 
      ** TODO Wash my hands
         DEADLINE: <2019-04-05 08:00 Fri .+1h>
         Marking this DONE shifts the date to exactly one hour from now.
 
    You may have both scheduling and deadline information for a specific
 task.  If the repeater is set for the scheduling information only, you
 probably want the repeater to be ignored after the deadline.  If so, set
 the variable ‘org-agenda-skip-scheduled-repeats-after-deadline’ to ‘t’.
 However, any scheduling information without a repeater is no longer
 relevant once the task is done, and thus, removed upon repeating the
 task.  If you want both scheduling and deadline information to repeat
 after the same interval, set the same repeater for both timestamps.
 
    An alternative to using a repeater is to create a number of copies of
 a task subtree, with dates shifted in each copy.  The command ‘C-c C-x
 c’ was created for this purpose; it is described in *note Structure
 Editing::.
 
    ---------- Footnotes ----------
 
    (1) Org does not repeat inactive timestamps, however.  See *note
 Timestamps::.
 
    (2) In fact, the target state is taken from, in this sequence, the
 ‘REPEAT_TO_STATE’ property, the variable ‘org-todo-repeat-to-state’ if
 it is a string, the previous TODO state if ‘org-todo-repeat-to-state’ is
 ‘t’, or the first state of the TODO state sequence.
 
    (3) You can change this using the option ‘org-log-repeat’, or the
 ‘STARTUP’ options ‘logrepeat’, ‘lognoterepeat’, and ‘nologrepeat’.  With
 ‘lognoterepeat’, you will also be prompted for a note.

 8.4 Clocking Work Time
 ======================
 
 Org mode allows you to clock the time you spend on specific tasks in a
 project.  When you start working on an item, you can start the clock.
 When you stop working on that task, or when you mark the task done, the
 clock is stopped and the corresponding time interval is recorded.  It
 also computes the total time spent on each subtree(1) of a project.  And
 it remembers a history or tasks recently clocked, so that you can jump
 quickly between a number of tasks absorbing your time.
 
    To save the clock history across Emacs sessions, use:
 
      (setq org-clock-persist 'history)
      (org-clock-persistence-insinuate)
 
    When you clock into a new task after resuming Emacs, the incomplete
 clock(2) is retrieved (see *note Resolving idle time (1)::) and you are
 prompted about what to do with it.
 
 * Menu:
 
 * Clocking commands::            Starting and stopping a clock.
 * The clock table::              Detailed reports.
 * Resolving idle time::          Resolving time when you’ve been idle.
 
    ---------- Footnotes ----------
 
    (1) Clocking only works if all headings are indented with less than
 30 stars.  This is a hard-coded limitation of ‘lmax’ in ‘org-clock-sum’.
 
    (2) To resume the clock under the assumption that you have worked on
 this task while outside Emacs, use ‘(setq org-clock-persist t)’.
 
 
 File: org.info,  Node: Clocking commands,  Next: The clock table,  Up: Clocking Work Time
 
 8.4.1 Clocking commands
 -----------------------
 
 ‘C-c C-x C-i’ (‘org-clock-in’)
      Start the clock on the current item (clock-in).  This inserts the
      ‘CLOCK’ keyword together with a timestamp.  If this is not the
      first clocking of this item, the multiple ‘CLOCK’ lines are wrapped
      into a ‘LOGBOOK’ drawer (see also the variable
      ‘org-clock-into-drawer’).  You can also overrule the setting of
      this variable for a subtree by setting a ‘CLOCK_INTO_DRAWER’ or
      ‘LOG_INTO_DRAWER’ property.  When called with a ‘C-u’ prefix
      argument, select the task from a list of recently clocked tasks.
      With two ‘C-u C-u’ prefixes, clock into the task at point and mark
      it as the default task; the default task is always be available
      with letter ‘d’ when selecting a clocking task.  With three ‘C-u
      C-u C-u’ prefixes, force continuous clocking by starting the clock
      when the last clock stopped.
 
      While the clock is running, Org shows the current clocking time in
      the mode line, along with the title of the task.  The clock time
      shown is all time ever clocked for this task and its children.  If
      the task has an effort estimate (see *note Effort Estimates::), the
      mode line displays the current clocking time against it(1).  If the
      task is a repeating one (see *note Repeated tasks::), show only the
      time since the last reset of the task(2).  You can exercise more
      control over show time with the ‘CLOCK_MODELINE_TOTAL’ property.
      It may have the values ‘current’ to show only the current clocking
      instance, ‘today’ to show all time clocked on this tasks today—see
      also the variable ‘org-extend-today-until’, ‘all’ to include all
      time, or ‘auto’ which is the default(3).  Clicking with ‘mouse-1’
      onto the mode line entry pops up a menu with clocking options.
 
 ‘C-c C-x C-o’ (‘org-clock-out’)
      Stop the clock (clock-out).  This inserts another timestamp at the
      same location where the clock was last started.  It also directly
      computes the resulting time in inserts it after the time range as
      ‘=>HH:MM’.  See the variable ‘org-log-note-clock-out’ for the
      possibility to record an additional note together with the
      clock-out timestamp(4).
 
 ‘C-c C-x C-x’ (‘org-clock-in-last’)
      Re-clock the last clocked task.  With one ‘C-u’ prefix argument,
      select the task from the clock history.  With two ‘C-u’ prefixes,
      force continuous clocking by starting the clock when the last clock
      stopped.
 
 ‘C-c C-x C-e’ (‘org-clock-modify-effort-estimate’)
      Update the effort estimate for the current clock task.
 
 ‘C-c C-c’ or ‘C-c C-y’ (‘org-evaluate-time-range’)
      Recompute the time interval after changing one of the timestamps.
      This is only necessary if you edit the timestamps directly.  If you
      change them with ‘S-<cursor>’ keys, the update is automatic.
 
 ‘C-S-<UP>’ (‘org-clock-timestamps-up’)
 ‘C-S-<DOWN>’ (‘org-clock-timestamps-down’)
      On CLOCK log lines, increase/decrease both timestamps so that the
      clock duration keeps the same value.
 
 ‘S-M-<UP>’ (‘org-timestamp-up’)
 ‘S-M-<DOWN>’ (‘org-timestamp-down’)
      On ‘CLOCK’ log lines, increase/decrease the timestamp at point and
      the one of the previous, or the next, clock timestamp by the same
      duration.  For example, if you hit ‘S-M-<UP>’ to increase a
      clocked-out timestamp by five minutes, then the clocked-in
      timestamp of the next clock is increased by five minutes.
 
      Only ‘CLOCK’ logs created during current Emacs session are
      considered when adjusting next/previous timestamp.
 
 ‘C-c C-t’ (‘org-todo’)
      Changing the TODO state of an item to DONE automatically stops the
      clock if it is running in this same item.
 
 ‘C-c C-x C-q’ (‘org-clock-cancel’)
      Cancel the current clock.  This is useful if a clock was started by
      mistake, or if you ended up working on something else.
 
 ‘C-c C-x C-j’ (‘org-clock-goto’)
      Jump to the headline of the currently clocked in task.  With a
      ‘C-u’ prefix argument, select the target task from a list of
      recently clocked tasks.
 
 ‘C-c C-x C-d’ (‘org-clock-display’)
      Display time summaries for each subtree in the current buffer.
      This puts overlays at the end of each headline, showing the total
      time recorded under that heading, including the time of any
      subheadings.  You can use visibility cycling to study the tree, but
      the overlays disappear when you change the buffer (see variable
      ‘org-remove-highlights-with-change’) or press ‘C-c C-c’.
 
    The ‘l’ key may be used in the agenda (see *note Weekly/daily
 agenda::) to show which tasks have been worked on or closed during a
 day.
 
    *Important:* note that both ‘org-clock-out’ and ‘org-clock-in-last’
 can have a global keybinding and do not modify the window disposition.
 
    ---------- Footnotes ----------
 
    (1) To add an effort estimate “on the fly”, hook a function doing
 this to ‘org-clock-in-prepare-hook’.
 
    (2) The last reset of the task is recorded by the ‘LAST_REPEAT’
 property.
 
    (3) See also the variable ‘org-clock-mode-line-total’.
 
    (4) The corresponding in-buffer setting is: ‘#+STARTUP:
 lognoteclock-out’.

 8.4.2 The clock table
 ---------------------
 
 Org mode can produce quite complex reports based on the time clocking
 information.  Such a report is called a _clock table_, because it is
 formatted as one or several Org tables.
 
 ‘org-clock-report’
      Insert or update a clock table.  When called with a prefix
      argument, jump to the first clock table in the current document and
      update it.  The clock table includes archived trees.
 
      This command can be invoked by calling
      ‘org-dynamic-block-insert-dblock’ (‘C-c C-x x’) and selecting
      “clocktable” (see *note Dynamic Blocks::).
 
 ‘C-c C-c’ or ‘C-c C-x C-u’ (‘org-dblock-update’)
      Update dynamic block at point.  Point needs to be in the ‘BEGIN’
      line of the dynamic block.
 
 ‘C-u C-c C-x C-u’
      Update all dynamic blocks (see *note Dynamic Blocks::).  This is
      useful if you have several clock table blocks in a buffer.
 
 ‘S-<LEFT>’
 ‘S-<RIGHT>’ (‘org-clocktable-try-shift’)
      Shift the current ‘:block’ interval and update the table.  Point
      needs to be in the ‘#+BEGIN: clocktable’ line for this command.  If
      ‘:block’ is ‘today’, it is shifted to ‘today-1’, etc.
 
    Here is an example of the frame for a clock table as it is inserted
 into the buffer by ‘org-clock-report’:
 
      #+BEGIN: clocktable :maxlevel 2 :emphasize nil :scope file
      #+END:
 
    The ‘#+BEGIN’ line contains options to define the scope, structure,
 and formatting of the report.  Defaults for all these options can be
 configured in the variable ‘org-clocktable-defaults’.
 
    First there are options that determine which clock entries are to be
 selected:
 
 ‘:maxlevel’
      Maximum level depth to which times are listed in the table.  Clocks
      at deeper levels are summed into the upper level.
 
 ‘:scope’
      The scope to consider.  This can be any of the following:
 
      ‘nil’                    the current buffer or narrowed region
      ‘file’                   the full current buffer
      ‘subtree’                the subtree where the clocktable is located
      ‘treeN’                  the surrounding level N tree, for example ‘tree3’
      ‘tree’                   the surrounding level 1 tree
      ‘agenda’                 all agenda files
      ‘("file" ...)’           scan these files
      ‘FUNCTION’               scan files returned by calling FUNCTION with no argument
      ‘file-with-archives’     current file and its archives
      ‘agenda-with-archives’   all agenda files, including archives
 
 ‘:block’
      The time block to consider.  This block is specified either
      absolutely, or relative to the current time and may be any of these
      formats:
 
      ‘2007-12-31’                              New year eve 2007
      ‘2007-12’                                 December 2007
      ‘2007-W50’                                ISO-week 50 in 2007
      ‘2007-Q2’                                 2nd quarter in 2007
      ‘2007’                                    the year 2007
      ‘today’, ‘yesterday’, ‘today-N’           a relative day
      ‘thisweek’, ‘lastweek’, ‘thisweek-N’      a relative week
      ‘thismonth’, ‘lastmonth’, ‘thismonth-N’   a relative month
      ‘thisyear’, ‘lastyear’, ‘thisyear-N’      a relative year
      ‘untilnow’(1)                             all clocked time ever
 
      When this option is not set, Org falls back to the value in
      ‘org-clock-display-default-range’, which defaults to the current
      year.
 
      Use ‘S-<LEFT>’ or ‘S-<RIGHT>’ to shift the time interval.
 
 ‘:tstart’
      A time string specifying when to start considering times.  Relative
      times like ‘"<-2w>"’ can also be used.  See *note Matching tags and
      properties:: for relative time syntax.
 
 ‘:tend’
      A time string specifying when to stop considering times.  Relative
      times like ‘"<now>"’ can also be used.  See *note Matching tags and
      properties:: for relative time syntax.
 
 ‘:wstart’
      The starting day of the week.  The default is 1 for Monday.
 
 ‘:mstart’
      The starting day of the month.  The default is 1 for the first.
 
 ‘:step’
      Set to ‘day’, ‘week’, ‘semimonth’, ‘month’, ‘quarter’, or ‘year’ to
      split the table into chunks.  To use this, either ‘:block’, or
      ‘:tstart’ and ‘:tend’ are required.
 
 ‘:stepskip0’
      When non-‘nil’, do not show steps that have zero time.
 
 ‘:fileskip0’
      When non-‘nil’, do not show table sections from files which did not
      contribute.
 
 ‘:match’
      A tags match to select entries that should contribute.  See *note
      Matching tags and properties:: for the match syntax.
 
    Then there are options that determine the formatting of the table.
 There options are interpreted by the function
 ‘org-clocktable-write-default’, but you can specify your own function
 using the ‘:formatter’ parameter.
 
 ‘:emphasize’
      When non-‘nil’, emphasize level one and level two items.
 
 ‘:lang’
      Language(2) to use for descriptive cells like “Task”.
 
 ‘:link’
      Link the item headlines in the table to their origins.
 
 ‘:narrow’
      An integer to limit the width of the headline column in the Org
      table.  If you write it like ‘50!’, then the headline is also
      shortened in export.
 
 ‘:indent’
      Indent each headline field according to its level.
 
 ‘:filetitle’
      Show title in the file column if the file has a ‘#+title’.
 
 ‘:hidefiles’
      Hide the file column when multiple files are used to produce the
      table.
 
 ‘:tcolumns’
      Number of columns to be used for times.  If this is smaller than
      ‘:maxlevel’, lower levels are lumped into one column.
 
 ‘:level’
      Should a level number column be included?
 
 ‘:sort’
      A cons cell containing the column to sort and a sorting type.
      E.g., ‘:sort (1 . ?a)’ sorts the first column alphabetically.
 
 ‘:compact’
      Abbreviation for ‘:level nil :indent t :narrow 40! :tcolumns 1’.
      All are overwritten except if there is an explicit ‘:narrow’.
 
 ‘:timestamp’
      A timestamp for the entry, when available.  Look for ‘SCHEDULED’,
      ‘DEADLINE’, ‘TIMESTAMP’ and ‘TIMESTAMP_IA’ special properties (see
      *note Special Properties::), in this order.
 
 ‘:tags’
      When this flag is non-‘nil’, show the headline’s tags.
 
 ‘:properties’
      List of properties shown in the table.  Each property gets its own
      column.
 
 ‘:inherit-props’
      When this flag is non-‘nil’, the values for ‘:properties’ are
      inherited.
 
 ‘:formula’
      Content of a ‘TBLFM’ keyword to be added and evaluated.  As a
      special case, ‘:formula %’ adds a column with % time.  If you do
      not specify a formula here, any existing formula below the clock
      table survives updates and is evaluated.
 
 ‘:formatter’
      A function to format clock data and insert it into the buffer.
 
    To get a clock summary of the current level 1 tree, for the current
 day, you could write:
 
      #+BEGIN: clocktable :maxlevel 2 :block today :scope tree1 :link t
      #+END:
 
 To use a specific time range you could write(3)
 
      #+BEGIN: clocktable :tstart "<2006-08-10 Thu 10:00>"
                          :tend "<2006-08-10 Thu 12:00>"
      #+END:
 
 A range starting a week ago and ending right now could be written as
 
      #+BEGIN: clocktable :tstart "<-1w>" :tend "<now>"
      #+END:
 
 A summary of the current subtree with % times would be
 
      #+BEGIN: clocktable :scope subtree :link t :formula %
      #+END:
 
 A horizontally compact representation of everything clocked during last
 week would be
 
      #+BEGIN: clocktable :scope agenda :block lastweek :compact t
      #+END:
 
    ---------- Footnotes ----------
 
    (1) When using ‘:step’, ‘untilnow’ starts from the beginning of 2003,

 8.4.3 Resolving idle time and continuous clocking
 -------------------------------------------------
 
 Resolving idle time
 ...................
 
 If you clock in on a work item, and then walk away from your
 computer—perhaps to take a phone call—you often need to “resolve” the
 time you were away by either subtracting it from the current clock, or
 applying it to another one.
 
    By customizing the variable ‘org-clock-idle-time’ to some integer,
 such as 10 or 15, Emacs can alert you when you get back to your computer
 after being idle for that many minutes(1), and ask what you want to do
 with the idle time.  There will be a question waiting for you when you
 get back, indicating how much idle time has passed constantly updated
 with the current amount, as well as a set of choices to correct the
 discrepancy:
 
 ‘k’
      To keep some or all of the minutes and stay clocked in, press ‘k’.
      Org asks how many of the minutes to keep.  Press ‘<RET>’ to keep
      them all, effectively changing nothing, or enter a number to keep
      that many minutes.
 
 ‘K’
      If you use the shift key and press ‘K’, it keeps however many
      minutes you request and then immediately clock out of that task.
      If you keep all of the minutes, this is the same as just clocking
      out of the current task.
 
 ‘s’
      To keep none of the minutes, use ‘s’ to subtract all the away time
      from the clock, and then check back in from the moment you
      returned.
 
 ‘S’
      To keep none of the minutes and just clock out at the start of the
      away time, use the shift key and press ‘S’.  Remember that using
      shift always leave you clocked out, no matter which option you
      choose.
 
 ‘C’
      To cancel the clock altogether, use ‘C’.  Note that if instead of
      canceling you subtract the away time, and the resulting clock
      amount is less than a minute, the clock is still canceled rather
      than cluttering up the log with an empty entry.
 
    What if you subtracted those away minutes from the current clock, and
 now want to apply them to a new clock?  Simply clock in to any task
 immediately after the subtraction.  Org will notice that you have
 subtracted time “on the books”, so to speak, and will ask if you want to
 apply those minutes to the next task you clock in on.
 
    There is one other instance when this clock resolution magic occurs.
 Say you were clocked in and hacking away, and suddenly your cat chased a
 mouse who scared a hamster that crashed into your UPS’s power button!
 You suddenly lose all your buffers, but thanks to auto-save you still
 have your recent Org mode changes, including your last clock in.
 
    If you restart Emacs and clock into any task, Org will notice that
 you have a dangling clock which was never clocked out from your last
 session.  Using that clock’s starting time as the beginning of the
 unaccounted-for period, Org will ask how you want to resolve that time.
 The logic and behavior is identical to dealing with away time due to
 idleness; it is just happening due to a recovery event rather than a set
 amount of idle time.
 
    You can also check all the files visited by your Org agenda for
 dangling clocks at any time using ‘M-x org-resolve-clocks <RET>’ (or
 ‘C-c C-x C-z’).
 
 Continuous clocking
 ...................
 
 You may want to start clocking from the time when you clocked out the
 previous task.  To enable this systematically, set
 ‘org-clock-continuously’ to non-‘nil’.  Each time you clock in, Org
 retrieves the clock-out time of the last clocked entry for this session,
 and start the new clock from there.
 
    If you only want this from time to time, use three universal prefix
 arguments with ‘org-clock-in’ and two ‘C-u C-u’ with
 ‘org-clock-in-last’.
 
 Clocking out automatically after some idle time
 ...............................................
 
 When you often forget to clock out before being idle and you don’t want
 to manually set the clocking time to take into account, you can set
 ‘org-clock-auto-clockout-timer’ to a number of seconds and add
 ‘(org-clock-auto-clockout-insinuate)’ to your ‘.emacs’ file.
 
    When the clock is running and Emacs is idle for more than this number
 of seconds, the clock will be clocked out automatically.
 
    Use ‘M-x org-clock-toggle-auto-clockout RET’ to temporarily turn this
 on or off.
 
    ---------- Footnotes ----------
 
    (1) On computers using macOS, idleness is based on actual user
 idleness, not just Emacs’s idle time.  For X11, you can install a
 utility program ‘x11idle.c’, available in the ‘org-contrib/’ repository,
 or install the xprintidle package and set it to the variable
 ‘org-clock-x11idle-program-name’ if you are running Debian, to get the
 same general treatment of idleness.  On other systems, idle time refers
 to Emacs idle time only.

 8.5 Effort Estimates
 ====================
 
 If you want to plan your work in a very detailed way, or if you need to
 produce offers with quotations of the estimated work effort, you may
 want to assign effort estimates to entries.  If you are also clocking
 your work, you may later want to compare the planned effort with the
 actual working time, a great way to improve planning estimates.
 
    Effort estimates are stored in a special property ‘EFFORT’.  Multiple
 formats are supported, such as ‘3:12’, ‘1:23:45’, or ‘1d3h5min’; see the
 file ‘org-duration.el’ for more detailed information about the format.
 
    You can set the effort for an entry with the following commands:
 
 ‘C-c C-x e’ (‘org-set-effort’)
      Set the effort estimate for the current entry.  With a prefix
      argument, set it to the next allowed value—see below.  This command
      is also accessible from the agenda with the ‘e’ key.
 
 ‘C-c C-x C-e’ (‘org-clock-modify-effort-estimate’)
      Modify the effort estimate of the item currently being clocked.
 
    Clearly the best way to work with effort estimates is through column
 view (see *note Column View::).  You should start by setting up discrete
 values for effort estimates, and a ‘COLUMNS’ format that displays these
 values together with clock sums—if you want to clock your time.  For a
 specific buffer you can use:
 
      #+PROPERTY: Effort_ALL 0 0:10 0:30 1:00 2:00 3:00 4:00 5:00 6:00 7:00
      #+COLUMNS: %40ITEM(Task) %17Effort(Estimated Effort){:} %CLOCKSUM
 
 or, even better, you can set up these values globally by customizing the
 variables ‘org-global-properties’ and ‘org-columns-default-format’.  In
 particular if you want to use this setup also in the agenda, a global
 setup may be advised.
 
    The way to assign estimates to individual items is then to switch to
 column mode, and to use ‘S-<RIGHT>’ and ‘S-<LEFT>’ to change the value.
 The values you enter are immediately summed up in the hierarchy.  In the
 column next to it, any clocked time is displayed.
 
    If you switch to column view in the daily/weekly agenda, the effort
 column summarizes the estimated work effort for each day(1), and you can
 use this to find space in your schedule.  To get an overview of the
 entire part of the day that is committed, you can set the option
 ‘org-agenda-columns-add-appointments-to-effort-sum’.  The appointments
 on a day that take place over a specified time interval are then also
 added to the load estimate of the day.
 
    Effort estimates can be used in secondary agenda filtering that is
 triggered with the ‘/’ key in the agenda (see *note Agenda Commands::).
 If you have these estimates defined consistently, two or three key
 presses narrow down the list to stuff that fits into an available time
 slot.

 8.6 Taking Notes with a Relative Timer
 ======================================
 
 Org provides two types of timers.  There is a relative timer that counts
 up, which can be useful when taking notes during, for example, a meeting
 or a video viewing.  There is also a countdown timer.
 
    The relative and countdown are started with separate commands.
 
 ‘C-c C-x 0’ (‘org-timer-start’)
      Start or reset the relative timer.  By default, the timer is set to
      0.  When called with a ‘C-u’ prefix, prompt the user for a starting
      offset.  The prompt will default to a timer string at point (if
      any), providing a convenient way to restart taking notes after a
      break in the process.  When called with a double prefix argument
      ‘C-u C-u’, change all timer strings in the active region by a
      certain amount.  This can be used to fix timer strings if the timer
      was not started at exactly the right moment.
 
 ‘C-c C-x ;’ (‘org-timer-set-timer’)
      Start a countdown timer.  The user is prompted for a duration.
      ‘org-timer-default-timer’ sets the default countdown value.  Giving
      a numeric prefix argument overrides this default value.  This
      command is available as ‘;’ in agenda buffers.
 
    Once started, relative and countdown timers are controlled with the
 same commands.
 
 ‘C-c C-x .’ (‘org-timer’)
      Insert a relative time into the buffer.  The first time you use
      this, the timer starts.  Using a prefix argument restarts it.
 
 ‘C-c C-x -’ (‘org-timer-item’)
      Insert a description list item with the current relative time.
      With a prefix argument, first reset the timer to 0.
 
 ‘M-<RET>’ (‘org-insert-heading’)
      Once the timer list is started, you can also use ‘M-<RET>’ to
      insert new timer items.
 
 ‘C-c C-x ,’ (‘org-timer-pause-or-continue’)
      Pause the timer, or continue it if it is already paused.
 
 ‘C-c C-x _’ (‘org-timer-stop’)
      Stop the timer.  After this, you can only start a new timer, not
      continue the old one.  This command also removes the timer from the
      mode line.

 9 Refiling and Archiving
 ************************
 
 Once information is in the system, it may need to be moved around.  Org
 provides Refile, Copy and Archive commands for this.  Refile and Copy
 helps with moving and copying outlines.  Archiving helps to keep the
 system compact and fast.
 
 * Menu:
 
 * Refile and Copy::              Moving/copying a tree from one place to another.
 * Archiving::                    What to do with finished products.
 
 
 File: org.info,  Node: Refile and Copy,  Next: Archiving,  Up: Refiling and Archiving
 
 9.1 Refile and Copy
 ===================
 
 When reviewing the captured data, you may want to refile or to copy some
 of the entries into a different list, for example into a project.
 Cutting, finding the right location, and then pasting the note is
 cumbersome.  To simplify this process, you can use the following special
 command:
 
 ‘C-c C-w’ (‘org-refile’)
      Refile the entry or region at point.  This command offers possible
      locations for refiling the entry and lets you select one with
      completion.  The item (or all items in the region) is filed below
      the target heading as a subitem.  Depending on
      ‘org-reverse-note-order’, it is either the first or last subitem.
 
      By default, all level 1 headlines in the current buffer are
      considered to be targets, but you can have more complex definitions
      across a number of files.  See the variable ‘org-refile-targets’
      for details.  If you would like to select a location via a
      file-path-like completion along the outline path, see the variables
      ‘org-refile-use-outline-path’ and
      ‘org-outline-path-complete-in-steps’.  If you would like to be able
      to create new nodes as new parents for refiling on the fly, check
      the variable ‘org-refile-allow-creating-parent-nodes’.  When the
      variable ‘org-log-refile’(1) is set, a timestamp or a note is
      recorded whenever an entry is refiled.
 
 ‘C-u C-c C-w’
      Use the refile interface to jump to a heading.
 
 ‘C-u C-u C-c C-w’ (‘org-refile-goto-last-stored’)
      Jump to the location where ‘org-refile’ last moved a tree to.
 
 ‘C-2 C-c C-w’
      Refile as the child of the item currently being clocked.
 
 ‘C-3 C-c C-w’
      Refile and keep the entry in place.  Also see ‘org-refile-keep’ to
      make this the default behavior, and beware that this may result in
      duplicated ‘ID’ properties.
 
 ‘C-0 C-c C-w’ or ‘C-u C-u C-u C-c C-w’ (‘org-refile-cache-clear’)
      Clear the target cache.  Caching of refile targets can be turned on
      by setting ‘org-refile-use-cache’.  To make the command see new
      possible targets, you have to clear the cache with this command.
 
 ‘C-c M-w’ (‘org-refile-copy’)
      Copying works like refiling, except that the original note is not
      deleted.
 
 ‘C-c C-M-w’ (‘org-refile-reverse’)
      Works like refiling, except that it temporarily toggles how the
      value of ‘org-reverse-note-order’ applies to the current buffer.
      So if ‘org-refile’ would append the entry as the last entry under
      the target header, ‘org-refile-reverse’ will prepend it as the
      first entry, and vice-versa.
 
    ---------- Footnotes ----------
 
    (1) Note the corresponding ‘STARTUP’ options ‘logrefile’,
 ‘lognoterefile’, and ‘nologrefile’.

 9.2 Archiving
 =============
 
 When a project represented by a (sub)tree is finished, you may want to
 move the tree out of the way and to stop it from contributing to the
 agenda.  Archiving is important to keep your working files compact and
 global searches like the construction of agenda views fast.
 
 ‘C-c C-x C-a’ (‘org-archive-subtree-default’)
      Archive the current entry using the command specified in the
      variable ‘org-archive-default-command’.
 
 * Menu:
 
 * Moving subtrees::              Moving a tree to an archive file.
 * Internal archiving::           Switch off a tree but keep it in the file.
 
 
 File: org.info,  Node: Moving subtrees,  Next: Internal archiving,  Up: Archiving
 
 9.2.1 Moving a tree to an archive file
 --------------------------------------
 
 The most common archiving action is to move a project tree to another
 file, the archive file.
 
 ‘C-c C-x C-s’ or short ‘C-c $’ (‘org-archive-subtree’)
      Archive the subtree starting at point position to the location
      given by ‘org-archive-location’.
 
 ‘C-u C-c C-x C-s’
      Check if any direct children of the current headline could be moved
      to the archive.  To do this, check each subtree for open TODO
      entries.  If none is found, the command offers to move it to the
      archive location.  If point is _not_ on a headline when this
      command is invoked, check level 1 trees.
 
 ‘C-u C-u C-c C-x C-s’
      As above, but check subtree for timestamps instead of TODO entries.
      The command offers to archive the subtree if it _does_ contain a
      timestamp, and that timestamp is in the past.
 
    The default archive location is a file in the same directory as the
 current file, with the name derived by appending ‘_archive’ to the
 current file name.  You can also choose what heading to file archived
 items under, with the possibility to add them to a datetree in a file.
 For information and examples on how to specify the file and the heading,
 see the documentation string of the variable ‘org-archive-location’.
 
    There is also an in-buffer option for setting this variable, for
 example:
 
      #+ARCHIVE: %s_done::
 
    If you would like to have a special archive location for a single
 entry or a (sub)tree, give the entry an ‘ARCHIVE’ property with the
 location as the value (see *note Properties and Columns::).
 
    When a subtree is moved, it receives a number of special properties
 that record context information like the file from where the entry came,
 its outline path the archiving time etc.  Configure the variable
 ‘org-archive-save-context-info’ to adjust the amount of information
 added.
 
    When ‘org-archive-subtree-save-file-p’ is non-‘nil’, save the target
 archive buffer.
 
 
 File: org.info,  Node: Internal archiving,  Prev: Moving subtrees,  Up: Archiving
 
 9.2.2 Internal archiving
 ------------------------
 
 If you want to just switch off—for agenda views—certain subtrees without
 moving them to a different file, you can use the ‘ARCHIVE’ tag.
 
    A headline that is marked with the ‘ARCHIVE’ tag (see *note Tags::)
 stays at its location in the outline tree, but behaves in the following
 way:
 
    • It does not open when you attempt to do so with a visibility
      cycling command (see *note Visibility Cycling::).  You can force
      cycling archived subtrees with ‘C-c C-<TAB>’, or by setting the
      option ‘org-cycle-open-archived-trees’.  Also normal outline
      commands, like ‘org-show-all’, open archived subtrees.
 
    • During sparse tree construction (see *note Sparse Trees::), matches
      in archived subtrees are not exposed, unless you configure the
      option ‘org-sparse-tree-open-archived-trees’.
 
    • During agenda view construction (see *note Agenda Views::), the
      content of archived trees is ignored unless you configure the
      option ‘org-agenda-skip-archived-trees’, in which case these trees
      are always included.  In the agenda you can press ‘v a’ to get
      archives temporarily included.
 
    • Archived trees are not exported (see *note Exporting::), only the
      headline is.  Configure the details using the variable
      ‘org-export-with-archived-trees’.
 
    • Archived trees are excluded from column view unless the variable
      ‘org-columns-skip-archived-trees’ is configured to ‘nil’.
 
    The following commands help manage the ‘ARCHIVE’ tag:
 
 ‘C-c C-x a’ (‘org-toggle-archive-tag’)
      Toggle the archive tag for the current headline.  When the tag is
      set, the headline changes to a shadowed face, and the subtree below
      it is hidden.
 
 ‘C-u C-c C-x a’
      Check if any direct children of the current headline should be
      archived.  To do this, check each subtree for open TODO entries.
      If none is found, the command offers to set the ‘ARCHIVE’ tag for
      the child.  If point is _not_ on a headline when this command is
      invoked, check the level 1 trees.
 
 ‘C-c C-<TAB>’ (‘org-cycle-force-archived’)
      Cycle a tree even if it is tagged with ‘ARCHIVE’.
 
 ‘C-c C-x A’ (‘org-archive-to-archive-sibling’)
      Move the current entry to the _Archive Sibling_.  This is a sibling
      of the entry with the heading ‘Archive’ and the archive tag.  The
      entry becomes a child of that sibling and in this way retains a lot
      of its original context, including inherited tags and approximate
      position in the outline.

 10 Capture and Attachments
 **************************
 
 An important part of any organization system is the ability to quickly
 capture new ideas and tasks, and to associate reference material with
 them.  Org does this using a process called _capture_.  It also can
 store files related to a task (_attachments_) in a special directory.
 Finally, it can parse RSS feeds for information.  To learn how to let
 external programs (for example a web browser) trigger Org to capture
 material, see *note Protocols::.
 
 * Menu:
 
 * Capture::                      Capturing new stuff.
 * Attachments::                  Attach files to outlines.

 10.1 Capture
 ============
 
 Capture lets you quickly store notes with little interruption of your
 work flow.  Org’s method for capturing new items is heavily inspired by
 John Wiegley’s excellent Remember package.
 
 * Menu:
 
 * Setting up capture::           Where notes will be stored.
 * Using capture::                Commands to invoke and terminate capture.

 File: org.info,  Node: Setting up capture,  Next: Using capture,  Up: Capture
 
 10.1.1 Setting up capture
 -------------------------
 
 The following customization sets a default target file for notes.
 
      (setq org-default-notes-file (concat org-directory "/notes.org"))
 
    You may also define a global key for capturing new material (see
 *note Activation::).
 
 
 File: org.info,  Node: Using capture,  Next: Capture templates,  Prev: Setting up capture,  Up: Capture
 
 10.1.2 Using capture
 --------------------
 
 ‘M-x org-capture’ (‘org-capture’)
      Display the capture templates menu.  If you have templates defined
      (see *note Capture templates::), it offers these templates for
      selection or use a new Org outline node as the default template.
      It inserts the template into the target file and switch to an
      indirect buffer narrowed to this new node.  You may then insert the
      information you want.
 
 ‘C-c C-c’ (‘org-capture-finalize’)
      Once you have finished entering information into the capture
      buffer, ‘C-c C-c’ returns you to the window configuration before
      the capture process, so that you can resume your work without
      further distraction.  When called with a prefix argument, finalize
      and then jump to the captured item.
 
 ‘C-c C-w’ (‘org-capture-refile’)
      Finalize the capture process by refiling the note to a different
      place (see *note Refile and Copy::).  Please realize that this is a
      normal refiling command that will be executed—so point position at
      the moment you run this command is important.  If you have inserted
      a tree with a parent and children, first move point back to the
      parent.  Any prefix argument given to this command is passed on to
      the ‘org-refile’ command.
 
 ‘C-c C-k’ (‘org-capture-kill’)
      Abort the capture process and return to the previous state.
 
    You can also call ‘org-capture’ in a special way from the agenda,
 using the ‘k c’ key combination.  With this access, any timestamps
 inserted by the selected capture template defaults to the date at point
 in the agenda, rather than to the current date.
 
    To find the locations of the last stored capture, use ‘org-capture’
 with prefix commands:
 
 ‘C-u M-x org-capture’
      Visit the target location of a capture template.  You get to select
      the template in the usual way.
 
 ‘C-u C-u M-x org-capture’
      Visit the last stored capture item in its buffer.
 
    You can also jump to the bookmark ‘org-capture-last-stored’, which is
 automatically created unless you customize ‘org-bookmark-names-plist’.
 
    To insert the capture at point in an Org buffer, call ‘org-capture’
 with a ‘C-0’ prefix argument.
 
 
 File: org.info,  Node: Capture templates,  Prev: Using capture,  Up: Capture
 
 10.1.3 Capture templates
 ------------------------
 
 You can use templates for different types of capture items, and for
 different target locations.  The easiest way to create such templates is
 through the customize interface.
 
 ‘C’
      Customize the variable ‘org-capture-templates’.
 
    Before we give the formal description of template definitions, let’s
 look at an example.  Say you would like to use one template to create
 general TODO entries, and you want to put these entries under the
 heading ‘Tasks’ in your file ‘~/org/gtd.org’.  Also, a date tree in the
 file ‘journal.org’ should capture journal entries.  A possible
 configuration would look like:
 
      (setq org-capture-templates
            '(("t" "Todo" entry (file+headline "~/org/gtd.org" "Tasks")
               "* TODO %?\n  %i\n  %a")
              ("j" "Journal" entry (file+datetree "~/org/journal.org")
               "* %?\nEntered on %U\n  %i\n  %a")))
 
    If you then press ‘t’ from the capture menu, Org will prepare the
 template for you like this:
 
      * TODO
        [[file:LINK TO WHERE YOU INITIATED CAPTURE]]
 
 During expansion of the template, ‘%a’ has been replaced by a link to
 the location from where you called the capture command.  This can be
 extremely useful for deriving tasks from emails, for example.  You fill
 in the task definition, press ‘C-c C-c’ and Org returns you to the same
 place where you started the capture process.
 
    To define special keys to capture to a particular template without
 going through the interactive template selection, you can create your
 key binding like this:
 
      (define-key global-map (kbd "C-c x")
        (lambda () (interactive) (org-capture nil "x")))
 
 * Menu:
 
 * Template elements::            What is needed for a complete template entry.
 * Template expansion::           Filling in information about time and context.
 * Templates in contexts::        Only show a template in a specific context.
 
 
 File: org.info,  Node: Template elements,  Next: Template expansion,  Up: Capture templates
 
 10.1.3.1 Template elements
 ..........................
 
 Now lets look at the elements of a template definition.  Each entry in
 ‘org-capture-templates’ is a list with the following items:
 
 keys
      The keys that selects the template, as a string, characters only,
      for example ‘"a"’, for a template to be selected with a single key,
      or ‘"bt"’ for selection with two keys.  When using several keys,
      keys using the same prefix key must be sequential in the list and
      preceded by a 2-element entry explaining the prefix key, for
      example:
 
           ("b" "Templates for marking stuff to buy")
 
      If you do not define a template for the ‘C’ key, this key opens the
      Customize buffer for this complex variable.
 
 description
      A short string describing the template, shown during selection.
 
 type
      The type of entry, a symbol.  Valid values are:
 
      ‘entry’
           An Org mode node, with a headline.  Will be filed as the child
           of the target entry or as a top-level entry.  The target file
           should be an Org file.
 
      ‘item’
           A plain list item, placed in the first plain list at the
           target location.  Again the target file should be an Org file.
 
      ‘checkitem’
           A checkbox item.  This only differs from the plain list item
           by the default template.
 
      ‘table-line’
           A new line in the first table at the target location.  Where
           exactly the line will be inserted depends on the properties
           ‘:prepend’ and ‘:table-line-pos’ (see below).
 
      ‘plain’
           Text to be inserted as it is.
 
 target
      Specification of where the captured item should be placed.  In Org
      files, targets usually define a node.  Entries will become children
      of this node.  Other types will be added to the table or list in
      the body of this node.  Most target specifications contain a file
      name.  If that file name is the empty string, it defaults to
      ‘org-default-notes-file’.  A file can also be given as a variable
      or as a function called with no argument.  When an absolute path is
      not specified for a target, it is taken as relative to
      ‘org-directory’.
 
      Valid values are:
 
      ‘(file "path/to/file")’
           Text will be placed at the beginning or end of that file.
 
      ‘(id "id of existing org entry")’
           Filing as child of this entry, or in the body of the entry.
 
      ‘(file+headline "filename" "node headline")’
           Fast configuration if the target heading is unique in the
           file.
 
      ‘(file+olp "filename" "Level 1 heading" "Level 2" ...)’
           For non-unique headings, the full path is safer.
 
      ‘(file+regexp "filename" "regexp to find location")’
           Use a regular expression to position point.
 
      ‘(file+olp+datetree "filename" [ "Level 1 heading" ...])’
           This target(1) creates a heading in a date tree(2) for today’s
           date.  If the optional outline path is given, the tree will be
           built under the node it is pointing to, instead of at top
           level.  Check out the ‘:time-prompt’ and ‘:tree-type’
           properties below for additional options.
 
      ‘(file+function "filename" function-finding-location)’
           A function to find the right location in the file.
 
      ‘(clock)’
           File to the entry that is currently being clocked.
 
      ‘(here)’
           The position of ‘point’.
 
      ‘(function function-finding-location)’
           Most general way: write your own function which both visits
           the file and moves point to the right location.
 
 template
      The template for creating the capture item.  If you leave this
      empty, an appropriate default template will be used.  Otherwise
      this is a string with escape codes, which will be replaced
      depending on time and context of the capture call.  You may also
      get this template string from a file(3), or dynamically, from a
      function using either syntax:
 
           (file "/path/to/template-file")
           (function FUNCTION-RETURNING-THE-TEMPLATE)
 
 properties
      The rest of the entry is a property list of additional options.
      Recognized properties are:
 
      ‘:prepend’
           Normally new captured information will be appended at the
           target location (last child, last table line, last list item,
           ...).  Setting this property changes that.
 
      ‘:immediate-finish’
           When set, do not offer to edit the information, just file it
           away immediately.  This makes sense if the template only needs
           information that can be added automatically.
 
      ‘:jump-to-captured’
           When set, jump to the captured entry when finished.
 
      ‘:empty-lines’
           Set this to the number of lines to insert before and after the
           new item.  Default 0, and the only other common value is 1.
 
      ‘:empty-lines-after’
           Set this to the number of lines that should be inserted after
           the new item.  Overrides ‘:empty-lines’ for the number of
           lines inserted after.
 
      ‘:empty-lines-before’
           Set this to the number of lines that should be inserted before
           the new item.  Overrides ‘:empty-lines’ for the number lines
           inserted before.
 
      ‘:clock-in’
           Start the clock in this item.
 
      ‘:clock-keep’
           Keep the clock running when filing the captured entry.
 
      ‘:clock-resume’
           If starting the capture interrupted a clock, restart that
           clock when finished with the capture.  Note that ‘:clock-keep’
           has precedence over ‘:clock-resume’.  When setting both to
           non-‘nil’, the current clock will run and the previous one
           will not be resumed.
 
      ‘:time-prompt’
           Prompt for a date/time to be used for date/week trees and when
           filling the template.  Without this property, capture uses the
           current date and time.  Even if this property has not been
           set, you can force the same behavior by calling ‘org-capture’
           with a ‘C-1’ prefix argument.
 
      ‘:tree-type’
           Use ‘week’ to make a week tree instead of the month-day tree,
           i.e., place the headings for each day under a heading with the
           current ISO week.  Use ‘month’ to group entries by month only.
           Default is to group entries by day.
 
      ‘:unnarrowed’
           Do not narrow the target buffer, simply show the full buffer.
           Default is to narrow it so that you only see the new material.
 
      ‘:table-line-pos’
           Specification of the location in the table where the new line
           should be inserted.  It should be a string like ‘II-3’ meaning
           that the new line should become the third line before the
           second horizontal separator line.
 
      ‘:kill-buffer’
           If the target file was not yet visited when capture was
           invoked, kill the buffer again after capture is completed.
 
      ‘:no-save’
           Do not save the target file after finishing the capture.
 
      ‘:refile-targets’
           Temporarily set ‘org-refile-targets’ to the value of this
           property.
 
      ‘:hook’
           A nullary function or list of nullary functions run before
           ‘org-capture-mode-hook’ when the template is selected.
 
      ‘:prepare-finalize’
           A nullary function or list of nullary functions run before
           ‘org-capture-prepare-finalize-hook’ when the template is
           selected.
 
      ‘:before-finalize’
           A nullary function or list of nullary functions run before
           ‘org-capture-before-finalize-hook’ when the template is
           selected.
 
      ‘:after-finalize’
           A nullary function or list of nullary functions run before
           ‘org-capture-after-finalize-hook’ when the template is
           selected.
 
    ---------- Footnotes ----------
 
    (1) Org used to offer four different targets for date/week tree
 capture.  Now, Org automatically translates these to use
 ‘file+olp+datetree’, applying the ‘:time-prompt’ and ‘:tree-type’
 properties.  Please rewrite your date/week-tree targets using
 ‘file+olp+datetree’ since the older targets are now deprecated.
 
    (2) A date tree is an outline structure with years on the highest
 level, months or ISO weeks as sublevels and then dates on the lowest
 level.
      * 2022
      ** 2022-10 October
      *** 2022-10-07 Friday

    TODO state, priority, tags, statistics cookies, and COMMENT keywords
 are allowed in the tree structure.
 
    (3) When the file name is not absolute, Org assumes it is relative to
 ‘org-directory’.

 10.1.3.2 Template expansion
 ...........................
 
 In the template itself, special “%-escapes”(1) allow dynamic insertion
 of content.  The templates are expanded in the order given here:
 
 ‘%[FILE]’
      Insert the contents of the file given by FILE.
 
 ‘%(EXP)’
      Evaluate Elisp expression EXP and replace it with the result.  The
      EXP form must return a string.  Only placeholders pre-existing
      within the template, or introduced with ‘%[file]’, are expanded
      this way.  Since this happens after expanding non-interactive
      “%-escapes”, those can be used to fill the expression.
 
 ‘%<FORMAT>’
      The result of format-time-string on the FORMAT specification.
 
 ‘%t’
      Timestamp, date only.
 
 ‘%T’
      Timestamp, with date and time.
 
 ‘%u’, ‘%U’
      Like ‘%t’, ‘%T’ above, but inactive timestamps.
 
 ‘%i’
      Initial content, the region when capture is called while the region
      is active.  If there is text before ‘%i’ on the same line, such as
      indentation, and ‘%i’ is not inside a ‘%(exp)’ form, that prefix is
      added before every line in the inserted text.
 
 ‘%a’
      Annotation, normally the link created with ‘org-store-link’.
 
 ‘%A’
      Like ‘%a’, but prompt for the description part.
 
 ‘%l’
      Like ‘%a’, but only insert the literal link.
 
 ‘%L’
      Like ‘%l’, but without brackets (the link content itself).
 
 ‘%c’
      Current kill ring head.
 
 ‘%x’
      Content of the X clipboard.
 
 ‘%k’
      Title of the currently clocked task.
 
 ‘%K’
      Link to the currently clocked task.
 
 ‘%n’
      User name (taken from ‘user-full-name’).
 
 ‘%f’
      File visited by current buffer when org-capture was called.
 
 ‘%F’
      Full path of the file or directory visited by current buffer.
 
 ‘%:keyword’
      Specific information for certain link types, see below.
 
 ‘%^g’
      Prompt for tags, with completion on tags in target file.
 
 ‘%^G’
      Prompt for tags, with completion all tags in all agenda files.
 
 ‘%^t’
      Like ‘%t’, but prompt for date.  Similarly ‘%^T’, ‘%^u’, ‘%^U’.
      You may define a prompt like ‘%^{Birthday}t’.
 
 ‘%^C’
      Interactive selection of which kill or clip to use.
 
 ‘%^L’
      Like ‘%^C’, but insert as link.
 
 ‘%^{PROP}p’
      Prompt the user for a value for property PROP.  You may specify a
      default value with ‘%^{PROP|default}’.
 
 ‘%^{PROMPT}X’, X is one of g,G,t,T,u,U,C,L
      Prompt the user as in ‘%^X’, but use the custom prompt string.  You
      may specify a default value and completions with
      ‘%^{PROMPT|default|completion1|completion2|completion3...}X’.
 
 ‘%^{PROMPT}’
      Prompt the user for a string and replace this sequence with it.
      You may specify a default value and a completion table with
      ‘%^{prompt|default|completion2|completion3...}’.  The arrow keys
      access a prompt-specific history.
 
 ‘%\N’
      Insert the text entered at the Nth ‘%^{PROMPT}’, where N is a
      number, starting from 1.
 
 ‘%?’
      After completing the template, position point here.
 
    For specific link types, the following keywords are defined(2):
 
 Link type      Available keywords
 --------------------------------------------------------------------------
 bbdb           ‘%:name’, ‘%:company’
 irc            ‘%:server’, ‘%:port’, ‘%:nick’
 mh, rmail      ‘%:type’, ‘%:subject’, ‘%:message-id’
                ‘%:from’, ‘%:fromname’, ‘%:fromaddress’
                ‘%:to’, ‘%:toname’, ‘%:toaddress’
                ‘%:date’ (message date header field)
                ‘%:date-timestamp’ (date as active timestamp)
                ‘%:date-timestamp-inactive’ (date as inactive timestamp)
                ‘%:fromto’ (either “to NAME” or “from NAME”)(3)
 gnus           ‘%:group’, for messages also all email fields
 w3, w3m        ‘%:url’
 info           ‘%:file’, ‘%:node’
 calendar       ‘%:date’
 org-protocol   ‘%:link’, ‘%:description’, ‘%:annotation’

    (1) If you need one of these sequences literally, escape the ‘%’ with
 a backslash.
 
    (2) If you define your own link types (see *note Adding Hyperlink
 Types::), any property you store with ‘org-store-link-props’ can be
 accessed in capture templates in a similar way.

 10.1.3.3 Templates in contexts
 ..............................
 
 To control whether a capture template should be accessible from a
 specific context, you can customize ‘org-capture-templates-contexts’.
 Let’s say, for example, that you have a capture template “p” for storing
 Gnus emails containing patches.  Then you would configure this option
 like this:
 
      (setq org-capture-templates-contexts
            '(("p" ((in-mode . "message-mode")))))
 
    You can also tell that the command key ‘p’ should refer to another
 template.  In that case, add this command key like this:
 
      (setq org-capture-templates-contexts
            '(("p" "q" ((in-mode . "message-mode")))))
 
    See the docstring of the variable for more information.

 10.2 Attachments
 ================
 
 It is often useful to associate reference material with an outline node.
 Small chunks of plain text can simply be stored in the subtree of a
 project.  Hyperlinks (see *note Hyperlinks::) can establish associations
 with files that live elsewhere on a local, or even remote, computer,
 like emails or source code files belonging to a project.
 
    Another method is _attachments_, which are files located in a
 directory belonging to an outline node.  Org uses directories either
 named by a unique ID of each entry, or by a ‘DIR’ property.

 * Attach from Dired::            Using dired to select an attachment
 
 
 File: org.info,  Node: Attachment defaults and dispatcher,  Next: Attachment options,  Up: Attachments
 
 10.2.1 Attachment defaults and dispatcher
 -----------------------------------------
 
 By default, Org attach uses ID properties when adding attachments to
 outline nodes.  This makes working with attachments fully automated.
 There is no decision needed for folder-name or location.  ID-based
 directories are by default located in the ‘data/’ directory, which lives
 in the same directory where your Org file lives(1).
 
    When attachments are made using ‘org-attach’ a default tag ‘ATTACH’
 is added to the node that gets the attachments.
 
    For more control over the setup, see *note Attachment options::.
 
    The following commands deal with attachments:
 
 ‘C-c C-a’ (‘org-attach’)
      The dispatcher for commands related to the attachment system.
      After these keys, a list of commands is displayed and you must
      press an additional key to select a command:
 
      ‘a’ (‘org-attach-attach’)
           Select a file and move it into the task’s attachment
           directory.  The file is copied, moved, or linked, depending on
           ‘org-attach-method’.  Note that hard links are not supported
           on all systems.
 
      ‘c’/‘m’/‘l’
           Attach a file using the copy/move/link method.  Note that hard
           links are not supported on all systems.
 
      ‘b’ (‘org-attach-buffer’)
           Select a buffer and save it as a file in the task’s attachment
           directory.
 
      ‘n’ (‘org-attach-new’)
           Create a new attachment as an Emacs buffer.
 
      ‘z’ (‘org-attach-sync’)
           Synchronize the current task with its attachment directory, in
           case you added attachments yourself.
 
      ‘o’ (‘org-attach-open’)
           Open current task’s attachment.  If there is more than one,
           prompt for a file name first.  Opening follows the rules set
           by ‘org-file-apps’.  For more details, see the information on
           following hyperlinks (see *note Handling Links::).
 
      ‘O’ (‘org-attach-open-in-emacs’)
           Also open the attachment, but force opening the file in Emacs.
 
      ‘f’ (‘org-attach-reveal’)
           Open the current task’s attachment directory.
 
      ‘F’ (‘org-attach-reveal-in-emacs’)
           Also open the directory, but force using Dired in Emacs.
 
      ‘d’ (‘org-attach-delete-one’)
           Select and delete a single attachment.
 
      ‘D’ (‘org-attach-delete-all’)
           Delete all of a task’s attachments.  A safer way is to open
           the directory in Dired and delete from there.
 
      ‘s’ (‘org-attach-set-directory’)
           Set a specific directory as the entry’s attachment directory.
           This works by putting the directory path into the ‘DIR’
           property.
 
      ‘S’ (‘org-attach-unset-directory’)
           Remove the attachment directory.  This command removes the
           ‘DIR’ property and asks the user to either move content inside
           that folder, if an ‘ID’ property is set, delete the content,
           or to leave the attachment directory as is but no longer
           attached to the outline node.
 
    ---------- Footnotes ----------
 
    (1) If you move entries or Org files from one directory to another,
 you may want to configure ‘org-attach-id-dir’ to contain an absolute
 path.
 
 
 File: org.info,  Node: Attachment options,  Next: Attachment links,  Prev: Attachment defaults and dispatcher,  Up: Attachments
 
 10.2.2 Attachment options
 -------------------------
 
 There are a couple of options for attachments that are worth mentioning.
 
 ‘org-attach-id-dir’
      The directory where attachments are stored when ‘ID’ is used as
      method.
 
 ‘org-attach-dir-relative’
      When setting the ‘DIR’ property on a node using ‘C-c C-a s’
      (‘org-attach-set-directory’), absolute links are entered by
      default.  This option changes that to relative links.
 
 ‘org-attach-use-inheritance’
      By default folders attached to an outline node are inherited from
      parents according to ‘org-use-property-inheritance’.  If one
      instead want to set inheritance specifically for Org attach that
      can be done using ‘org-attach-use-inheritance’.  Inheriting
      documents through the node hierarchy makes a lot of sense in most
      cases.  Especially when using attachment links (see *note
      Attachment links::).  The following example shows one use case for
      attachment inheritance:
 
           * Chapter A ...
             :PROPERTIES:
             :DIR: Chapter A/
             :END:
           ** Introduction
           Some text
 
           #+NAME: Image 1
           [[attachment:image 1.jpg]]
 
      Without inheritance one would not be able to resolve the link to
      ‘image 1.jpg’, since the link is inside a sub-heading to ‘Chapter
      A’.
 
      Inheritance works the same way for both ‘ID’ and ‘DIR’ property.
      If both properties are defined on the same headline then ‘DIR’
      takes precedence.  This is also true if inheritance is enabled.  If
      ‘DIR’ is inherited from a parent node in the outline, that property
      still takes precedence over an ‘ID’ property defined on the node
      itself.
 
 ‘org-attach-method’
      When attaching files using the dispatcher ‘C-c C-a’ it defaults to
      copying files.  The behavior can be changed by customizing
      ‘org-attach-method’.  Options are Copy, Move/Rename, Hard link or
      Symbolic link.
 
 ‘org-attach-preferred-new-method’
      This customization lets you choose the default way to attach to
      nodes without existing ‘ID’ and ‘DIR’ property.  It defaults to
      ‘id’ but can also be set to ‘dir’, ‘ask’ or ‘nil’.
 
 ‘org-attach-archive-delete’
      Configure this to determine if attachments should be deleted or not
      when a subtree that has attachments is archived.
 
 ‘org-attach-auto-tag’
      When attaching files to a heading it will be assigned a tag
      according to what is set here.
 
 ‘org-attach-id-to-path-function-list’
      When ‘ID’ is used for attachments, the ID is parsed into a part of
      a directory-path.  See ‘org-attach-id-uuid-folder-format’ for the
      default function.  Define a new one and add it as first element in
      ‘org-attach-id-to-path-function-list’ if you want the folder
      structure in any other way.  All functions in this list will be
      tried when resolving existing ID’s into paths, to maintain backward
      compatibility with existing folders in your system.
 
 ‘org-attach-store-link-p’
      Stores a link to the file that is being attached.  The link is
      stored in ‘org-stored-links’ for later insertion with ‘C-c C-l’
      (see *note Handling Links::).  Depending on what option is set in
      ‘org-attach-store-link-p’, the link is stored to either the
      original location as a file link, the attachment location as an
      attachment link or to the attachment location as a file link.
 
 ‘org-attach-commands’
      List of all commands used in the attach dispatcher.
 
 ‘org-attach-expert’
      Do not show the splash buffer with the attach dispatcher when
      ‘org-attach-expert’ is set to non-‘nil’.
 
    See customization group ‘Org Attach’ if you want to change the
 default settings.

 10.2.3 Attachment links
 -----------------------
 
 Attached files and folders can be referenced using attachment links.
 This makes it easy to refer to the material added to an outline node.
 Especially if it was attached using the unique ID of the entry!
 
      * TODO Some task
        :PROPERTIES:
        :ID:       95d50008-c12e-479f-a4f2-cc0238205319
        :END:
      See attached document for more information: [[attachment:info.org]]
 
    See *note External Links:: for more information about these links.
 
 
 File: org.info,  Node: Automatic version-control with Git,  Next: Attach from Dired,  Prev: Attachment links,  Up: Attachments
 
 10.2.4 Automatic version-control with Git
 -----------------------------------------
 
 If the directory attached to an outline node is a Git repository, Org
 can be configured to automatically commit changes to that repository
 when it sees them.
 
    To make Org mode take care of versioning of attachments for you, add
 the following to your Emacs config:
 
      (require 'org-attach-git)
 
 
 File: org.info,  Node: Attach from Dired,  Prev: Automatic version-control with Git,  Up: Attachments
 
 10.2.5 Attach from Dired
 ------------------------
 
 It is possible to attach files to a subtree from a Dired buffer.  To use
 this feature, have one window in Dired mode containing the file(s) to be
 attached and another window with point in the subtree that shall get the
 attachments.  In the Dired window, with point on a file, ‘M-x
 org-attach-dired-to-subtree’ attaches the file to the subtree using the
 attachment method set by variable ‘org-attach-method’.  When files are
 marked in the Dired window then all marked files get attached.
 
    Add the following lines to the Emacs init file to have ‘C-c C-x a’
 attach files in Dired buffers.
 
      (add-hook 'dired-mode-hook
                (lambda ()
                  (define-key dired-mode-map
                    (kbd "C-c C-x a")
                    #'org-attach-dired-to-subtree)))
 
    The following code shows how to bind the previous command with a
 specific attachment method.
 
      (add-hook 'dired-mode-hook
                (lambda ()
                  (define-key dired-mode-map (kbd "C-c C-x c")
                    (lambda ()
                      (interactive)
                      (let ((org-attach-method 'cp))
                        (call-interactively #'org-attach-dired-to-subtree))))))
 
 
 File: org.info,  Node: RSS Feeds,  Prev: Attachments,  Up: Capture and Attachments
 
 10.3 RSS Feeds
 ==============
 
 Org can add and change entries based on information found in RSS feeds
 and Atom feeds.  You could use this to make a task out of each new
 podcast in a podcast feed.  Or you could use a phone-based note-creating
 service on the web to import tasks into Org.  To access feeds, configure
 the variable ‘org-feed-alist’.  The docstring of this variable has
 detailed information.  With the following
 
      (setq org-feed-alist
            '(("Slashdot"
               "https://rss.slashdot.org/Slashdot/slashdot"
               "~/txt/org/feeds.org" "Slashdot Entries")))
 
 new items from the feed provided by ‘rss.slashdot.org’ result in new
 entries in the file ‘~/org/feeds.org’ under the heading ‘Slashdot
 Entries’, whenever the following command is used:
 
 ‘C-c C-x g’ (‘org-feed-update-all’)
      Collect items from the feeds configured in ‘org-feed-alist’ and act
      upon them.
 
 ‘C-c C-x G’ (‘org-feed-goto-inbox’)
      Prompt for a feed name and go to the inbox configured for this
      feed.
 
    Under the same headline, Org creates a drawer ‘FEEDSTATUS’ in which
 it stores information about the status of items in the feed, to avoid
 adding the same item several times.
 
    For more information, including how to read atom feeds, see
 ‘org-feed.el’ and the docstring of ‘org-feed-alist’.

 To get an overview of open action items, or of events that are important
 for a particular date, this information must be collected, sorted and
 displayed in an organized way.
 
    Org can select items based on various criteria and display them in a
 separate buffer.  Six different view types are provided:
 
    • an _agenda_ that is like a calendar and shows information for
      specific dates,
 
    • a _TODO list_ that covers all unfinished action items,
 
    • a _match view_, showings headlines based on the tags, properties,
      and TODO state associated with them,
 
    • a _text search view_ that shows all entries from multiple files
      that contain specified keywords,
 
    • a _stuck projects view_ showing projects that currently do not move
      along, and
 
    • _custom views_ that are special searches and combinations of
      different views.
 
    The extracted information is displayed in a special _agenda buffer_.
 This buffer is read-only, but provides commands to visit the
 corresponding locations in the original Org files, and even to edit
 these files remotely.
 
    By default, the report ignores commented (see *note Comment Lines::)
 and archived (see *note Internal archiving::) entries.  You can override
 this by setting ‘org-agenda-skip-comment-trees’ and
 ‘org-agenda-skip-archived-trees’ to ‘nil’.
 
    Two variables control how the agenda buffer is displayed and whether
 the window configuration is restored when the agenda exits:
 ‘org-agenda-window-setup’ and ‘org-agenda-restore-windows-after-quit’.

 11.1 Agenda Files
 =================
 
 The information to be shown is normally collected from all _agenda
 files_, the files listed in the variable ‘org-agenda-files’(1).  If a
 directory is part of this list, all files with the extension ‘.org’ in
 this directory are part of the list.
 
    Thus, even if you only work with a single Org file, that file should
 be put into the list(2).  You can customize ‘org-agenda-files’, but the
 easiest way to maintain it is through the following commands
 
 ‘C-c [’ (‘org-agenda-file-to-front’)
      Add current file to the list of agenda files.  The file is added to
      the front of the list.  If it was already in the list, it is moved
      to the front.  With a prefix argument, file is added/moved to the
      end.
 
 ‘C-c ]’ (‘org-remove-file’)
      Remove current file from the list of agenda files.
 
 ‘C-'’
 ‘C-,’ (‘org-cycle-agenda-files’)
      Cycle through agenda file list, visiting one file after the other.
 
 ‘M-x org-switchb’
      Command to use an Iswitchb-like interface to switch to and between
      Org buffers.
 
 The Org menu contains the current list of files and can be used to visit
 any of them.
 
    If you would like to focus the agenda temporarily on a file not in
 this list, or on just one file in the list, or even on only a subtree in
 a file, then this can be done in different ways.  For a single agenda
 command, you may press ‘<’ once or several times in the dispatcher (see
 *note Agenda Dispatcher::).  To restrict the agenda scope for an
 extended period, use the following commands:
 
 ‘C-c C-x <’ (‘org-agenda-set-restriction-lock’)
      Restrict the agenda to the current subtree.  If there already is a
      restriction at point, remove it.  When called with a universal
      prefix argument or with point before the first headline in a file,
      set the agenda scope to the entire file.  This restriction remains
      in effect until removed with ‘C-c C-x >’, or by typing either ‘<’
      or ‘>’ in the agenda dispatcher.  If there is a window displaying
      an agenda view, the new restriction takes effect immediately.
 
 ‘C-c C-x >’ (‘org-agenda-remove-restriction-lock’)
      Remove the restriction created by ‘C-c C-x <’.
 
    When working with Speedbar, you can use the following commands in the
 Speedbar frame:
 
 ‘<’ (‘org-speedbar-set-agenda-restriction’)
      Restrict the agenda to the item—either an Org file or a subtree in
      such a file—at point in the Speedbar frame.  If agenda is already
      restricted there, remove the restriction.  If there is a window
      displaying an agenda view, the new restriction takes effect
      immediately.
 
 ‘>’ (‘org-agenda-remove-restriction-lock’)
      Remove the restriction.
 
    ---------- Footnotes ----------
 
    (1) If the value of that variable is not a list, but a single file
 name, then the list of agenda files in maintained in that external file.
 
    (2) When using the dispatcher, pressing ‘<’ before selecting a
 command actually limits the command to the current file, and ignores
 ‘org-agenda-files’ until the next dispatcher command.

 11.2 The Agenda Dispatcher
 ==========================
 
 The views are created through a dispatcher, accessible with ‘M-x
 org-agenda’, or, better, bound to a global key (see *note Activation::).
 It displays a menu from which an additional letter is required to
 execute a command.  The dispatcher offers the following default
 commands:
 
 ‘a’
      Create the calendar-like agenda (see *note Weekly/daily agenda::).
 
 ‘t’
 ‘T’
      Create a list of all TODO items (see *note Global TODO list::).
 
 ‘m’
 ‘M’
      Create a list of headlines matching a given expression (see *note
      Matching tags and properties::).
 
 ‘s’
      Create a list of entries selected by a boolean expression of
      keywords and/or regular expressions that must or must not occur in
      the entry.
 
 ‘/’
      Search for a regular expression in all agenda files and
      additionally in the files listed in
      ‘org-agenda-text-search-extra-files’.  This uses the Emacs command
      ‘multi-occur’.  A prefix argument can be used to specify the number
      of context lines for each match, the default is 1.
 
 ‘#’
      Create a list of stuck projects (see *note Stuck projects::).
 
 ‘!’
      Configure the list of stuck projects (see *note Stuck projects::).
 
 ‘<’
      Restrict an agenda command to the current buffer(1).  If narrowing
      is in effect restrict to the narrowed part of the buffer.  After
      pressing ‘<’, you still need to press the character selecting the
      command.
 
 ‘< <’
      If there is an active region, restrict the following agenda command
      to the region.  Otherwise, restrict it to the current subtree.
      After pressing ‘< <’, you still need to press the character
      selecting the command.
 
 ‘*’
      Toggle sticky agenda views.  By default, Org maintains only a
      single agenda buffer and rebuilds it each time you change the view,
      to make sure everything is always up to date.  If you switch
      between views often and the build time bothers you, you can turn on
      sticky agenda buffers (make this the default by customizing the
      variable ‘org-agenda-sticky’).  With sticky agendas, the dispatcher
      only switches to the selected view, you need to update it by hand
      with ‘r’ or ‘g’.  You can toggle sticky agenda view any time with
      ‘org-toggle-sticky-agenda’.
 
    You can also define custom commands that are accessible through the
 dispatcher, just like the default commands.  This includes the
 possibility to create extended agenda buffers that contain several
 blocks together, for example the weekly agenda, the global TODO list and
 a number of special tags matches.  See *note Custom Agenda Views::.
 
    ---------- Footnotes ----------
 
    (1) For backward compatibility, you can also press ‘1’ to restrict to
 the current buffer.

 11.3 The Built-in Agenda Views
 ==============================
 
 In this section we describe the built-in views.
 
 * Menu:
 
 * Weekly/daily agenda::          The calendar page with current tasks.
 * Global TODO list::             All unfinished action items.
 * Matching tags and properties:: Structured information with fine-tuned search.
 * Search view::                  Find entries by searching for text.
 * Stuck projects::               Find projects you need to review.
 
 
 File: org.info,  Node: Weekly/daily agenda,  Next: Global TODO list,  Up: Built-in Agenda Views
 
 11.3.1 Weekly/daily agenda
 --------------------------
 
 The purpose of the weekly/daily _agenda_ is to act like a page of a
 paper agenda, showing all the tasks for the current week or day.
 
 ‘M-x org-agenda a’ (‘org-agenda-list’)
      Compile an agenda for the current week from a list of Org files.
      The agenda shows the entries for each day.  With a numeric prefix
      argument(1)—like ‘C-u 2 1 M-x org-agenda a’—you may set the number
      of days to be displayed.
 
    The default number of days displayed in the agenda is set by the
 variable ‘org-agenda-span’.  This variable can be set to any number of
 days you want to see by default in the agenda, or to a span name, such a
 ‘day’, ‘week’, ‘month’ or ‘year’.  For weekly agendas, the default is to
 start on the previous Monday (see ‘org-agenda-start-on-weekday’).  You
 can also set the start date using a date shift: ‘(setq
 org-agenda-start-day "+10d")’ starts the agenda ten days from today in
 the future.  ‘org-agenda-start-on-weekday’ takes precedence over
 ‘org-agenda-start-day’ in weekly and bi-weekly agendas.
 
    Remote editing from the agenda buffer means, for example, that you
 can change the dates of deadlines and appointments from the agenda
 buffer.  The commands available in the Agenda buffer are listed in *note
 Agenda Commands::.
 
 Calendar/Diary integration
 ..........................
 
 Emacs contains the calendar and diary by Edward M. Reingold.  The
 calendar displays a three-month calendar with holidays from different
 countries and cultures.  The diary allows you to keep track of
 anniversaries, lunar phases, sunrise/set, recurrent appointments
 (weekly, monthly) and more.  In this way, it is quite complementary to
 Org.  It can be very useful to combine output from Org with the diary.
 
    In order to include entries from the Emacs diary into Org mode’s
 agenda, you only need to customize the variable
 
      (setq org-agenda-include-diary t)
 
 After that, everything happens automatically.  All diary entries
 including holidays, anniversaries, etc., are included in the agenda
 buffer created by Org mode.  ‘<SPC>’, ‘<TAB>’, and ‘<RET>’ can be used
 from the agenda buffer to jump to the diary file in order to edit
 existing diary entries.  The ‘i’ command to insert new entries for the
 current date works in the agenda buffer, as well as the commands ‘S’,
 ‘M’, and ‘C’ to display Sunrise/Sunset times, show lunar phases and to
 convert to other calendars, respectively.  ‘c’ can be used to switch
 back and forth between calendar and agenda.
 
    If you are using the diary only for expression entries and holidays,
 it is faster to not use the above setting, but instead to copy or even
 move the entries into an Org file.  Org mode evaluates diary-style
 expression entries, and does it faster because there is no overhead for
 first creating the diary display.  Note that the expression entries must
 start at the left margin, no whitespace is allowed before them, as seen
 in the following segment of an Org file:(2)
 
      * Holidays
        :PROPERTIES:
        :CATEGORY: Holiday
        :END:
      %%(org-calendar-holiday)   ; special function for holiday names
 
      * Birthdays
        :PROPERTIES:
        :CATEGORY: Ann
        :END:
      %%(org-anniversary 1956  5 14) Arthur Dent is %d years old
      %%(org-anniversary 1869 10  2) Mahatma Gandhi would be %d years old
 
 Anniversaries from BBDB
 .......................
 
 If you are using the Insidious Big Brother Database to store your
 contacts, you very likely prefer to store anniversaries in BBDB rather
 than in a separate Org or diary file.  Org supports this and can show
 BBDB anniversaries as part of the agenda.  All you need to do is to add
 the following to one of your agenda files:
 
      * Anniversaries
        :PROPERTIES:
        :CATEGORY: Anniv
        :END:
      %%(org-bbdb-anniversaries)
 
    You can then go ahead and define anniversaries for a BBDB record.
 Basically, you need a field named ‘anniversary’ for the BBDB record
 which contains the date in the format ‘YYYY-MM-DD’ or ‘MM-DD’, followed
 by a space and the class of the anniversary (‘birthday’, ‘wedding’, or a
 format string).  If you omit the class, it defaults to ‘birthday’.  Here
 are a few examples, the header for the file ‘ol-bbdb.el’ contains more
 detailed information.
 
      1973-06-22
      06-22
      1955-08-02 wedding
      2008-04-14 %s released version 6.01 of Org mode, %d years ago
 
    After a change to BBDB, or for the first agenda display during an
 Emacs session, the agenda display suffers a short delay as Org updates
 its hash with anniversaries.  However, from then on things will be very
 fast, much faster in fact than a long list of ‘%%(diary-anniversary)’
 entries in an Org or Diary file.
 
    If you would like to see upcoming anniversaries with a bit of
 forewarning, you can use the following instead:
 
      * Anniversaries
        :PROPERTIES:
        :CATEGORY: Anniv
        :END:
      %%(org-bbdb-anniversaries-future 3)
 
    That will give you three days’ warning: on the anniversary date
 itself and the two days prior.  The argument is optional: if omitted, it
 defaults to 7.
 
 Appointment reminders
 .....................
 
 Org can interact with Emacs appointments notification facility.  To add
 the appointments of your agenda files, use the command
 ‘org-agenda-to-appt’.  This command lets you filter through the list of
 your appointments and add only those belonging to a specific category or
 matching a regular expression.  It also reads a ‘APPT_WARNTIME’ property
 which overrides the value of ‘appt-message-warning-time’ for this
 appointment.  See the docstring for details.
 
    ---------- Footnotes ----------
 
    (1) For backward compatibility, the universal prefix argument ‘C-u’
 causes all TODO entries to be listed before the agenda.  This feature is
 deprecated, use the dedicated TODO list, or a block agenda instead (see
 *note Block agenda::).
 
    (2) The variable ‘org-anniversary’ used in the example is just like
 ‘diary-anniversary’, but the argument order is always according to ISO
 and therefore independent of the value of ‘calendar-date-style’.
 
 
 File: org.info,  Node: Global TODO list,  Next: Matching tags and properties,  Prev: Weekly/daily agenda,  Up: Built-in Agenda Views
 
 11.3.2 The global TODO list
 ---------------------------
 
 The global TODO list contains all unfinished TODO items formatted and
 collected into a single place.
 
 ‘M-x org-agenda t’ (‘org-todo-list’)
      Show the global TODO list.  This collects the TODO items from all
      agenda files (see *note Agenda Views::) into a single buffer.  By
      default, this lists items with a state that is not a DONE state.
      The buffer is in Agenda mode, so there are commands to examine and
      manipulate the TODO entries directly from that buffer (see *note
      Agenda Commands::).
 
 ‘M-x org-agenda T’ (‘org-todo-list’)
      Like the above, but allows selection of a specific TODO keyword.
      You can also do this by specifying a prefix argument to ‘t’.  You
      are prompted for a keyword, and you may also specify several
      keywords by separating them with ‘|’ as the boolean OR operator.
      With a numeric prefix, the Nth keyword in ‘org-todo-keywords’ is
      selected.
 
      The ‘r’ key in the agenda buffer regenerates it, and you can give a
      prefix argument to this command to change the selected TODO
      keyword, for example ‘3 r’.  If you often need a search for a
      specific keyword, define a custom command for it (see *note Agenda
      Dispatcher::).
 
      Matching specific TODO keywords can also be done as part of a tags
      search (see *note Tag Searches::).
 
    Remote editing of TODO items means that you can change the state of a
 TODO entry with a single key press.  The commands available in the TODO
 list are described in *note Agenda Commands::.
 
    Normally the global TODO list simply shows all headlines with TODO
 keywords.  This list can become very long.  There are two ways to keep
 it more compact:
 
    • Some people view a TODO item that has been _scheduled_ for
      execution or have a _deadline_ (see *note Timestamps::) as no
      longer _open_.  Configure the variables
      ‘org-agenda-todo-ignore-scheduled’ to exclude some or all scheduled
      items from the global TODO list, ‘org-agenda-todo-ignore-deadlines’
      to exclude some or all items with a deadline set,
      ‘org-agenda-todo-ignore-timestamp’ to exclude some or all items
      with an active timestamp other than a DEADLINE or a SCHEDULED
      timestamp and/or ‘org-agenda-todo-ignore-with-date’ to exclude
      items with at least one active timestamp.
 
    • TODO items may have sublevels to break up the task into subtasks.
      In such cases it may be enough to list only the highest level TODO
      headline and omit the sublevels from the global list.  Configure
      the variable ‘org-agenda-todo-list-sublevels’ to get this behavior.
 
 
 File: org.info,  Node: Matching tags and properties,  Next: Search view,  Prev: Global TODO list,  Up: Built-in Agenda Views
 
 11.3.3 Matching tags and properties
 -----------------------------------
 
 If headlines in the agenda files are marked with _tags_ (see *note
 Tags::), or have properties (see *note Properties and Columns::), you
 can select headlines based on this metadata and collect them into an
 agenda buffer.  The match syntax described here also applies when
 creating sparse trees with ‘C-c / m’.
 
 ‘M-x org-agenda m’ (‘org-tags-view’)
      Produce a list of all headlines that match a given set of tags.
      The command prompts for a selection criterion, which is a boolean
      logic expression with tags, like ‘+work+urgent-withboss’ or
      ‘work|home’ (see *note Tags::).  If you often need a specific
      search, define a custom command for it (see *note Agenda
      Dispatcher::).
 
 ‘M-x org-agenda M’ (‘org-tags-view’)
      Like ‘m’, but only select headlines that are also TODO items.  To
      exclude scheduled/deadline items, see the variable
      ‘org-agenda-tags-todo-honor-ignore-options’.  Matching specific
      TODO keywords together with a tags match is also possible, see
      *note Tag Searches::.
 
    The commands available in the tags list are described in *note Agenda
 Commands::.
 
    A search string can use Boolean operators ‘&’ for AND and ‘|’ for OR.
 ‘&’ binds more strongly than ‘|’.  Parentheses are currently not
 implemented.  Each element in the search is either a tag, a regular
 expression matching tags, or an expression like ‘PROPERTY OPERATOR
 VALUE’ with a comparison operator, accessing a property value.  Each
 element may be preceded by ‘-’ to select against it, and ‘+’ is
 syntactic sugar for positive selection.  The AND operator ‘&’ is
 optional when ‘+’ or ‘-’ is present.  Here are some examples, using only
 tags.
 
 ‘+work-boss’
      Select headlines tagged ‘work’, but discard those also tagged
      ‘boss’.
 
 ‘work|laptop’
      Selects lines tagged ‘work’ or ‘laptop’.
 
 ‘work|laptop+night’
      Like before, but require the ‘laptop’ lines to be tagged also
      ‘night’.
 
    Instead of a tag, you may also specify a regular expression enclosed
 in curly braces (see *note Regular Expressions::).  For example,
 ‘work+{^boss.*}’ matches headlines that contain the tag ‘:work:’ and any
 tag _starting_ with ‘boss’.
 
    Group tags (see *note Tag Hierarchy::) are expanded as regular
 expressions.  E.g., if ‘work’ is a group tag for the group
 ‘:work:lab:conf:’, then searching for ‘work’ also searches for
 ‘{\(?:work\|lab\|conf\)}’ and searching for ‘-work’ searches for all
 headlines but those with one of the tags in the group (i.e.,
 ‘-{\(?:work\|lab\|conf\)}’).
 
    You may also test for properties (see *note Properties and Columns::)
 at the same time as matching tags.  The properties may be real
 properties, or special properties that represent other metadata (see
 *note Special Properties::).  For example, the property ‘TODO’
 represents the TODO keyword of the entry.  Or, the property ‘LEVEL’
 represents the level of an entry.  So searching
 ‘+LEVEL=3+boss-TODO​="DONE"’ lists all level three headlines that have
 the tag ‘boss’ and are _not_ marked with the TODO keyword ‘DONE’.  In
 buffers with ‘org-odd-levels-only’ set, ‘LEVEL’ does not count the
 number of stars, but ‘LEVEL=2’ corresponds to 3 stars etc.
 
    Here are more examples:
 
 ‘work+TODO​="WAITING"’
      Select ‘work’-tagged TODO lines with the specific TODO keyword
      ‘WAITING’.
 
 ‘work+TODO​="WAITING"|home+TODO​="WAITING"’
      Waiting tasks both at work and at home.
 
    When matching properties, a number of different operators can be used
 to test the value of a property.  Here is a complex example:
 
      +work-boss+PRIORITY="A"+Coffee="unlimited"+Effort<*2
               +With={Sarah\|Denny}+SCHEDULED>="<2008-10-11>"
 
 The type of comparison depends on how the comparison value is written:
 
    • If the comparison value is a plain number, a numerical comparison
      is done, and the allowed operators are ‘<’, ‘=’, ‘>’, ‘<=’, ‘>=’,
      and ‘<>’.  As a synonym for the equality operator ‘=’, there is
      also ‘==’; ‘!=’ and ‘/=’ are synonyms of the inequality operator
      ‘<>’.
 
    • If the comparison value is enclosed in double-quotes, a string
      comparison is done, and the same operators are allowed.
 
    • If the comparison value is enclosed in double-quotes _and_ angular
      brackets (like ‘DEADLINE<​="<2008-12-24 18:30>"’), both values are
      assumed to be date/time specifications in the standard Org way, and
      the comparison is done accordingly.  Valid values also include
      ‘"<now>"’ for now (including time), ‘"<today>"’, and ‘"<tomorrow>"’
      for these days at 0:00 hours, i.e., without a time specification.
      You can also use strings like ‘"<+5d>"’ or ‘"<-2m>"’ with units
      ‘d’, ‘w’, ‘m’, and ‘y’ for day, week, month, and year,
      respectively.
 
    • If the comparison value is enclosed in curly braces, a regexp match
      is performed, with ‘=’ meaning that the regexp matches the property
      value, and ‘<>’ meaning that it does not match.
 
    • All operators may be optionally followed by an asterisk ‘*’, like
      in ‘<*’, ‘!=*’, etc.  Such _starred operators_ work like their
      regular, unstarred counterparts except that they match only
      headlines where the tested property is actually present.  This is
      most useful for search terms that logically exclude results, like
      the inequality operator.
 
    So the search string in the example finds entries tagged ‘work’ but
 not ‘boss’, which also have a priority value ‘A’, a ‘Coffee’ property
 with the value ‘unlimited’, an ‘EFFORT’ property that is numerically
 smaller than 2, a ‘With’ property that is matched by the regular
 expression ‘Sarah\|Denny’, and that are scheduled on or after October
 11, 2008.
 
    Note that the test on the ‘EFFORT’ property uses operator ‘<*’, so
 that the search result will include only entries that actually have an
 ‘EFFORT’ property defined and with numerical value smaller than 2.  With
 the regular ‘<’ operator, the search would handle entries without an
 ‘EFFORT’ property as having a zero effort and would include them in the
 result as well.
 
    You can use all characters valid in property names when matching
 properties.  However, you have to quote some characters in property
 names with backslashes when using them in search strings, namely all
 characters different from alphanumerics and underscores(1).  For
 example, to search for all entries having a property ‘boss-prio’,
 ‘boss:prio’, or ‘boss\prio’, respectively, with value ‘C’, use search
 strings
 
      boss\-prio="C"
      boss\:prio="C"
      boss\\prio="C"
 
    You can configure Org mode to use property inheritance during a
 search, but beware that this can slow down searches considerably.  See
 *note Property Inheritance::, for details.
 
    For backward compatibility, and also for typing speed, there is also
 a different way to test TODO states in a search.  For this, terminate
 the tags/property part of the search string (which may include several
 terms connected with ‘|’) with a ‘/’ and then specify a Boolean
 expression just for TODO keywords.  The syntax is then similar to that
 for tags, but should be applied with care: for example, a positive
 selection on several TODO keywords cannot meaningfully be combined with
 boolean AND.  However, _negative selection_ combined with AND can be
 meaningful.  To make sure that only lines are checked that actually have
 any TODO keyword (resulting in a speed-up), use ‘M-x org-agenda M’, or
 equivalently start the TODO part after the slash with ‘!’.  Using ‘M-x
 org-agenda M’ or ‘/!’ does not match TODO keywords in a DONE state.
 Examples:
 
 ‘work/WAITING’
      Same as ‘work+TODO​="WAITING"’.
 
 ‘work/!-WAITING-NEXT’
      Select ‘work’-tagged TODO lines that are neither ‘WAITING’ nor
      ‘NEXT’.
 
 ‘work/!+WAITING|+NEXT’
      Select ‘work’-tagged TODO lines that are either ‘WAITING’ or
      ‘NEXT’.

 11.3.4 Search view
 ------------------
 
 This agenda view is a general text search facility for Org mode entries.
 It is particularly useful to find notes.
 
 ‘M-x org-agenda s’ (‘org-search-view’)
      This is a special search that lets you select entries by matching a
      substring or specific words using a boolean logic.
 
    For example, the search string ‘computer equipment’ matches entries
 that contain ‘computer equipment’ as a substring, even if the two words
 are separated by more space or a line break.
 
    Search view can also search for specific keywords in the entry, using
 Boolean logic.  The search string ‘+computer +wifi -ethernet
 -{8\.11[bg]}’ matches note entries that contain the keywords ‘computer’
 and ‘wifi’, but not the keyword ‘ethernet’, and which are also not
 matched by the regular expression ‘8\.11[bg]’, meaning to exclude both
 ‘8.11b’ and ‘8.11g’.  The first ‘+’ is necessary to turn on boolean
 search, other ‘+’ characters are optional.  For more details, see the
 docstring of the command ‘org-search-view’.
 
    You can incrementally and conveniently adjust a boolean search from
 the agenda search view with the following keys
 
 ‘[’     Add a positive search word
 ‘]’     Add a negative search word
 ‘{’     Add a positive regular expression
 ‘}’     Add a negative regular expression
 
    Note that in addition to the agenda files, this command also searches
 the files listed in ‘org-agenda-text-search-extra-files’.

 11.3.5 Stuck projects
 ---------------------
 
 If you are following a system like David Allen’s GTD to organize your
 work, one of the “duties” you have is a regular review to make sure that
 all projects move along.  A _stuck_ project is a project that has no
 defined next actions, so it never shows up in the TODO lists Org mode
 produces.  During the review, you need to identify such projects and
 define next actions for them.
 
 ‘M-x org-agenda #’ (‘org-agenda-list-stuck-projects’)
      List projects that are stuck.
 
 ‘M-x org-agenda !’
      Customize the variable ‘org-stuck-projects’ to define what a stuck
      project is and how to find it.
 
    You almost certainly need to configure this view before it works for
 you.  The built-in default assumes that all your projects are level-2
 headlines, and that a project is not stuck if it has at least one entry
 marked with a TODO keyword ‘TODO’ or ‘NEXT’ or ‘NEXTACTION’.
 
    Let’s assume that you, in your own way of using Org mode, identify
 projects with a tag ‘:PROJECT:’, and that you use a TODO keyword ‘MAYBE’
 to indicate a project that should not be considered yet.  Let’s further
 assume that the TODO keyword ‘DONE’ marks finished projects, and that
 ‘NEXT’ and ‘TODO’ indicate next actions.  The tag ‘:@shop:’ indicates
 shopping and is a next action even without the NEXT tag.  Finally, if
 the project contains the special word ‘IGNORE’ anywhere, it should not
 be listed either.  In this case you would start by identifying eligible
 projects with a tags/TODO match (see *note Tag Searches::)
 ‘+PROJECT/-MAYBE-DONE’, and then check for ‘TODO’, ‘NEXT’, ‘@shop’, and
 ‘IGNORE’ in the subtree to identify projects that are not stuck.  The
 correct customization for this is:
 
      (setq org-stuck-projects
            '("+PROJECT/-MAYBE-DONE" ("NEXT" "TODO") ("@shop")
              "\\<IGNORE\\>"))
 
    Note that if a project is identified as non-stuck, the subtree of
 this entry is searched for stuck projects.

 11.4 Presentation and Sorting
 =============================
 
 Before displaying items in an agenda view, Org mode visually prepares
 the items and sorts them.  Each item occupies a single line.  The line
 starts with a _prefix_ that contains the _category_ (see *note
 Categories::) of the item and other important information.  You can
 customize in which column tags are displayed through
 ‘org-agenda-tags-column’.  You can also customize the prefix using the
 option ‘org-agenda-prefix-format’.  This prefix is followed by a
 cleaned-up version of the outline headline associated with the item.
 
 * Menu:
 
 * Categories::                   Not all tasks are equal.
 * Time-of-day specifications::   How the agenda knows the time.
 * Sorting of agenda items::      The order of things.
 * Filtering/limiting agenda items:: Dynamically narrow the agenda.
 
 
 File: org.info,  Node: Categories,  Next: Time-of-day specifications,  Up: Presentation and Sorting
 
 11.4.1 Categories
 -----------------
 
 The category is a broad label assigned to each agenda item.  By default,
 the category is simply derived from the file name, but you can also
 specify it with a special line in the buffer, like this:
 
      #+CATEGORY: Thesis
 
    If you would like to have a special category for a single entry or a
 (sub)tree, give the entry a ‘CATEGORY’ property with the special
 category you want to apply as the value.
 
    The display in the agenda buffer looks best if the category is not
 longer than 10 characters.  You can set up icons for category by
 customizing the ‘org-agenda-category-icon-alist’ variable.
 
 
 File: org.info,  Node: Time-of-day specifications,  Next: Sorting of agenda items,  Prev: Categories,  Up: Presentation and Sorting
 
 11.4.2 Time-of-day specifications
 ---------------------------------
 
 Org mode checks each agenda item for a time-of-day specification.  The
 time can be part of the timestamp that triggered inclusion into the
 agenda, for example
 
      <2005-05-10 Tue 19:00>
 
 Time ranges can be specified with two timestamps:
 
      <2005-05-10 Tue 20:30>--<2005-05-10 Tue 22:15>
 
    In the headline of the entry itself, a time(range)—like ‘12:45’ or a
 ‘8:30-1pm’—may also appear as plain text(1).
 
    If the agenda integrates the Emacs diary (see *note Weekly/daily
 agenda::), time specifications in diary entries are recognized as well.
 
    For agenda display, Org mode extracts the time and displays it in a
 standard 24 hour format as part of the prefix.  The example times in the
 previous paragraphs would end up in the agenda like this:
 
       8:30-13:00 Arthur Dent lies in front of the bulldozer
      12:45...... Ford Prefect arrives and takes Arthur to the pub
      19:00...... The Vogon reads his poem
      20:30-22:15 Marvin escorts the Hitchhikers to the bridge
 
    If the agenda is in single-day mode, or for the display of today, the
 timed entries are embedded in a time grid, like
 
       8:00...... ------------------
       8:30-13:00 Arthur Dent lies in front of the bulldozer
      10:00...... ------------------
      12:00...... ------------------
      12:45...... Ford Prefect arrives and takes Arthur to the pub
      14:00...... ------------------
      16:00...... ------------------
      18:00...... ------------------
      19:00...... The Vogon reads his poem
      20:00...... ------------------
      20:30-22:15 Marvin escorts the Hitchhikers to the bridge
 
    The time grid can be turned on and off with the variable
 ‘org-agenda-use-time-grid’, and can be configured with
 ‘org-agenda-time-grid’.
 
    ---------- Footnotes ----------
 
    (1) You can, however, disable this by setting
 ‘org-agenda-search-headline-for-time’ variable to a ‘nil’ value.

 11.4.3 Sorting of agenda items
 ------------------------------
 
 Before being inserted into a view, the items are sorted.  How this is
 done depends on the type of view.
 
    • For the daily/weekly agenda, the items for each day are sorted.
      The default order is to first collect all items containing an
      explicit time-of-day specification.  These entries are shown at the
      beginning of the list, as a _schedule_ for the day.  After that,
      items remain grouped in categories, in the sequence given by
      ‘org-agenda-files’.  Within each category, items are sorted by
      urgency, which is composed of the base priority (see *note
      Priorities::; 2000 for priority ‘A’, 1000 for ‘B’, and 0 for ‘C’),
      plus additional increments for overdue scheduled or deadline items.
 
    • For the TODO list, items remain in the order of categories, but
      within each category, sorting takes place according to urgency.
      The urgency used for sorting derives from the priority cookie, with
      additions depending on how close an item is to its due or scheduled
      date.
 
    • For tags matches, items are not sorted at all, but just appear in
      the sequence in which they are found in the agenda files.
 
    Sorting can be customized using the variable
 ‘org-agenda-sorting-strategy’, and may also include criteria based on
 the estimated effort of an entry (see *note Effort Estimates::).

 11.4.4 Filtering/limiting agenda items
 --------------------------------------
 
 Agenda built-in or custom commands are statically defined.  Agenda
 filters and limits allow flexibly narrowing down the list of agenda
 entries.
 
    _Filters_ only change the visibility of items, are very fast and are
 mostly used interactively(1).  You can switch quickly between different
 filters without having to recreate the agenda.  _Limits_ on the other
 hand take effect before the agenda buffer is populated, so they are
 mostly useful when defined as local variables within custom agenda
 commands.
 
 Filtering in the agenda
 .......................
 
 The general filtering command is ‘org-agenda-filter’, bound to ‘/’.
 Before we introduce it, we describe commands for individual filter
 types.  All filtering commands handle prefix arguments in the same way:
 A single ‘C-u’ prefix negates the filter, so it removes lines selected
 by the filter.  A double prefix adds the new filter condition to the
 one(s) already in place, so filter elements are accumulated.
 
 ‘\’ (‘org-agenda-filter-by-tag’)
      Filter the agenda view with respect to a tag.  You are prompted for
      a tag selection letter; ‘<SPC>’ means any tag at all.  Pressing
      ‘<TAB>’ at that prompt offers completion to select a tag, including
      any tags that do not have a selection character.  The command then
      hides all entries that do not contain or inherit this tag.
      Pressing ‘+’ or ‘-’ at the prompt switches between filtering for
      and against the next tag.  To clear the filter, press ‘\’ twice
      (once to call the command again, and once at the prompt).
 
 ‘<’ (‘org-agenda-filter-by-category’)
      Filter by category of the line at point, and show only entries with
      this category.  When called with a prefix argument, hide all
      entries with the category at point.  To clear the filter, call this
      command again by pressing ‘<’.
 
 ‘=’ (‘org-agenda-filter-by-regexp’)
      Filter the agenda view by a regular expression: only show agenda
      entries matching the regular expression the user entered.  To clear
      the filter, call the command again by pressing ‘=’.
 
 ‘_’ (‘org-agenda-filter-by-effort’)
      Filter the agenda view with respect to effort estimates, so select
      tasks that take the right amount of time.  You first need to set up
      a list of efforts globally, for example
 
           (setq org-global-properties
                 '(("Effort_ALL". "0 0:10 0:30 1:00 2:00 3:00 4:00")))
 
      You can then filter for an effort by first typing an operator, one
      of ‘<’, ‘>’ and ‘=’, and then the one-digit index of an effort
      estimate in your array of allowed values, where ‘0’ means the 10th
      value.  The filter then restricts to entries with effort
      smaller-or-equal, equal, or larger-or-equal than the selected
      value.  For application of the operator, entries without a defined
      effort are treated according to the value of
      ‘org-sort-agenda-noeffort-is-high’.  To clear the filter, press ‘_’
      twice (once to call the command again, and once at the first
      prompt).
 
 ‘^’ (‘org-agenda-filter-by-top-headline’)
      Filter the current agenda view and only display items that fall
      under the same top-level headline as the current entry.  To clear
      the filter, call this command again by pressing ‘^’.
 
 ‘/’ (‘org-agenda-filter’)
      This is the unified interface to four of the five filter methods
      described above.  At the prompt, specify different filter elements
      in a single string, with full completion support.  For example,
 
           +work-John+<0:10-/plot/
 
      selects entries with category ‘work’ and effort estimates below 10
      minutes, and deselects entries with tag ‘John’ or matching the
      regexp ‘plot’ (see *note Regular Expressions::).  You can leave ‘+’
      out if that does not lead to ambiguities.  The sequence of elements
      is arbitrary.  The filter syntax assumes that there is no overlap
      between categories and tags.  Otherwise, tags take priority.  If
      you reply to the prompt with the empty string, all filtering is
      removed.  If a filter is specified, it replaces all current
      filters.  But if you call the command with a double prefix
      argument, or if you add an additional ‘+’ (e.g., ‘++work’) to the
      front of the string, the new filter elements are added to the
      active ones.  A single prefix argument applies the entire filter in
      a negative sense.
 
 ‘|’ (‘org-agenda-filter-remove-all’)
      Remove all filters in the current agenda view.
 
 Computed tag filtering
 ......................
 
 If the variable ‘org-agenda-auto-exclude-function’ is set to a
 user-defined function, that function can select tags that should be used
 as a tag filter when requested.  The function will be called with
 lower-case versions of all tags represented in the current view.  The
 function should return ‘"-tag"’ if the filter should remove entries with
 that tag, ‘"+tag"’ if only entries with this tag should be kept, or
 ‘nil’ if that tag is irrelevant.  For example, let’s say you use a ‘Net’
 tag to identify tasks which need network access, an ‘Errand’ tag for
 errands in town, and a ‘Call’ tag for making phone calls.  You could
 auto-exclude these tags based on the availability of the Internet, and
 outside of business hours, with something like this:
 
      (defun my-auto-exclude-fn (tag)
        (when (cond ((string= tag "net")
                     (/= 0 (call-process "/sbin/ping" nil nil nil
                                         "-c1" "-q" "-t1" "mail.gnu.org")))
                    ((member tag '("errand" "call"))
                     (let ((hr (nth 2 (decode-time))))
                       (or (< hr 8) (> hr 21)))))
          (concat "-" tag)))
 
      (setq org-agenda-auto-exclude-function #'my-auto-exclude-fn)
 
    You can apply this self-adapting filter by using a triple prefix
 argument to ‘org-agenda-filter’, i.e. press ‘C-u C-u C-u /’, or by
 pressing ‘<RET>’ in ‘org-agenda-filter-by-tag’.
 
 Setting limits for the agenda
 .............................
 
 Here is a list of options that you can set, either globally, or locally
 in your custom agenda views (see *note Custom Agenda Views::).
 
 ‘org-agenda-max-entries’
      Limit the number of entries.
 
 ‘org-agenda-max-effort’
      Limit the duration of accumulated efforts (as minutes).
 
 ‘org-agenda-max-todos’
      Limit the number of entries with TODO keywords.
 
 ‘org-agenda-max-tags’
      Limit the number of tagged entries.
 
    When set to a positive integer, each option excludes entries from
 other categories: for example, ‘(setq org-agenda-max-effort 100)’ limits
 the agenda to 100 minutes of effort and exclude any entry that has no
 effort property.  If you want to include entries with no effort
 property, use a negative value for ‘org-agenda-max-effort’.  One useful
 setup is to use ‘org-agenda-max-entries’ locally in a custom command.
 For example, this custom command displays the next five entries with a
 ‘NEXT’ TODO keyword.
 
      (setq org-agenda-custom-commands
            '(("n" todo "NEXT"
               ((org-agenda-max-entries 5)))))
 
    Once you mark one of these five entry as DONE, rebuilding the agenda
 will again the next five entries again, including the first entry that
 was excluded so far.
 
    You can also dynamically set temporary limits, which are lost when
 rebuilding the agenda:
 
 ‘~’ (‘org-agenda-limit-interactively’)
      This prompts for the type of limit to apply and its value.
 
    ---------- Footnotes ----------
 
    (1) Custom agenda commands can preset a filter by binding one of the
 variables ‘org-agenda-tag-filter-preset’,
 ‘org-agenda-category-filter-preset’, ‘org-agenda-effort-filter-preset’
 or ‘org-agenda-regexp-filter-preset’ as an option.  This filter is then
 applied to the view and persists as a basic filter through refreshes and
 more secondary filtering.  The filter is a global property of the entire
 agenda view—in a block agenda, you should only set this in the global
 options section, not in the section of an individual block.

 11.5 Commands in the Agenda Buffer
 ==================================
 
 Entries in the agenda buffer are linked back to the Org file or diary
 file where they originate.  You are not allowed to edit the agenda
 buffer itself, but commands are provided to show and jump to the
 original entry location, and to edit the Org files “remotely” from the
 agenda buffer.  In this way, all information is stored only once,
 removing the risk that your agenda and note files may diverge.
 
    Some commands can be executed with mouse clicks on agenda lines.  For
 the other commands, point needs to be in the desired line.
 
 Motion
 ------
 
 ‘n’ (‘org-agenda-next-line’)
      Next line (same as ‘<DOWN>’ and ‘C-n’).
 
 ‘p’ (‘org-agenda-previous-line’)
      Previous line (same as ‘<UP>’ and ‘C-p’).
 
 View/Go to Org file
 -------------------
 
 ‘<SPC>’ or ‘mouse-3’ (‘org-agenda-show-and-scroll-up’)
      Display the original location of the item in another window.  With
      a prefix argument, make sure that drawers stay folded.
 
 ‘L’ (‘org-agenda-recenter’)
      Display original location and recenter that window.
 
 ‘<TAB>’ or ‘mouse-2’ (‘org-agenda-goto’)
      Go to the original location of the item in another window.
 
 ‘<RET>’ (‘org-agenda-switch-to’)
      Go to the original location of the item and delete other windows.
 
 ‘F’ (‘org-agenda-follow-mode’)
      Toggle Follow mode.  In Follow mode, as you move point through the
      agenda buffer, the other window always shows the corresponding
      location in the Org file.  The initial setting for this mode in new
      agenda buffers can be set with the variable
      ‘org-agenda-start-with-follow-mode’.
 
 ‘C-c C-x b’ (‘org-agenda-tree-to-indirect-buffer’)
      Display the entire subtree of the current item in an indirect
      buffer.  With a numeric prefix argument N, go up to level N and
      then take that tree.  If N is negative, go up that many levels.
      With a ‘C-u’ prefix, do not remove the previously used indirect
      buffer.
 
 ‘C-c C-o’ (‘org-agenda-open-link’)
      Follow a link in the entry.  This offers a selection of any links
      in the text belonging to the referenced Org node.  If there is only
      one link, follow it without a selection prompt.
 
 Change display
 --------------
 
 ‘A’
      Interactively select another agenda view and append it to the
      current view.
 
 ‘o’
      Delete other windows.
 
 ‘v d’ or short ‘d’ (‘org-agenda-day-view’)
      Switch to day view.  When switching to day view, this setting
      becomes the default for subsequent agenda refreshes.  A numeric
      prefix argument may be used to jump directly to a specific day of
      the year.  For example, ‘32 d’ jumps to February 1st.  When setting
      day view, a year may be encoded in the prefix argument as well.
      For example, ‘200712 d’ jumps to January 12, 2007.  If such a year
      specification has only one or two digits, it is expanded into one
      of the 30 next years or the last 69 years.
 
 ‘v w’ or short ‘w’ (‘org-agenda-week-view’)
      Switch to week view.  When switching week view, this setting
      becomes the default for subsequent agenda refreshes.  A numeric
      prefix argument may be used to jump directly to a specific day of
      the ISO week.  For example ‘9 w’ to ISO week number 9.  When
      setting week view, a year may be encoded in the prefix argument as
      well.  For example, ‘200712 w’ jumps to week 12 in 2007.  If such a
      year specification has only one or two digits, it is expanded into
      one of the 30 next years or the last 69 years.
 
 ‘v m’ (‘org-agenda-month-view’)
      Switch to month view.  Because month views are slow to create, they
      do not become the default for subsequent agenda refreshes.  A
      numeric prefix argument may be used to jump directly to a specific
      day of the month.  When setting month view, a year may be encoded
      in the prefix argument as well.  For example, ‘200712 m’ jumps to
      December, 2007.  If such a year specification has only one or two
      digits, it is expanded into one of the 30 next years or the last 69
      years.
 
 ‘v y’ (‘org-agenda-year-view’)
      Switch to year view.  Because year views are slow to create, they
      do not become the default for subsequent agenda refreshes.  A
      numeric prefix argument may be used to jump directly to a specific
      day of the year.
 
 ‘v <SPC>’ (‘org-agenda-reset-view’)
      Reset the current view to ‘org-agenda-span’.
 
 ‘f’ (‘org-agenda-later’)
      Go forward in time to display the span following the current one.
      For example, if the display covers a week, switch to the following
      week.  With a prefix argument, repeat that many times.
 
 ‘b’ (‘org-agenda-earlier’)
      Go backward in time to display earlier dates.
 
 ‘.’ (‘org-agenda-goto-today’)
      Go to today.
 
 ‘j’ (‘org-agenda-goto-date’)
      Prompt for a date and go there.
 
 ‘J’ (‘org-agenda-clock-goto’)
      Go to the currently clocked-in task _in the agenda buffer_.
 
 ‘D’ (‘org-agenda-toggle-diary’)
      Toggle the inclusion of diary entries.  See *note Weekly/daily
      agenda::.
 
 ‘v l’ or ‘v L’ or short ‘l’ (‘org-agenda-log-mode’)
      Toggle Logbook mode.  In Logbook mode, entries that were marked as
      done while logging was on (see the variable ‘org-log-done’) are
      shown in the agenda, as are entries that have been clocked on that
      day.  You can configure the entry types that should be included in
      log mode using the variable ‘org-agenda-log-mode-items’.  When
      called with a ‘C-u’ prefix argument, show all possible logbook
      entries, including state changes.  When called with two prefix
      arguments ‘C-u C-u’, show only logging information, nothing else.
      ‘v L’ is equivalent to ‘C-u v l’.
 
 ‘v [’ or short ‘[’ (‘org-agenda-manipulate-query-add’)
      Include inactive timestamps into the current view.  Only for
      weekly/daily agenda.
 
 ‘v a’ (‘org-agenda-archives-mode’)
      Toggle Archives mode.  In Archives mode, trees that are archived
      (see *note Internal archiving::) are also scanned when producing
      the agenda.  To exit archives mode, press ‘v a’ again.  The initial
      setting for this mode in new agenda buffers can set with the
      variable ‘org-agenda-start-with-archives-mode’, which can be set
      with the same values as ‘org-agenda-archives-mode’.
 
 ‘v A’
      Toggle Archives mode.  Include all archive files as well.
 
 ‘v R’ or short ‘R’ (‘org-agenda-clockreport-mode’)
      Toggle Clockreport mode.  In Clockreport mode, the daily/weekly
      agenda always shows a table with the clocked times for the time
      span and file scope covered by the current agenda view.  The
      initial setting for this mode in new agenda buffers can be set with
      the variable ‘org-agenda-start-with-clockreport-mode’.  By using a
      prefix argument when toggling this mode (i.e., ‘C-u R’), the clock
      table does not show contributions from entries that are hidden by
      agenda filtering(1).  See also the variables
      ‘org-clock-report-include-clocking-task’ and
      ‘org-agenda-clock-report-header’.
 
 ‘v c’
      Show overlapping clock entries, clocking gaps, and other clocking
      problems in the current agenda range.  You can then visit clocking
      lines and fix them manually.  See the variable
      ‘org-agenda-clock-consistency-checks’ for information on how to
      customize the definition of what constituted a clocking problem.
      To return to normal agenda display, press ‘l’ to exit Logbook mode.
 
 ‘v E’ or short ‘E’ (‘org-agenda-entry-text-mode’)
      Toggle entry text mode.  In entry text mode, a number of lines from
      the Org outline node referenced by an agenda line are displayed
      below the line.  The maximum number of lines is given by the
      variable ‘org-agenda-entry-text-maxlines’.  Calling this command
      with a numeric prefix argument temporarily modifies that number to
      the prefix value.
 
 ‘G’ (‘org-agenda-toggle-time-grid’)
      Toggle the time grid on and off.  See also the variables
      ‘org-agenda-use-time-grid’ and ‘org-agenda-time-grid’.
 
 ‘r’ (‘org-agenda-redo’)
 ‘g’
      Recreate the agenda buffer, for example to reflect the changes
      after modification of the timestamps of items with ‘S-<LEFT>’ and
      ‘S-<RIGHT>’.  When the buffer is the global TODO list, a prefix
      argument is interpreted to create a selective list for a specific
      TODO keyword.
 
 ‘C-x C-s’ or short ‘s’ (‘org-save-all-org-buffers’)
      Save all Org buffers in the current Emacs session, and also the
      locations of IDs.
 
 ‘C-c C-x C-c’ (‘org-agenda-columns’)
      Invoke column view (see *note Column View::) in the agenda buffer.
      The column view format is taken from the entry at point, or, if
      there is no entry at point, from the first entry in the agenda
      view.  So whatever the format for that entry would be in the
      original buffer (taken from a property, from a ‘COLUMNS’ keyword,
      or from the default variable ‘org-columns-default-format’) is used
      in the agenda.
 
 ‘C-c C-x >’ (‘org-agenda-remove-restriction-lock’)
      Remove the restriction lock on the agenda, if it is currently
      restricted to a file or subtree (see *note Agenda Files::).
 
 ‘M-<UP>’ (‘org-agenda-drag-line-backward’)
      Drag the line at point backward one line.  With a numeric prefix
      argument, drag backward by that many lines.
 
      Moving agenda lines does not persist after an agenda refresh and
      does not modify the contributing Org files.
 
 ‘M-<DOWN>’ (‘org-agenda-drag-line-forward’)
      Drag the line at point forward one line.  With a numeric prefix
      argument, drag forward by that many lines.
 
 Remote editing
 --------------
 
 ‘0--9’
      Digit argument.
 
 ‘C-_’ (‘org-agenda-undo’)
      Undo a change due to a remote editing command.  The change is
      undone both in the agenda buffer and in the remote buffer.
 
 ‘t’ (‘org-agenda-todo’)
      Change the TODO state of the item, both in the agenda and in the
      original Org file.  A prefix arg is passed through to the
      ‘org-todo’ command, so for example a ‘C-u’ prefix are will trigger
      taking a note to document the state change.
 
 ‘C-S-<RIGHT>’ (‘org-agenda-todo-nextset’)
      Switch to the next set of TODO keywords.
 
 ‘C-S-<LEFT>’, ‘org-agenda-todo-previousset’
      Switch to the previous set of TODO keywords.
 
 ‘C-k’ (‘org-agenda-kill’)
      Delete the current agenda item along with the entire subtree
      belonging to it in the original Org file.  If the text to be
      deleted remotely is longer than one line, the kill needs to be
      confirmed by the user.  See variable ‘org-agenda-confirm-kill’.
 
 ‘C-c C-w’ (‘org-agenda-refile’)
      Refile the entry at point.
 
 ‘C-c C-x C-a’ or short ‘a’ (‘org-agenda-archive-default-with-confirmation’)
      Archive the subtree corresponding to the entry at point using the
      default archiving command set in ‘org-archive-default-command’.
      When using the ‘a’ key, confirmation is required.
 
 ‘C-c C-x a’ (‘org-agenda-toggle-archive-tag’)
      Toggle the archive tag (see *note Internal archiving::) for the
      current headline.
 
 ‘C-c C-x A’ (‘org-agenda-archive-to-archive-sibling’)
      Move the subtree corresponding to the current entry to its _archive
      sibling_.
 
 ‘C-c C-x C-s’ or short ‘$’ (‘org-agenda-archive’)
      Archive the subtree corresponding to the current headline.  This
      means the entry is moved to the configured archive location, most
      likely a different file.
 
 ‘T’ (‘org-agenda-show-tags’)
      Show all tags associated with the current item.  This is useful if
      you have turned off ‘org-agenda-show-inherited-tags’, but still
      want to see all tags of a headline occasionally.
 
 ‘:’ (‘org-agenda-set-tags’)
      Set tags for the current headline.  If there is an active region in
      the agenda, change a tag for all headings in the region.
 
 ‘,’ (‘org-agenda-priority’)
      Set the priority for the current item.  Org mode prompts for the
      priority character.  If you reply with ‘<SPC>’, the priority cookie
      is removed from the entry.
 
 ‘+’ or ‘S-<UP>’ (‘org-agenda-priority-up’)
      Increase the priority of the current item.  The priority is changed
      in the original buffer, but the agenda is not resorted.  Use the
      ‘r’ key for this.
 
 ‘-’ or ‘S-<DOWN>’ (‘org-agenda-priority-down’)
      Decrease the priority of the current item.
 
 ‘C-c C-x e’ or short ‘e’ (‘org-agenda-set-effort’)
      Set the effort property for the current item.
 
 ‘C-c C-z’ or short ‘z’ (‘org-agenda-add-note’)
      Add a note to the entry.  This note is recorded, and then filed to
      the same location where state change notes are put.  Depending on
      ‘org-log-into-drawer’, this may be inside a drawer.
 
 ‘C-c C-a’ (‘org-attach’)
      Dispatcher for all command related to attachments.
 
 ‘C-c C-s’ (‘org-agenda-schedule’)
      Schedule this item.  With a prefix argument, remove the scheduling
      timestamp
 
 ‘C-c C-d’ (‘org-agenda-deadline’)
      Set a deadline for this item.  With a prefix argument, remove the
      deadline.
 
 ‘S-<RIGHT>’ (‘org-agenda-do-date-later’)
      Change the timestamp associated with the current line by one day
      into the future.  If the date is in the past, the first call to
      this command moves it to today.  With a numeric prefix argument,
      change it by that many days.  For example, ‘3 6 5 S-<RIGHT>’
      changes it by a year.  With a ‘C-u’ prefix, change the time by one
      hour.  If you immediately repeat the command, it will continue to
      change hours even without the prefix argument.  With a double ‘C-u
      C-u’ prefix, do the same for changing minutes.  The stamp is
      changed in the original Org file, but the change is not directly
      reflected in the agenda buffer.  Use ‘r’ or ‘g’ to update the
      buffer.
 
 ‘S-<LEFT>’ (‘org-agenda-do-date-earlier’)
      Change the timestamp associated with the current line by one day
      into the past.
 
 ‘>’ (‘org-agenda-date-prompt’)
      Change the timestamp associated with the current line.  The key ‘>’
      has been chosen, because it is the same as ‘S-.’ on my keyboard.
 
 ‘I’ (‘org-agenda-clock-in’)
      Start the clock on the current item.  If a clock is running
      already, it is stopped first.
 
 ‘O’ (‘org-agenda-clock-out’)
      Stop the previously started clock.
 
 ‘X’ (‘org-agenda-clock-cancel’)
      Cancel the currently running clock.
 
 ‘J’ (‘org-agenda-clock-goto’)
      Jump to the running clock in another window.
 
 ‘k’ (‘org-agenda-capture’)
      Like ‘org-capture’, but use the date at point as the default date
      for the capture template.  See ‘org-capture-use-agenda-date’ to
      make this the default behavior of ‘org-capture’.
 
 Bulk remote editing selected entries
 ------------------------------------
 
 ‘m’ (‘org-agenda-bulk-mark’)
 
      Mark the entry at point for bulk action.  If there is an active
      region in the agenda, mark the entries in the region.  With numeric
      prefix argument, mark that many successive entries.
 
 ‘*’ (‘org-agenda-bulk-mark-all’)
 
      Mark all visible agenda entries for bulk action.
 
 ‘u’ (‘org-agenda-bulk-unmark’)
 
      Unmark entry for bulk action.
 
 ‘U’ (‘org-agenda-bulk-unmark-all’)
 
      Unmark all marked entries for bulk action.
 
 ‘M-m’ (‘org-agenda-bulk-toggle’)
 
      Toggle mark of the entry at point for bulk action.
 
 ‘M-*’ (‘org-agenda-bulk-toggle-all’)
 
      Toggle mark of every entry for bulk action.
 
 ‘%’ (‘org-agenda-bulk-mark-regexp’)
 
      Mark entries matching a regular expression for bulk action.
 
 ‘B’ (‘org-agenda-bulk-action’)
 
      Bulk action: act on all marked entries in the agenda.  This prompts
      for another key to select the action to be applied.  The prefix
      argument to ‘B’ is passed through to the ‘s’ and ‘d’ commands, to
      bulk-remove these special timestamps.  By default, marks are
      removed after the bulk.  If you want them to persist, set
      ‘org-agenda-bulk-persistent-marks’ to ‘t’ or hit ‘p’ at the prompt.
 
      ‘p’
           Toggle persistent marks.
 
      ‘$’
           Archive all selected entries.
 
      ‘A’
           Archive entries by moving them to their respective archive
           siblings.
 
      ‘t’
           Change TODO state.  This prompts for a single TODO keyword and
           changes the state of all selected entries, bypassing blocking
           and suppressing logging notes—but not timestamps.
 
      ‘+’
           Add a tag to all selected entries.
 
      ‘-’
           Remove a tag from all selected entries.
 
      ‘s’
           Schedule all items to a new date.  To shift existing schedule
           dates by a fixed number of days, use something starting with
           double plus at the prompt, for example ‘++8d’ or ‘++2w’.
 
      ‘d’
           Set deadline to a specific date.
 
      ‘r’
           Prompt for a single refile target and move all entries.  The
           entries are no longer in the agenda; refresh (‘g’) to bring
           them back.
 
      ‘S’
           Reschedule randomly into the coming N days.  N is prompted
           for.  With a prefix argument (‘C-u B S’), scatter only across
           weekdays.
 
      ‘f’
           Apply a function(2) to marked entries.  For example, the
           function below sets the ‘CATEGORY’ property of the entries to
           ‘web’.
 
                (defun set-category ()
                  (interactive "P")
                  (let ((marker (or (org-get-at-bol 'org-hd-marker)
                                    (org-agenda-error))))
                    (org-with-point-at marker
                      (org-back-to-heading t)
                      (org-set-property "CATEGORY" "web"))))
 
 Calendar commands
 -----------------
 
 ‘c’ (‘org-agenda-goto-calendar’)
      Open the Emacs calendar and go to the date at point in the agenda.
 
 ‘c’ (‘org-calendar-goto-agenda’)
      When in the calendar, compute and show the Org agenda for the date
      at point.
 
 ‘i’ (‘org-agenda-diary-entry’)
 
      Insert a new entry into the diary, using the date at point and (for
      block entries) the date at the mark.  This adds to the Emacs diary
      file(3), in a way similar to the ‘i’ command in the calendar.  The
      diary file pops up in another window, where you can add the entry.
 
      If you configure ‘org-agenda-diary-file’ to point to an Org file,
      Org creates entries in that file instead.  Most entries are stored
      in a date-based outline tree that will later make it easy to
      archive appointments from previous months/years.  The tree is built
      under an entry with a ‘DATE_TREE’ property, or else with years as
      top-level entries.  Emacs prompts you for the entry text—if you
      specify it, the entry is created in ‘org-agenda-diary-file’ without
      further interaction.  If you directly press ‘<RET>’ at the prompt
      without typing text, the target file is shown in another window for
      you to finish the entry there.  See also the ‘k r’ command.
 
 ‘M’ (‘org-agenda-phases-of-moon’)
      Show the phases of the moon for the three months around current
      date.
 
 ‘S’ (‘org-agenda-sunrise-sunset’)
      Show sunrise and sunset times.  The geographical location must be
      set with calendar variables, see the documentation for the Emacs
      calendar.
 
 ‘C’ (‘org-agenda-convert-date’)
      Convert the date at point into many other cultural and historic
      calendars.
 
 ‘H’ (‘org-agenda-holidays’)
      Show holidays for three months around point date.
 
 Quit and exit
 -------------
 
 ‘q’ (‘org-agenda-quit’)
 
      Quit agenda, remove the agenda buffer.
 
 ‘x’ (‘org-agenda-exit’)
 
      Exit agenda, remove the agenda buffer and all buffers loaded by
      Emacs for the compilation of the agenda.  Buffers created by the
      user to visit Org files are not removed.
 
    ---------- Footnotes ----------
 
    (1) Only tags filtering is respected here, effort filtering is
 ignored.
 
    (2) You can also create persistent custom functions through
 ‘org-agenda-bulk-custom-functions’.

 11.6 Custom Agenda Views
 ========================
 
 Custom agenda commands serve two purposes: to store and quickly access
 frequently used TODO and tags searches, and to create special composite
 agenda buffers.  Custom agenda commands are accessible through the
 dispatcher (see *note Agenda Dispatcher::), just like the default
 commands.
 
 * Menu:
 
 * Storing searches::             Type once, use often.
 * Block agenda::                 All the stuff you need in a single buffer.
 * Setting options::              Changing the rules.
 
 
 File: org.info,  Node: Storing searches,  Next: Block agenda,  Up: Custom Agenda Views
 
 11.6.1 Storing searches
 -----------------------
 
 The first application of custom searches is the definition of keyboard
 shortcuts for frequently used searches, either creating an agenda
 buffer, or a sparse tree (the latter covering of course only the current
 buffer).
 
    Custom commands are configured in the variable
 ‘org-agenda-custom-commands’.  You can customize this variable, for
 example by pressing ‘C’ from the agenda dispatcher (see *note Agenda
 Dispatcher::).  You can also directly set it with Emacs Lisp in the
 Emacs init file.  The following example contains all valid agenda views:
 
      (setq org-agenda-custom-commands
            '(("x" agenda)
              ("y" agenda*)
              ("w" todo "WAITING")
              ("W" todo-tree "WAITING")
              ("u" tags "+boss-urgent")
              ("v" tags-todo "+boss-urgent")
              ("U" tags-tree "+boss-urgent")
              ("f" occur-tree "\\<FIXME\\>")
              ("h" . "HOME+Name tags searches") ;description for "h" prefix
              ("hl" tags "+home+Lisa")
              ("hp" tags "+home+Peter")
              ("hk" tags "+home+Kim")))
 
    The initial string in each entry defines the keys you have to press
 after the dispatcher command in order to access the command.  Usually
 this is just a single character, but if you have many similar commands,
 you can also define two-letter combinations where the first character is
 the same in several combinations and serves as a prefix key(1).  The
 second parameter is the search type, followed by the string or regular
 expression to be used for the matching.  The example above will
 therefore define:
 
 ‘x’
      as a global search for agenda entries planned(2) this week/day.
 
 ‘y’
      as the same search, but only for entries with an hour specification
      like ‘[h]h:mm’—think of them as appointments.
 
 ‘w’
      as a global search for TODO entries with ‘WAITING’ as the TODO
      keyword.
 
 ‘W’
      as the same search, but only in the current buffer and displaying
      the results as a sparse tree.
 
 ‘u’
      as a global tags search for headlines tagged ‘boss’ but not
      ‘urgent’.
 
 ‘v’
      The same search, but limiting it to headlines that are also TODO
      items.
 
 ‘U’
      as the same search, but only in the current buffer and displaying
      the result as a sparse tree.
 
 ‘f’
      to create a sparse tree (again, current buffer only) with all
      entries containing the word ‘FIXME’.
 
 ‘h’
      as a prefix command for a ‘HOME’ tags search where you have to
      press an additional key (‘l’, ‘p’ or ‘k’) to select a name (Lisa,
      Peter, or Kim) as additional tag to match.
 
    Note that ‘*-tree’ agenda views need to be called from an Org buffer
 as they operate on the current buffer only.
 
    ---------- Footnotes ----------
 
    (1) You can provide a description for a prefix key by inserting a
 cons cell with the prefix and the description.
 
    (2) _Planned_ means here that these entries have some planning
 information attached to them, like a timestamp, a scheduled or a
 deadline string.  See ‘org-agenda-entry-types’ on how to set what
 planning information is taken into account.
 
 
 File: org.info,  Node: Block agenda,  Next: Setting options,  Prev: Storing searches,  Up: Custom Agenda Views
 
 11.6.2 Block agenda
 -------------------
 
 Another possibility is the construction of agenda views that comprise
 the results of _several_ commands, each of which creates a block in the
 agenda buffer.  The available commands include ‘agenda’ for the daily or
 weekly agenda (as created with ‘a’) , ‘alltodo’ for the global TODO list
 (as constructed with ‘t’), ‘stuck’ for the list of stuck projects (as
 obtained with ‘#’) and the matching commands discussed above: ‘todo’,
 ‘tags’, and ‘tags-todo’.
 
    Here are two examples:
 
      (setq org-agenda-custom-commands
            '(("h" "Agenda and Home-related tasks"
               ((agenda "")
                (tags-todo "home")
                (tags "garden")))
              ("o" "Agenda and Office-related tasks"
               ((agenda "")
                (tags-todo "work")
                (tags "office")))))
 
 This defines ‘h’ to create a multi-block view for stuff you need to
 attend to at home.  The resulting agenda buffer contains your agenda for
 the current week, all TODO items that carry the tag ‘home’, and also all
 lines tagged with ‘garden’.  Finally the command ‘o’ provides a similar
 view for office tasks.
 
 
 File: org.info,  Node: Setting options,  Prev: Block agenda,  Up: Custom Agenda Views
 
 11.6.3 Setting options for custom commands
 ------------------------------------------
 
 Org mode contains a number of variables regulating agenda construction
 and display.  The global variables define the behavior for all agenda
 commands, including the custom commands.  However, if you want to change
 some settings just for a single custom view, you can do so.  Setting
 options requires inserting a list of variable names and values at the
 right spot in ‘org-agenda-custom-commands’.  For example:
 
      (setq org-agenda-custom-commands
            '(("w" todo "WAITING"
               ((org-agenda-sorting-strategy '(priority-down))
                (org-agenda-prefix-format "  Mixed: ")))
              ("U" tags-tree "+boss-urgent"
               ((org-show-context-detail 'minimal)))
              ("N" search ""
               ((org-agenda-files '("~org/notes.org"))
                (org-agenda-text-search-extra-files nil)))))
 
 Now the ‘w’ command sorts the collected entries only by priority, and
 the prefix format is modified to just say ‘Mixed:’ instead of giving the
 category of the entry.  The sparse tags tree of ‘U’ now turns out
 ultra-compact, because neither the headline hierarchy above the match,
 nor the headline following the match are shown.  The command ‘N’ does a
 text search limited to only a single file.
 
    For command sets creating a block agenda,
 ‘org-agenda-custom-commands’ has two separate spots for setting options.
 You can add options that should be valid for just a single command in
 the set, and options that should be valid for all commands in the set.
 The former are just added to the command entry; the latter must come
 after the list of command entries.  Going back to the block agenda
 example (see *note Block agenda::), let’s change the sorting strategy
 for the ‘h’ commands to ‘priority-down’, but let’s sort the results for
 ‘garden’ tags query in the opposite order, ‘priority-up’.  This would
 look like this:
 
      (setq org-agenda-custom-commands
            '(("h" "Agenda and Home-related tasks"
               ((agenda)
                (tags-todo "home")
                (tags "garden"
                      ((org-agenda-sorting-strategy '(priority-up)))))
               ((org-agenda-sorting-strategy '(priority-down))))
              ("o" "Agenda and Office-related tasks"
               ((agenda)
                (tags-todo "work")
                (tags "office")))))
 
    As you see, the values and parentheses setting is a little complex.
 When in doubt, use the customize interface to set this variable—it fully
 supports its structure.  Just one caveat: when setting options in this
 interface, the _values_ are just Lisp expressions.  So if the value is a
 string, you need to add the double-quotes around the value yourself.
 
    To control whether an agenda command should be accessible from a
 specific context, you can customize
 ‘org-agenda-custom-commands-contexts’.  Let’s say for example that you
 have an agenda command ‘o’ displaying a view that you only need when
 reading emails.  Then you would configure this option like this:
 
      (setq org-agenda-custom-commands-contexts
            '(("o" (in-mode . "message-mode"))))
 
    You can also tell that the command key ‘o’ should refer to another
 command key ‘r’.  In that case, add this command key like this:
 
      (setq org-agenda-custom-commands-contexts
            '(("o" "r" (in-mode . "message-mode"))))
 
    See the docstring of the variable for more information.

 11.7 Exporting Agenda Views
 ===========================
 
 If you are away from your computer, it can be very useful to have a
 printed version of some agenda views to carry around.  Org mode can
 export custom agenda views as plain text, HTML(1), Postscript, PDF(2),
 and iCalendar files.  If you want to do this only occasionally, use the
 following command:
 
 ‘C-x C-w’ (‘org-agenda-write’)
 
      Write the agenda view to a file.
 
    If you need to export certain agenda views frequently, you can
 associate any custom agenda command with a list of output file names(3).
 Here is an example that first defines custom commands for the agenda and
 the global TODO list, together with a number of files to which to export
 them.  Then we define two block agenda commands and specify file names
 for them as well.  File names can be relative to the current working
 directory, or absolute.
 
      (setq org-agenda-custom-commands
            '(("X" agenda "" nil ("agenda.html" "agenda.ps"))
              ("Y" alltodo "" nil ("todo.html" "todo.txt" "todo.ps"))
              ("h" "Agenda and Home-related tasks"
               ((agenda "")
                (tags-todo "home")
                (tags "garden"))
               nil
               ("~/views/home.html"))
              ("o" "Agenda and Office-related tasks"
               ((agenda)
                (tags-todo "work")
                (tags "office"))
               nil
               ("~/views/office.ps" "~/calendars/office.ics"))))
 
    The extension of the file name determines the type of export.  If it
 is ‘.html’, Org mode uses the htmlize package to convert the buffer to
 HTML and save it to this file name.  If the extension is ‘.ps’,
 ‘ps-print-buffer-with-faces’ is used to produce Postscript output.  If
 the extension is ‘.ics’, iCalendar export is run export over all files
 that were used to construct the agenda, and limit the export to entries
 listed in the agenda.  Any other extension produces a plain ASCII file.
 
    The export files are _not_ created when you use one of those commands
 interactively because this might use too much overhead.  Instead, there
 is a special command to produce _all_ specified files in one step:
 
 ‘e’ (‘org-store-agenda-views’)
      Export all agenda views that have export file names associated with
      them.
 
    You can use the options section of the custom agenda commands to also
 set options for the export commands.  For example:
 
      (setq org-agenda-custom-commands
            '(("X" agenda ""
               ((ps-number-of-columns 2)
                (ps-landscape-mode t)
                (org-agenda-prefix-format " [ ] ")
                (org-agenda-with-colors nil)
                (org-agenda-remove-tags t))
               ("theagenda.ps"))))
 
 This command sets two options for the Postscript exporter, to make it
 print in two columns in landscape format—the resulting page can be cut
 in two and then used in a paper agenda.  The remaining settings modify
 the agenda prefix to omit category and scheduling information, and
 instead include a checkbox to check off items.  We also remove the tags
 to make the lines compact, and we do not want to use colors for the
 black-and-white printer.  Settings specified in
 ‘org-agenda-exporter-settings’ also apply, e.g.,
 
      (setq org-agenda-exporter-settings
            '((ps-number-of-columns 2)
              (ps-landscape-mode t)
              (org-agenda-add-entry-text-maxlines 5)
              (htmlize-output-type 'css)))
 
 but the settings in ‘org-agenda-custom-commands’ take precedence.
 
    From the command line you may also use:
 
      emacs -eval (org-batch-store-agenda-views) -kill
 
 or, if you need to modify some parameters(4)
 
      emacs -eval '(org-batch-store-agenda-views                      \
                    org-agenda-span (quote month)                     \
                    org-agenda-start-day "2007-11-01"                 \
                    org-agenda-include-diary nil                      \
                    org-agenda-files (quote ("~/org/project.org")))'  \
            -kill
 
 which creates the agenda views restricted to the file
 ‘~/org/project.org’, without diary entries and with a 30-day extent.
 
    You can also extract agenda information in a way that allows further
 processing by other programs.  See *note Extracting Agenda
 Information::, for more information.

 11.8 Using Column View in the Agenda
 ====================================
 
 Column view (see *note Column View::) is normally used to view and edit
 properties embedded in the hierarchical structure of an Org file.  It
 can be quite useful to use column view also from the agenda, where
 entries are collected by certain criteria.
 
 ‘C-c C-x C-c’ (‘org-agenda-columns’)
 
      Turn on column view in the agenda.
 
    To understand how to use this properly, it is important to realize
 that the entries in the agenda are no longer in their proper outline
 environment.  This causes the following issues:
 
   1. Org needs to make a decision which columns format to use.  Since
      the entries in the agenda are collected from different files, and
      different files may have different columns formats, this is a
      non-trivial problem.  Org first checks if
      ‘org-overriding-columns-format’ is currently set, and if so, takes
      the format from there.  You should set this variable only in the
      _local settings section_ of a custom agenda command (see *note
      Custom Agenda Views::) to make it valid for that specific agenda
      view.  If no such binding exists, it checks, in sequence,
      ‘org-columns-default-format-for-agenda’, the format associated with
      the first item in the agenda (through a property or a ‘#+COLUMNS’
      setting in that buffer) and finally ‘org-columns-default-format’.
 
   2. If any of the columns has a summary type defined (see *note Column
      attributes::), turning on column view in the agenda visits all
      relevant agenda files and make sure that the computations of this
      property are up to date.  This is also true for the special
      ‘CLOCKSUM’ property.  Org then sums the values displayed in the
      agenda.  In the daily/weekly agenda, the sums cover a single day;
      in all other views they cover the entire block.
 
      It is important to realize that the agenda may show the same entry
      _twice_—for example as scheduled and as a deadline—and it may show
      two entries from the same hierarchy (for example a _parent_ and its
      _child_).  In these cases, the summation in the agenda leads to
      incorrect results because some values count double.
 
   3. When the column view in the agenda shows the ‘CLOCKSUM’ property,
      that is always the entire clocked time for this item.  So even in
      the daily/weekly agenda, the clocksum listed in column view may
      originate from times outside the current view.  This has the
      advantage that you can compare these values with a column listing
      the planned total effort for a task—one of the major applications
      for column view in the agenda.  If you want information about
      clocked time in the displayed period use clock table mode (press
      ‘R’ in the agenda).
 
   4. When the column view in the agenda shows the ‘CLOCKSUM_T’ property,
      that is always today’s clocked time for this item.  So even in the
      weekly agenda, the clocksum listed in column view only originates
      from today.  This lets you compare the time you spent on a task for
      today, with the time already spent—via ‘CLOCKSUM’—and with the
      planned total effort for it.

 12 Markup for Rich Contents
 ***************************
 
 Org is primarily about organizing and searching through your plain-text
 notes.  However, it also provides a lightweight yet robust markup
 language for rich text formatting and more.  For instance, you may want
 to center or emphasize text.  Or you may need to insert a formula or
 image in your writing.  Org offers syntax for all of this and more.
 Used in conjunction with the export framework (see *note Exporting::),
 you can author beautiful documents in Org—like the fine manual you are
 currently reading.
 
 * Menu:
 
 * Paragraphs::                   The basic unit of text.
 * Emphasis and Monospace::       Bold, italic, etc.
 * Subscripts and Superscripts::  Simple syntax for raising/lowering text.
 * Special Symbols::              Greek letters and other symbols.
 * Embedded LaTeX::            LaTeX can be freely used inside Org documents.
 * Literal Examples::             Source code examples with special formatting.
 * Images::                       Display an image.
 * Captions::                     Describe tables, images...
 * Horizontal Rules::             Make a line.
 * Creating Footnotes::           Edit and read footnotes.
 
 
 File: org.info,  Node: Paragraphs,  Next: Emphasis and Monospace,  Up: Markup for Rich Contents
 
 12.1 Paragraphs
 ===============
 
 Paragraphs are separated by at least one empty line.  If you need to
 enforce a line break within a paragraph, use ‘\\’ at the end of a line.
 
    To preserve the line breaks, indentation and blank lines in a region,
 but otherwise use normal formatting, you can use this construct, which
 can also be used to format poetry.
 
      #+BEGIN_VERSE
       Great clouds overhead
       Tiny black birds rise and fall
       Snow covers Emacs
 
          ---AlexSchroeder
      #+END_VERSE
 
    When quoting a passage from another document, it is customary to
 format this as a paragraph that is indented on both the left and the
 right margin.  You can include quotations in Org documents like this:
 
      #+BEGIN_QUOTE
      Everything should be made as simple as possible,
      but not any simpler ---Albert Einstein
      #+END_QUOTE
 
    If you would like to center some text, do it like this:
 
      #+BEGIN_CENTER
      Everything should be made as simple as possible, \\
      but not any simpler
      #+END_CENTER
 
 
 File: org.info,  Node: Emphasis and Monospace,  Next: Subscripts and Superscripts,  Prev: Paragraphs,  Up: Markup for Rich Contents
 
 12.2 Emphasis and Monospace
 ===========================
 
 You can make words ‘*bold*’, ‘/italic/’, ‘_underlined_’, ‘=verbatim=’
 and ‘~code~’, and, if you must, ‘+strike-through+’.  Text in the code
 and verbatim string is not processed for Org specific syntax; it is
 exported verbatim.  Org provides a single command as entry point for
 inserting the marker character.
 
 ‘C-c C-x C-f’ (‘org-emphasize’)
      Prompt for a marker character and insert or change an emphasis.  If
      there is an active region, change that region to a new emphasis.
      If there is no region, just insert the marker characters and
      position the cursor between them.
 
    To turn off fontification for marked up text, you can set
 ‘org-fontify-emphasized-text’ to ‘nil’.  To narrow down the list of the
 fontified markup syntax, you can customize ‘org-emphasis-alist’(1).
 
    To hide the emphasis markup characters in your buffers, set
 ‘org-hide-emphasis-markers’ to ‘t’.
 
    Sometimes, when marked text also contains the marker character
 itself, the result may be unsettling.  For example,
 
      /One may expect this whole sentence to be italicized, but the
      following ~user/?variable~ contains =/= character, which effectively
      stops emphasis there./
 
    You can use zero width space to help Org sorting out the ambiguity.
 See *note Escape Character:: for more details.
 
    ---------- Footnotes ----------
 
    (1) The markup will still be recognized.  Just not highlighted
 visually in Emacs.
 
 
 File: org.info,  Node: Subscripts and Superscripts,  Next: Special Symbols,  Prev: Emphasis and Monospace,  Up: Markup for Rich Contents
 
 12.3 Subscripts and Superscripts
 ================================
 
 ‘^’ and ‘_’ are used to indicate super- and subscripts.  To increase the
 readability of ASCII text, it is not necessary, but OK, to surround
 multi-character sub- and superscripts with curly braces.  For example
 
      The radius of the sun is R_sun = 6.96 x 10^8 m.  On the other hand,
      the radius of Alpha Centauri is R_{Alpha Centauri} = 1.28 x R_{sun}.
 
    If you write a text where the underscore is often used in a different
 context, Org’s convention to always interpret these as subscripts can
 get in your way.  Configure the variable ‘org-use-sub-superscripts’
 and/or ‘org-export-with-sub-superscripts’ to change this convention.
 For example, when setting these variables to ‘{}’, ‘a_b’ is not
 displayed/exported(1) as a subscript, but ‘a_{b}’ is.
 
    You can set both ‘org-use-sub-superscripts’
 ‘org-export-with-sub-superscripts’ in a file using the export option
 ‘^:’ (see *note Export Settings::).  For example, ‘#+OPTIONS: ^:{}’ sets
 the two options to ‘{}’ and limits super- and subscripts to the curly
 bracket notation.
 
    You can also toggle the visual display of super- and subscripts:
 
 ‘C-c C-x \’ (‘org-toggle-pretty-entities’)
      This command formats sub- and superscripts in a WYSIWYM way.
 
    Set both ‘org-pretty-entities’ and
 ‘org-pretty-entities-include-sub-superscripts’ to ‘t’ to start with
 super- and subscripts _visually_ interpreted as specified by the option
 ‘org-use-sub-superscripts’.
 
    ---------- Footnotes ----------
 
    (1) The underlying markup still remains a sub/superscript.  Only the
 visual display and export behavior changes.
 
 
 File: org.info,  Node: Special Symbols,  Next: Embedded LaTeX,  Prev: Subscripts and Superscripts,  Up: Markup for Rich Contents
 
 12.4 Special Symbols
 ====================
 
 You can use LaTeX-like syntax to insert special symbols—named
 entities—like ‘\alpha’ to indicate the Greek letter, or ‘\to’ to
 indicate an arrow.  Completion for these symbols is available, just type
 ‘\’ and maybe a few letters, and press ‘M-<TAB>’ to see possible
 completions.  If you need such a symbol inside a word, terminate it with
 a pair of curly brackets.  For example
 
      Pro tip: Given a circle \Gamma of diameter d, the length of its
      circumference is \pi{}d.
 
    A large number of entities is provided, with names taken from both
 HTML and LaTeX; you can comfortably browse the complete list from a
 dedicated buffer using the command ‘org-entities-help’.  It is also
 possible to provide your own special symbols in the variable
 ‘org-entities-user’.
 
    During export, these symbols are transformed into the native format
 of the exporter backend.  Strings like ‘\alpha’ are exported as
 ‘&alpha;’ in the HTML output, and as ‘\(\alpha\)’ in the LaTeX output.
 Similarly, ‘\nbsp’ becomes ‘&nbsp;’ in HTML and ‘~’ in LaTeX.
 
    If you would like to see entities displayed as UTF-8 characters, use
 the following command(1):
 
 ‘C-c C-x \’ (‘org-toggle-pretty-entities’)
 
      Toggle display of entities as UTF-8 characters.  This does not
      change the buffer content which remains plain ASCII, but it
      overlays the UTF-8 character for display purposes only.
 
    In addition to regular entities defined above, Org exports in a
 special way(2) the following commonly used character combinations: ‘\-’
 is treated as a shy hyphen, ‘--’ and ‘---’ are converted into dashes,
 and ‘...’ becomes a compact set of dots.
 
    ---------- Footnotes ----------
 
    (1) You can turn this on by default by setting the variable
 ‘org-pretty-entities’, or on a per-file base with the ‘STARTUP’ option
 ‘entitiespretty’.
 
    (2) This behavior can be disabled with ‘-’ export setting (see *note
 Export Settings::).

 12.5 Embedded LaTeX
 ===================
 
 Plain ASCII is normally sufficient for almost all note taking.
 Exceptions include scientific notes, which often require mathematical
 symbols and the occasional formula.  LaTeX(1) is widely used to typeset
 scientific documents.  Org mode supports embedding LaTeX code into its
 files, because many academics are used to writing and reading LaTeX
 source code, and because it can be readily processed to produce pretty
 output for a number of export backends.

 * LaTeX fragments::           Complex formulas made easy.
 * Previewing LaTeX fragments:: What will this snippet look like?

    (1) LaTeX is a macro system based on Donald E. Knuth’s TeX system.
 Many of the features described here as “LaTeX” are really from TeX, but
 for simplicity I am blurring this distinction.
 
 
 File: org.info,  Node: LaTeX fragments,  Next: Previewing LaTeX fragments,  Up: Embedded LaTeX
 
 12.5.1 LaTeX fragments
 ----------------------
 
 Org mode can contain LaTeX math fragments, and it supports ways to
 process these for several export backends.  When exporting to LaTeX, the
 code is left as it is.  When exporting to HTML, Org can use either
 MathJax (https://www.mathjax.org) (see *note Math formatting in HTML
 export::) or transcode the math into images (see *note Previewing LaTeX
 fragments::).
 
    LaTeX fragments do not need any special marking at all.  The
 following snippets are identified as LaTeX source code:
 
    • Environments of any kind(1).  The only requirement is that the
      ‘\begin’ statement appears on a new line, preceded by only
      whitespace.
 
    • Text within the usual LaTeX math delimiters.  Prefer ‘\(...\)’ for
      inline fragments.  The ‘$...$’ alternative has some restrictions
      and may be a source of confusion.  To avoid conflicts with currency
      specifications, single ‘$’ characters are only recognized as math
      delimiters if the enclosed text contains at most two line breaks,
      is directly attached to the ‘$’ characters with no whitespace in
      between, and if the closing ‘$’ is followed by whitespace or
      punctuation (but not a dash).
 
      Sometimes, it may necessary to have a literal dollar symbol even
      when it is recognized as LaTeX math delimiter.  Org provides
      ‘\dollar’ and ‘\USD’ entities (see *note Special Symbols::) that
      are rendered as ‘$’ for such scenarios.  Also, see *note Escape
      Character::.
 
 For example:
 
      \begin{equation}                        % arbitrary environments,
      x=\sqrt{b}                              % even tables, figures, etc
      \end{equation}
 
      If $a^2=b$ and \( b=2 \), then the solution must be
      either $$ a=+\sqrt{2} $$ or \[ a=-\sqrt{2} \].
 
    LaTeX processing can be configured with the variable
 ‘org-export-with-latex’.  The default setting is ‘t’ which means MathJax
 for HTML, and no processing for ASCII and LaTeX backends.  You can also
 set this variable on a per-file basis using one of these lines:
 
 ‘#+OPTIONS: tex:t’          Do the right thing automatically (MathJax)
 ‘#+OPTIONS: tex:nil’        Do not process LaTeX fragments at all
 ‘#+OPTIONS: tex:verbatim’   Verbatim export, for jsMath or so
 
    ---------- Footnotes ----------
 
    (1) When MathJax is used, only the environments recognized by MathJax
 are processed.  When dvipng, dvisvgm, or ImageMagick suite is used to
 create images, any LaTeX environment is handled.
 
 
 File: org.info,  Node: Previewing LaTeX fragments,  Next: CDLaTeX mode,  Prev: LaTeX fragments,  Up: Embedded LaTeX
 
 12.5.2 Previewing LaTeX fragments
 ---------------------------------
 
 If you have a working LaTeX installation and ‘dvipng’, ‘dvisvgm’ or
 ‘convert’ installed(1), LaTeX fragments can be processed to produce
 images of the typeset expressions to be used for inclusion while
 exporting to HTML (see *note LaTeX fragments::), or for inline
 previewing within Org mode.
 
    You can customize the variables ‘org-format-latex-options’ and
 ‘org-format-latex-header’ to influence some aspects of the preview.  In
 particular, the ‘:scale’ (and for HTML export, ‘:html-scale’) property
 of the former can be used to adjust the size of the preview images.
 
 ‘C-c C-x C-l’ (‘org-latex-preview’)
 
      Produce a preview image of the LaTeX fragment at point and overlay
      it over the source code.  If there is no fragment at point, process
      all fragments in the current entry—between two headlines.
 
      When called with a single prefix argument, clear all images in the
      current entry.  Two prefix arguments produce a preview image for
      all fragments in the buffer, while three of them clear all the
      images in that buffer.
 
    You can turn on the previewing of all LaTeX fragments in a file with
 
      #+STARTUP: latexpreview
 
    To disable it, simply use
 
      #+STARTUP: nolatexpreview
 
    ---------- Footnotes ----------

 <https://sourceforge.net/projects/dvipng/>,
 <http://dvisvgm.bplaced.net/> and from the ImageMagick suite.  Choose
 the converter by setting the variable
 ‘org-preview-latex-default-process’ accordingly.
 
 
 File: org.info,  Node: CDLaTeX mode,  Prev: Previewing LaTeX fragments,  Up: Embedded LaTeX
 
 12.5.3 Using CDLaTeX to enter math
 ----------------------------------
 
 CDLaTeX mode is a minor mode that is normally used in combination with a
 major LaTeX mode like AUCTeX in order to speed-up insertion of
 environments and math templates.  Inside Org mode, you can make use of
 some of the features of CDLaTeX mode.  You need to install ‘cdlatex.el’
 and ‘texmathp.el’ (the latter comes also with AUCTeX) from NonGNU ELPA
 (https://elpa.nongnu.org/) with the Emacs packaging system
 (https://www.gnu.org/software/emacs/manual/html_node/emacs/Package-Installation.html)
 or alternatively from
 <https://staff.fnwi.uva.nl/c.dominik/Tools/cdlatex/>.  Do not use
 CDLaTeX mode itself under Org mode, but use the special version Org
 CDLaTeX minor mode that comes as part of Org.  Turn it on for the
 current buffer with ‘M-x org-cdlatex-mode’, or for all Org files with
 
      (add-hook 'org-mode-hook #'turn-on-org-cdlatex)
 
    When this mode is enabled, the following features are present (for
 more details see the documentation of CDLaTeX mode):
 
 ‘C-c {’
 
      Insert an environment template.
 
 ‘<TAB>’
 
      The ‘<TAB>’ key expands the template if point is inside a LaTeX
      fragment(1).  For example, ‘<TAB>’ expands ‘fr’ to ‘\frac{}{}’ and
      position point correctly inside the first brace.  Another ‘<TAB>’
      gets you into the second brace.
 
      Even outside fragments, ‘<TAB>’ expands environment abbreviations
      at the beginning of a line.  For example, if you write ‘equ’ at the
      beginning of a line and press ‘<TAB>’, this abbreviation is
      expanded to an ‘equation’ environment.  To get a list of all
      abbreviations, type ‘M-x cdlatex-command-help’.
 
 ‘^’
 ‘_’
 
      Pressing ‘_’ and ‘^’ inside a LaTeX fragment inserts these
      characters together with a pair of braces.  If you use ‘<TAB>’ to
      move out of the braces, and if the braces surround only a single
      character or macro, they are removed again (depending on the
      variable ‘cdlatex-simplify-sub-super-scripts’).
 
 ‘`’
 
      Pressing the backquote followed by a character inserts math macros,
      also outside LaTeX fragments.  If you wait more than 1.5 seconds
      after the backquote, a help window pops up.
 
 ‘'’
 
      Pressing the single-quote followed by another character modifies
      the LaTeX symbol before point with an accent or a font.  If you
      wait more than 1.5 seconds after the single-quote, a help window
      pops up.  Character modification works only inside LaTeX fragments;
      outside the quote is normal.
 
    ---------- Footnotes ----------
 
    (1) Org mode has a method to test if point is inside such a fragment,
 see the documentation of the function ‘org-inside-LaTeX-fragment-p’.

 12.6 Literal Examples

 Such examples are typeset in monospace, so this is well suited for
 source code and similar examples.

    There is one limitation, however.  You must insert a comma right
 before lines starting with either ‘*’, ‘,*’, ‘#+’ or ‘,#+’, as those may
 be interpreted as outlines nodes or some other special syntax.  Org
 transparently strips these additional commas whenever it accesses the
 contents of the block.
 
      #+BEGIN_EXAMPLE
      ,* I am no real headline
      #+END_EXAMPLE
 
    For simplicity when using small examples, you can also start the
 example lines with a colon followed by a space.  There may also be
 additional whitespace before the colon:
 
      Here is an example
         : Some example from a text file.
 
    If the example is source code from a programming language, or any
 other text that can be marked up by Font Lock in Emacs, you can ask for
 the example to look like the fontified Emacs buffer(1).  This is done
 with the code block, where you also need to specify the name of the
 major mode that should be used to fontify the example(2), see *note
 Structure Templates:: for shortcuts to easily insert code blocks.
 
      #+BEGIN_SRC emacs-lisp
        (defun org-xor (a b)
          "Exclusive or."
          (if a (not b) b))
      #+END_SRC
 
    Both in ‘example’ and in ‘src’ snippets, you can add a ‘-n’ switch to
 the ‘#+BEGIN’ line(3), to get the lines of the example numbered.  The
 ‘-n’ takes an optional numeric argument specifying the starting line
 number of the block.  If you use a ‘+n’ switch, the numbering from the
 previous numbered snippet is continued in the current one.  The ‘+n’
 switch can also take a numeric argument.  This adds the value of the
 argument to the last line of the previous block to determine the
 starting line number.
 
      #+BEGIN_SRC emacs-lisp -n 20
        ;; This exports with line number 20.
        (message "This is line 21")
      #+END_SRC
 
      #+BEGIN_SRC emacs-lisp +n 10
        ;; This is listed as line 31.
        (message "This is line 32")
      #+END_SRC
 
    In literal examples, Org interprets strings like ‘(ref:name)’ as
 labels, and use them as targets for special hyperlinks like
 ‘[[(name)]]’—i.e., the reference name enclosed in single parentheses.
 In HTML, hovering the mouse over such a link remote-highlights the
 corresponding code line(4), which is kind of cool.
 
    You can also add a ‘-r’ switch which _removes_ the labels from the
 source code(5).  With the ‘-n’ switch, links to these references are
 labeled by the line numbers from the code listing.  Otherwise links use
 the labels with no parentheses.  Here is an example:
 
      #+BEGIN_SRC emacs-lisp -n -r
        (save-excursion                 (ref:sc)
           (goto-char (point-min))      (ref:jump)
      #+END_SRC
      In line [[(sc)]] we remember the current position. [[(jump)][Line (jump)]]
      jumps to point-min.
 
    Source code and examples may be _indented_ in order to align nicely
 with the surrounding text, and in particular with plain list structure
 (see *note Plain Lists::).  By default, Org only retains the relative
 indentation between lines, e.g., when exporting the contents of the
 block.  However, you can use the ‘-i’ switch to also preserve the global
 indentation, if it does matter.  See *note Editing Source Code::.
 
    If the syntax for the label format conflicts with the language
 syntax, use a ‘-l’ switch to change the format, for example
 
      #+BEGIN_SRC pascal -n -r -l "((%s))"
 
 See also the variable ‘org-coderef-label-format’.
 
    HTML export also allows examples to be published as text areas (see
 *note Text areas in HTML export::).
 
    Because the ‘#+BEGIN’ ... ‘#+END’ patterns need to be added so often,
 a shortcut is provided (see *note Structure Templates::).
 
 ‘C-c '’ (‘org-edit-special’)
      Edit the source code example at point in its native mode.  This
      works by switching to a temporary buffer with the source code.  You
      need to exit by pressing ‘C-c '’ again.  The edited version then
      replaces the old version in the Org buffer.  Fixed-width
      regions—where each line starts with a colon followed by a space—are
      edited using Artist mode(6) to allow creating ASCII drawings
      easily.  Using this command in an empty line creates a new
      fixed-width region.
 
    Calling ‘org-store-link’ (see *note Handling Links::) while editing a
 source code example in a temporary buffer created with ‘C-c '’ prompts
 for a label.  Make sure that it is unique in the current buffer, and
 insert it with the proper formatting like ‘(ref:label)’ at the end of
 the current line.  Then the label is stored as a link ‘(label)’, for
 retrieval with ‘C-c C-l’.

 version 1.34 of the ‘htmlize.el’ package, which you need to install).
 Fontified code chunks in LaTeX can be achieved using either the listings

 12.7 Images
 ===========
 
 An image is a link to an image file(1) that does not have a description
 part, for example
 
      ./img/cat.jpg
 
    If you wish to define a caption for the image (see *note Captions::)
 and maybe a label for internal cross-references (see *note Internal
 Links::), make sure that the link is on a line by itself and precede it
 with ‘CAPTION’ and ‘NAME’ keywords as follows:
 
      #+CAPTION: This is the caption for the next figure link (or table)
      #+NAME:   fig:SED-HR4049
      [[./img/a.jpg]]
 
    Such images can be displayed within the buffer with the following
 command:
 
 ‘C-c C-x C-v’ (‘org-toggle-inline-images’)
      Toggle the inline display of linked images.  When called with a
      prefix argument, also display images that do have a link
      description.  You can ask for inline images to be displayed at
      startup by configuring the variable
      ‘org-startup-with-inline-images’(2).
 
    By default, Org mode displays inline images according to their actual
 width, but no wider than ‘fill-column’ characters.
 
    You can customize the displayed image width using
 ‘org-image-actual-width’ variable (globally) or ‘ORG-IMAGE-ACTUAL-WIDTH’
 property (subtree-level)(3).  Their value can be the following:
    • (default) Non-‘nil’, use the actual width of images when inlining
      them.  If the actual width is too wide, limit it according to
      ‘org-image-max-width’.
    • When set to a number, use imagemagick (when available) to set the
      image’s width to this value.
    • When set to a number in a list, try to get the width from any
      ‘#+ATTR.*’ keyword if it matches a width specification like:
           #+ATTR_HTML: :width 300px
      and fall back on that number if none is found.
    • When set to ‘nil’, try to get the width from an ‘#+ATTR.*’ keyword
      and fall back on the original width or ‘org-image-max-width’ if
      none is found.
 
    ‘org-image-max-width’ limits the maximum displayed image width, but
 only when the image width is not set explicitly.  Possible maximum width
 can be set to:
    • (default) ‘fill-column’, limit width to ‘fill-column’ number of
      characters.
    • ‘window’, limit width to current window width.
    • integer number, limit width to that specified number of pixels.
    • ‘nil’, do not limit the width.
 
    Org mode can left-align, center or right-align the display of inline
 images.  This setting is controlled (globally) by ‘org-image-align’.
 Only standalone images are affected, corresponding to links with no
 surrounding text in their paragraph except for whitespace.  Its value
 can be the following:
    • (default) The symbol ‘left’, which inserts the image where the link
      appears in the buffer.
    • The symbol ‘center’, which will preview links centered in the Emacs
      window.
    • The symbol ‘right’, which will preview links right-aligned in the
      Emacs window.
 
    Inline image alignment can be specified for each link using the
 ‘#+ATTR.*’ keyword if it matches an alignment specification like:
      #+ATTR_HTML: :align center
    Org will use the alignment specification from any ‘#+ATTR.*’ keyword,
 such as ‘#+ATTR_HTML’ or ‘#+ATTR_LATEX’, but ‘#+ATTR_ORG’ (if present)
 will override the others.  For instance, this link
      #+ATTR_HTML: :align right
      #+ATTR_ORG: :align center
      [[/path/to/image/file.png]]
    will be displayed centered in Emacs but exported right-aligned to
 HTML.
 
    When ‘#+ATTR_ORG’ is not set, inline image alignment is also read
 from the ‘:center’ attribute supported by some export backends (like
 HTML, LaTeX and Beamer.)
 
    Inline images can also be displayed when cycling the folding state.
 When custom option ‘org-cycle-inline-images-display’ is set, the visible
 inline images under subtree will be displayed automatically.
 
    ---------- Footnotes ----------
 
    (1) What Emacs considers to be an image depends on
 ‘image-file-name-extensions’ and ‘image-file-name-regexps’.
 
    (2) The variable ‘org-startup-with-inline-images’ can be set within a
 buffer with the ‘STARTUP’ options ‘inlineimages’ and ‘noinlineimages’.
 
    (3) The width can be customized in Emacs >= 24.1, built with
 imagemagick support.

 12.8 Captions
 =============
 
 You can assign a caption to a specific part of a document by inserting a
 ‘CAPTION’ keyword immediately before it:
 
      #+CAPTION: This is the caption for the next table (or link)
      | ... | ... |
      |-----+-----|
 
    Optionally, the caption can take the form:
 
      #+CAPTION[Short caption]: Longer caption.
 
    Even though images and tables are prominent examples of captioned
 structures, the same caption mechanism can apply to many others—e.g.,
 LaTeX equations, source code blocks.  Depending on the export backend,
 those may or may not be handled.

 12.9 Horizontal Rules
 =====================
 
 A line consisting of only dashes, and at least 5 of them, is exported as
 a horizontal line.
 
 
 File: org.info,  Node: Creating Footnotes,  Prev: Horizontal Rules,  Up: Markup for Rich Contents
 
 12.10 Creating Footnotes
 ========================
 
 A footnote is started by a footnote marker in square brackets in column
 0, no indentation allowed.  It ends at the next footnote definition,
 headline, or after two consecutive empty lines.  The footnote reference
 is simply the marker in square brackets, inside text.  Markers always
 start with ‘fn:’.  For example:
 
      The Org website[fn:1] now looks a lot better than it used to.
      ...
      [fn:50] The link is: https://orgmode.org
 
    Org mode extends the number-based syntax to _named_ footnotes and
 optional inline definition.  Here are the valid references:
 
 ‘[fn:NAME]’
      A named footnote reference, where NAME is a unique label word, or,
      for simplicity of automatic creation, a number.
 
 ‘[fn:: This is the inline definition of this footnote]’
      An anonymous footnote where the definition is given directly at the
      reference point.
 
 ‘[fn:NAME: a definition]’
      An inline definition of a footnote, which also specifies a name for
      the note.  Since Org allows multiple references to the same note,
      you can then use ‘[fn:NAME]’ to create additional references.
 
    Footnote labels can be created automatically, or you can create names
 yourself.  This is handled by the variable ‘org-footnote-auto-label’ and
 its corresponding ‘STARTUP’ keywords.  See the docstring of that
 variable for details.
 
    The following command handles footnotes:
 
 ‘C-c C-x f’
      The footnote action command.
 
      When point is on a footnote reference, jump to the definition.
      When it is at a definition, jump to the—first—reference.
 
      Otherwise, create a new footnote.  Depending on the variable
      ‘org-footnote-define-inline’(1), the definition is placed right
      into the text as part of the reference, or separately into the
      location determined by the variable ‘org-footnote-section’.
 
      When this command is called with a prefix argument, a menu of
      additional options is offered:
 
      ‘s’     Sort the footnote definitions by reference sequence.
      ‘r’     Renumber the simple ‘fn:N’ footnotes.
      ‘S’     Short for first ‘r’, then ‘s’ action.
      ‘n’     Rename all footnotes into a ‘fn:1’ ... ‘fn:n’ sequence.
      ‘d’     Delete the footnote at point, including definition and
              references.
 
      Depending on the variable ‘org-footnote-auto-adjust’(2),
      renumbering and sorting footnotes can be automatic after each
      insertion or deletion.
 
 ‘C-c C-c’
      If point is on a footnote reference, jump to the definition.  If it
      is at the definition, jump back to the reference.  When called at a
      footnote location with a prefix argument, offer the same menu as
      ‘C-c C-x f’.
 
 ‘C-c C-o’ or ‘mouse-1/2’
      Footnote labels are also links to the corresponding definition or
      reference, and you can use the usual commands to follow these
      links.
 
    ---------- Footnotes ----------
 
    (1) The corresponding in-buffer setting is: ‘#+STARTUP: fninline’ or
 ‘#+STARTUP: nofninline’.
 
    (2) The corresponding in-buffer options are ‘#+STARTUP: fnadjust’ and
 ‘#+STARTUP: nofnadjust’.

 13 Exporting
 ************
 
 At some point you might want to print your notes, publish them on the
 web, or share them with people not using Org.  Org can convert and
 export documents to a variety of other formats while retaining as much
 structure (see *note Document Structure::) and markup (see *note Markup
 for Rich Contents::) as possible.
 
    The libraries responsible for translating Org files to other formats
 are called _backends_.  Org ships with support for the following
 backends:
 
    • _ascii_ (ASCII format)
    • _beamer_ (LaTeX Beamer format)
    • _html_ (HTML format)
    • _icalendar_ (iCalendar format)
    • _latex_ (LaTeX format)
    • _md_ (Markdown format)
    • _odt_ (OpenDocument Text format)
    • _org_ (Org format)
    • _texinfo_ (Texinfo format)
    • _man_ (Man page format)
 
    Users can install libraries for additional formats from the Emacs
 packaging system.  For easy discovery, these packages have a common
 naming scheme: ‘ox-NAME’, where NAME is a format.  For example,
 ‘ox-koma-letter’ for _koma-letter_ backend.  More libraries can be found
 in the ‘org-contrib’ repository (see *note Installation::).
 
    Org only loads backends for the following formats by default: ASCII,
 HTML, iCalendar, LaTeX, and ODT.  Additional backends can be loaded in
 either of two ways: by configuring the ‘org-export-backends’ variable,
 or by requiring libraries in the Emacs init file.  For example, to load
 the Markdown backend, add this to your Emacs config:
 
      (require 'ox-md)

 File: org.info,  Node: The Export Dispatcher,  Next: Export Settings,  Up: Exporting
 
 13.1 The Export Dispatcher
 ==========================
 
 The export dispatcher is the main interface for Org’s exports.  A
 hierarchical menu presents the currently configured export formats.
 Options are shown as easy toggle switches on the same screen.
 
    Org also has a minimal prompt interface for the export dispatcher.
 When the variable ‘org-export-dispatch-use-expert-ui’ is set to a
 non-‘nil’ value, Org prompts in the minibuffer.  To switch back to the
 hierarchical menu, press ‘?’.
 
 ‘C-c C-e’ (‘org-export-dispatch’)
 
      Invokes the export dispatcher interface.  The options show default
      settings.  The ‘C-u’ prefix argument preserves options from the
      previous export, including any subtree selections.
 
    Org exports the entire buffer by default.  If the Org buffer has an
 active region, then Org exports just that region.
 
    Within the dispatcher interface, the following key combinations can
 further alter what is exported, and how.
 
 ‘C-a’
 
      Toggle asynchronous export.  Asynchronous export uses an external
      Emacs process with a specially configured initialization file to
      complete the exporting process in the background, without tying-up
      Emacs.  This is particularly useful when exporting long documents.
 
      Output from an asynchronous export is saved on the _export stack_.
      To view this stack, call the export dispatcher with a double ‘C-u’
      prefix argument.  If already in the export dispatcher menu, ‘&’
      displays the stack.
 
      You can make asynchronous export the default by setting
      ‘org-export-in-background’.
 
      You can set the initialization file used by the background process
      by setting ‘org-export-async-init-file’.
 
 ‘C-b’
 
      Toggle body-only export.  Useful for excluding headers and footers
      in the export.  Affects only those backend formats that have
      sections like ‘<head>...</head>’ in HTML.
 
      To make body-only export the default, customize the variable
      ‘org-export-body-only’.
 
 ‘C-f’
 
      Toggle force-publishing export.  Publish functions normally only
      publish changed files (see [BROKEN LINK: **Triggering
      Publication]).  Forced publishing causes files to be published even
      if their timestamps do not indicate the file has been changed.
 
      To make forced publishing the default, customize the variable
      ‘org-export-force-publishing’.  (This is similar to
      ‘org-publish-use-timestamps-flag’, but only affects the export
      dispatcher.)
 
 ‘C-s’
 
      Toggle subtree export.  When turned on, Org exports only the
      subtree starting from point position at the time the export
      dispatcher was invoked.  Org uses the top heading of this subtree
      as the document’s title.  If point is not on a heading, Org uses
      the nearest enclosing header.  If point is in the document
      preamble, Org signals an error and aborts export.
 
      To make subtree export the default, customize the variable
      ‘org-export-initial-scope’.
 
 ‘C-v’
 
      Toggle visible-only export.  This is useful for exporting only
      certain parts of an Org document by adjusting the visibility of
      particular headings.  See also *note Sparse Trees::.
 
      To make visible-only export the default, customize the variable
      ‘org-export-visible-only’.

 13.2 Export Settings
 ====================
 
 Export options can be set: globally with variables; for an individual
 file by making variables buffer-local with in-buffer settings (see *note
 In-buffer Settings::); by setting individual keywords or specifying them
 in compact form with the ‘OPTIONS’ keyword; or for a tree by setting
 properties (see *note Properties and Columns::).  Options set at a
 specific level override options set at a more general level.
 
    In-buffer settings may appear anywhere in the file, either directly
 or indirectly through a file included using ‘#+SETUPFILE: filename or
 URL’ syntax.  Option keyword sets tailored to a particular backend can
 be inserted from the export dispatcher (see *note The Export
 Dispatcher::) using the ‘Insert template’ command by pressing ‘#’.  To
 insert keywords individually, a good way to make sure the keyword is
 correct is to type ‘#+’ and then to use ‘M-<TAB>’(1) for completion.
 
    The export keywords available for every backend, and their equivalent
 global variables, include:
 
 ‘AUTHOR’
      The document author (‘user-full-name’).
 
 ‘CREATOR’
      Entity responsible for output generation
      (‘org-export-creator-string’).
 
 ‘DATE’
      A date or a timestamp(2).
 
 ‘EMAIL’
      The email address (‘user-mail-address’).
 
 ‘LANGUAGE’
      Language to use for translating certain strings
      (‘org-export-default-language’).  With ‘#+LANGUAGE: fr’, for
      example, Org translates ‘Table of contents’ to the French ‘Table
      des matières’(3).
 
 ‘SELECT_TAGS’
      List of tags that will, if present, be selected for export.  The
      default value is ‘org-export-select-tags’ ‘("export")’.  When a
      tree is tagged with ‘export’, Org selects that tree and its
      subtrees for export, ignoring all the other sections that do not
      possess the ‘export’ tag.
 
      When selectively exporting files with ‘export’ tags set, Org does
      not export any text that appears before the first headline.
 
      Note that a file without the ‘export’ tags will export all its
      sections.
 
      To select non-default tags for export, customize
      ‘org-export-select-tags’ (globally) or add ‘#+SELECT_TAGS: tag1
      tag2’ to the document.
 
 ‘EXCLUDE_TAGS’
      List of tags that will be excluded from export.  The default value
      is ‘org-export-exclude-tags’ ‘("noexport")’.  When a tree is tagged
      with ‘noexport’, Org excludes that tree and its subtrees from
      export.
 
      Entries tagged with ‘noexport’ are unconditionally excluded from
      the export, even if they have an ‘export’ tag.  Even if a subtree
      is not exported, Org executes any code blocks contained there.
 
      To select non-default tags for the exclusion, customize
      ‘org-export-exclude-tags’ (globally) or add ‘#+EXCLUDE_TAGS: tag1
      tag2’ to the document.
 
 ‘TITLE’
      Org displays this title.  For long titles, use multiple ‘#+TITLE’
      lines.
 
 ‘EXPORT_FILE_NAME’
      The name of the output file to be generated.  Otherwise, Org
      generates the file name based on the buffer name and the extension
      based on the backend format.
 
    The ‘OPTIONS’ keyword is a compact form.  To configure multiple
 options, use several ‘OPTIONS’ lines.  ‘OPTIONS’ recognizes the
 following arguments.
 
 ‘'’
      Toggle smart quotes (‘org-export-with-smart-quotes’).  Depending on
      the language used, when activated, Org treats pairs of double
      quotes as primary quotes, pairs of single quotes as secondary
      quotes, and single quote marks as apostrophes.
 
 ‘*’
      Toggle emphasized text (‘org-export-with-emphasize’).
 
 ‘-’
      Toggle conversion of special strings
      (‘org-export-with-special-strings’).
 
 ‘:’
      Toggle fixed-width sections (‘org-export-with-fixed-width’).
 
 ‘<’
      Toggle inclusion of time/date active/inactive stamps
      (‘org-export-with-timestamps’).
 
 ‘\n’
      Toggles whether to preserve line breaks
      (‘org-export-preserve-breaks’).
 
 ‘^’
      Toggle TeX-like syntax for sub- and superscripts.  If you write
      ‘^:{}’, ‘a_{b}’ is interpreted, but the simple ‘a_b’ is left as it
      is (‘org-export-with-sub-superscripts’).
 
 ‘arch’
      Configure how archived trees are exported.  When set to ‘headline’,
      the export process skips the contents and processes only the
      headlines (‘org-export-with-archived-trees’).
 
 ‘author’
      Toggle inclusion of author name into exported file
      (‘org-export-with-author’).
 
 ‘expand-links’
      Toggle expansion of environment variables in file paths
      (‘org-export-expand-links’).
 
 ‘broken-links’
      Toggles if Org should continue exporting upon finding a broken
      internal link.  When set to ‘mark’, Org clearly marks the problem
      link in the output (‘org-export-with-broken-links’).
 
 ‘c’
      Toggle inclusion of ‘CLOCK’ keywords (‘org-export-with-clocks’).
 
 ‘creator’
      Toggle inclusion of creator information in the exported file
      (‘org-export-with-creator’).
 
 ‘d’
      Toggles inclusion of drawers, or list of drawers to include, or
      list of drawers to exclude (‘org-export-with-drawers’).
 
 ‘date’
      Toggle inclusion of a date into exported file
      (‘org-export-with-date’).
 
 ‘e’
      Toggle inclusion of entities (‘org-export-with-entities’).
 
 ‘email’
      Toggle inclusion of the author’s e-mail into exported file
      (‘org-export-with-email’).
 
 ‘f’
      Toggle the inclusion of footnotes (‘org-export-with-footnotes’).
 
 ‘H’
      Set the number of headline levels for export
      (‘org-export-headline-levels’).  Below that level, headlines are
      treated differently.  In most backends, they become list items.
 
 ‘inline’
      Toggle inclusion of inlinetasks (‘org-export-with-inlinetasks’).
 
 ‘num’
      Toggle section-numbers (‘org-export-with-section-numbers’).  When
      set to number N, Org numbers only those headlines at level N or
      above.  Set ‘UNNUMBERED’ property to non-‘nil’ to disable numbering
      of heading and subheadings entirely.  Moreover, when the value is
      ‘notoc’ the headline, and all its children, do not appear in the
      table of contents either (see *note Table of Contents::).
 
 ‘p’
      Toggle export of planning information (‘org-export-with-planning’).
      “Planning information” comes from lines located right after the
      headline and contain any combination of these cookies: ‘SCHEDULED’,
      ‘DEADLINE’, or ‘CLOSED’.
 
 ‘pri’
      Toggle inclusion of priority cookies (‘org-export-with-priority’).
 
 ‘prop’
      Toggle inclusion of property drawers, or list the properties to
      include (‘org-export-with-properties’).
 
 ‘stat’
      Toggle inclusion of statistics cookies
      (‘org-export-with-statistics-cookies’).
 
 ‘tags’
      Toggle inclusion of tags, may also be ‘not-in-toc’
      (‘org-export-with-tags’).
 
 ‘tasks’
      Toggle inclusion of tasks (TODO items); or ‘nil’ to remove all
      tasks; or ‘todo’ to remove done tasks; or list the keywords to keep
      (‘org-export-with-tasks’).
 
 ‘tex’
      ‘nil’ does not export; ‘t’ exports; ‘verbatim’ keeps everything in
      verbatim (‘org-export-with-latex’).
 
 ‘timestamp’
      Toggle inclusion of the creation time in the exported file
      (‘org-export-timestamp-file’).
 
 ‘title’
      Toggle inclusion of title (‘org-export-with-title’).
 
 ‘toc’
      Toggle inclusion of the table of contents, or set the level limit
      (‘org-export-with-toc’).
 
 ‘todo’
      Toggle inclusion of TODO keywords into exported text
      (‘org-export-with-todo-keywords’).
 
 ‘|’
      Toggle inclusion of tables (‘org-export-with-tables’).
 
    When exporting subtrees, special node properties can override the
 above keywords.  These properties have an ‘EXPORT_’ prefix.  For
 example, ‘DATE’ becomes, ‘EXPORT_DATE’ when used for a specific subtree.
 Except for ‘SETUPFILE’, all other keywords listed above have an
 ‘EXPORT_’ equivalent.
 
    If ‘org-export-allow-bind-keywords’ is non-‘nil’, Emacs variables can
 become buffer-local during export by using the ‘BIND’ keyword.  Its
 syntax is ‘#+BIND: variable value’.  This is particularly useful for
 in-buffer settings that cannot be changed using keywords.
 
    ---------- Footnotes ----------
 
    (1) Many desktops intercept ‘M-<TAB>’ to switch windows.  Use ‘C-M-i’
 or ‘<ESC> <TAB>’ instead.
 
    (2) The variable ‘org-export-date-timestamp-format’ defines how this

 configuration.  See *note LaTeX specific export settings::.
 
 
 File: org.info,  Node: Table of Contents,  Next: Include Files,  Prev: Export Settings,  Up: Exporting
 
 13.3 Table of Contents
 ======================
 
 The table of contents includes all headlines in the document.  Its depth
 is therefore the same as the headline levels in the file.  If you need
 to use a different depth, or turn it off entirely, set the
 ‘org-export-with-toc’ variable accordingly.  You can achieve the same on
 a per file basis, using the following ‘toc’ item in ‘OPTIONS’ keyword:
 
      #+OPTIONS: toc:2          (only include two levels in TOC)
      #+OPTIONS: toc:nil        (no default TOC at all)
 
    Org includes both numbered and unnumbered headlines in the table of
 contents(1).  If you need to exclude an unnumbered headline, along with
 all its children, set the ‘UNNUMBERED’ property to ‘notoc’ value.
 
      * Subtree not numbered, not in table of contents either
        :PROPERTIES:
        :UNNUMBERED: notoc
        :END:
 
    Org normally inserts the table of contents in front of the exported
 document.  To move the table of contents to a different location, first
 turn off the default with ‘org-export-with-toc’ variable or with
 ‘#+OPTIONS: toc:nil’.  Then insert ‘#+TOC: headlines N’ at the desired
 location(s).
 
      #+OPTIONS: toc:nil
      ...
      #+TOC: headlines 2
 
    To adjust the table of contents depth for a specific section of the
 Org document, append an additional ‘local’ parameter.  This parameter
 becomes a relative depth for the current level.  The following example
 inserts a local table of contents, with direct children only.
 
      * Section
      #+TOC: headlines 1 local
 
    Note that for this feature to work properly in LaTeX export, the Org
 file requires the inclusion of the titletoc package.  Because of
 compatibility issues, titletoc has to be loaded _before_ hyperref.
 Customize the ‘org-latex-default-packages-alist’ variable.
 
    The following example inserts a table of contents that links to the
 children of the specified target.
 
      * Target
        :PROPERTIES:
        :CUSTOM_ID: TargetSection
        :END:
      ** Heading A
      ** Heading B
      * Another section
      #+TOC: headlines 1 :target #TargetSection
 
    The ‘:target’ attribute is supported in HTML, Markdown, ODT, and
 ASCII export.
 
    Use the ‘TOC’ keyword to generate list of tables—respectively, all
 listings—with captions.
 
      #+TOC: listings
      #+TOC: tables
 
    Normally Org uses the headline for its entry in the table of
 contents.  But with ‘ALT_TITLE’ property, a different entry can be
 specified for the table of contents.
 
    ---------- Footnotes ----------
 
    (1) At the moment, some export backends do not obey this
 specification.  For example, LaTeX export excludes every unnumbered
 headline from the table of contents.
 
 
 File: org.info,  Node: Include Files,  Next: Macro Replacement,  Prev: Table of Contents,  Up: Exporting
 
 13.4 Include Files
 ==================
 
 *note During export: Summary of the export process, you can include the
 content of another file.  For example, to include your ‘.emacs’ file,
 you could use:
 
      #+INCLUDE: "~/.emacs" src emacs-lisp
 
 There are three positional arguments after the include keyword, they
 are:
   1. The file name, this is the sole mandatory argument.  Org neither
      checks for correctness or validates the content in any way.
   2. The block name to wrap the file content in.  When this is
      ‘example’, ‘export’, or ‘src’ the content is escaped by
      ‘org-escape-code-in-string’.  Arbitrary block names may be given,
      however block names starting with ‘:’ must be quoted, i.e.
      ‘":name"’.
   3. The source code language to use for formatting the contents.  This
      is relevant to both ‘export’ and ‘src’ block types.
 
    If an included file is not specified as having any markup language,
 Org assumes it be in Org format and proceeds as usual with a few
 exceptions.  Org makes the footnote labels (see *note Creating
 Footnotes::) in the included file local to that file.  The contents of
 the included file belong to the same structure—headline, item—containing
 the ‘INCLUDE’ keyword.  In particular, headlines within the file become
 children of the current section.  That behavior can be changed by
 providing an additional keyword parameter, ‘:minlevel’.  It shifts the
 headlines in the included file to become the lowest level.  For example,
 this syntax makes the included file a sibling of the current top-level
 headline:
 
      #+INCLUDE: "~/my-book/chapter2.org" :minlevel 1
 
    Inclusion of only portions of files are specified using ranges
 parameter with ‘:lines’ keyword.  The line at the upper end of the range
 will not be included.  The start and/or the end of the range may be
 omitted to use the obvious defaults.
 
 ‘#+INCLUDE: "~/.emacs" :lines "5-10"’   Include lines 5 to 10, 10 excluded
 ‘#+INCLUDE: "~/.emacs" :lines "-10"’    Include lines 1 to 10, 10 excluded
 ‘#+INCLUDE: "~/.emacs" :lines "10-"’    Include lines from 10 to EOF
 
    Inclusions may specify a file-link to extract an object matched by
 ‘org-link-search’(1) (see *note Search Options::).  The ranges for
 ‘:lines’ keyword are relative to the requested element.  Therefore,
 
      #+INCLUDE: "./paper.org::*conclusion" :lines "1-20"
 
 includes the first 20 lines of the headline named ‘conclusion’.
 
    To extract only the contents of the matched object, set
 ‘:only-contents’ property to non-‘nil’.  This omits any planning lines
 or property drawers.  For example, to include the body of the heading
 with the custom ID ‘theory’, you can use
 
      #+INCLUDE: "./paper.org::#theory" :only-contents t
 
    The following command allows navigating to the included document:
 
 ‘C-c '’ (‘org-edit-special’)
 
      Visit the included file at point.
 
    ---------- Footnotes ----------
 
    (1) Note that ‘org-link-search-must-match-exact-headline’ is locally
 bound to non-‘nil’.  Therefore, ‘org-link-search’ only matches headlines
 and named elements.
 
 
 File: org.info,  Node: Macro Replacement,  Next: Comment Lines,  Prev: Include Files,  Up: Exporting
 
 13.5 Macro Replacement
 ======================
 
 Macros replace text snippets during export.  Macros are defined globally
 in ‘org-export-global-macros’, or document-wise with the following
 syntax:
 
      #+MACRO: name   replacement text; $1, $2 are arguments
 
 which can be referenced using ‘{{{name(arg1, arg2)}}}’(1).  For example
 
      #+MACRO: poem Rose is $1, violet's $2. Life's ordered: Org assists you.
      {{{poem(red,blue)}}}
 
 becomes
 
      Rose is red, violet's blue.  Life's ordered: Org assists you.
 
    As a special case, Org parses any replacement text starting with
 ‘(eval’ as an Emacs Lisp expression and evaluates it accordingly.
 Within such templates, arguments become strings.  Thus, the following
 macro
 
      #+MACRO: gnustamp (eval (concat "GNU/" (capitalize $1)))
 
 turns ‘{{{gnustamp(linux)}}}’ into ‘GNU/Linux’ during export.
 
    Org recognizes macro references in following Org markup areas:
 paragraphs, headlines, verse blocks, tables cells and lists.  Org also
 recognizes macro references in keywords, such as ‘CAPTION’, ‘TITLE’,
 ‘AUTHOR’, ‘DATE’, and for some backend specific export options.
 
    Org comes with following pre-defined macros:
 
 ‘{{{keyword(NAME)}}}’
 ‘{{{title}}}’
 ‘{{{author}}}’
 ‘{{{email}}}’
      The ‘keyword’ macro collects all values from NAME keywords
      throughout the buffer, separated with white space.  ‘title’,
      ‘author’ and ‘email’ macros are shortcuts for, respectively,
      ‘{{{keyword(TITLE)}}}’, ‘{{{keyword(AUTHOR)}}}’ and
      ‘{{{keyword(EMAIL)}}}’.
 
 ‘{{{date}}}’
 ‘{{{date(FORMAT)}}}’
      This macro refers to the ‘DATE’ keyword.  FORMAT is an optional
      argument to the ‘date’ macro that is used only if ‘DATE’ is a
      single timestamp.  FORMAT should be a format string understood by
      ‘format-time-string’.
 
 ‘{{{time(FORMAT)}}}’
 ‘{{{modification-time(FORMAT, VC)}}}’
      These macros refer to the document’s date and time of export and
      date and time of modification.  FORMAT is a string understood by
      ‘format-time-string’.  If the second argument to the
      ‘modification-time’ macro is non-‘nil’, Org uses ‘vc.el’ to
      retrieve the document’s modification time from the version control
      system.  Otherwise Org reads the file attributes.
 
 ‘{{{input-file}}}’
      This macro refers to the filename of the exported file.
 
 ‘{{{property(PROPERTY-NAME)}}}’
 ‘{{{property(PROPERTY-NAME, SEARCH OPTION)}}}’
      This macro returns the value of property PROPERTY-NAME in the
      current entry.  If SEARCH-OPTION (see *note Search Options::)
      refers to a remote entry, use it instead.
 
 ‘{{{n}}}’
 ‘{{{n(NAME)}}}’
 ‘{{{n(NAME, ACTION)}}}’
      This macro implements custom counters by returning the number of
      times the macro has been expanded so far while exporting the
      buffer.  You can create more than one counter using different NAME
      values.  If ACTION is ‘-’, previous value of the counter is held,
      i.e., the specified counter is not incremented.  If the value is a
      number, the specified counter is set to that value.  If it is any
      other non-empty string, the specified counter is reset to 1.  You
      may leave NAME empty to reset the default counter.
 
    Moreover, inline source blocks (see *note Structure of Code Blocks::)
 use the special ‘results’ macro to mark their output.  As such, you are
 advised against re-defining it, unless you know what you are doing.
 
    The surrounding brackets can be made invisible by setting
 ‘org-hide-macro-markers’ to a non-‘nil’ value.
 
    Org expands macros at the very beginning of the export process.
 
    ---------- Footnotes ----------
 
    (1) Since commas separate the arguments, commas within arguments have
 to be escaped with the backslash character.  So only those backslash
 characters before a comma need escaping with another backslash
 character.

 13.6 Comment Lines
 ==================
 
 Lines starting with zero or more whitespace characters followed by one
 ‘#’ and a whitespace are treated as comments and, as such, are not
 exported.
 
    Likewise, regions surrounded by ‘#+BEGIN_COMMENT’ ... ‘#+END_COMMENT’
 are not exported.
 
    Finally, a ‘COMMENT’ keyword at the beginning of an entry, but after
 any other keyword or priority cookie, comments out the entire subtree.
 In this case, the subtree is not exported and no code block within it is
 executed either(1).  The command below helps changing the comment status
 of a headline.
 
 ‘C-c ;’ (‘org-toggle-comment’)
 
      Toggle the ‘COMMENT’ keyword at the beginning of an entry.
 
    ---------- Footnotes ----------
 
    (1) For a less drastic behavior, consider using a select tag (see
 *note Export Settings::) instead.

 13.7 ASCII/Latin-1/UTF-8 export
 ===============================
 
 ASCII export produces an output file containing only plain ASCII
 characters.  This is the simplest and most direct text output.  It does
 not contain any Org markup.  Latin-1 and UTF-8 export use additional
 characters and symbols available in these encoding standards.  All three
 of these export formats offer the most basic of text output for maximum
 portability.
 
    On export, Org fills and justifies text according to the text width
 set in ‘org-ascii-text-width’.
 
    Org exports links using a footnote-like style where the descriptive
 part is in the text and the link is in a note before the next heading.
 See the variable ‘org-ascii-links-to-notes’ for details.
 
 ASCII export commands
 ---------------------
 
 ‘C-c C-e t a’ (‘org-ascii-export-to-ascii’)
 ‘C-c C-e t l’
 ‘C-c C-e t u’
 
      Export as an ASCII file with a ‘.txt’ extension.  For ‘myfile.org’,
      Org exports to ‘myfile.txt’, overwriting without warning.  For
      ‘myfile.txt’, Org exports to ‘myfile.txt.txt’ in order to prevent
      data loss.
 
 ‘C-c C-e t A’ (‘org-ascii-export-to-ascii’)
 ‘C-c C-e t L’
 ‘C-c C-e t U’
 
      Export to a temporary buffer.  Does not create a file.
 
 ASCII specific export settings
 ------------------------------
 
 The ASCII export backend has one extra keyword for customizing ASCII
 output.  Setting this keyword works similar to the general options (see
 *note Export Settings::).
 
 ‘SUBTITLE’
      The document subtitle.  For long subtitles, use multiple
      ‘#+SUBTITLE’ lines in the Org file.  Org prints them on one
      continuous line, wrapping into multiple lines if necessary.
 
 Header and sectioning structure
 -------------------------------
 
 Org converts the first three outline levels into headlines for ASCII
 export.  The remaining levels are turned into lists.  To change this
 cut-off point where levels become lists, see *note Export Settings::.
 
 Quoting ASCII text
 ------------------
 
 To insert text within the Org file by the ASCII backend, use one the
 following constructs, inline, keyword, or export block:
 
      Inline text @@ascii:and additional text@@ within a paragraph.
 
      #+ASCII: Some text
 
      #+BEGIN_EXPORT ascii
      Org exports text in this block only when using ASCII backend.
      #+END_EXPORT
 
 ASCII specific attributes
 -------------------------
 
 ASCII backend recognizes only one attribute, ‘:width’, which specifies
 the width of a horizontal rule in number of characters.  The keyword and
 syntax for specifying widths is:
 
      #+ATTR_ASCII: :width 10
      -----
 
 ASCII special blocks
 --------------------
 
 Besides ‘#+BEGIN_CENTER’ blocks (see *note Paragraphs::), ASCII backend
 has these two left and right justification blocks:
 
      #+BEGIN_JUSTIFYLEFT
      It's just a jump to the left...
      #+END_JUSTIFYLEFT
 
      #+BEGIN_JUSTIFYRIGHT
      ...and then a step to the right.
      #+END_JUSTIFYRIGHT

 13.8.2 Beamer specific export settings
 --------------------------------------
 
 Beamer export backend has several additional keywords for customizing
 Beamer output.  These keywords work similar to the general options
 settings (see *note Export Settings::).
 
 ‘BEAMER_THEME’
      The Beamer layout theme (‘org-beamer-theme’).  Use square brackets
      for options.  For example:
 
           #+BEAMER_THEME: Rochester [height=20pt]
 
 ‘BEAMER_FONT_THEME’
      The Beamer font theme.
 
 ‘BEAMER_INNER_THEME’
      The Beamer inner theme.
 
 ‘BEAMER_OUTER_THEME’
      The Beamer outer theme.
 
 ‘BEAMER_HEADER’
      Arbitrary lines inserted in the preamble, just before the
      ‘hyperref’ settings.
 
 ‘DESCRIPTION’
      The document description.  For long descriptions, use multiple
      ‘DESCRIPTION’ keywords.  By default, ‘hyperref’ inserts
      ‘DESCRIPTION’ as metadata.  Use ‘org-latex-hyperref-template’ to
      configure document metadata.  Use ‘org-latex-title-command’ to
      configure typesetting of description as part of front matter.
 
 ‘KEYWORDS’
      The keywords for defining the contents of the document.  Use
      multiple ‘KEYWORDS’ lines if necessary.  By default, ‘hyperref’
      inserts ‘KEYWORDS’ as metadata.  Use ‘org-latex-hyperref-template’
      to configure document metadata.  Use ‘org-latex-title-command’ to
      configure typesetting of keywords as part of front matter.
 
 ‘SUBTITLE’
      Document’s subtitle.  For typesetting, use
      ‘org-beamer-subtitle-format’ string.  Use
      ‘org-latex-hyperref-template’ to configure document metadata.  Use
      ‘org-latex-title-command’ to configure typesetting of subtitle as
      part of front matter.

 13.8.3 Frames and Blocks in Beamer
 ----------------------------------
 
 Org transforms heading levels into Beamer’s sectioning elements, frames
 and blocks.  Any Org tree with a not-too-deep-level nesting should in
 principle be exportable as a Beamer presentation.
 
    • Org headlines become Beamer frames when the heading level in Org is
      equal to ‘org-beamer-frame-level’ or ‘H’ value in a ‘OPTIONS’ line
      (see *note Export Settings::).
 
      Org overrides headlines to frames conversion for the current tree
      of an Org file if it encounters the ‘BEAMER_ENV’ property set to
      ‘frame’ or ‘fullframe’.  Org ignores whatever
      ‘org-beamer-frame-level’ happens to be for that headline level in
      the Org tree.  In Beamer terminology, a full frame is a frame
      without its title.
 
    • Org exports a Beamer frame’s objects as block environments.  Org
      can enforce wrapping in special block types when ‘BEAMER_ENV’
      property is set(1).  For valid values see
      ‘org-beamer-environments-default’.  To add more values, see
      ‘org-beamer-environments-extra’.
 
    • If ‘BEAMER_ENV’ is set to ‘appendix’, Org exports the entry as an
      appendix.  When set to ‘note’, Org exports the entry as a note
      within the frame or between frames, depending on the entry’s
      heading level.  When set to ‘noteNH’, Org exports the entry as a
      note without its title.  When set to ‘againframe’, Org exports the
      entry with ‘\againframe’ command, which makes setting the
      ‘BEAMER_REF’ property mandatory because ‘\againframe’ needs frame
      to resume.
 
      When ‘ignoreheading’ is set, Org export ignores the entry’s
      headline but not its content.  This is useful for inserting content
      between frames.  It is also useful for properly closing a ‘column’
      environment.
 
      When ‘BEAMER_ACT’ is set for a headline, Org export translates that
      headline as an overlay or action specification.  When enclosed in
      square brackets, Org export makes the overlay specification a
      default.  Use ‘BEAMER_OPT’ to set any options applicable to the
      current Beamer frame or block.  The Beamer export backend wraps
      with appropriate angular or square brackets.  It also adds the
      ‘fragile’ option for any code that may require a verbatim block.
 
      To create a column on the Beamer slide, use the ‘BEAMER_COL’
      property for its headline in the Org file.  Set the value of
      ‘BEAMER_COL’ to a decimal number representing the fraction of the
      total text width.  Beamer export uses this value to set the
      column’s width and fills the column with the contents of the Org
      entry.  If the Org entry has no specific environment defined,
      Beamer export ignores the heading.  If the Org entry has a defined
      environment, Beamer export uses the heading as title.  Behind the
      scenes, Beamer export automatically handles LaTeX column
      separations for contiguous headlines.  To manually adjust them for
      any unique configurations needs, use the ‘BEAMER_ENV’ property.
 
    ---------- Footnotes ----------
 
    (1) If ‘BEAMER_ENV’ is set, Org export adds ‘B_environment’ tag to
 make it visible.  The tag serves as a visual aid and has no semantic
 relevance.

 13.8.4 Beamer specific syntax
 -----------------------------
 
 Since Org’s Beamer export backend is an extension of the LaTeX backend,
 it recognizes other LaTeX specific syntax—for example, ‘#+LATEX:’ or
 ‘#+ATTR_LATEX:’.  See *note LaTeX Export::, for details.
 
    Beamer export wraps the table of contents generated with ‘toc:t’
 ‘OPTION’ keyword in a ‘frame’ environment.  Beamer export does not wrap
 the table of contents generated with ‘TOC’ keyword (see *note Table of
 Contents::).  Use square brackets for specifying options.
 
      #+TOC: headlines [currentsection]
 
    Insert Beamer-specific code using the following constructs:
 
      #+BEAMER: \pause
 
      #+BEGIN_EXPORT beamer
        Only Beamer export backend exports this.
      #+END_EXPORT
 
      Text @@beamer:some code@@ within a paragraph.
 
    Inline constructs, such as the last one above, are useful for adding
 overlay specifications to objects with ‘bold’, ‘item’, ‘link’,
 ‘radio-target’ and ‘target’ types.  Enclose the value in angular
 brackets and place the specification at the beginning of the object as
 shown in this example:
 
      A *@@beamer:<2->@@useful* feature
 
    Beamer export recognizes the ‘ATTR_BEAMER’ keyword with the following
 attributes from Beamer configurations: ‘:environment’ for changing local
 Beamer environment, ‘:overlay’ for specifying Beamer overlays in angular
 or square brackets, and ‘:options’ for inserting optional arguments.
 
      #+ATTR_BEAMER: :environment nonindentlist
      - item 1, not indented
      - item 2, not indented
      - item 3, not indented
 
      #+ATTR_BEAMER: :overlay <+->
      - item 1
      - item 2
 
      #+ATTR_BEAMER: :options [Lagrange]
      Let $G$ be a finite group, and let $H$ be
      a subgroup of $G$.  Then the order of $H$ divides the order of $G$.

 13.9.1 HTML export commands
 ---------------------------
 
 ‘C-c C-e h h’ (‘org-html-export-to-html’)
 
      Export as HTML file with a ‘.html’ extension.  For ‘myfile.org’,
      Org exports to ‘myfile.html’, overwriting without warning.  ‘C-c
      C-e h o’ exports to HTML and opens it in a web browser.
 
 ‘C-c C-e h H’ (‘org-html-export-as-html’)
 
      Exports to a temporary buffer.  Does not create a file.
 
 
 File: org.info,  Node: HTML specific export settings,  Next: HTML doctypes,  Prev: HTML export commands,  Up: HTML Export
 
 13.9.2 HTML specific export settings
 ------------------------------------
 
 HTML export has a number of keywords, similar to the general options
 settings described in *note Export Settings::.
 
 ‘DESCRIPTION’
      This is the document’s description, which the HTML exporter inserts
      it as a HTML meta tag in the HTML file.  For long descriptions, use
      multiple ‘DESCRIPTION’ lines.  The exporter takes care of wrapping
      the lines properly.
 
      The exporter includes a number of other meta tags, which can be
      customized by modifying ‘org-html-meta-tags’.
 
 ‘HTML_DOCTYPE’
      Specify the document type, for example: HTML5 (‘org-html-doctype’).
 
 ‘HTML_CONTAINER’
      Specify the HTML container, such as ‘div’, for wrapping sections
      and elements (‘org-html-container-element’).
 
 ‘HTML_LINK_HOME’
      The URL for home link (‘org-html-link-home’).
 
 ‘HTML_LINK_UP’
      The URL for the up link of exported HTML pages
      (‘org-html-link-up’).
 
 ‘HTML_MATHJAX’
      Options for MathJax (‘org-html-mathjax-options’).  MathJax is used
      to typeset LaTeX math in HTML documents.  See *note Math formatting
      in HTML export::, for an example.
 
 ‘HTML_HEAD’
      Arbitrary lines for appending to the HTML document’s head
      (‘org-html-head’).
 
 ‘HTML_HEAD_EXTRA’
      More arbitrary lines for appending to the HTML document’s head
      (‘org-html-head-extra’).
 
 ‘KEYWORDS’
      Keywords to describe the document’s content.  HTML exporter inserts
      these keywords as HTML meta tags.  For long keywords, use multiple
      ‘KEYWORDS’ lines.
 
 ‘LATEX_HEADER’
      Arbitrary lines for appending to the preamble; HTML exporter
      appends when transcoding LaTeX fragments to images (see *note Math
      formatting in HTML export::).
 
 ‘SUBTITLE’
      The document’s subtitle.  HTML exporter formats subtitle if
      document type is ‘HTML5’ and the CSS has a ‘subtitle’ class.
 
    Some of these keywords are explained in more detail in the following
 sections of the manual.
 
 
 File: org.info,  Node: HTML doctypes,  Next: HTML preamble and postamble,  Prev: HTML specific export settings,  Up: HTML Export
 
 13.9.3 HTML doctypes
 --------------------
 
 Org can export to various (X)HTML flavors.
 
    Set the ‘org-html-doctype’ variable for different (X)HTML variants.
 Depending on the variant, the HTML exporter adjusts the syntax of HTML
 conversion accordingly.  Org includes the following ready-made variants:
 
    • ‘"html4-strict"’
    • ‘"html4-transitional"’
    • ‘"html4-frameset"’
    • ‘"xhtml-strict"’
    • ‘"xhtml-transitional"’
    • ‘"xhtml-frameset"’
    • ‘"xhtml-11"’
    • ‘"html5"’
    • ‘"xhtml5"’
 
 See the variable ‘org-html-doctype-alist’ for details.  The default is
 ‘"xhtml-strict"’.
 
    Org’s HTML exporter does not by default enable new block elements
 introduced with the HTML5 standard.  To enable them, set
 ‘org-html-html5-fancy’ to non-‘nil’.  Or use an ‘OPTIONS’ line in the
 file to set ‘html5-fancy’.
 
    HTML5 documents can have arbitrary ‘#+BEGIN’ ... ‘#+END’ blocks.  For
 example:
 
      #+BEGIN_aside
        Lorem ipsum
      #+END_aside
 
 exports to:
 
      <aside>
        <p>Lorem ipsum</p>
      </aside>
 
 while this:
 
      #+ATTR_HTML: :controls controls :width 350
      #+BEGIN_video
      #+HTML: <source src="movie.mp4" type="video/mp4">
      #+HTML: <source src="movie.ogg" type="video/ogg">
      Your browser does not support the video tag.
      #+END_video
 
 exports to:
 
      <video controls="controls" width="350">
        <source src="movie.mp4" type="video/mp4">
        <source src="movie.ogg" type="video/ogg">
        <p>Your browser does not support the video tag.</p>
      </video>
 
    When special blocks do not have a corresponding HTML5 element, the
 HTML exporter reverts to standard translation (see
 ‘org-html-html5-elements’).  For example, ‘#+BEGIN_lederhosen’ exports
 to ‘<div class="lederhosen">’.
 
    Special blocks cannot have headlines.  For the HTML exporter to wrap
 the headline and its contents in ‘<section>’ or ‘<article>’ tags, set
 the ‘HTML_CONTAINER’ property for the headline.
 
 
 File: org.info,  Node: HTML preamble and postamble,  Next: Bare HTML,  Prev: HTML doctypes,  Up: HTML Export
 
 13.9.4 HTML preamble and postamble
 ----------------------------------
 
 The HTML exporter has delineations for preamble and postamble.  The
 default value for ‘org-html-preamble’ is ‘t’, which makes the HTML
 exporter insert the preamble.  See the variable
 ‘org-html-preamble-format’ for the format string.
 
    Set ‘org-html-preamble’ to a string to override the default format
 string.  If set to a function, the HTML exporter expects the function to
 return a string upon execution.  The HTML exporter inserts this string
 in the preamble.  The HTML exporter does not insert a preamble if
 ‘org-html-preamble’ is set ‘nil’.
 
    The above also applies to ‘org-html-postamble’ and
 ‘org-html-postamble-format’.  In addition, ‘org-html-postamble’ can be
 set to ‘auto’ (its default value), which makes the HTML exporter build a
 postamble from looking up author’s name, email address, creator’s name,
 and date.

 13.9.5 Exporting to minimal HTML
 --------------------------------
 
 If you want to output a minimal HTML file, with no CSS, no Javascript,
 no preamble or postamble, here are the variable you would need to set:
 
      (setq org-html-head ""
            org-html-head-extra ""
            org-html-head-include-default-style nil
            org-html-head-include-scripts nil
            org-html-preamble nil
            org-html-postamble nil
            org-html-use-infojs nil)
 
 
 File: org.info,  Node: Quoting HTML tags,  Next: Headlines in HTML export,  Prev: Bare HTML,  Up: HTML Export
 
 13.9.6 Quoting HTML tags
 ------------------------
 
 The HTML export backend transforms ‘<’ and ‘>’ to ‘&lt;’ and ‘&gt;’.  To
 include raw HTML code in the Org file so the HTML export backend can
 insert that HTML code in the output, use this inline syntax:
 ‘@@html:...@@’.  For example:
 
      @@html:<b>@@bold text@@html:</b>@@
 
    For larger raw HTML code blocks, use these HTML export code blocks:
 
      #+HTML: Literal HTML code for export
 
      #+BEGIN_EXPORT html
        All lines between these markers are exported literally
      #+END_EXPORT
 
 
 File: org.info,  Node: Headlines in HTML export,  Next: Links in HTML export,  Prev: Quoting HTML tags,  Up: HTML Export
 
 13.9.7 Headlines in HTML export
 -------------------------------
 
 Headlines are exported to ‘<h1>’, ‘<h2>’, etc.  Each headline gets the
 ‘id’ attribute from ‘CUSTOM_ID’ property, or a unique generated value,
 see *note Internal Links::.
 
    When ‘org-html-self-link-headlines’ is set to a non-‘nil’ value, the
 text of the headlines is also wrapped in ‘<a>’ tags.  These tags have a
 ‘href’ attribute making the headlines link to themselves.
 
 
 File: org.info,  Node: Links in HTML export,  Next: Tables in HTML export,  Prev: Headlines in HTML export,  Up: HTML Export
 
 13.9.8 Links in HTML export
 ---------------------------
 
 The HTML export backend transforms Org’s internal links (see *note
 Internal Links::) to equivalent HTML links in the output.  The backend
 similarly handles Org’s automatic links created by radio targets (see
 *note Radio Targets::) similarly.  For Org links to external files, the
 backend transforms the links to _relative_ paths.
 
    For Org links to other ‘.org’ files, the backend automatically
 changes the file extension to ‘.html’ and makes file paths relative.  If
 the ‘.org’ files have an equivalent ‘.html’ version at the same
 location, then the converted links should work without any further
 manual intervention.  However, to disable this automatic path
 translation, set ‘org-html-link-org-files-as-html’ to ‘nil’.  When
 disabled, the HTML export backend substitutes the ID-based links in the
 HTML output.  For more about linking files when publishing to a
 directory, see *note Publishing links::.
 
    Org files can also have special directives to the HTML export
 backend.  For example, by using ‘#+ATTR_HTML’ lines to specify new
 format attributes to ‘<a>’ or ‘<img>’ tags.  This example shows changing
 the link’s title and style:
 
      #+ATTR_HTML: :title The Org mode website :style color:red;
      [[https://orgmode.org]]
 
 
 File: org.info,  Node: Tables in HTML export,  Next: Images in HTML export,  Prev: Links in HTML export,  Up: HTML Export
 
 13.9.9 Tables in HTML export
 ----------------------------
 
 The HTML export backend uses ‘org-html-table-default-attributes’ when
 exporting Org tables to HTML.  By default, the exporter does not draw
 frames and cell borders.  To change for this for a table, use the
 following lines before the table in the Org file:
 
      #+CAPTION: This is a table with lines around and between cells
      #+ATTR_HTML: :border 2 :rules all :frame border
 
    The HTML export backend preserves column groupings in Org tables (see
 *note Column Groups::) when exporting to HTML.
 
    Additional options for customizing tables for HTML export.
 
 ‘org-html-table-align-individual-fields’
      Non-‘nil’ attaches style attributes for alignment to each table
      field.
 
 ‘org-html-table-caption-above’
      Non-‘nil’ places caption string at the beginning of the table.
 
 ‘org-html-table-data-tags’
      Opening and ending tags for table data fields.
 
 ‘org-html-table-default-attributes’
      Default attributes and values for table tags.
 
 ‘org-html-table-header-tags’
      Opening and ending tags for table’s header fields.
 
 ‘org-html-table-row-tags’
      Opening and ending tags for table rows.
 
 ‘org-html-table-use-header-tags-for-first-column’
      Non-‘nil’ formats column one in tables with header tags.
 
 
 File: org.info,  Node: Images in HTML export,  Next: Math formatting in HTML export,  Prev: Tables in HTML export,  Up: HTML Export
 
 13.9.10 Images in HTML export
 -----------------------------
 
 The HTML export backend has features to convert Org image links to HTML
 inline images and HTML clickable image links.
 
    When the link in the Org file has no description, the HTML export
 backend by default in-lines that image.  For example:
 ‘[[file:myimg.jpg]]’ is in-lined, while ‘[[file:myimg.jpg][the image]]’
 links to the text, ‘the image’.  For more details, see the variable
 ‘org-html-inline-images’.
 
    On the other hand, if the description part of the Org link is itself
 another link, such as ‘file:’ or ‘http:’ URL pointing to an image, the
 HTML export backend in-lines this image and links to the main image.
 This Org syntax enables the backend to link low-resolution thumbnail to
 the high-resolution version of the image, as shown in this example:
 
      [[file:highres.jpg][file:thumb.jpg]]
 
    To change attributes of in-lined images, use ‘#+ATTR_HTML’ lines in
 the Org file.  This example shows realignment to right, and adds ‘alt’
 and ‘title’ attributes in support of text viewers and modern web
 accessibility standards.
 
      #+CAPTION: A black cat stalking a spider
      #+ATTR_HTML: :alt cat/spider image :title Action! :align right
      [[./img/a.jpg]]
 
    The HTML export backend copies the ‘http’ links from the Org file
 as-is.
 
 
 File: org.info,  Node: Math formatting in HTML export,  Next: Text areas in HTML export,  Prev: Images in HTML export,  Up: HTML Export
 
 13.9.11 Math formatting in HTML export
 --------------------------------------
 
 LaTeX math snippets (see *note LaTeX fragments::) can be displayed in
 two different ways on HTML pages.  The default is to use the MathJax
 (https://www.mathjax.org), which should work out of the box with
 Org(1)(2).  Some MathJax display options can be configured via
 ‘org-html-mathjax-options’, or in the buffer.  For example, with the
 following settings,
 
      #+HTML_MATHJAX: align: left indent: 5em tagside: left
 
 equation labels are displayed on the left margin and equations are five
 em from the left margin.
 
    See the docstring of ‘org-html-mathjax-options’ for all supported
 variables.  The MathJax template can be configure via
 ‘org-html-mathjax-template’.
 
    If you prefer, you can also request that LaTeX fragments are
 processed into small images that will be inserted into the browser page.
 Before the availability of MathJax, this was the default method for Org
 files.  This method requires that the dvipng program, dvisvgm or
 ImageMagick suite is available on your system.  You can still get this
 processing with
 
      #+OPTIONS: tex:dvipng
 
      #+OPTIONS: tex:dvisvgm
 
 or
 
      #+OPTIONS: tex:imagemagick
 
    ---------- Footnotes ----------
 
    (1) By default, Org loads MathJax from jsDelivr
 (https://www.jsdelivr.com/), as recommended in Getting Started with
 MathJax Components (https://docs.mathjax.org/en/latest/web/start.html).
 
    (2) Please note that exported formulas are part of an HTML document,
 and that signs such as ‘<’, ‘>’, or ‘&’ have special meanings.  See
 MathJax TeX and LaTeX in HTML documents
 (https://docs.mathjax.org/en/latest/input/tex/html.html#tex-and-latex-in-html-documents).

 13.9.12 Text areas in HTML export
 ---------------------------------
 
 Before Org mode’s Babel, one popular approach to publishing code in HTML
 was by using ‘:textarea’.  The advantage of this approach was that
 copying and pasting was built into browsers with simple JavaScript
 commands.  Even editing before pasting was made simple.
 
    The HTML export backend can create such text areas.  It requires an
 ‘#+ATTR_HTML’ line as shown in the example below with the ‘:textarea’
 option.  This must be followed by either an example or a source code
 block.  Other Org block types do not honor the ‘:textarea’ option.
 
    By default, the HTML export backend creates a text area 80 characters
 wide and height just enough to fit the content.  Override these defaults
 with ‘:width’ and ‘:height’ options on the ‘#+ATTR_HTML’ line.
 
      #+ATTR_HTML: :textarea t :width 40
      #+BEGIN_EXAMPLE
        (defun org-xor (a b)
           "Exclusive or."
           (if a (not b) b))
      #+END_EXAMPLE

 13.9.13 CSS support
 -------------------
 
 You can modify the CSS style definitions for the exported file.  The
 HTML exporter assigns the following special CSS classes(1) to
 appropriate parts of the document—your style specifications may change
 these, in addition to any of the standard classes like for headlines,
 tables, etc.
 
 ‘p.author’             author information, including email
 ‘p.date’               publishing date
 ‘p.creator’            creator info, about org mode version
 ‘.title’               document title
 ‘.subtitle’            document subtitle
 ‘.todo’                TODO keywords, all not-done states
 ‘.done’                the DONE keywords, all states that count as done
 ‘.WAITING’             each TODO keyword also uses a class named after itself
 ‘.timestamp’           timestamp
 ‘.timestamp-kwd’       keyword associated with a timestamp, like ‘SCHEDULED’
 ‘.timestamp-wrapper’   span around keyword plus timestamp
 ‘.tag’                 tag in a headline
 ‘._HOME’               each tag uses itself as a class, “@” replaced by “_”
 ‘.target’              target for links
 ‘.linenr’              the line number in a code example
 ‘.code-highlighted’    for highlighting referenced code lines
 ‘div.outline-N’        div for outline level N (headline plus text)
 ‘div.outline-text-N’   extra div for text at outline level N
 ‘.section-number-N’    section number in headlines, different for each level
 ‘.figure-number’       label like “Figure 1:”
 ‘.table-number’        label like “Table 1:”
 ‘.listing-number’      label like “Listing 1:”
 ‘div.figure’           how to format an in-lined image
 ‘pre.src’              formatted source code
 ‘pre.example’          normal example
 ‘p.verse’              verse paragraph
 ‘div.footnotes’        footnote section headline
 ‘p.footnote’           footnote definition paragraph, containing a footnote
 ‘.footref’             a footnote reference number (always a <sup>)
 ‘.footnum’             footnote number in footnote definition (always <sup>)
 ‘.org-svg’             default class for a linked ‘.svg’ image
 
    The HTML export backend includes a compact default style in each
 exported HTML file.  To override the default style with another style,
 use these keywords in the Org file.  They will replace the global
 defaults the HTML exporter uses.
 
      #+HTML_HEAD: <link rel="stylesheet" type="text/css" href="style1.css" />
      #+HTML_HEAD_EXTRA: <link rel="alternate stylesheet" type="text/css" href="style2.css" />
 
    To just turn off the default style, customize
 ‘org-html-head-include-default-style’ variable, or use this option line
 in the Org file.
 
      #+OPTIONS: html-style:nil
 
    For longer style definitions, either use several ‘HTML_HEAD’ and
 ‘HTML_HEAD_EXTRA’ keywords, or use ‘<style> ... </style>’ blocks around
 them.  Both of these approaches can avoid referring to an external file.
 
    In order to add styles to a subtree, use the ‘HTML_CONTAINER_CLASS’
 property to assign a class to the tree.  In order to specify CSS styles
 for a particular headline, you can use the ID specified in a ‘CUSTOM_ID’
 property.  You can also assign a specific class to a headline with the
 ‘HTML_HEADLINE_CLASS’ property.
 
    Never change the ‘org-html-style-default’ constant.  Instead use
 other simpler ways of customizing as described above.

 13.9.14 JavaScript supported display of web pages
 -------------------------------------------------
 
 Sebastian Rose has written a JavaScript program especially designed to
 allow two different ways of viewing HTML files created with Org.  One is
 an _Info_-like mode where each section is displayed separately and
 navigation can be done with the ‘n’ and ‘p’ keys, and some other keys as
 well, press ‘?’ for an overview of the available keys.  The second one
 has a _folding_ view, much like Org provides inside Emacs.  The script
 is available at <https://orgmode.org/org-info.js> and the documentation
 at <https://orgmode.org/worg/code/org-info-js/>.  The script is hosted
 on <https://orgmode.org>, but for reliability, prefer installing it on
 your own web server.
 
    To use this program, just add this line to the Org file:
 
      #+INFOJS_OPT: view:info toc:nil
 
 The HTML header now has the code needed to automatically invoke the
 script.  For setting options, use the syntax from the above line for
 options described below:
 
 ‘path:’
      The path to the script.  The default is to grab the script from
      <https://orgmode.org/org-info.js>, but you might want to have a
      local copy and use a path like ‘../scripts/org-info.js’.
 
 ‘view:’
      Initial view when the website is first shown.  Possible values are:
 
      ‘info’       Info-like interface with one section per page
      ‘overview’   Folding interface, initially showing only top-level
      ‘content’    Folding interface, starting with all headlines visible
      ‘showall’    Folding interface, all headlines and text visible
 
 ‘sdepth:’
      Maximum headline level still considered as an independent section
      for info and folding modes.  The default is taken from
      ‘org-export-headline-levels’, i.e., the ‘H’ switch in ‘OPTIONS’.
      If this is smaller than in ‘org-export-headline-levels’, each
      info/folding section can still contain child headlines.
 
 ‘toc:’
      Should the table of contents _initially_ be visible?  Even when
      ‘nil’, you can always get to the “toc” with ‘i’.
 
 ‘tdepth:’
      The depth of the table of contents.  The defaults are taken from
      the variables ‘org-export-headline-levels’ and
      ‘org-export-with-toc’.
 
 ‘ftoc:’
      Does the CSS of the page specify a fixed position for the “toc”?
      If yes, the toc is displayed as a section.
 
 ‘ltoc:’
      Should there be short contents (children) in each section?  Make
      this ‘above’ if the section should be above initial text.
 
 ‘mouse:’
      Headings are highlighted when the mouse is over them.  Should be
      ‘underline’ (default) or a background color like ‘#cccccc’.
 
 ‘buttons:’
      Should view-toggle buttons be everywhere?  When ‘nil’ (the
      default), only one such button is present.
 
    You can choose default values for these options by customizing the
 variable ‘org-infojs-options’.  If you always want to apply the script
 to your pages, configure the variable ‘org-export-html-use-infojs’.

 13.10 LaTeX Export
 ==================
 
 The LaTeX export backend can handle complex documents, incorporate
 standard or custom LaTeX document classes, generate documents using
 alternate LaTeX engines, and produce fully linked PDF files with
 indexes, bibliographies, and tables of contents, destined for
 interactive online viewing or high-quality print publication.
 
    While the details are covered in-depth in this section, here are some
 quick references to variables for the impatient: for engines, see
 ‘org-latex-compiler’; for build sequences, see ‘org-latex-pdf-process’;
 for packages, see ‘org-latex-default-packages-alist’ and
 ‘org-latex-packages-alist’.
 
    An important note about the LaTeX export backend: it is sensitive to
 blank lines in the Org document.  That’s because LaTeX itself depends on
 blank lines to tell apart syntactical elements, such as paragraphs.
 
    The following sections expect users to be familiar with common LaTeX
 terminology.  You may refer to <https://tug.org/begin.html> to get
 familiar with LaTeX basics.  Users with LaTeX installed may also run
 ‘texdoc latex’ from terminal to open LaTeX introduction (1)

 13.10.1 LaTeX/PDF export commands
 ---------------------------------
 
 ‘C-c C-e l l’ (‘org-latex-export-to-latex’)
      Export to a LaTeX file with a ‘.tex’ extension.  For ‘myfile.org’,
      Org exports to ‘myfile.tex’, overwriting without warning.
 
 ‘C-c C-e l L’ (‘org-latex-export-as-latex’)
      Export to a temporary buffer.  Do not create a file.
 
 ‘C-c C-e l p’ (‘org-latex-export-to-pdf’)
      Export as LaTeX file and convert it to PDF file.
 
 ‘C-c C-e l o’
      Export as LaTeX file and convert it to PDF, then open the PDF using
      the default viewer.
 
 ‘M-x org-export-region-as-latex’
      Convert the region to LaTeX under the assumption that it was in Org
      mode syntax before.  This is a global command that can be invoked
      in any buffer.
 
    The LaTeX export backend can use any of these LaTeX engines:
 ‘pdflatex’, ‘xelatex’, and ‘lualatex’.  These engines compile LaTeX
 files with different compilers, packages, and output options.  The LaTeX
 export backend finds the compiler version to use from
 ‘org-latex-compiler’ variable or the ‘#+LATEX_COMPILER’ keyword in the
 Org file.  See the docstring for the ‘org-latex-default-packages-alist’
 for loading packages with certain compilers.  Also see
 ‘org-latex-bibtex-compiler’ to set the bibliography compiler(1).
 
    ---------- Footnotes ----------
 
    (1) This does not allow setting different bibliography compilers for
 different files.  However, “smart” LaTeX compilation systems, such as
 latexmk, can select the correct bibliography compiler.

 13.10.2 LaTeX specific export settings
 --------------------------------------
 
 The LaTeX export backend has several additional keywords for customizing
 LaTeX output.  Setting these keywords works similar to the general
 options (see *note Export Settings::).
 
 ‘DESCRIPTION’
      The document’s description.  The description along with author
      name, keywords, and related file metadata are inserted in the
      output file by the hyperref package.  See
      ‘org-latex-hyperref-template’ for customizing metadata items.  See
      ‘org-latex-title-command’ for typesetting description into the
      document’s front matter.  Use multiple ‘DESCRIPTION’ keywords for
      long descriptions.
 
 ‘LANGUAGE’
 
      Language code of the primary document language.  When ‘LANGUAGE’
      keyword is not not specified use the value of
      ‘org-export-default-language’ (by default - ‘en’, American English)
 
      The list of language codes supported by Org is stored in the
      variable ‘org-latex-language-alist’.
 
      In order to be effective, the ‘babel’ or ‘polyglossia’
      packages—according to the LaTeX compiler used—must be loaded with
      the appropriate language as argument.  This can be accomplished by
      modifying the ‘org-latex-packages-alist’ variable, e.g., with the
      following snippet (note that ‘polyglossia’ does not work with
      pdfLaTeX):
 
           (add-to-list 'org-latex-packages-alist
                        '("AUTO" "babel" t ("pdflatex" "xelatex" "lualatex")))
           (add-to-list 'org-latex-packages-alist
                        '("AUTO" "polyglossia" t ("xelatex" "lualatex")))
 
 ‘LATEX_CLASS’
      This is LaTeX document class, such as _article_, _report_, _book_,
      and so on, which contain predefined preamble and headline level
      mapping that the LaTeX export backend needs.  The backend reads the
      default class name from the ‘org-latex-default-class’ variable.
      Org has _article_ as the default class.  A valid default class must
      be an element of ‘org-latex-classes’.
 
 ‘LATEX_CLASS_OPTIONS’
      Options the LaTeX export backend uses when calling the LaTeX
      document class.
 
 ‘LATEX_COMPILER’
      The compiler, such as ‘pdflatex’, ‘xelatex’, ‘lualatex’, for
      producing the PDF.  See ‘org-latex-compiler’.
 
 ‘LATEX_HEADER’
 ‘LATEX_HEADER_EXTRA’
      Arbitrary lines to add to the document’s preamble, before the
      hyperref settings.  See ‘org-latex-classes’ for adjusting the
      structure and order of the LaTeX headers.
 
 ‘KEYWORDS’
      The keywords for the document.  The description along with author
      name, keywords, and related file metadata are inserted in the
      output file by the hyperref package.  See
      ‘org-latex-hyperref-template’ for customizing metadata items.  See
      ‘org-latex-title-command’ for typesetting description into the
      document’s front matter.  Use multiple ‘KEYWORDS’ lines if
      necessary.
 
 ‘SUBTITLE’
      The document’s subtitle.  It is typeset as per
      ‘org-latex-subtitle-format’.  If ‘org-latex-subtitle-separate’ is
      non-‘nil’, it is typed outside of the ‘\title’ macro.  See
      ‘org-latex-hyperref-template’ for customizing metadata items.  See
      ‘org-latex-title-command’ for typesetting description into the
      document’s front matter.
 
    The following sections have further details.

 13.10.3 LaTeX header and sectioning structure
 ---------------------------------------------
 
 The LaTeX export backend converts the first three of Org’s outline
 levels into LaTeX headlines.  The remaining Org levels are exported as
 lists.  To change this globally for the cut-off point between levels and
 lists, (see *note Export Settings::).
 
    By default, the LaTeX export backend uses the _article_ class.
 
    To change the default class globally, edit ‘org-latex-default-class’.
 To change the default class locally in an Org file, add option lines
 ‘#+LATEX_CLASS: myclass’.  To change the default class for just a part
 of the Org file, set a subtree property, ‘EXPORT_LATEX_CLASS’.  The
 class name entered here must be valid member of ‘org-latex-classes’.
 This variable defines a header template for each class into which the
 exporter splices the values of ‘org-latex-default-packages-alist’ and
 ‘org-latex-packages-alist’.  Use the same three variables to define
 custom sectioning or custom classes.
 
    The LaTeX export backend sends the ‘LATEX_CLASS_OPTIONS’ keyword and
 ‘EXPORT_LATEX_CLASS_OPTIONS’ property as options to the LaTeX
 ‘\documentclass’ macro.  The options and the syntax for specifying them,
 including enclosing them in square brackets, follow LaTeX conventions.
 
      #+LATEX_CLASS_OPTIONS: [a4paper,11pt,twoside,twocolumn]
 
    The LaTeX export backend appends values from ‘LATEX_HEADER’ and
 ‘LATEX_HEADER_EXTRA’ keywords to the LaTeX header.  The docstring for
 ‘org-latex-classes’ explains in more detail.  Also note that LaTeX
 export backend does not append ‘LATEX_HEADER_EXTRA’ to the header when
 previewing LaTeX snippets (see *note Previewing LaTeX fragments::).
 
    A sample Org file with the above headers:
 
      #+LATEX_CLASS: article
      #+LATEX_CLASS_OPTIONS: [a4paper]
      #+LATEX_HEADER: \usepackage{xyz}
 
      * Headline 1
        some text
      * Headline 2
        some more text
 
    LaTeX packages ‘babel’ or ‘polyglossia’ can also be loaded in a
 document.  The “AUTO” string will be replaced in both cases by the
 appropriate value for the ‘LANGUAGE’ keyword, if present in the
 document, or by the value of ‘org-export-default-language’.  Let’s see
 some examples in one or another case.
 
    ‘Babel’ accepts the classic syntax and (in addition) the new syntax
 with the ‘\babelprovide’ command to load the languages using the new
 ‘INI’ files procedure.  Keep in mind that there are a number of
 languages that are only served in babel using ‘INI’ files, so they
 cannot be declared using the classic syntax, but only using the
 ‘\babelprovide’ command (see
 <https://mirrors.ctan.org/macros/latex/required/babel/base/babel.pdf>).
 Valid usage examples could be:
 
      #+LATEX_HEADER: \usepackage[french,italian,AUTO]{babel}
 
    where “AUTO” is the main language.  But it can also be loaded using
 the ‘\babelprovide’ command:
 
      #+LATEX_HEADER: \usepackage[french,italian]{babel}
      #+LATEX_HEADER: \babelprovide[import, main]{AUTO}
 
    ‘Polyglossia’, for this procedure to be effective, must be loaded
 using the same ‘babel’ classic syntax (but note that _this is not_ the
 actual polyglossia syntax).  For example, suppose a document declares
 Polytonic Greek as the primary language, and French as the secondary
 language.  In this case, it would be expressed as:
 
      #+LANGUAGE: el-polyton
      #+LATEX_HEADER: \usepackage[french,AUTO]{polyglossia}
 
    This would produce in LaTeX (with the actual ‘polyglossia’ syntax):
 
      \usepackage{polyglossia}
      \setmainlanguage[variant=polytonic]{greek}
      \setotherlanguage{french}

 13.10.4 Quoting LaTeX code
 --------------------------
 
 When the available LaTeX export customizations are not sufficient to
 fine-tune the desired output, it is possible to insert any arbitrary
 LaTeX code (see *note Embedded LaTeX::).  There are three ways to embed
 such code in the Org file and they all use different quoting syntax.
 
    Inserting in-line quoted with @ symbols:
 
      Code embedded in-line @@latex:any arbitrary LaTeX code@@ in a paragraph.
 
    Inserting as one or more keyword lines in the Org file:
 
      #+LATEX: any arbitrary LaTeX code
 
    Inserting as an export block in the Org file, where the backend
 exports any code between begin and end markers:
 
      #+BEGIN_EXPORT latex
        any arbitrary LaTeX code
      #+END_EXPORT
 
 
 File: org.info,  Node: Tables in LaTeX export,  Next: Images in LaTeX export,  Prev: Quoting LaTeX code,  Up: LaTeX Export
 
 13.10.5 Tables in LaTeX export
 ------------------------------
 
 The LaTeX export backend can pass several LaTeX attributes for table
 contents and layout.  Besides specifying a label (see *note Internal
 Links::) and a caption (see *note Captions::), the other valid LaTeX
 attributes include:
 
 ‘:mode’
      The LaTeX export backend wraps the table differently depending on
      the mode for accurate rendering of math symbols.  Mode is either
      ‘table’, ‘math’, ‘inline-math’, ‘verbatim’ or ‘tabbing’.
 
      For ‘math’ or ‘inline-math’ mode, LaTeX export backend wraps the
      table in a math environment, but every cell in it is exported
      as-is.  For ‘tabbing’ the LaTeX tabbing environment is used and the
      correct tabbing delimiters ‘\>’ are used.  The LaTeX export backend
      determines the default mode from ‘org-latex-default-table-mode’.
      The LaTeX export backend merges contiguous tables in the same mode
      into a single environment.
 
 ‘:environment’
      Set the default LaTeX table environment for the LaTeX export
      backend to use when exporting Org tables.  Common LaTeX table
      environments are provided by these packages: tabularx, longtable,
      array, tabu, and bmatrix.  For packages, such as tabularx and tabu,
      or any newer replacements, include them in the
      ‘org-latex-packages-alist’ variable so the LaTeX export backend can
      insert the appropriate load package headers in the converted LaTeX
      file.  Look in the docstring for the ‘org-latex-packages-alist’
      variable for configuring these packages for LaTeX snippet previews,
      if any.
 
 ‘:caption’
      Use ‘CAPTION’ keyword to set a simple caption for a table (see
      *note Captions::).  For custom captions, use ‘:caption’ attribute,
      which accepts raw LaTeX code.  ‘:caption’ value overrides ‘CAPTION’
      value.
 
 ‘:float’
 ‘:placement’
      The table environments by default are not floats in LaTeX.  To make
      them floating objects use ‘:float’ with one of the following
      options: ‘t’ (for a default ‘table’ environment), ‘sideways’ (for a
      ‘sidewaystable’ environment), ‘multicolumn’ (to span the table
      across multiple columns of a page in a ‘table*’ environment) and
      ‘nil’.  In addition to these three values, ‘:float’ can pass
      through any arbitrary value, for example a user-defined float type
      with the ‘float’ LaTeX package.
 
      LaTeX floats can also have additional layout ‘:placement’
      attributes.  These are the usual ‘[h t b p ! H]’ permissions
      specified in square brackets.  Note that for ‘:float sideways’
      tables, the LaTeX export backend ignores ‘:placement’ attributes.
 
 ‘:align’
 ‘:font’
 ‘:width’
      The LaTeX export backend uses these attributes for regular tables
      to set their alignments, fonts, and widths.
 
 ‘:options’
      The ‘:options’ attribute allows adding an optional argument with a
      list of various table options (between brackets in LaTeX export),
      since certain tabular environments, such as longtblr of the
      tabularray LaTeX package, provides this structure.  For example:
      ‘:options remark{Note}={note},remark{Source}={source}’.
 
 ‘:spread’
      When ‘:spread’ is non-‘nil’, the LaTeX export backend spreads or
      shrinks the table by the ‘:width’ for tabu and longtabu
      environments.  ‘:spread’ has no effect if ‘:width’ is not set.
 
 ‘:booktabs’
 ‘:center’
 ‘:rmlines’
      All three commands are toggles.  ‘:booktabs’ brings in modern
      typesetting enhancements to regular tables.  The booktabs package
      has to be loaded through ‘org-latex-packages-alist’.  ‘:center’ is
      for centering the table.  ‘:rmlines’ removes all but the very first
      horizontal line made of ASCII characters from “table.el” tables
      only.
 
 ‘:math-prefix’
 ‘:math-suffix’
 ‘:math-arguments’
      The LaTeX export backend inserts ‘:math-prefix’ string value in a
      math environment before the table.  The LaTeX export backend
      inserts ‘:math-suffix’ string value in a math environment after the
      table.  The LaTeX export backend inserts ‘:math-arguments’ string
      value between the macro name and the table’s contents.
      ‘:math-arguments’ comes in use for matrix macros that require more
      than one argument, such as ‘qbordermatrix’.
 
    LaTeX table attributes help formatting tables for a wide range of
 situations, such as matrix product or spanning multiple pages:
 
      #+ATTR_LATEX: :environment longtable :align l|lp{3cm}r|l
      | ... | ... |
      | ... | ... |
 
      #+ATTR_LATEX: :mode math :environment bmatrix :math-suffix \times
      | a | b |
      | c | d |
      #+ATTR_LATEX: :mode math :environment bmatrix
      | 1 | 2 |
      | 3 | 4 |
 
    Set the caption with the LaTeX command
 ‘\bicaption{HeadingA}{HeadingB}’:
 
      #+ATTR_LATEX: :caption \bicaption{HeadingA}{HeadingB}
      | ... | ... |
      | ... | ... |
 
 
 File: org.info,  Node: Images in LaTeX export,  Next: Plain lists in LaTeX export,  Prev: Tables in LaTeX export,  Up: LaTeX Export
 
 13.10.6 Images in LaTeX export
 ------------------------------
 
 The LaTeX export backend processes image links in Org files that do not
 have descriptions, such as these links ‘[[file:img.jpg]]’ or
 ‘[[./img.jpg]]’, as direct image insertions in the final PDF output.  In
 the PDF, they are no longer links but actual images embedded on the
 page.  The LaTeX export backend uses ‘\includegraphics’ macro to insert
 the image.  But for TikZ (<https://sourceforge.net/projects/pgf/>)
 images, the backend uses an ‘\input’ macro wrapped within a
 ‘tikzpicture’ environment.
 
    For specifying image ‘:width’, ‘:height’, ‘:scale’ and other
 ‘:options’, use this syntax:
 
      #+ATTR_LATEX: :width 5cm :options angle=90
      [[./img/sed-hr4049.pdf]]
 
    A ‘:scale’ attribute overrides both ‘:width’ and ‘:height’
 attributes.
 
    For custom commands for captions, use the ‘:caption’ attribute.  It
 overrides the default ‘#+CAPTION’ value:
 
      #+ATTR_LATEX: :caption \bicaption{HeadingA}{HeadingB}
      [[./img/sed-hr4049.pdf]]
 
    When captions follow the method as described in *note Captions::, the
 LaTeX export backend wraps the picture in a floating ‘figure’
 environment.  To float an image without specifying a caption, set the
 ‘:float’ attribute to one of the following:
 
 ‘t’
      For a default ‘figure’ environment.
 
 ‘multicolumn’
      To span the image across multiple columns of a page; the backend
      wraps the image in a ‘figure*’ environment.
 
 ‘wrap’
      For text to flow around the image on the right; the figure occupies
      the left half of the page.
 
 ‘sideways’
      For a new page with the image sideways, rotated ninety degrees, in
      a ‘sidewaysfigure’ environment; overrides ‘:placement’ setting.
 
 ‘nil’
      To avoid a ‘:float’ even if using a caption.
 
 Any arbitrary value
      For example, a user-defined float type with the ‘float’ LaTeX
      package.
 
    Use the ‘placement’ attribute to modify a floating environment’s
 placement.
 
      #+ATTR_LATEX: :float wrap :width 0.38\textwidth :placement {r}{0.4\textwidth}
      [[./img/hst.png]]
 
    The LaTeX export backend centers all images by default.  Setting
 ‘:center’ to ‘nil’ disables centering.  To disable centering globally,
 set ‘org-latex-images-centered’ to ‘nil’.
 
    Set the ‘:comment-include’ attribute to non-‘nil’ value for the LaTeX
 export backend to comment out the ‘\includegraphics’ macro.
 
 
 File: org.info,  Node: Plain lists in LaTeX export,  Next: Source blocks in LaTeX export,  Prev: Images in LaTeX export,  Up: LaTeX Export
 
 13.10.7 Plain lists in LaTeX export
 -----------------------------------
 
 The LaTeX export backend accepts the ‘environment’ and ‘options’
 attributes for plain lists.  Both attributes work together for
 customizing lists, as shown in the examples:
 
      #+LATEX_HEADER: \usepackage[inline]{enumitem}
      Some ways to say "Hello":
      #+ATTR_LATEX: :environment itemize*
      #+ATTR_LATEX: :options [label={}, itemjoin={,}, itemjoin*={, and}]
      - Hola
      - Bonjour
      - Guten Tag.
 
    Since LaTeX supports only four levels of nesting for lists, use an
 external package, such as ‘enumitem’ in LaTeX, for levels deeper than
 four:
 
      #+LATEX_HEADER: \usepackage{enumitem}
      #+LATEX_HEADER: \renewlist{itemize}{itemize}{9}
      #+LATEX_HEADER: \setlist[itemize]{label=$\circ$}

 13.10.8 Source blocks in LaTeX export
 -------------------------------------
 
 LaTeX export backend provides multiple ways to render src blocks in
 LaTeX, according to the value of ‘org-latex-src-block-backend’.  The
 default value ‘verbatim’ renders the src code verbatim, without any
 extra styling.  Alternative values allow more colorful styling, but
 require additional LaTeX (‘listings’, ‘minted’), system (‘minted’), or
 Emacs (‘engraved’) packages.  See the ‘org-latex-src-block-backend’
 docstring for more details.
 
    The LaTeX export backend can make source code blocks into floating
 objects through the attributes ‘:float’ and ‘:options’.  For ‘:float’:
 
 ‘t’
      Makes a source block float; by default floats any source block with
      a caption.
 
 ‘multicolumn’
      Spans the source block across multiple columns of a page.
 
 ‘nil’
      Avoids a ‘:float’ even if using a caption; useful for source code
      blocks that may not fit on a page.
 
      #+ATTR_LATEX: :float nil
      #+BEGIN_SRC emacs-lisp
        Lisp code that may not fit in a single page.
      #+END_SRC
 
    The LaTeX export backend passes string values in ‘:options’ to LaTeX
 packages for customization of that specific source block.  In the
 example below, the ‘:options’ are set for Engraved or Minted.  Minted is
 a source code highlighting LaTeX package with many configurable
 options(1).  Both Minted and Engraved are built on fvextra
 (https://www.ctan.org/pkg/fvextra), and so support many of the same
 options.
 
      #+ATTR_LATEX: :options mathescape
      #+BEGIN_SRC emacs-lisp
        (defun Fib (n) ; $n_i = n_{i-2} + n_{i-1}$
          (if (< n 2) n (+ (Fib (- n 1)) (Fib (- n 2)))))
      #+END_SRC
 
    To apply similar configuration options for all source blocks in a
 file, use the ‘org-latex-listings-options’,
 ‘org-latex-engraved-options’, and ‘org-latex-minted-options’ variables.
 
    ---------- Footnotes ----------
 
    (1) Minted uses an external Python package for code highlighting,
 which requires the flag ‘-shell-escape’ to be added to
 ‘org-latex-pdf-process’.

 13.10.9 Example blocks in LaTeX export
 --------------------------------------
 
 The LaTeX export backend wraps the contents of example blocks in a
 ‘verbatim’ environment.  To change this behavior to use another
 environment globally, specify an appropriate export filter (see *note
 Advanced Export Configuration::).  To change this behavior to use
 another environment for each block, use the ‘:environment’ parameter to
 specify a custom environment.
 
      #+ATTR_LATEX: :environment myverbatim
      #+BEGIN_EXAMPLE
        This sentence is false.
      #+END_EXAMPLE
 
 
 File: org.info,  Node: Special blocks in LaTeX export,  Next: Horizontal rules in LaTeX export,  Prev: Example blocks in LaTeX export,  Up: LaTeX Export
 
 13.10.10 Special blocks in LaTeX export
 ---------------------------------------
 
 For other special blocks in the Org file, the LaTeX export backend makes
 a special environment of the same name.  The backend also takes
 ‘:options’, if any, and appends as-is to that environment’s opening
 string.  For example:
 
      #+BEGIN_abstract
        We demonstrate how to solve the Syracuse problem.
      #+END_abstract
 
      #+ATTR_LATEX: :options [Proof of important theorem]
      #+BEGIN_proof
        ...
        Therefore, any even number greater than 2 is the sum of two primes.
      #+END_proof
 
 exports to
 
      \begin{abstract}
        We demonstrate how to solve the Syracuse problem.
      \end{abstract}
 
      \begin{proof}[Proof of important theorem]
        ...
        Therefore, any even number greater than 2 is the sum of two primes.
      \end{proof}
 
    If you need to insert a specific caption command, use ‘:caption’
 attribute.  It overrides standard ‘CAPTION’ value, if any.  For example:
 
      #+ATTR_LATEX: :caption \MyCaption{HeadingA}
      #+BEGIN_proof
        ...
      #+END_proof

 13.10.11 Horizontal rules in LaTeX export
 -----------------------------------------
 
 The LaTeX export backend converts horizontal rules by the specified
 ‘:width’ and ‘:thickness’ attributes.  For example:
 
      #+ATTR_LATEX: :width .6\textwidth :thickness 0.8pt
      -----
 
 
 File: org.info,  Node: Verse blocks in LaTeX export,  Next: Quote blocks in LaTeX export,  Prev: Horizontal rules in LaTeX export,  Up: LaTeX Export
 
 13.10.12 Verse blocks in LaTeX export
 -------------------------------------
 
 The LaTeX export backend accepts five attributes for verse blocks:
 ‘:lines’, ‘:center’, ‘:versewidth’, ‘:latexcode’ and ‘:literal’.  The
 three first require the external LaTeX package ‘verse.sty’, which is an
 extension of the standard LaTeX environment.
 
 ‘:lines’
      To add marginal verse numbering.  Its value is an integer, the
      sequence in which the verses should be numbered.
 ‘:center’
      With value ‘t’ all the verses on the page are optically centered (a
      typographic convention for poetry), taking as a reference the
      longest verse, which must be indicated by the attribute
      ‘:versewidth’.
 ‘:versewidth’
      Its value is a literal text string with the longest verse.
 ‘:latexcode’
      It accepts any arbitrary LaTeX code that can be included within a
      LaTeX ‘verse’ environment.
 ‘:literal’
      With value t, all blank lines are preserved and exported as
      ‘\vspace*{\baselineskip}’, including the blank lines before or
      after contents.  Note that without the ‘:literal’ attribute, one or
      more blank lines between stanzas are exported as a single blank
      line, and any blank lines before or after the content are removed,
      which is more consistent with the syntax of the LaTeX ‘verse’
      environment, and the one provided by the ‘verse’ package.  If the
      ‘verse’ package is loaded, the vertical spacing between all stanzas
      can be controlled by the global length ‘\stanzaskip’ (see
      <https://www.ctan.org/pkg/verse>).
 
    A complete example with Shakespeare’s first sonnet:
 
      #+ATTR_LATEX: :center t :latexcode \color{red} :lines 5
      #+ATTR_LATEX: :versewidth Feed’st thy light’s flame with self-substantial fuel,
      #+BEGIN_VERSE
      From fairest creatures we desire increase,
      That thereby beauty’s rose might never die,
      But as the riper should by time decease
      His tender heir might bear his memory
      But thou, contracted to thine own bright eyes,
      Feed’st thy light’s flame with self-substantial fuel,
      Making a famine where abundance lies,
      Thyself thy foe, to thy sweet self too cruel.
      Thou that art now the world’s fresh ornament,
      And only herald to the gaudy spring,
      Within thine own bud buriest thy content,
      And, tender churl, mak’st waste in niggardly.
      Pity the world, or else this glutton be,
      To eat the world’s due, by the grave and thee.
      #+END_VERSE
 
 
 File: org.info,  Node: Quote blocks in LaTeX export,  Prev: Verse blocks in LaTeX export,  Up: LaTeX Export
 
 13.10.13 Quote blocks in LaTeX export
 -------------------------------------
 
 The LaTeX export backend accepts two attributes for quote blocks:
 ‘:environment’, for an arbitrary quoting environment (the default value
 is that of ‘org-latex-default-quote-environment’: ‘"quote"’) and
 ‘:options’.  For example, to choose the environment ‘quotation’,
 included as an alternative to ‘quote’ in standard LaTeX classes:
 
      #+ATTR_LATEX: :environment quotation
      #+BEGIN_QUOTE
      some text...
      #+END_QUOTE
 
    To choose the ‘foreigndisplayquote’ environment, included in the
 LaTeX package ‘csquotes’, with the ‘german’ option, use this syntax:
 
      #+LATEX_HEADER:\usepackage[autostyle=true]{csquotes}
      #+ATTR_LATEX: :environment foreigndisplayquote :options {german}
      #+BEGIN_QUOTE
      some text in German...
      #+END_QUOTE
 
 which is exported to LaTeX as
 
      \begin{foreigndisplayquote}{german}
      some text in German...
      \end{foreigndisplayquote}

 13.11 Markdown Export
 =====================
 
 The Markdown export backend, “md”, converts an Org file to Markdown
 format, as defined at <https://daringfireball.net/projects/markdown/>.
 This is the original Markdown specification, developed by John Gruber
 and Aaron Swartz.
 
    Since “md” backend is built on top of the HTML backend (see *note
 HTML Export::), it converts every Org construct not defined in Markdown
 syntax, such as tables, to HTML.
 
    Do note that the original markdown syntax has differences with other
 commonly used Markdown flavors.  See
 <https://en.wikipedia.org/wiki/Markdown> for more details.
 
 Markdown export commands
 ------------------------
 
 ‘C-c C-e m m’ (‘org-md-export-to-markdown’)
      Export to a text file with Markdown syntax.  For ‘myfile.org’, Org
      exports to ‘myfile.md’, overwritten without warning.
 
 ‘C-c C-e m M’ (‘org-md-export-as-markdown’)
      Export to a temporary buffer.  Does not create a file.
 
 ‘C-c C-e m o’
      Export as a text file with Markdown syntax, then open it.
 
 Header and sectioning structure
 -------------------------------
 
 Based on ‘org-md-headline-style’, Markdown export can generate headlines
 of both _atx_ and _setext_ types.  _setext_ limits headline levels to
 two whereas _atx_ limits headline levels to six.  _mixed_ exports
 headline levels one and two in _setext_-style, and headline levels three
 through six as _atx_-style headlines.  Beyond these limits, the export
 backend converts headlines to lists.  To set a limit to a level before
 the absolute limit (see *note Export Settings::).

 13.12.1 Pre-requisites for ODT export
 -------------------------------------
 
 The ODT export backend relies on the zip program to create the final
 compressed ODT output.  Check if ‘zip’ is locally available and
 executable.  Without it, export cannot finish.
 
 
 File: org.info,  Node: ODT export commands,  Next: ODT specific export settings,  Prev: Pre-requisites for ODT export,  Up: OpenDocument Text Export
 
 13.12.2 ODT export commands
 ---------------------------
 
 ‘C-c C-e o o’ (‘org-odt-export-to-odt’)
      Export as OpenDocument Text file.
 
      If ‘org-odt-preferred-output-format’ is specified, the ODT export
      backend automatically converts the exported file to that format.
 
      For ‘myfile.org’, Org exports to ‘myfile.odt’, overwriting without
      warning.  The ODT export backend exports a region only if a region
      was active.
 
      If the selected region is a single tree, the ODT export backend
      makes the tree head the document title.  Incidentally, ‘C-c @’
      selects the current subtree.  If the tree head entry has, or
      inherits, an ‘EXPORT_FILE_NAME’ property, the ODT export backend
      uses that for file name.
 
 ‘C-c C-e o O’
      Export as an OpenDocument Text file and open the resulting file.
 
      If ‘org-export-odt-preferred-output-format’ is specified, open the
      converted file instead.  See *note Automatically exporting to other
      formats::.

 13.12.3 ODT specific export settings
 ------------------------------------
 
 The ODT export backend has several additional keywords for customizing
 ODT output.  Setting these keywords works similar to the general options
 (see *note Export Settings::).
 
 ‘DESCRIPTION’
      This is the document’s description, which the ODT export backend
      inserts as document metadata.  For long descriptions, use multiple
      lines, prefixed with ‘DESCRIPTION’.
 
 ‘KEYWORDS’
      The keywords for the document.  The ODT export backend inserts the
      description along with author name, keywords, and related file
      metadata as metadata in the output file.  Use multiple ‘KEYWORDS’
      if necessary.
 
 ‘ODT_STYLES_FILE’
      The ODT export backend uses the ‘org-odt-styles-file’ by default.
      See *note Applying custom styles:: for details.
 
 ‘SUBTITLE’
      The document subtitle.
 
 
 File: org.info,  Node: Extending ODT export,  Next: Applying custom styles,  Prev: ODT specific export settings,  Up: OpenDocument Text Export
 
 13.12.4 Extending ODT export
 ----------------------------
 
 The ODT export backend can produce documents in other formats besides
 ODT using a specialized ODT converter process.  Its common interface
 works with popular converters to produce formats such as ‘doc’, or
 convert a document from one format, say ‘csv’, to another format, say
 ‘xls’.
 
    Customize ‘org-odt-convert-process’ variable to point to ‘unoconv’,
 which is the ODT’s preferred converter.  Working installations of
 LibreOffice would already have ‘unoconv’ installed.  Alternatively,
 other converters may be substituted here.  See *note Configuring a
 document converter::.
 
 Automatically exporting to other formats
 ........................................
 
 If ODT format is just an intermediate step to get to other formats, such
 as ‘doc’, ‘docx’, ‘rtf’, or ‘pdf’, etc., then extend the ODT export
 backend to directly produce that format.  Specify the final format in
 the ‘org-odt-preferred-output-format’ variable.  This is one way to
 extend (see *note ODT export commands::).
 
 Converting between document formats
 ...................................
 
 The Org export backend is made to be inter-operable with a wide range of
 text document format converters.  Newer generation converters, such as
 LibreOffice and Pandoc, can handle hundreds of formats at once.  Org
 provides a consistent interaction with whatever converter is installed.
 Here are some generic commands:
 
 ‘M-x org-odt-convert’
      Convert an existing document from one format to another.  With a
      prefix argument, opens the newly produced file.
 
 
 File: org.info,  Node: Applying custom styles,  Next: Links in ODT export,  Prev: Extending ODT export,  Up: OpenDocument Text Export
 
 13.12.5 Applying custom styles
 ------------------------------
 
 The ODT export backend comes with many OpenDocument styles (see *note
 Working with OpenDocument style files::).  To expand or further
 customize these built-in style sheets, either edit the style sheets
 directly or generate them using an application such as LibreOffice.  The
 example here shows creating a style using LibreOffice.
 
 Applying custom styles: the easy way
 ....................................
 
   1. Create a sample ‘example.org’ file with settings as shown below,
      and export it to ODT format.
 
           #+OPTIONS: H:10 num:t
 
   2. Open the above ‘example.odt’ using LibreOffice.  Use the _Stylist_
      to locate the target styles, which typically have the “Org” prefix.
      Open one, modify, and save as either OpenDocument Text (ODT) or
      OpenDocument Template (OTT) file.
 
   3. Customize the variable ‘org-odt-styles-file’ and point it to the
      newly created file.  For additional configuration options, see
      *note Overriding factory styles: x-overriding-factory-styles.
 
      To apply an ODT style to a particular file, use the
      ‘ODT_STYLES_FILE’ keyword as shown in the example below:
 
           #+ODT_STYLES_FILE: "/path/to/example.ott"
 
      or
 
           #+ODT_STYLES_FILE: ("/path/to/file.ott" ("styles.xml" "image/hdr.png"))
 
 Using third-party styles and templates
 ......................................
 
 The ODT export backend relies on many templates and style names.  Using
 third-party styles and templates can lead to mismatches.  Templates
 derived from built-in ODT templates and styles seem to have fewer
 problems.

 13.12.6 Links in ODT export
 ---------------------------
 
 ODT exporter creates native cross-references for internal links.  It
 creates Internet-style links for all other links.
 
    A link with no description and pointing to a regular, un-itemized,
 outline heading is replaced with a cross-reference and section number of
 the heading.
 
    A ‘\ref{label}’-style reference to an image, table etc., is replaced
 with a cross-reference and sequence number of the labeled entity.  See
 *note Labels and captions in ODT export::.
 
 
 File: org.info,  Node: Tables in ODT export,  Next: Images in ODT export,  Prev: Links in ODT export,  Up: OpenDocument Text Export
 
 13.12.7 Tables in ODT export
 ----------------------------
 
 The ODT export backend handles native Org mode tables (see *note
 Tables::) and simple ‘table.el’ tables.  Complex ‘table.el’ tables
 having column or row spans are not supported.  Such tables are stripped
 from the exported document.
 
    By default, the ODT export backend exports a table with top and
 bottom frames and with ruled lines separating row and column groups (see
 *note Column Groups::).  All tables are typeset to occupy the same
 width.  The ODT export backend honors any table alignments and relative
 widths for columns (see *note Column Width and Alignment::).
 
    Note that the ODT export backend interprets column widths as weighted
 ratios, the default weight being 1.
 
    Specifying ‘:rel-width’ property on an ‘ATTR_ODT’ line controls the
 width of the table.  For example:
 
      #+ATTR_ODT: :rel-width 50
      | Area/Month    |   Jan |   Feb |   Mar |   Sum |
      |---------------+-------+-------+-------+-------|
      | /             |     < |       |       |     < |
      | <l13>         |  <r5> |  <r5> |  <r5> |  <r6> |
      | North America |     1 |    21 |   926 |   948 |
      | Middle East   |     6 |    75 |   844 |   925 |
      | Asia Pacific  |     9 |    27 |   790 |   826 |
      |---------------+-------+-------+-------+-------|
      | Sum           |    16 |   123 |  2560 |  2699 |
 
    On export, the above table takes 50% of text width area.  The
 exporter sizes the columns in the ratio: 13:5:5:5:6.  The first column
 is left-aligned and rest of the columns, right-aligned.  Vertical rules
 separate the header and the last column.  Horizontal rules separate the
 header and the last row.
 
    For even more customization, create custom table styles and associate
 them with a table using the ‘ATTR_ODT’ keyword.  See *note Customizing
 tables in ODT export::.

 13.12.8 Images in ODT export
 ----------------------------
 
 Embedding images
 ................
 
 The ODT export backend processes image links in Org files that do not
 have descriptions, such as these links ‘[[file:img.jpg]]’ or
 ‘[[./img.jpg]]’, as direct image insertions in the final output.  Either
 of these examples works:
 
      [[file:img.png]]
 
      [[./img.png]]
 
 Embedding clickable images
 ..........................
 
 For clickable images, provide a link whose description is another link
 to an image file.  For example, to embed an image ‘org-mode-unicorn.png’
 which when clicked jumps to <https://orgmode.org> website, do the
 following
 
      [[https://orgmode.org][./org-mode-unicorn.png]]
 
 Sizing and scaling of embedded images
 .....................................
 
 Control the size and scale of the embedded images with the ‘ATTR_ODT’
 attribute.
 
    The ODT export backend starts with establishing the size of the image
 in the final document.  The dimensions of this size are measured in
 centimeters.  The backend then queries the image file for its dimensions
 measured in pixels.  For this measurement, the backend relies on
 ImageMagick’s identify program or Emacs ‘create-image’ and ‘image-size’
 API.  ImageMagick is the preferred choice for large file sizes or
 frequent batch operations.  The backend then converts the pixel
 dimensions using ‘org-odt-pixels-per-inch’ into the familiar 72 dpi or
 96 dpi.  The default value for this is in ‘display-pixels-per-inch’,
 which can be tweaked for better results based on the capabilities of the
 output device.  Here are some common image scaling operations:
 
 Explicitly size the image
      To embed ‘img.png’ as a 10 cm x 10 cm image, do the following:
 
           #+ATTR_ODT: :width 10 :height 10
           [[./img.png]]
 
 Scale the image
      To embed ‘img.png’ at half its size, do the following:
 
           #+ATTR_ODT: :scale 0.5
           [[./img.png]]
 
 Scale the image to a specific width
      To embed ‘img.png’ with a width of 10 cm while retaining the
      original height:width ratio, do the following:
 
           #+ATTR_ODT: :width 10
           [[./img.png]]
 
 Scale the image to a specific height
      To embed ‘img.png’ with a height of 10 cm while retaining the
      original height:width ratio, do the following:
 
           #+ATTR_ODT: :height 10
           [[./img.png]]
 
 Anchoring of images
 ...................
 
 The ODT export backend can anchor images to ‘as-char’, ‘paragraph’, or
 ‘page’.  Set the preferred anchor using the ‘:anchor’ property of the
 ‘ATTR_ODT’ line.
 
    To create an image that is anchored to a page:
 
      #+ATTR_ODT: :anchor page
      [[./img.png]]

 13.12.9.1 LaTeX math snippets
 .............................
 
 LaTeX math snippets (see *note LaTeX fragments::) can be embedded in the
 ODT document in one of the following ways:
 
 MathML
      Add this line to the Org file.  This option is activated on a
      per-file basis.
 
           #+OPTIONS: tex:t
 
      With this option, LaTeX fragments are first converted into MathML
      fragments using an external LaTeX-to-MathML converter program.  The
      resulting MathML fragments are then embedded as an OpenDocument
      Formula in the exported document.
 
      You can specify the LaTeX-to-MathML converter by customizing the
      variables ‘org-latex-to-mathml-convert-command’ and
      ‘org-latex-to-mathml-jar-file’.
 
      If you prefer to use MathToWeb(1) as your converter, you can
      configure the above variables as shown below.
 
           (setq org-latex-to-mathml-convert-command
                 "java -jar %j -unicode -force -df %o %I"
                 org-latex-to-mathml-jar-file
                 "/path/to/mathtoweb.jar")
 
      or, to use LaTeX​ML(2) instead,
 
           (setq org-latex-to-mathml-convert-command
                 "latexmlmath %i --presentationmathml=%o")
 
      To quickly verify the reliability of the LaTeX-to-MathML converter,
      use the following commands:
 
      ‘M-x org-export-as-odf’
           Convert a LaTeX math snippet to an OpenDocument formula
           (‘.odf’) file.
 
      ‘M-x org-export-as-odf-and-open’
           Convert a LaTeX math snippet to an OpenDocument formula
           (‘.odf’) file and open the formula file with the
           system-registered application.
 
 PNG images
      Add this line to the Org file.  This option is activated on a
      per-file basis.
 
           #+OPTIONS: tex:dvipng
 
           #+OPTIONS: tex:dvisvgm
 
      or
 
           #+OPTIONS: tex:imagemagick
 
      Under this option, LaTeX fragments are processed into PNG or SVG
      images and the resulting images are embedded in the exported
      document.  This method requires dvipng program, dvisvgm or
      ImageMagick programs.

 13.12.9.2 MathML and OpenDocument formula files
 ...............................................
 
 When embedding LaTeX math snippets in ODT documents is not reliable,
 there is one more option to try.  Embed an equation by linking to its
 MathML (‘.mml’) source or its OpenDocument formula (‘.odf’) file as
 shown below:
 
      [[./equation.mml]]
 
 or
 
      [[./equation.odf]]

 13.12.10 Labels and captions in ODT export
 ------------------------------------------
 
 ODT format handles labeling and captioning of objects based on their
 types.  Inline images, tables, LaTeX fragments, and Math formulas are
 numbered and captioned separately.  Each object also gets a unique
 sequence number based on its order of first appearance in the Org file.
 Each category has its own sequence.  A caption is just a label applied
 to these objects.
 
      #+CAPTION: Bell curve
      #+NAME:   fig:SED-HR4049
      [[./img/a.png]]
 
    When rendered, it may show as follows in the exported document:
 
      Figure 2: Bell curve
 
    To modify the category component of the caption, customize the option
 ‘org-odt-category-map-alist’.  For example, to tag embedded images with
 the string “Illustration” instead of the default string “Figure”, use
 the following setting:
 
      (setq org-odt-category-map-alist
            '(("__Figure__" "Illustration" "value" "Figure" org-odt--enumerable-image-p)))
 
    With the above modification, the previous example changes to:
 
      Illustration 2: Bell curve

 13.12.11 Literal examples in ODT export
 ---------------------------------------
 
 The ODT export backend supports literal examples (see *note Literal
 Examples::) with full fontification.  Internally, the ODT export backend
 relies on ‘htmlfontify.el’ to generate the style definitions needed for
 fancy listings.  The auto-generated styles get ‘OrgSrc’ prefix and
 inherit colors from the faces used by Emacs Font Lock library for that
 source language.
 
    For custom fontification styles, customize the
 ‘org-odt-create-custom-styles-for-srcblocks’ option.
 
    To turn off fontification of literal examples, customize the
 ‘org-odt-fontify-srcblocks’ option.

 13.12.12 Advanced topics in ODT export
 --------------------------------------
 
 The ODT export backend has extensive features useful for power users and
 frequent uses of ODT formats.
 
 Configuring a document converter
 ................................
 
 The ODT export backend works with popular converters with little or no
 extra configuration.  See *note Extending ODT export::.  The following
 is for unsupported converters or tweaking existing defaults.
 
 Register the converter
      Add the name of the converter to the ‘org-odt-convert-processes’
      variable.  Note that it also requires how the converter is invoked
      on the command line.  See the variable’s docstring for details.
 
 Configure its capabilities
      Specify which formats the converter can handle by customizing the
      variable ‘org-odt-convert-capabilities’.  Use the entry for the
      default values in this variable for configuring the new converter.
      Also see its docstring for details.
 
 Choose the converter
      Select the newly added converter as the preferred one by
      customizing the option ‘org-odt-convert-process’.
 
 Working with OpenDocument style files
 .....................................
 
 This section explores the internals of the ODT exporter; the means by
 which it produces styled documents; the use of automatic and custom
 OpenDocument styles.
 
    The ODT exporter relies on two files for generating its output.
 These files are bundled with the distribution under the directory
 pointed to by the variable ‘org-odt-styles-dir’.  The two files are:
 
 ‘OrgOdtStyles.xml’ 
      This file contributes to the ‘styles.xml’ file of the final ODT
      document.  This file gets modified for the following purposes:
 
        1. To control outline numbering based on user settings;
 
        2. To add styles generated by ‘htmlfontify.el’ for fontification
           of code blocks.
 
 ‘OrgOdtContentTemplate.xml’ 
      This file contributes to the ‘content.xml’ file of the final ODT
      document.  The contents of the Org outline are inserted between the
      ‘<office:text>’ ... ‘</office:text>’ elements of this file.
 
      Apart from serving as a template file for the final ‘content.xml’,
      the file serves the following purposes:
 
        1. It contains automatic styles for formatting of tables which
           are referenced by the exporter;
 
        2. It contains ‘<text:sequence-decl>’ ... ‘</text:sequence-decl>’
           elements that control numbering of tables, images, equations,
           and similar entities.
 
    The following two variables control the location from where the ODT
 exporter picks up the custom styles and content template files.
 Customize these variables to override the factory styles used by the
 exporter.
 
 ‘org-odt-styles-file’
      The ODT export backend uses the file pointed to by this variable,
      such as ‘styles.xml’, for the final output.  It can take one of the
      following values:
 
      ‘FILE.xml’
           Use this file instead of the default ‘styles.xml’
 
      ‘FILE.odt’ or ‘FILE.ott’
           Use the ‘styles.xml’ contained in the specified OpenDocument
           Text or Template file
 
      ‘FILE.odt’ or ‘FILE.ott’ and a subset of included files
           Use the ‘styles.xml’ contained in the specified OpenDocument
           Text or Template file.  Additionally extract the specified
           member files and embed those within the final ODT document.
 
           Use this option if the ‘styles.xml’ file references additional
           files like header and footer images.
 
      ‘nil’
           Use the default ‘styles.xml’.
 
 ‘org-odt-content-template-file’
      Use this variable to specify the blank ‘content.xml’ used in the
      final output.
 
 Creating one-off styles
 .......................
 
 The ODT export backend can read embedded raw OpenDocument XML from the
 Org file.  Such direct formatting is useful for one-off instances.
 
 Embedding ODT tags as part of regular text
      Enclose OpenDocument syntax in ‘@@odt:...@@’ for inline markup.
      For example, to highlight a region of text do the following:
 
           @@odt:<text:span text:style-name="Highlight">This is highlighted
           text</text:span>@@.  But this is regular text.
 
      *Hint:* To see the above example in action, edit the ‘styles.xml’
      (see *note Factory styles: x-orgodtstyles-xml.) and add a custom
      _Highlight_ style as shown below:
 
           <style:style style:name="Highlight" style:family="text">
             <style:text-properties fo:background-color="#ff0000"/>
           </style:style>
 
 Embedding a one-line OpenDocument XML
      The ODT export backend can read one-liner options with ‘#+ODT:’ in
      the Org file.  For example, to force a page break:
 
           #+ODT: <text:p text:style-name="PageBreak"/>
 
      *Hint:* To see the above example in action, edit your ‘styles.xml’
      (see *note Factory styles: x-orgodtstyles-xml.) and add a custom
      ‘PageBreak’ style as shown below.
 
           <style:style style:name="PageBreak" style:family="paragraph"
                        style:parent-style-name="Text_20_body">
             <style:paragraph-properties fo:break-before="page"/>
           </style:style>
 
 Embedding a block of OpenDocument XML
      The ODT export backend can also read ODT export blocks for
      OpenDocument XML.  Such blocks use the ‘#+BEGIN_EXPORT odt’ ...
      ‘#+END_EXPORT’ constructs.
 
      For example, to create a one-off paragraph that uses bold text, do
      the following:
 
           #+BEGIN_EXPORT odt
             <text:p text:style-name="Text_20_body_20_bold">
             This paragraph is specially formatted and uses bold text.
             </text:p>
           #+END_EXPORT
 
 Customizing tables in ODT export
 ................................
 
 Override the default table format by specifying a custom table style
 with the ‘#+ATTR_ODT’ line.  For a discussion on default formatting of
 tables, see *note Tables in ODT export::.
 
    This feature closely mimics the way table templates are defined in
 the OpenDocument-v1.2 specification(1).
 
    For quick preview of this feature, install the settings below and
 export the table that follows:
 
      (setq org-export-odt-table-styles
            (append org-export-odt-table-styles
                    '(("TableWithHeaderRowAndColumn" "Custom"
                       ((use-first-row-styles . t)
                        (use-first-column-styles . t)))
                      ("TableWithFirstRowandLastRow" "Custom"
                       ((use-first-row-styles . t)
                        (use-last-row-styles . t))))))
 
      #+ATTR_ODT: :style TableWithHeaderRowAndColumn
      | Name  | Phone | Age |
      | Peter |  1234 |  17 |
      | Anna  |  4321 |  25 |
 
    The example above used ‘Custom’ template and installed two table
 styles ‘TableWithHeaderRowAndColumn’ and ‘TableWithFirstRowandLastRow’.
 *Important:* The OpenDocument styles needed for producing the above
 template were pre-defined.  They are available in the section marked
 ‘Custom Table Template’ in ‘OrgOdtContentTemplate.xml’ (see *note
 Factory styles: x-orgodtcontenttemplate-xml.).  For adding new
 templates, define new styles there.
 
    To use this feature proceed as follows:
 
   1. Create a table template(2).
 
      A table template is set of ‘table-cell’ and ‘paragraph’ styles for
      each of the following table cell categories:
 
         • Body
         • First column
         • Last column
         • First row
         • Last row
         • Even row
         • Odd row
         • Even column
         • Odd Column
 
      The names for the above styles must be chosen based on the name of
      the table template using a well-defined convention.
 
      The naming convention is better illustrated with an example.  For a
      table template with the name ‘Custom’, the needed style names are
      listed in the following table.
 
      Cell type      Cell style                     Paragraph style
      ----------------------------------------------------------------------------------
      Body           ‘CustomTableCell’              ‘CustomTableParagraph’
      First column   ‘CustomFirstColumnTableCell’   ‘CustomFirstColumnTableParagraph’
      Last column    ‘CustomLastColumnTableCell’    ‘CustomLastColumnTableParagraph’
      First row      ‘CustomFirstRowTableCell’      ‘CustomFirstRowTableParagraph’
      Last row       ‘CustomLastRowTableCell’       ‘CustomLastRowTableParagraph’
      Even row       ‘CustomEvenRowTableCell’       ‘CustomEvenRowTableParagraph’
      Odd row        ‘CustomOddRowTableCell’        ‘CustomOddRowTableParagraph’
      Even column    ‘CustomEvenColumnTableCell’    ‘CustomEvenColumnTableParagraph’
      Odd column     ‘CustomOddColumnTableCell’     ‘CustomOddColumnTableParagraph’
 
      To create a table template with the name ‘Custom’, define the above
      styles in the ‘<office:automatic-styles>’ ...
      ‘</office:automatic-styles>’ element of the content template file
      (see *note Factory styles: x-orgodtcontenttemplate-xml.).
 
   2. Define a table style(3).
 
      To define a table style, create an entry for the style in the
      variable ‘org-odt-table-styles’ and specify the following:
 
         • the name of the table template created in step (1),
         • the set of cell styles in that template that are to be
           activated.
 
      For example, the entry below defines two different table styles
      ‘TableWithHeaderRowAndColumn’ and ‘TableWithFirstRowandLastRow’
      based on the same template ‘Custom’.  The styles achieve their
      intended effect by selectively activating the individual cell
      styles in that template.
 
           (setq org-export-odt-table-styles
                 (append org-export-odt-table-styles
                         '(("TableWithHeaderRowAndColumn" "Custom"
                            ((use-first-row-styles . t)
                             (use-first-column-styles . t)))
                           ("TableWithFirstRowandLastRow" "Custom"
                            ((use-first-row-styles . t)
                             (use-last-row-styles . t))))))
 
   3. Associate a table with the table style.
 
      To do this, specify the table style created in step (2) as part of
      the ‘ATTR_ODT’ line as shown below.
 
           #+ATTR_ODT: :style TableWithHeaderRowAndColumn
           | Name  | Phone | Age |
           | Peter |  1234 |  17 |
           | Anna  |  4321 |  25 |
 
 Validating OpenDocument XML
 ...........................
 
 Sometimes ODT format files may not open due to ‘.odt’ file corruption.
 To verify if such a file is corrupt, validate it against the
 OpenDocument Relax NG Compact (RNC) syntax schema.  But first the ‘.odt’
 files have to be decompressed using ‘zip’.  Note that ‘.odt’ files are
 ZIP archives: *note (emacs)File Archives::.  The contents of ODT files
 are in XML.  For general help with validation—and schema-sensitive
 editing—of XML files: *note (nxml-mode)Introduction::.
 
    Customize ‘org-odt-schema-dir’ to point to a directory with
 OpenDocument RNC files and the needed schema-locating rules.  The ODT
 export backend takes care of updating the ‘rng-schema-locating-files’.

 ‘C-c C-e i t’ (‘org-texinfo-export-to-texinfo’)
      Export as a Texinfo file with ‘.texi’ extension.  For ‘myfile.org’,
      Org exports to ‘myfile.texi’, overwriting without warning.
 
 ‘C-c C-e i i’ (‘org-texinfo-export-to-info’)
      Export to Texinfo format first and then process it to make an Info
      file.  To generate other formats, such as DocBook, customize the
      ‘org-texinfo-info-process’ variable.
 
 
 File: org.info,  Node: Texinfo specific export settings,  Next: Texinfo file header,  Prev: Texinfo export commands,  Up: Texinfo Export
 
 13.14.2 Texinfo specific export settings
 ----------------------------------------
 
 The Texinfo export backend has several additional keywords for
 customizing Texinfo output.  Setting these keywords works similar to the
 general options (see *note Export Settings::).
 
 ‘SUBTITLE’
      The document subtitle.
 
 ‘SUBAUTHOR’
      Additional authors for the document.
 
 ‘TEXINFO_FILENAME’
      The Texinfo filename.
 
 ‘TEXINFO_CLASS’
      The default document class (‘org-texinfo-default-class’), which
      must be a member of ‘org-texinfo-classes’.
 
 ‘TEXINFO_HEADER’
      Arbitrary lines inserted at the end of the header.
 
 ‘TEXINFO_POST_HEADER’
      Arbitrary lines inserted after the end of the header.
 
 ‘TEXINFO_DIR_CATEGORY’
      The directory category of the document.  Defaults to ‘Misc’.
 
 ‘TEXINFO_DIR_NAME’
      The directory name of the document.  This is the short name under
      which the ‘m’ command will find your manual in the main Info
      directory.  It defaults to the base name of the Texinfo file.
 
      The full form of the Texinfo entry is ‘* DIRNAME: NODE.’ where
      ‘NODE’ is usually just ‘(FILENAME)’.  Normally this option only
      provides the ‘DIRNAME’ part, but if you need more control, it can
      also be the full entry (recognized by the presence of parentheses
      or a leading ~* ~).
 
 ‘TEXINFO_DIR_DESC’
      The directory description of the document.  Defaults to the title
      of the document.
 
 ‘TEXINFO_PRINTED_TITLE’
      The printed title of the document.
 
 
 File: org.info,  Node: Texinfo file header,  Next: Texinfo title and copyright page,  Prev: Texinfo specific export settings,  Up: Texinfo Export
 
 13.14.3 Texinfo file header
 ---------------------------
 
 After creating the header for a Texinfo file, the Texinfo backend
 automatically generates a name and destination path for the Info file.
 To override this default with a more sensible path and name, specify the
 ‘TEXINFO_FILENAME’ keyword.
 
    Along with the output’s file name, the Texinfo header also contains
 language details (see *note Export Settings::) and encoding system as
 set in the ‘org-texinfo-coding-system’ variable.  Insert
 ‘TEXINFO_HEADER’ keywords for each additional command in the header, for
 example:
 
      #+TEXINFO_HEADER: @synindex
 
    Instead of repeatedly installing the same set of commands, define a
 class in ‘org-texinfo-classes’ once, and then activate it in the
 document by setting the ‘TEXINFO_CLASS’ keyword to that class.
 
 
 File: org.info,  Node: Texinfo title and copyright page,  Next: Info directory file,  Prev: Texinfo file header,  Up: Texinfo Export
 
 13.14.4 Texinfo title and copyright page
 ----------------------------------------
 
 The default template for hard copy output has a title page with ‘TITLE’
 and ‘AUTHOR’ keywords (see *note Export Settings::).  To replace the
 regular title with something different for the printed version, use the
 ‘TEXINFO_PRINTED_TITLE’ and ‘SUBTITLE’ keywords.  Both expect raw
 Texinfo code for setting their values.
 
    If one ‘AUTHOR’ line is not sufficient, add multiple ‘SUBAUTHOR’
 keywords.  They have to be set in raw Texinfo code.
 
      #+AUTHOR: Jane Smith
      #+SUBAUTHOR: John Doe
      #+TEXINFO_PRINTED_TITLE: This Long Title@@inlinefmt{tex,@*} Is Broken in @TeX{}
 
    Copying material is defined in a dedicated headline with a non-‘nil’
 ‘COPYING’ property.  The backend inserts the contents within a
 ‘@copying’ command at the beginning of the document.  The heading itself
 does not appear in the structure of the document.
 
    Copyright information is printed on the back of the title page.
 
      * Legalese
        :PROPERTIES:
        :COPYING: t
        :END:
 
        This is a short example of a complete Texinfo file, version 1.0.

 13.14.5 Info directory file
 ---------------------------
 
 The end result of the Texinfo export process is the creation of an Info
 file.  This Info file’s metadata has variables for category, title, and
 description: ‘TEXINFO_DIR_CATEGORY’, ‘TEXINFO_DIR_NAME’, and
 ‘TEXINFO_DIR_DESC’ keywords that establish where in the Info hierarchy
 the file fits.
 
    Here is an example that writes to the Info directory file:

 13.14.6 Headings and sectioning structure
 -----------------------------------------
 
 The Texinfo export backend uses a pre-defined scheme to convert Org
 headlines to equivalent Texinfo structuring commands.  A scheme like
 this maps top-level headlines to numbered chapters tagged as ‘@chapter’
 and lower-level headlines to unnumbered chapters tagged as
 ‘@unnumbered’.  To override such mappings to introduce ‘@part’ or other
 Texinfo structuring commands, define a new class in
 ‘org-texinfo-classes’.  Activate the new class with the ‘TEXINFO_CLASS’
 keyword.  When no new class is defined and activated, the Texinfo export
 backend defaults to the ‘org-texinfo-default-class’.
 
    If an Org headline’s level has no associated Texinfo structuring
 command, or is below a certain threshold (see *note Export Settings::),
 then the Texinfo export backend makes it into a list item.
 
    The Texinfo export backend makes any headline with a non-‘nil’
 ‘APPENDIX’ property into an appendix.  This happens independent of the
 Org headline level or the ‘TEXINFO_CLASS’ keyword.
 
    The Texinfo export backend creates a menu entry after the Org
 headline for each regular sectioning structure.  To override this with a
 shorter menu entry, use the ‘ALT_TITLE’ property (see *note Table of
 Contents::).  Texinfo menu entries also have an option for a longer
 ‘DESCRIPTION’ property.  Here’s an example that uses both to override
 the default menu entry:
 
      * Controlling Screen Display
        :PROPERTIES:
        :ALT_TITLE: Display
        :DESCRIPTION: Controlling Screen Display
        :END:
 
    The text before the first headline belongs to the _Top_ node, i.e.,
 the node in which a reader enters an Info manual.  As such, it is
 expected not to appear in printed output generated from the ‘.texi’
 file.  See *note (texinfo)The Top Node::, for more information.

 13.14.7 Indices
 ---------------
 
 The Texinfo export backend recognizes these indexing keywords if used in
 the Org file: ‘CINDEX’, ‘FINDEX’, ‘KINDEX’, ‘PINDEX’, ‘TINDEX’ and
 ‘VINDEX’.  Write their value as verbatim Texinfo code; in particular,
 ‘{’, ‘}’ and ‘@’ characters need to be escaped with ‘@’ if they do not
 belong to a Texinfo command.
 
      #+CINDEX: Defining indexing entries
 
    For the backend to generate an index entry for a headline, set the
 ‘INDEX’ property to ‘cp’ or ‘vr’.  These abbreviations come from Texinfo
 that stand for concept index and variable index.  The Texinfo manual has
 abbreviations for all other kinds of indexes.  The backend exports the
 headline as an unnumbered chapter or section command, and then inserts
 the index after its contents.
 
      * Concept Index
        :PROPERTIES:
        :INDEX: cp
        :END:

 13.14.9 Plain lists in Texinfo export
 -------------------------------------
 
 The Texinfo export backend converts unordered and ordered lists in the
 Org file using the default command ‘@itemize’.
 
    Ordered lists are numbered when exported to Texinfo format.  Such
 numbering obeys any counter (see *note Plain Lists::) in the first item
 of the list.  The ‘:enum’ attribute also let you start the list at a
 specific number, or switch to a lettered list, as illustrated here:
 
      #+ATTR_TEXINFO: :enum A
      1. Alpha
      2. Bravo
      3. Charlie
 
    The Texinfo export backend by default converts description lists in
 the Org file using the default command ‘@table’, which results in a
 table with two columns.  To change this behavior, set ‘:table-type’
 attribute to either ‘ftable’ or ‘vtable’ value.  For more information,
 see *note (texinfo)Two-column Tables::.
 
    The Texinfo export backend by default also applies a text highlight
 based on the defaults stored in ‘org-texinfo-table-default-markup’.  To
 override the default highlight command, specify another one with the
 ‘:indic’ attribute.
 
    Org syntax is limited to one entry per list item.  Nevertheless, the
 Texinfo export backend can split that entry according to any text
 provided through the ‘:sep’ attribute.  Each part then becomes a new
 entry in the first column of the table.
 
    The following example illustrates all the attributes above:
 
      #+ATTR_TEXINFO: :table-type vtable :sep , :indic asis
      - foo, bar :: This is the common text for variables foo and bar.
 
 becomes
 
      @vtable @asis
      @item foo
      @itemx bar
      This is the common text for variables foo and bar.
      @end table
 
    The ‘:compact’ attribute is an alternative to the ‘:sep’ attribute,
 which allows writing each entry on its own line.  If this attribute is
 non-‘nil’ and an item in a description list has no body but is followed
 by another item, then the second item is transcoded to ‘@itemx’.  This
 example is transcoded to the same output as above.
 
      #+ATTR_TEXINFO: :table-type vtable :indic asis :compact t
      - foo ::
      - bar ::
        This is the common text for variables foo and bar.
 
    Support for this compact syntax can also be enabled for all lists in
 a file using the ‘compact-itemx’ export option, or globally using the
 variable ‘org-texinfo-compact-itemx’.
 
    The Texinfo export backend also supports two approaches to writing
 Texinfo definition commands (see *note (texinfo)Definition Commands::).
 One of them uses description lists and is described below, the other
 relies on special blocks (see *note Special blocks in Texinfo export::).
 
    Items in a description list in an Org file that begin with
 ‘Function:’ or certain other prefixes are converted using Texinfo
 definition commands.  This works even if other items in the same list do
 not have such a prefix; if necessary a single description list is
 converted using multiple tables (such as ‘@vtable’) and definition
 commands (such as ‘@defun’).
 
      - Function: org-texinfo-drawer drawer contents info ::
        Transcode a DRAWER element from Org to Texinfo.
 
 becomes
 
      @defun org-texinfo-drawer drawer contents info ::
        Transcode a DRAWER element from Org to Texinfo.
      @end defun
 
    The recognized prefixes are ‘Command:’, ‘Function:’, ‘Macro:’,
 ‘Special Form:’, ‘Variable:’ and ‘User Option:’.  These are the same
 prefixes that appear in the Info file for the respective definition
 commands.  For example a ‘Function:’ item in the Org file is converted
 to a ‘@defun’ command in the Texinfo file, which in turn is converted to
 a definition prefixed with ‘-- Function:’ in the Info file.
 
    As a special case the prefix ‘Key:’ is also recognized.  No Texinfo
 definition command exists for key bindings and the output in Info files
 also lacks the ‘Key:’ prefix.  Even so this special case is supported
 because it provides a convenient shorthand, as illustrated here:
 
      - Key: C-c C-c (do-something) ::
        This command does something.
 
      - User Option: do-something-somehow ::
        This option controls how exactly ~do-something~ does its thing.
 
 becomes
 
      @table @asis
      @item @kbd{C-c C-c} (@code{do-something})
      @kindex C-c C-c
      @findex do-something
      This command does something.
      @end table
 
      @defopt do-something-somehow
      This option controls how exactly @code{do-something} does its thing.
      @end defopt
 
 Command in parenthesis, as done above, is optional.

 13.14.10 Tables in Texinfo export
 ---------------------------------
 
 When exporting tables, the Texinfo export backend uses the widest cell
 width in each column.  To override this and instead specify as fractions
 of line length, use the ‘:columns’ attribute.  See example below.
 
      #+ATTR_TEXINFO: :columns .5 .5
      | a cell | another cell |

 13.14.11 Images in Texinfo export
 ---------------------------------
 
 Insert a file link to the image in the Org file, and the Texinfo export
 backend inserts the image.  These links must have the usual supported
 image extensions and no descriptions.  To scale the image, use ‘:width’
 and ‘:height’ attributes.  For alternate text, use ‘:alt’ and specify
 the text using Texinfo code, as shown in the example:
 
      #+ATTR_TEXINFO: :width 1in :alt Alternate @i{text}
      [[ridt.pdf]]

 13.14.12 Quotations in Texinfo export
 -------------------------------------
 
 You can write the text of a quotation within a quote block (see *note
 Paragraphs::).  You may also emphasize some text at the beginning of the
 quotation with the ‘:tag’ attribute.
 
      #+ATTR_TEXINFO: :tag Warning
      #+BEGIN_QUOTE
      Striking your thumb with a hammer may cause severe pain and discomfort.
      #+END_QUOTE
 
    To specify the author of the quotation, use the ‘:author’ attribute.
 
      #+ATTR_TEXINFO: :author King Arthur
      #+BEGIN_QUOTE
      The Lady of the Lake, her arm clad in the purest shimmering samite,
      held aloft Excalibur from the bosom of the water, signifying by divine
      providence that I, Arthur, was to carry Excalibur.  That is why I am
      your king.

 13.14.13 Key bindings in Texinfo export
 ---------------------------------------
 
 Org does not provide any markup for key bindings that corresponds to
 Texinfo’s ‘@kbd’ and ‘@key’ commands.  One way to deal with this is to
 fall back to code syntax.  ‘~C-x SPC~’, for example, is transcoded to
 ‘@code{C-x SPC}’.
 
    A better approach is to define and use an Org macro named ‘kbd’.  To
 make that easier the function ‘org-texinfo-kbd-macro’ is provided, which
 is intended to be used like this:
 
      #+macro: kbd (eval (org-texinfo-kbd-macro $1))
 
      Type {{{kbd(C-c SPC)}}}.
 
 which becomes
 
      Type @kbd{C-c @key{SPC}}.

 -----------------------------------------
 
 The Texinfo export backend supports two approaches to writing Texinfo
 definition commands.  One of them is described here, the other in *note
 Plain lists in Texinfo export::.
 
    The Texinfo export backend converts special blocks to commands with
 the same name.  It also adds any ‘:options’ attributes to the end of the
 command, as shown in this example:
 
      #+ATTR_TEXINFO: :options org-org-export-to-org ...
      #+BEGIN_defun
        A somewhat obsessive function name.
      #+END_defun
 
 becomes
 
      @defun org-org-export-to-org ...
        A somewhat obsessive function name.
      @end defun

 13.15 iCalendar Export
 ======================
 
 A large part of Org mode’s interoperability success is its ability to
 easily export to or import from external applications.  The iCalendar
 export backend takes calendar data from Org files and exports to the
 standard iCalendar format.
 
    By default, iCalendar export only includes headings that contain
 active timestamps or diary sexps(1).
 
    The iCalendar export backend can also incorporate TODO entries based
 on the configuration of the ‘org-icalendar-include-todo’ variable.  The
 backend exports plain timestamps as ‘VEVENT’, TODO items as ‘VTODO’, and
 also create events from deadlines that are in non-TODO items.
 
    The backend uses the deadlines and scheduling dates in Org TODO items
 for setting the start and due dates for the iCalendar TODO entry.
 Consult the ‘org-icalendar-use-deadline’, ‘org-icalendar-use-scheduled’,
 and ‘org-icalendar-todo-unscheduled-start’ variables for more details.
 
    For tags on the headline, the iCalendar export backend makes them
 into iCalendar categories.  To tweak the inheritance of tags and TODO
 states, configure the variable ‘org-icalendar-categories’.  To assign
 clock alarms based on time, configure the ‘org-icalendar-alarm-time’
 variable.
 
    The iCalendar format standard requires globally unique identifier—or
 UID—for each entry.  The iCalendar export backend creates UIDs during
 export.  To save a copy of the UID in the Org file set the variable
 ‘org-icalendar-store-UID’.  The backend looks for the ‘ID’ property of
 the entry for reusing the same UID for subsequent exports.
 
    Since a single Org entry can result in multiple iCalendar
 entries—timestamp, deadline, scheduled item, or TODO item—Org adds
 prefixes to the UID, depending on which part of the Org entry triggered
 the creation of the iCalendar entry.  Prefixing ensures UIDs remains
 unique, yet enable synchronization programs trace the connections.
 
 ‘C-c C-e c f’ (‘org-icalendar-export-to-ics’)
      Create iCalendar entries from the current Org buffer and store them
      in the same directory, using a file extension ‘.ics’.
 
 ‘C-c C-e c a’ (‘org-icalendar-export-agenda-files’)
      Create iCalendar entries from Org files in ‘org-agenda-files’ and
      store in a separate iCalendar file for each Org file.
 
 ‘C-c C-e c c’ (‘org-icalendar-combine-agenda-files’)
      Create a combined iCalendar file from Org files in
      ‘org-agenda-files’ and write it to
      ‘org-icalendar-combined-agenda-file’ file name.
 
    The iCalendar export backend includes ‘SUMMARY’, ‘DESCRIPTION’,
 ‘LOCATION’, ‘TIMEZONE’ and ‘CLASS’ properties from the Org entries when
 exporting.  To force the backend to inherit the ‘LOCATION’, ‘TIMEZONE’
 and ‘CLASS’ properties, configure the ‘org-use-property-inheritance’
 variable.
 
    ‘SUMMARY’, ‘LOCATION’, and ‘DESCRIPTION’ properties can define
 multi-line summary, location, or description using ‘<PROPERTY>+’ syntax
 (see *note Property Syntax::):
 
      * Meeting at location with multi-line address
      <2024-01-08 Mon 14:20-15:00>
      :PROPERTIES:
      :LOCATION:  Someplace
      :LOCATION+: Some Street 5
      :LOCATION+: 12345 Small Town
      :END:
 
    When Org entries do not have ‘SUMMARY’, ‘DESCRIPTION’, ‘LOCATION’ and
 ‘CLASS’ properties, the iCalendar export backend derives the summary
 from the headline, and derives the description from the body of the Org
 item.  The ‘org-icalendar-include-body’ variable limits the maximum
 number of characters of the content are turned into its description.
 
    The ‘TIMEZONE’ property can be used to specify a per-entry time zone,
 and is applied to any entry with timestamp information.  Time zones
 should be specified as per the IANA time zone database format, e.g.,
 ‘Asia/Almaty’.  Alternately, the property value can be ‘UTC’, to force
 UTC time for this entry only.
 
    The ‘CLASS’ property can be used to specify a per-entry visibility
 class or access restrictions, and is applied to any entry with class
 information.  The iCalendar standard defines three visibility classes:
 ‘PUBLIC’
      The entry is publicly visible (this is the default).
 ‘CONFIDENTIAL’
      Only a limited group of clients get access to the event.
 ‘PRIVATE’
      The entry can be retrieved only by its owner.
    The server should treat unknown class properties the same as
 ‘PRIVATE’.
 
    The exported iCalendar file can advise clients how often to check for
 updates.  This duration can be set globally with the ‘org-icalendar-ttl’
 variable, or on a per-document basis with the ‘ICAL-TTL’ keyword.  This
 option should be set using the iCalendar notation for time durations;
 consult the docstring of ‘org-icalendar-ttl’ for more details.
 
    Exporting to iCalendar format depends in large part on the
 capabilities of the destination application.  Some are more lenient than
 others.  Consult the Org mode FAQ for advice on specific applications.
 
    ---------- Footnotes ----------
 
    (1) Diary sexp events, except certain built-in types (see
 ‘icalendar-export-sexp-enumerate-all’), are exported up to
 ‘icalendar-export-sexp-enumeration-days’ into future.

 13.16 Other Built-in Backends
 =============================
 
 Other export backends included with Org are:
 
    • ‘ox-man.el’: Export to a man page.
 
    To activate such backends, either customize ‘org-export-backends’ or
 load directly with ‘(require 'ox-man)’.  On successful load, the backend
 adds new keys in the export dispatcher (see *note The Export
 Dispatcher::).
 
    Follow the comment section of such files, for example, ‘ox-man.el’,
 for usage and configuration details.

 13.17 Advanced Export Configuration
 ===================================
 
 Export hooks
 ------------
 
 The export process executes two hooks before the actual exporting
 begins.  The first hook, ‘org-export-before-processing-functions’, runs
 before any expansions of macros, Babel code, and include keywords in the
 buffer.  The second hook, ‘org-export-before-parsing-functions’, runs
 before the buffer is parsed.
 
    Functions added to these hooks are called with a single argument: the
 export backend actually used, as a symbol.  You may use them for heavy
 duty structural modifications of the document.  For example, you can
 remove every headline in the buffer during export like this:
 
      (defun my-headline-removal (backend)
        "Remove all headlines in the current buffer.
      BACKEND is the export backend being used, as a symbol."
        (org-map-entries
         (lambda ()
           (delete-region (point) (line-beginning-position 2))
           ;; We need to tell `org-map-entries' to not skip over heading at
           ;; point.  Otherwise, it would continue from _next_ heading.  See
           ;; the docstring of `org-map-entries' for details.
           (setq org-map-continue-from (point)))))
 
      (add-hook 'org-export-before-parsing-functions #'my-headline-removal)
 
 Filters
 -------
 
 Filters are lists of functions to be applied to certain parts for a
 given backend.  The output from the first function in the filter is
 passed on to the next function in the filter.  The final output is the
 output from the final function in the filter.
 
    The Org export process has many filter sets applicable to different
 types of objects, plain text, parse trees, export options, and final
 output formats.  The filters are named after the element type or object
 type: ‘org-export-filter-TYPE-functions’, where TYPE is the type
 targeted by the filter.  Valid types are:
 
 body                     bold                     babel-call
 center-block             clock                    code
 diary-sexp               drawer                   dynamic-block
 entity                   example-block            export-block
 export-snippet           final-output             fixed-width
 footnote-definition      footnote-reference       headline
 horizontal-rule          inline-babel-call        inline-src-block
 inlinetask               italic                   item
 keyword                  latex-environment        latex-fragment
 line-break               link                     node-property
 options                  paragraph                parse-tree
 plain-list               plain-text               planning
 property-drawer          quote-block              radio-target
 section                  special-block            src-block
 statistics-cookie        strike-through           subscript
 superscript              table                    table-cell
 table-row                target                   timestamp
 underline                verbatim                 verse-block
 
    Here is an example filter that replaces non-breaking spaces ~ ~ in
 the Org buffer with ‘~’ for the LaTeX backend.
 
      (defun my-latex-filter-nobreaks (text backend info)
        "Ensure \" \" are properly handled in LaTeX export."
        (when (org-export-derived-backend-p backend 'latex)
          (replace-regexp-in-string " " "~" text)))
 
      (add-to-list 'org-export-filter-plain-text-functions
                   'my-latex-filter-nobreaks)
 
    A filter requires three arguments: the code to be transformed, the
 name of the backend, and some optional information about the export
 process.  The third argument can be safely ignored.  Note the use of
 ‘org-export-derived-backend-p’ predicate that tests for _latex_ backend
 or any other backend, such as _beamer_, derived from _latex_.
 
 Defining filters for individual files
 -------------------------------------
 
 The Org export can filter not just for backends, but also for specific
 files through the ‘BIND’ keyword.  Here is an example with two filters;
 one removes brackets from time stamps, and the other removes
 strike-through text.  The filter functions are defined in a code block
 in the same Org file, which is a handy location for debugging.
 
      #+BIND: org-export-filter-timestamp-functions (tmp-f-timestamp)
      #+BIND: org-export-filter-strike-through-functions (tmp-f-strike-through)
      #+BEGIN_SRC emacs-lisp :exports results :results none
        (defun tmp-f-timestamp (s backend info)
          (replace-regexp-in-string "&[lg]t;\\|[][]" "" s))
        (defun tmp-f-strike-through (s backend info) "")
      #+END_SRC
 
 Summary of the export process
 -----------------------------
 
 Org mode export is a multi-step process that works on a temporary copy
 of the buffer.  The export process consists of 4 major steps:
 
   1. Process the temporary copy, making necessary changes to the buffer
      text;
 
   2. Parse the buffer, converting plain Org markup into an abstract
      syntax tree (AST);
 
   3. Convert the AST to text, as prescribed by the selected export
      backend;
 
   4. Post-process the resulting exported text.
 
 Process temporary copy of the source Org buffer (1):
 
   1. Execute ‘org-export-before-processing-functions’ (see *note Export
      hooks::);
 
   2. Expand ‘#+include’ keywords in the whole buffer (see *note Include
      Files::);
 
   3. Remove commented subtrees in the whole buffer (see *note Comment
      Lines::);
 
   4. Replace macros in the whole buffer (see *note Macro Replacement::);
 
   5. When ‘org-export-use-babel’ is non-nil (default), process code
      blocks:
 
         • Leave code blocks inside archived subtrees (see *note Internal
           archiving::) as is;
 
         • Evaluate all the other code blocks according to code block
           headers (see *note Limit code block evaluation::);
 
         • Remove code, results of evaluation, both, or neither according
           to ‘:exports’ header argument (see *note Exporting Code
           Blocks::).
 
 Parse the temporary buffer, creating AST:
 
   1. Execute ‘org-export-before-parsing-functions’ (see *note Export
      hooks::).  The hook functions may still modify the buffer;
 
   2. Calculate export option values according to subtree-specific export
      settings, in-buffer keywords, ‘#+BIND’ keywords, and buffer-local
      and global customization.  The whole buffer is considered;
 
   3. When ‘org-org-with-cite-processors’ is non-nil (default), determine
      contributing bibliographies and record them into export options
      (see *note Citations::).  The whole buffer is considered;
 
   4. Execute ‘org-export-filter-options-functions’;
 
   5. Parse the accessible portion of the temporary buffer to generate an
      AST.  The AST is a nested list of lists representing Org syntax
      elements (see Org Element API
      (https://orgmode.org/worg/dev/org-element-api.html) for more
      details):
 
           (org-data ...
            (heading
             (section
              (paragraph (plain-text) (bold (plain-text))))
             (heading)
             (heading (section ...))))
 
      Past this point, modifications to the temporary buffer no longer
      affect the export; Org export works only with the AST;
 
   6. Remove elements that are not exported from the AST:
 
         • Headings according to ‘SELECT_TAGS’ and ‘EXCLUDE_TAGS’ export
           keywords; ‘task’, ‘inline’, ‘arch’ export options (see *note
           Export Settings::);
 
         • Comments;
 
         • Clocks, drawers, fixed-width environments, footnotes, LaTeX
           environments and fragments, node properties, planning lines,
           property drawers, statistics cookies, timestamps, etc
           according to ‘#+OPTIONS’ keyword (see *note Export
           Settings::);
 
         • Table rows containing width and alignment markers, unless the
           selected export backend changes ‘:with-special-rows’ export
           option to non-nil (see *note Column Width and Alignment::);
 
         • Table columns containing recalc marks (see *note Advanced
           features::).
 
   7. Expand environment variables in file link AST nodes according to
      the ‘expand-links’ export option (see *note Export Settings::);
 
   8. Execute ‘org-export-filter-parse-tree-functions’.  These functions
      can modify the AST by side effects;
 
   9. When ‘org-org-with-cite-processors’ is non-nil (default), replace
      citation AST nodes and ‘#+print_bibliography’ keyword AST nodes as
      prescribed by the selected citation export processor (see *note
      Citation export processors::).
 
 Convert the AST to text by traversing the AST nodes, depth-first:
 
   1. Convert the leaf nodes (without children) to text as prescribed by
      “transcoders” in the selected export backend (2);
 
   2. Pass the converted nodes through the corresponding export filters
      (see *note Filters::);
 
   3. Concatenate all the converted child nodes to produce parent node
      contents;
 
   4. Convert the nodes with children to text, passing the nodes
      themselves and their exported contents to the corresponding
      transcoders and then to the export filters (see *note Filters::).
 
 Post-process the exported text:
 
   1. Post-process the converted AST, as prescribed by the export
      backend.  (3)  This step usually adds generated content (like Table
      of Contents) to the exported text;
 
   2. Execute ‘org-export-filter-body-functions’;
 
   3. Unless body-only export is selected (see *note The Export
      Dispatcher::), add the necessary metadata to the final document, as
      prescribed by the export backend.  Examples: Document author/title;
      HTML headers/footers; LaTeX preamble;
 
   4. When ‘org-org-with-cite-processors’ is non-nil (default), add
      bibliography metadata, as prescribed by the citation export
      processor;
 
   5. Execute ‘org-export-filter-final-output-functions’.
 
 Extending an existing backend
 -----------------------------
 
 Some parts of the conversion process can be extended for certain
 elements so as to introduce a new or revised translation.  That is how
 the HTML export backend was extended to handle Markdown format.  The
 extensions work seamlessly so any aspect of filtering not done by the
 extended backend is handled by the original backend.  Of all the export
 customization in Org, extending is very powerful as it operates at the
 parser level.
 
    For this example, make the _ascii_ backend display the language used
 in a source code block.  Also make it display only when some attribute
 is non-‘nil’, like the following:
 
      #+ATTR_ASCII: :language t
 
    Then extend ASCII backend with a custom “my-ascii” backend.
 
      (defun my-ascii-src-block (src-block contents info)
        "Transcode a SRC-BLOCK element from Org to ASCII.
      CONTENTS is nil.  INFO is a plist used as a communication
      channel."
        (if (not (org-export-read-attribute :attr_ascii src-block :language))
            (org-export-with-backend 'ascii src-block contents info)
          (concat
           (format ",--[ %s ]--\n%s`----"
                   (org-element-property :language src-block)
                   (replace-regexp-in-string
                    "^" "| "
                    (org-element-normalize-string
                     (org-export-format-code-default src-block info)))))))
 
      (org-export-define-derived-backend 'my-ascii 'ascii
        :translate-alist '((src-block . my-ascii-src-block)))
 
    The ‘my-ascii-src-block’ function looks at the attribute above the
 current element.  If not true, hands over to _ascii_ backend.  If true,
 which it is in this example, it creates a box around the code and leaves
 room for the inserting a string for language.  The last form creates the
 new backend that springs to action only when translating ‘src-block’
 type elements.
 
    To use the newly defined backend, evaluate the following from an Org
 buffer:
 
      (org-export-to-buffer 'my-ascii "*Org MY-ASCII Export*")
 
    Further steps to consider would be an interactive function,
 self-installing an item in the export dispatcher menu, and other
 user-friendly improvements.  See
 <https://orgmode.org/worg/dev/org-export-reference.html> for more
 details.
 
    ---------- Footnotes ----------
 
    (1) Unless otherwise specified, each step of the export process only
 operates on the accessible portion of the buffer.  When subtree export
 is selected (see *note The Export Dispatcher::), the buffer is narrowed
 to the body of the selected subtree, so that the rest of the buffer
 text, except export keywords, does not contribute to the export output.

 ‘org-export-define-backend’ and ‘org-export-define-derived-backend’.

 13.18 Export Region
 ===================
 
 Some export backends include commands to convert a region of Org
 formatted text to another format, such as HTML or LaTeX.  The conversion
 replaces the original source.  Here are such commands:
 
 ‘org-export-region-to-ascii’
      Convert the selected region into ASCII.
 
 ‘org-export-region-to-utf8’
      Convert the selected region into UTF-8.
 
 ‘org-export-region-to-html’
      Convert the selected region into HTML.
 
 ‘org-export-region-to-latex’
      Convert the selected region into LaTeX.
 
 ‘org-export-region-to-texinfo’
      Convert the selected region into Texinfo.
 
 ‘org-export-region-to-md’
      Convert the selected region into Markdown.
 
    The in-place conversion is particularly handy for quick conversion of
 tables and lists in non-Org buffers.  For example, in an HTML buffer,
 write a list in Org syntax, select it, and convert it to HTML with ‘M-x
 org-html-convert-region-to-html’.

 14 Publishing
 *************
 
 Org includes a publishing management system that allows you to configure
 automatic HTML conversion of _projects_ composed of interlinked Org
 files.  You can also configure Org to automatically upload your exported
 HTML pages and related attachments, such as images and source code
 files, to a web server.
 
    You can also use Org to convert files into PDF, or even combine HTML
 and PDF conversion so that files are available in both formats on the
 server.
 
    Publishing has been contributed to Org by David O’Toole.

 File: org.info,  Node: Project alist,  Next: Sources and destinations,  Up: Configuration
 
 14.1.1 The variable ‘org-publish-project-alist’
 -----------------------------------------------
 
 Publishing is configured almost entirely through setting the value of
 one variable, called ‘org-publish-project-alist’.  Each element of the
 list configures one project, and may be in one of the two following
 forms:
 
      ("project-name" :property value :property value ...)
 
 i.e., a well-formed property list with alternating keys and values, or:
 
      ("project-name" :components ("project-name" "project-name" ...))
 
    In both cases, projects are configured by specifying property values.
 A project defines the set of files that are to be published, as well as
 the publishing configuration to use when publishing those files.  When a
 project takes the second form listed above, the individual members of
 the ‘:components’ property are taken to be sub-projects, which group
 together files requiring different publishing options.  When you publish
 such a “meta-project”, all the components are also published, in the
 sequence given.
 
 
 File: org.info,  Node: Sources and destinations,  Next: Selecting files,  Prev: Project alist,  Up: Configuration
 
 14.1.2 Sources and destinations for files
 -----------------------------------------
 
 Most properties are optional, but some should always be set.  In
 particular, Org needs to know where to look for source files, and where
 to put published files.
 
 ‘:base-directory’
      Directory containing publishing source files.
 
 ‘:publishing-directory’
      Directory where output files are published.  You can directly
      publish to a webserver using a file name syntax appropriate for the
      Emacs tramp package.  Or you can publish to a local directory and
      use external tools to upload your website (see *note Uploading
      Files::).
 
 ‘:preparation-function’
      Function or list of functions to be called before starting the
      publishing process, for example, to run ‘make’ for updating files
      to be published.  Each preparation function is called with a single
      argument, the project property list.
 
 ‘:completion-function’
      Function or list of functions called after finishing the publishing
      process, for example, to change permissions of the resulting files.
      Each completion function is called with a single argument, the
      project property list.
 
 
 File: org.info,  Node: Selecting files,  Next: Publishing action,  Prev: Sources and destinations,  Up: Configuration
 
 14.1.3 Selecting files
 ----------------------
 
 By default, all files with extension ‘.org’ in the base directory are
 considered part of the project.  This can be modified by setting the
 following properties
 
 ‘:base-extension’
      Extension—without the dot—of source files.  This actually is a
      regular expression.  Set this to the symbol ‘any’ if you want to
      get all files in ‘:base-directory’, even without extension.
 
 ‘:exclude’
      Regular expression to match file names that should not be
      published, even though they have been selected on the basis of
      their extension.
 
 ‘:include’
      List of files to be included regardless of ‘:base-extension’ and
      ‘:exclude’.
 
 ‘:recursive’
      Non-‘nil’ means, check base-directory recursively for files to
      publish.
 
 
 File: org.info,  Node: Publishing action,  Next: Publishing options,  Prev: Selecting files,  Up: Configuration
 
 14.1.4 Publishing action
 ------------------------
 
 Publishing means that a file is copied to the destination directory and
 possibly transformed in the process.  The default transformation is to
 export Org files as HTML files, and this is done by the function
 ‘org-html-publish-to-html’ which calls the HTML exporter (see *note HTML
 Export::).  But you can also publish your content as PDF files using
 ‘org-latex-publish-to-pdf’, or as ASCII, Texinfo, etc., using the
 corresponding functions.
 
    If you want to publish the Org file as an ‘.org’ file but with
 _archived_, _commented_, and _tag-excluded_ trees removed, use
 ‘org-org-publish-to-org’.  This produces ‘file.org’ and puts it in the
 publishing directory.  If you want a htmlized version of this file, set
 the parameter ‘:htmlized-source’ to ‘t’.  It produces ‘file.org.html’ in
 the publishing directory(1).
 
    Other files like images only need to be copied to the publishing
 destination; for this you can use ‘org-publish-attachment’.  For non-Org
 files, you always need to specify the publishing function:
 
 ‘:publishing-function’
      Function executing the publication of a file.  This may also be a
      list of functions, which are all called in turn.
 
 ‘:htmlized-source’
      Non-‘nil’ means, publish htmlized source.
 
    The function must accept three arguments: a property list containing
 at least a ‘:publishing-directory’ property, the name of the file to be
 published, and the path to the publishing directory of the output file.
 It should take the specified file, make the necessary transformation, if
 any, and place the result into the destination folder.
 
    ---------- Footnotes ----------
 
    (1) If the publishing directory is the same as the source directory,
 ‘file.org’ is exported as ‘file.org.org’, so you probably do not want to
 do this.
 
 
 File: org.info,  Node: Publishing options,  Next: Publishing links,  Prev: Publishing action,  Up: Configuration
 
 14.1.5 Options for the exporters
 --------------------------------
 
 The property list can be used to set many export options for the HTML
 and LaTeX exporters.  In most cases, these properties correspond to user
 variables in Org.  The table below lists these properties along with the
 variable they belong to.  See the documentation string for the
 respective variable for details.
 
    When a property is given a value in ‘org-publish-project-alist’, its
 setting overrides the value of the corresponding user variable, if any,
 during publishing.  Options set within a file (see *note Export
 Settings::), however, override everything.

 File: org.info,  Node: Publishing links,  Next: Site map,  Prev: Publishing options,  Up: Configuration
 
 14.1.6 Publishing links
 -----------------------
 
 To create a link from one Org file to another, you would use something
 like ‘[[file:foo.org][The foo]]’ or simply ‘[[file:foo.org]]’ (see *note
 External Links::).  When published, this link becomes a link to
 ‘foo.html’.  You can thus interlink the pages of your “Org web” project
 and the links will work as expected when you publish them to HTML.  If
 you also publish the Org source file and want to link to it, use an
 ‘http’ link instead of a ‘file:’ link, because ‘file’ links are
 converted to link to the corresponding ‘.html’ file.
 
    Links to encrypted Org files, like ‘[[file:foo.org.gpg]]’ are also
 supported.
 
    You may also link to related files, such as images.  Provided you are
 careful with relative file names, and provided you have also configured
 Org to upload the related files, these links will work too.  See *note
 Complex example::, for an example of this usage.
 
    Links between published documents can contain some search options
 (see *note Search Options::), which will be resolved to the appropriate
 location in the linked file.  For example, once published to HTML, the
 following links all point to a dedicated anchor in ‘foo.html’.
 
      [[file:foo.org::*heading]]
      [[file:foo.org::#custom-id]]
      [[file:foo.org::target]]
 
 
 File: org.info,  Node: Site map,  Next: Generating an index,  Prev: Publishing links,  Up: Configuration
 
 14.1.7 Generating a sitemap
 ---------------------------
 
 The following properties may be used to control publishing of a map of
 files for a given project.
 
 ‘:auto-sitemap’
      When non-‘nil’, publish a sitemap during
      ‘org-publish-current-project’ or ‘org-publish-all’.
 
 ‘:sitemap-filename’
      Filename for output of sitemap.  Defaults to ‘sitemap.org’, which
      becomes ‘sitemap.html’.
 
 ‘:sitemap-title’
      Title of sitemap page.  Defaults to name of file.
 
 ‘:sitemap-style’
      Can be ‘list’ (site-map is just an itemized list of the titles of
      the files involved) or ‘tree’ (the directory structure of the
      source files is reflected in the site-map).  Defaults to ‘tree’.
 
 ‘:sitemap-format-entry’
      With this option one can tell how a site-map entry is formatted in
      the site-map.  It is a function called with three arguments: the
      file or directory name relative to base directory of the project,
      the site-map style and the current project.  It is expected to
      return a string.  Default value turns file names into links and use
      document titles as descriptions.  For specific formatting needs,
      one can use ‘org-publish-find-date’, ‘org-publish-find-title’ and
      ‘org-publish-find-property’, to retrieve additional information
      about published documents.
 
 ‘:sitemap-function’
      Plug-in function to use for generation of the sitemap.  It is
      called with two arguments: the title of the site-map and a
      representation of the files and directories involved in the project
      as a nested list, which can further be transformed using
      ‘org-list-to-generic’, ‘org-list-to-subtree’ and alike.  Default
      value generates a plain list of links to all files in the project.
 
 ‘:sitemap-sort-folders’
      Where folders should appear in the sitemap.  Set this to ‘first’
      (default) or ‘last’ to display folders first or last, respectively.
      When set to ‘ignore’, folders are ignored altogether.  Any other
      value mixes files and folders.  This variable has no effect when
      site-map style is ‘tree’.
 
 ‘:sitemap-sort-files’
      How the files are sorted in the site map.  Set this to
      ‘alphabetically’ (default), ‘chronologically’ or
      ‘anti-chronologically’.  ‘chronologically’ sorts the files with
      older date first while ‘anti-chronologically’ sorts the files with
      newer date first.  ‘alphabetically’ sorts the files alphabetically.
      The date of a file is retrieved with ‘org-publish-find-date’.
 
 ‘:sitemap-ignore-case’
      Should sorting be case-sensitive?  Default ‘nil’.
 
 
 File: org.info,  Node: Generating an index,  Prev: Site map,  Up: Configuration
 
 14.1.8 Generating an index
 --------------------------
 
 Org mode can generate an index across the files of a publishing project.
 
 ‘:makeindex’
      When non-‘nil’, generate in index in the file ‘theindex.org’ and
      publish it as ‘theindex.html’.
 
    The file is created when first publishing a project with the
 ‘:makeindex’ set.  The file only contains a statement ‘#+INCLUDE:
 "theindex.inc"’.  You can then build around this include statement by
 adding a title, style information, etc.
 
    Index entries are specified with ‘INDEX’ keyword.  An entry that
 contains an exclamation mark creates a sub item.

 14.2 Uploading Files
 ====================
 
 For those people already utilizing third party sync tools such as Rsync
 or Unison, it might be preferable not to use the built-in remote
 publishing facilities of Org mode which rely heavily on Tramp.  Tramp,
 while very useful and powerful, tends not to be so efficient for
 multiple file transfer and has been known to cause problems under heavy
 usage.
 
    Specialized synchronization utilities offer several advantages.  In
 addition to timestamp comparison, they also do content and
 permissions/attribute checks.  For this reason you might prefer to
 publish your web to a local directory—possibly even _in place_ with your
 Org files—and then use Unison or Rsync to do the synchronization with
 the remote host.
 
    Since Unison, for example, can be configured as to which files to
 transfer to a certain remote destination, it can greatly simplify the
 project publishing definition.  Simply keep all files in the correct
 location, process your Org files with ‘org-publish’ and let the
 synchronization tool do the rest.  You do not need, in this scenario, to
 include attachments such as JPG, CSS or PNG files in the project
 definition since the third-party tool syncs them.
 
    Publishing to a local directory is also much faster than to a remote
 one, so that you can afford more easily to republish entire projects.
 If you set ‘org-publish-use-timestamps-flag’ to ‘nil’, you gain the main
 benefit of re-including any changed external files such as source
 example files you might include with ‘INCLUDE’ keyword.  The timestamp
 mechanism in Org is not smart enough to detect if included files have
 been modified.

 14.3 Sample Configuration
 =========================
 
 Below we provide two example configurations.  The first one is a simple
 project publishing only a set of Org files.  The second example is more
 complex, with a multi-component project.
 
 * Menu:
 
 * Simple example::               One-component publishing.
 * Complex example::              A multi-component publishing example.

 14.3.1 Example: simple publishing configuration
 -----------------------------------------------
 
 This example publishes a set of Org files to the ‘public_html’ directory
 on the local machine.
 
      (setq org-publish-project-alist
            '(("org"
               :base-directory "~/org/"
               :publishing-function org-html-publish-to-html
               :publishing-directory "~/public_html"
               :section-numbers nil
               :with-toc nil
               :html-head "<link rel=\"stylesheet\"
                          href=\"../other/mystyle.css\"
                          type=\"text/css\"/>")))

 14.3.2 Example: complex publishing configuration
 ------------------------------------------------
 
 This more complicated example publishes an entire website, including Org
 files converted to HTML, image files, Emacs Lisp source code, and style
 sheets.  The publishing directory is remote and private files are
 excluded.
 
    To ensure that links are preserved, care should be taken to replicate
 your directory structure on the web server, and to use relative file
 paths.  For example, if your Org files are kept in ‘~/org/’ and your
 publishable images in ‘~/images/’, you would link to an image with
 
      file:../images/myimage.png
 
    On the web server, the relative path to the image should be the same.
 You can accomplish this by setting up an ‘images/’ folder in the right

 14.4 Triggering Publication
 ===========================
 
 Once properly configured, Org can publish with the following commands:
 
 ‘C-c C-e P x’ (‘org-publish’)
      Prompt for a specific project and publish all files that belong to
      it.
 
 ‘C-c C-e P p’ (‘org-publish-current-project’)
      Publish the project containing the current file.
 
 ‘C-c C-e P f’ (‘org-publish-current-file’)
      Publish only the current file.
 
 ‘C-c C-e P a’ (‘org-publish-all’)
      Publish every project.
 
    Org uses timestamps to track when a file has changed.  The above
 functions normally only publish changed files.  You can override this
 and force publishing of all files by giving a prefix argument to any of
 the commands above, or by customizing the variable
 ‘org-publish-use-timestamps-flag’.  This may be necessary in particular
 if files include other files via ‘SETUPFILE’ or ‘INCLUDE’ keywords.

 15 Citation handling
 ********************
 
 While links (see *note Hyperlinks::) are often sufficient to refer to
 external or internal information from Org, they have their limitations
 when referring to multiple targets or typesetting printed publications.
 
    Org mode provides a more sophisticated markup to “cite” external
 resources.  For example, consider the following Org mode snippet
 
      #+bibliography: citationdata.bib
 
      Org mode is used by various communities [cite:teaching: @orgteaching;
      and TeX: @orgtex].  [cite/author/caps:@orgtex] uses Org mode to simplify
      writing scientific publications, while [cite/author/caps:@orgteaching]
      experiment with Org babel to improve teaching.
 
      #+print_bibliography:
 
    Org mode will gather citation metadata from the ‘#+bibliography’
 database and use it to typeset the exported document in arbitrary
 formats.  For example, the snippet below shows ASCII export output.
 
      Org mode is used by various communities (teaching: Birkenkrahe, Marcus,
      2023, and TeX: Somma, Emmanuele F, 2023).  Somma, Emmanuele F uses Org
      mode to simplify writing scientific publications, while Birkenkrahe,
      Marcus experiment with Org babel to improve teaching.

      Programming Tools/, MDPI.
 
      Somma, Emmanuele F (2023). /Simplifying LaTeX with ORG-mode in Emacs/,
      TUGboat volume.
 
    In addition to export, users can use completion to search and insert
 citations from the bibliography (via ‘org-cite-insert’).  Citations also
 act like ordinary links, jumping to the citation metadata when
 “following” them using ‘org-open-at-point’.
 
    You can customize every aspect (_capability_) of citation handling
 using built-in or external _citation processors_.
 
    Org mode ships with several built-in citation processors tailored to
 work with LaTeX export and BibTeX bibliographies (‘bibtex’, ‘biblatex’,
 and ‘natbib’ processors), or with more generic formats described using
 Citation Style Language (https://citationstyles.org/) (‘csl’ processor).
 The default citation processor is ‘basic’ - it works with arbitrary
 export formats and recognizes both BibTeX and CSL bibliographies.  More
 citation processors are distributed as Emacs packages.
 
    Multiple citation processors can be mixed to meet your preferences.
 Configure ‘org-cite-activate-processor’, ‘org-cite-follow-processor’,
 ‘org-cite-insert-processor’, and ‘org-cite-export-processors’ to select
 which processor to use for every citation capability:
 
 activate
      Fontification, tooltip preview, etc.
 follow
      At-point actions on citations via ‘org-open-at-point’.
 insert
      Add and edit citations via ‘org-cite-insert’.
 export
      Via different libraries for different target formats.

 15.1 Citations
 ==============
 
 Before adding citations, first set one-or-more bibliographies, either
 globally with ‘org-cite-global-bibliography’, or locally using one or
 more “bibliography” keywords.
 
      #+bibliography: SomeFile.bib
      #+bibliography: /some/other/file.json
      #+bibliography: "/some/file/with spaces/in its name.bib"
 
    Org mode uses all the local and global bibliographies combined to
 search for citation keys.
 
    One can then insert and edit citations using ‘org-cite-insert’,
 called with ‘C-c C-x @’.
 
    A _citation_ requires one or more citation _key(s)_, elements
 identifying a reference in the bibliography.
 
    • Each citation is surrounded by brackets and uses the ‘cite’ type.
 
    • Each key starts with the character ‘@’.
 
           [cite:@key]
 
    • Each key can be qualified by a _prefix_ (e.g. “see ”) and/or a
      _suffix_ (e.g. “p. 123”), giving information useful or necessary
      for the comprehension of the citation but not included in the
      reference.
 
           [cite:see @key p. 123]
 
    • A single citation can cite more than one reference ; the keys are
      separated by semicolons ; the formatting of such citation groups is
      specified by the style.
 
           [cite:@key1;@key2;@key3]
 
    • One can also specify a stylistic variation for the citations by
      inserting a ‘/’ and a style name between the ‘cite’ keyword and the
      colon; this usually makes sense only for the author-year styles.
 
           [cite/style:common prefix ;prefix @key suffix; ... ; common suffix]
 
      When ‘style’ is not specified, one of the two default styles are
      used
 
         • either the default style specified in the ‘CITE_EXPORT’
           keyword (see *note Citation export processors::)
 
                #+cite_export: basic numeric noauthor/bare
                [cite:@key] is the same as [cite/noauthor/bare:@key]
 
         • or, if ‘CITE_EXPORT’ is not set, using the default ‘nil’ style
 
                [cite:@key] is the same as [cite/nil:@key]
 
    The only mandatory elements are:
 
    • The ‘cite’ keyword and the colon.
    • The ‘@’ character immediately preceding each key.
    • The brackets surrounding the citation(s) (group).

 15.2 Citation export processors
 ===============================
 
 Org currently includes the following export processors:
 
    • Two processors can export to a variety of formats, including
      ‘latex’ (and therefore ‘pdf’), ‘html’, ‘odt’ and plain (UTF8) text:
 
      basic
           a basic export processor, well adapted to situations where
           backward compatibility is not a requirement and formatting
           needs are minimal;
 
      csl
           this export processor uses format files written in Citation
           Style Language
           (https://en.wikipedia.org/wiki/Citation_Style_Language) via
           citeproc-el (https://github.com/andras-simonyi/citeproc-el);
 
    • In contrast, three other processors target LaTeX and LaTeX-derived
      formats exclusively:
 
      bibtex
           this export processor uses BibTeX, the historical
           bibliographic processor used with LaTeX, thus allowing the use
           of data and style files compatible with this processor
           (including a large number of publishers’ styles).  It only
           supports LaTeX’s ‘\cite’ and ‘\nocite’ commands.
 
      natbib
           as with the bibtex processor, but using the LaTeX package
           ‘natbib’, allowing more stylistic variants that LaTeX’s
           ‘\cite’ command.
 
      biblatex
           this backend allows the use of data and formats prepared for
           BibLaTeX, an alternate bibliographic processor used with
           LaTeX, which overcomes some serious BibTeX limitations, but
           has not (yet?) been widely adopted by publishers.
 
    The ‘CITE_EXPORT’ keyword specifies the export processor, citation
 style, and bibliography style; for example (all arguments are optional)
 
      #+cite_export: [export processor name] [bibliography style] [default citation style]
      #+cite_export: basic author-year author
 
 specifies the ‘basic’ export processor with citations inserted as
 author’s name and references indexed by author’s names and year;
 
      #+cite_export: csl /some/path/to/vancouver-brackets.csl
 
 specifies the ‘csl’ processor and CSL style, which in this case defines
 numeric citations and numeric references according to the ‘Vancouver’
 specification (as style used in many medical journals), following a
 typesetting variation putting citations between brackets;
 
      #+cite_export: natbib kluwer
 
 specifies the ‘natbib’ export processor with a label citation style
 conformant to the Harvard style and the specification of the
 Wolkers-Kluwer publisher; since it relies on the ‘bibtex’ processor of
 your LaTeX installation, it won’t export to anything but PDF.
 
      #+cite_export: biblatex numeric,backend=bibtex
 
 specifies the ‘biblatex’ export processor with the default ‘numeric’
 style and the ‘bibtex’ backend.  Always define the style first and then
 the rest of load-time options for the ‘biblatex’ package.
 Alternatively, you can use the ‘key=val,key=val’ format for the options
 as documented in the ‘biblatex’ package documentation:
 
      #+cite_export: biblatex backend=bibtex,style=numeric
 
    The ‘org-cite-biblatex-options’ variable in your Emacs configuration
 uses this format.  It will only export to PDF, since it relies on the
 ‘biblatex’ processor of your LaTeX installation.

 15.3 Bibliography printing
 ==========================
 
 The ‘PRINT_BIBLIOGRAPHY’ keyword specifies where the bibliography should
 be printed (note the colon):
 
      #+print_bibliography:
 
    The bibliography printed by the LaTeX-based export processors
 ‘bibtex’, ‘natbib’ and ‘biblatex’ has a chapter or section heading by
 default, while the ‘basic’ and ‘csl’ processors print the list of
 bibliography entries without a heading.
 
    A document may contain more than one ‘PRINT_BIBLIOGRAPHY’ keywords.
 Each of the keywords will trigger printing the bibliography.
 
    The keywords can be used with or without additional options.  Options
 can be used, for example, to print only entries that belong to a certain
 category or to control formatting.  The set of supported
 ‘PRINT_BIBLIOGRAPHY’ options and their interpretation varies between the
 different citation export processors.  Some export processors do not
 support passing options.

 15.3.1 Bibliography options in the ‘biblatex’ and ‘csl’ export processors
 -------------------------------------------------------------------------
 
 The ‘biblatex’ and ‘csl’ export processors support bibliography options
 through a property list attached to the ‘PRINT_BIBLIOGRAPHY’ keyword.
 For example,
 
      #+print_bibliography: :keyword algebra :type book
 
    Values including spaces must be surrounded with double quotes.  If
 you need to use a key multiple times, you can separate its values with
 commas, but without any space in-between:
 
      #+print_bibliography: :keyword "algebraic logic" :nottype article,book
 
    The ‘biblatex’ export processor accepts all options supported by
 BibLaTeX’s ‘\printbibliography’ command.
 
    The ‘csl’ processor accepts the following options:
 
 ‘:keyword <keyword(,keyword2...)>’
      Print only entries whose keyword field contains all given keywords.
 
 ‘:notkeyword <keyword(,keyword2...)>’
      Print only entries whose keyword field does not contain any of the
      given keywords.
 
 ‘:type <entrytype>’
      Print only entries whose type is ‘<entrytype>’.  Entry type is the
      BibTeX/BibLaTeX entry type if this information is available (the
      entry was read from a BibTeX/BibLaTeX bibliography) and the CSL
      entry type otherwise.
 
 ‘:nottype <entrytype(,entrytype2...)>’
      Print only entries whose type is not among the given entry types.
      Entry type is determined as in the case of ‘:type’.
 
 ‘:csltype <entrytype>’
      Print only entries whose CSL entry type (possibly based on a
      conversion from BibTeX/BibLaTeX to CSL) is ‘<entrytype>’.
 
 ‘:notcsltype <entrytype(,entrytype2...)>’
      Print only entries whose CSL entry type (possibly based on a
      conversion from BibTeX/BibLaTeX to CSL) is not among the listed
      entry types.
 
 ‘:filter <predicate>’
      Print only entries for which the given Emacs Lisp predicate returns
      a non-‘nil’ value.

 16 Working with Source Code
 ***************************
 
 Source code here refers to any plain text collection of computer
 instructions, possibly with comments, written using a human-readable
 programming language.  Org can manage source code in an Org document
 when the source code is identified with begin and end markers.  Working
 with source code begins with identifying source code blocks.  A source
 code block can be placed almost anywhere in an Org document; it is not
 restricted to the preamble or the end of the document.  However, Org
 cannot manage a source code block if it is placed inside an Org comment
 or within a fixed width section.
 
    Here is an example source code block in the Emacs Lisp language:
 
      #+BEGIN_SRC emacs-lisp
        (defun org-xor (a b)
           "Exclusive or."
           (if a (not b) b))
      #+END_SRC
 
    Source code blocks are one of many Org block types, which also
 include “center”, “comment”, “dynamic”, “example”, “export”, “quote”,
 “special”, and “verse”.  This section pertains to blocks between
 ‘#+BEGIN_SRC’ and ‘#+END_SRC’.

 16.1 Features Overview
 ======================
 
 Org can manage the source code in the block delimited by ‘#+BEGIN_SRC’
 ... ‘#+END_SRC’ in several ways that can simplify housekeeping tasks
 essential to modern source code maintenance.  Org can edit, format,
 extract, export, and publish source code blocks.  Org can also compile
 and execute a source code block, then capture the results.  The Org mode
 literature sometimes refers to source code blocks as _live code_ blocks
 because they can alter the content of the Org document or the material
 that it exports.  Users can control the “liveliness” of each source code
 block by tweaking the header arguments (see *note Using Header
 Arguments::) for compiling, execution, extraction, and exporting.
 
    For editing and formatting a source code block, Org uses an
 appropriate Emacs major mode that includes features specifically
 designed for source code in that language.
 
    Org can extract one or more source code blocks and write them to one
 or more source files—a process known as _tangling_ in literate
 programming terminology.
 
    For exporting and publishing, Org’s backends can format a source code
 block appropriately, often with native syntax highlighting.
 
    For executing and compiling a source code block, the user can
 configure Org to select the appropriate compiler.  Org provides
 facilities to collect the result of the execution or compiler output,
 insert it into the Org document, and/or export it.  In addition to text
 results, Org can insert links to other data types, including audio,
 video, and graphics.  Org can also link a compiler error message to the
 appropriate line in the source code block.
 
    An important feature of Org’s management of source code blocks is the
 ability to pass variables, functions, and results to one another using a
 common syntax for source code blocks in any language.  Although most
 literate programming facilities are restricted to one language or
 another, Org’s language-agnostic approach lets the literate programmer
 match each programming task with the appropriate computer language and
 to mix them all together in a single Org document.  This
 interoperability among languages explains why Org’s source code
 management facility was named _Org Babel_ by its originators, Eric
 Schulte and Dan Davison.
 
    Org mode fulfills the promise of easy verification and maintenance of
 publishing reproducible research by keeping text, data, code,
 configuration settings of the execution environment, the results of the
 execution, and associated narratives, claims, references, and internal
 and external links in a single Org document.
 
 
 File: org.info,  Node: Structure of Code Blocks,  Next: Using Header Arguments,  Prev: Features Overview,  Up: Working with Source Code
 
 16.2 Structure of Code Blocks
 =============================
 
 Org offers two ways to structure source code in Org documents: in a
 source code block, and directly inline.  Both specifications are shown
 below.
 
    A source code block conforms to this structure:
 
      #+NAME: <name>
      #+BEGIN_SRC <language> <switches> <header arguments>
        <body>
      #+END_SRC
 
    Do not be put-off by having to remember the source block syntax.  Org
 mode offers a command for wrapping existing text in a block (see *note
 Structure Templates::).  Org also works with other completion systems in
 Emacs, some of which predate Org and have custom domain-specific
 languages for defining templates.  Regular use of templates reduces
 errors, increases accuracy, and maintains consistency.
 
    An inline code block conforms to this structure:
 
      src_<language>{<body>}
 
 or
 
      src_<language>[<header arguments>]{<body>}
 
 ‘#+NAME: <name>’
      Optional.  Names the source block so it can be called, like a
      function, from other source blocks or inline code to evaluate or to
      capture the results.  Code from other blocks, other files, and from
      table formulas (see *note The Spreadsheet::) can use the name to
      reference a source block.  This naming serves the same purpose as
      naming Org tables.  Org mode requires unique names.  For duplicate
      names, Org mode’s behavior is undefined.  Inline code blocks cannot
      have a name.
 
 ‘#+BEGIN_SRC’ ... ‘#+END_SRC’
      Mandatory.  They mark the start and end of a block that Org
      requires.  The ‘#+BEGIN_SRC’ line takes additional arguments, as
      described next.
 
 ‘<language>’
      Optional.  It is the identifier of the source code language in the
      block.  See *note Languages::, for identifiers of supported
      languages.
 
      When ‘<language>’ identifier is omitted, the block also cannot have
      ‘<switches>’ and ‘<header arguments>’.
 
      Language identifier is also used to fontify code blocks in Org
      buffers, when ‘org-src-fontify-natively’ is set to non-‘nil’.  See
      *note Editing Source Code::.
 
 ‘<switches>’
      Optional.  Switches provide finer control of the code execution,
      export, and format (see the discussion of switches in *note Literal
      Examples::).
 
 ‘<header arguments>’
      Optional.  Heading arguments control many aspects of evaluation,
      export and tangling of code blocks (see *note Using Header
      Arguments::).  Using Org’s properties feature, header arguments can
      be selectively applied to the entire buffer or specific subtrees of
      the Org document.
 
 ‘<body>’
      Source code in the dialect of the specified language identifier.

 16.3 Using Header Arguments
 ===========================
 
 Org comes with many header arguments common to all languages.  New
 header arguments are added for specific languages as they become
 available for use in source code blocks.  A header argument is specified
 with an initial colon followed by the argument’s name in lowercase.
 
    Since header arguments can be set in several ways, Org prioritizes
 them in case of overlaps or conflicts by giving local settings a higher
 priority.  Header values in function calls, for example, override header
 values from global defaults.
 
 System-wide header arguments
 ----------------------------
 
 System-wide values of header arguments can be specified by customizing
 the ‘org-babel-default-header-args’ variable, which defaults to the
 following values:
 
      :session    => "none"
      :results    => "replace"
      :exports    => "code"
      :cache      => "no"
      :noweb      => "no"
      :hlines     => "no"
      :tangle     => "no"
 
    Inline source blocks (see *note Structure of Code Blocks::) use
 slightly different default header arguments defined in
 ‘org-babel-default-inline-header-args’:
 
      :session    => "none"
      :results    => "replace"
      :exports    => "results"
      :hlines     => "yes"
 
    The most notable difference between default header arguments for
 inline and normal source blocks is ‘:exports’ argument.  For inline
 source blocks, results of evaluation are exported by default; not the
 code.
 
    Unlike the default values, header arguments set using Org mode
 properties (see *note Header arguments in Org mode properties::) do
 apply to both the normal source blocks and inline source blocks.
 
    The example below sets ‘:noweb’ header arguments to ‘yes’, which
 makes Org expand ‘:noweb’ references by default.
 
      (setq org-babel-default-header-args
            (cons '(:noweb . "yes")
                  (assq-delete-all :noweb org-babel-default-header-args)))
 
    Each language can have separate default header arguments by
 customizing the variable ‘org-babel-default-header-args:<LANG>’, where
 <LANG> is the name of the language.  For details, see the
 language-specific online documentation at
 <https://orgmode.org/worg/org-contrib/babel/>.
 
 Header arguments in Org mode properties
 ---------------------------------------
 
 For header arguments applicable to the buffer, use ‘PROPERTY’ keyword
 anywhere in the Org file (see *note Property Syntax::).
 
    The following example makes all the R code blocks execute in the same
 session.  Setting ‘:results’ to ‘silent’ ignores the results of
 executions for all blocks, not just R code blocks; no results inserted
 for any block.
 
      #+PROPERTY: header-args:R  :session *R*
      #+PROPERTY: header-args    :results silent
 
    Header arguments set through Org’s property drawers (see *note
 Property Syntax::) apply at the subtree level on down.  Since these
 property drawers can appear anywhere in the file hierarchy, Org uses
 outermost call or source block to resolve the values.  Org ignores
 ‘org-use-property-inheritance’ setting.
 
    In this example, ‘:cache’ defaults to ‘yes’ for all code blocks in
 the subtree.
 
      * sample header
        :PROPERTIES:
        :header-args:    :cache yes
        :END:
 
    Properties defined through ‘org-set-property’ function, bound to ‘C-c
 C-x p’, apply to all active languages.  They override properties set in
 ‘org-babel-default-header-args’.
 
    Language-specific header arguments are also read from properties
 ‘header-args:<LANG>’ where <LANG> is the language identifier.  For
 example,
 
      * Heading
        :PROPERTIES:
        :header-args:clojure:    :session *clojure-1*
        :header-args:R:          :session *R*
        :END:
      ** Subheading
        :PROPERTIES:
        :header-args:clojure:    :session *clojure-2*
        :END:
 
 would force separate sessions for Clojure blocks in ‘Heading’ and
 ‘Subheading’, but use the same session for all R blocks.  Blocks in
 ‘Subheading’ inherit settings from ‘Heading’.
 
 Code block specific header arguments
 ------------------------------------
 
 Header arguments are most commonly set at the source code block level,
 on the ‘#+BEGIN_SRC’ line.  Arguments set at this level take precedence
 over those set in the ‘org-babel-default-header-args’ variable, and also
 those set as header properties.
 
    In the following example, setting ‘:results’ to ‘silent’ makes it
 ignore results of the code execution.  Setting ‘:exports’ to ‘code’
 exports only the body of the code block to HTML or LaTeX.
 
      #+NAME: factorial
      #+BEGIN_SRC haskell :results silent :exports code :var n=0
        fac 0 = 1
        fac n = n * fac (n-1)
      #+END_SRC
 
    The same header arguments in an inline code block:
 
      src_haskell[:exports both]{fac 5}
 
    Code block header arguments can span multiple lines using ‘#+HEADER:’
 on each line.  Note that Org currently accepts the plural spelling of
 ‘#+HEADER:’ only as a convenience for backward-compatibility.  It may be
 removed at some point.
 
    Multi-line header arguments on an unnamed code block:
 
      #+HEADER: :var data1=1
      #+BEGIN_SRC emacs-lisp :var data2=2
         (message "data1:%S, data2:%S" data1 data2)
      #+END_SRC
 
      #+RESULTS:
      : data1:1, data2:2
 
    Multi-line header arguments on a named code block:
 
      #+NAME: named-block
      #+HEADER: :var data=2
      #+BEGIN_SRC emacs-lisp
        (message "data:%S" data)
      #+END_SRC
 
      #+RESULTS: named-block
        : data:2
 
 Header arguments in function calls
 ----------------------------------
 
 Header arguments in function calls are the most specific and override
 all other settings in case of an overlap.  They get the highest
 priority.  Two ‘#+CALL:’ examples are shown below.  For the complete
 syntax of ‘CALL’ keyword, see *note Evaluating Code Blocks::.
 
    In this example, ‘:exports results’ header argument is applied to the
 evaluation of the ‘#+CALL:’ line.
 
      #+CALL: factorial(n=5) :exports results
 
    In this example, ‘:session special’ header argument is applied to the
 evaluation of ‘factorial’ code block.
 
      #+CALL: factorial[:session special](n=5)

 16.4 Environment of a Code Block
 ================================
 
 Passing arguments
 -----------------
 
 Use ‘var’ for passing arguments to source code blocks.  The specifics of
 variables in code blocks vary by the source language and are covered in
 the language-specific documentation.  The syntax for ‘var’, however, is
 the same for all languages.  This includes declaring a variable, and
 assigning a default value.
 
    The following syntax is used to pass arguments to code blocks using
 the ‘var’ header argument.
 
      :var NAME=ASSIGN
 
 NAME is the name of the variable bound in the code block body.  ASSIGN
 is a literal value, such as a string, a number, a reference to a table,
 a list, a literal example, another code block—with or without
 arguments—or the results of evaluating a code block.  ASSIGN may specify
 a filename for references to elements in a different file, using a ‘:’
 to separate the filename from the reference.
 
      :var NAME=FILE:REFERENCE
 
    When ‘FILE’ does not exist, the reference is searched in the current
 file, using the verbatim reference.  This way, ‘:var table=tbl:example’
 will be searched inside the current buffer.
 
    Here are examples of passing values by reference:
 
 table
      A table named with a ‘NAME’ keyword.
 
           #+NAME: example-table
           | 1 |
           | 2 |
           | 3 |
           | 4 |
 
           #+NAME: table-length
           #+BEGIN_SRC emacs-lisp :var table=example-table
             (length table)
           #+END_SRC
 
           #+RESULTS: table-length
           : 4
 
      When passing a table, you can treat specially the row, or the
      column, containing labels for the columns, or the rows, in the
      table.
 
      The ‘colnames’ header argument accepts ‘yes’, ‘no’, or ‘nil’
      values.  The default value is ‘nil’: if an input table has column
      names—because the second row is a horizontal rule—then Org removes
      the column names, processes the table, puts back the column names,
      and then writes the table to the results block.  Using ‘yes’, Org
      does the same to the first non-hline row, even if the initial table
      does not contain any horizontal rule.  When set to ‘no’, Org does
      not pre-process column names at all.
 
           #+NAME: less-cols
           | a |
           |---|
           | b |
           | c |
 
           #+BEGIN_SRC python :var tab=less-cols :colnames nil
           return [[val + '*' for val in row] for row in tab]
           #+END_SRC
 
           #+RESULTS:
           | a  |
           |----|
           | b* |
           | c* |
 
      Similarly, the ‘rownames’ header argument can take two values:
      ‘yes’ or ‘no’.  When set to ‘yes’, Org removes the first column,
      processes the table, puts back the first column, and then writes
      the table to the results block.  The default is ‘no’, which means
      Org does not pre-process the first column.  Note that Emacs Lisp
      code blocks ignore ‘rownames’ header argument because of the ease
      of table-handling in Emacs.
 
           #+NAME: with-rownames
           | one | 1 | 2 | 3 | 4 |  5 |
           | two | 6 | 7 | 8 | 9 | 10 |
 
           #+BEGIN_SRC python :var tab=with-rownames :rownames yes
           return [[val + 10 for val in row] for row in tab]
           #+END_SRC
 
           #+RESULTS:
           | one | 11 | 12 | 13 | 14 | 15 |
           | two | 16 | 17 | 18 | 19 | 20 |
 
    To refer to a table in another file, join the filename and table name
 with a colon, for example: ‘:var table=other-file.org:example-table’.
 
 list
      A simple named list.
 
           #+NAME: example-list
           - simple
             - not
             - nested
           - list
 
           #+BEGIN_SRC emacs-lisp :var x=example-list
             (print x)
           #+END_SRC
 
           #+RESULTS:
           | simple | list |
 
      Note that only the top level list items are passed along.  Nested
      list items are ignored.
 
 code block without arguments
      A code block name, as assigned by ‘NAME’ keyword from the example
      above, optionally followed by parentheses.
 
           #+BEGIN_SRC emacs-lisp :var length=table-length()
             (* 2 length)
           #+END_SRC
 
           #+RESULTS:
           : 8
 
 code block with arguments
      A code block name, as assigned by ‘NAME’ keyword, followed by
      parentheses and optional arguments passed within the parentheses.
      The block is evaluated with point at its location.
 
           #+NAME: double
           #+BEGIN_SRC emacs-lisp :var input=8
             (* 2 input)
           #+END_SRC
 
           #+RESULTS: double
           : 16
 
           #+NAME: squared
           #+BEGIN_SRC emacs-lisp :var input=double(input=1)
             (* input input)
           #+END_SRC
 
           #+RESULTS: squared
           : 4
 
 literal example, or code block contents
      A code block or literal example block named with a ‘NAME’ keyword,
      followed by brackets (optional for example blocks).
 
           #+NAME: literal-example
           #+BEGIN_EXAMPLE
             A literal example
             on two lines
           #+END_EXAMPLE
 
           #+NAME: read-literal-example
           #+BEGIN_SRC emacs-lisp :var x=literal-example[]
             (concatenate #'string x " for you.")
           #+END_SRC
 
           #+RESULTS: read-literal-example
           : A literal example
           : on two lines for you.
 
    Indexing variable values enables referencing portions of a variable.
 Indexes are 0 based with negative values counting backwards from the
 end.  If an index is separated by commas then each subsequent section
 indexes as the next dimension.  Note that this indexing occurs _before_
 other table-related header arguments are applied, such as ‘hlines’,
 ‘colnames’ and ‘rownames’.  The following example assigns the last cell
 of the first row the table ‘example-table’ to the variable ‘data’:
 
      #+NAME: example-table
      | 1 | a |
      | 2 | b |
      | 3 | c |
      | 4 | d |
 
      #+BEGIN_SRC emacs-lisp :var data=example-table[0,-1]
        data
      #+END_SRC
 
      #+RESULTS:
      : a
 
    Two integers separated by a colon reference a range of variable
 values.  In that case the entire inclusive range is referenced.  For
 example the following assigns the middle three rows of ‘example-table’
 to ‘data’.
 
      #+NAME: example-table
      | 1 | a |
      | 2 | b |
      | 3 | c |
      | 4 | d |
      | 5 | 3 |
 
      #+BEGIN_SRC emacs-lisp :var data=example-table[1:3]
        data
      #+END_SRC
 
      #+RESULTS:
      | 2 | b |
      | 3 | c |
      | 4 | d |
 
    To pick the entire range, use an empty index, or the single character
 ‘*’.  ‘0:-1’ does the same thing.  Example below shows how to reference
 the first column only.
 
      #+NAME: example-table
      | 1 | a |
      | 2 | b |
      | 3 | c |
      | 4 | d |
 
      #+BEGIN_SRC emacs-lisp :var data=example-table[,0]
        data
      #+END_SRC
 
      #+RESULTS:
      | 1 | 2 | 3 | 4 |
 
    Index referencing can be used for tables and code blocks.  Index
 referencing can handle any number of dimensions.  Commas delimit
 multiple dimensions, as shown below.
 
      #+NAME: 3D
      #+BEGIN_SRC emacs-lisp
        '(((1  2  3)  (4  5  6)  (7  8  9))
          ((10 11 12) (13 14 15) (16 17 18))
          ((19 20 21) (22 23 24) (25 26 27)))
      #+END_SRC
 
      #+BEGIN_SRC emacs-lisp :var data=3D[1,,1]
        data
      #+END_SRC
 
      #+RESULTS:
      | 11 | 14 | 17 |
 
    Note that row names and column names are not removed prior to
 variable indexing.  You need to take them into account, even when
 ‘colnames’ or ‘rownames’ header arguments remove them.
 
    Emacs lisp code can also set the values for variables.  To
 differentiate a value from Lisp code, Org interprets any value starting
 with ‘(’, ‘[’, ‘'’ or ‘`’ as Emacs Lisp code.  The result of evaluating
 that code is then assigned to the value of that variable.  The following
 example shows how to reliably query and pass the file name of the Org
 mode buffer to a code block using headers.  We need reliability here
 because the file’s name could change once the code in the block starts
 executing.
 
      #+BEGIN_SRC sh :var filename=(buffer-file-name) :exports both
        wc -w $filename
      #+END_SRC
 
    Note that values read from tables and lists are not mistakenly
 evaluated as Emacs Lisp code, as illustrated in the following example.
 
      #+NAME: table
      | (a b c) |
 
      #+HEADER: :var data=table[0,0]
      #+BEGIN_SRC perl
        $data
      #+END_SRC
 
      #+RESULTS:
      : (a b c)
 
 Using sessions
 --------------
 
 Two code blocks can share the same environment.  The ‘session’ header
 argument is for running multiple source code blocks under one session.
 Org runs code blocks with the same session name in the same interpreter
 process.
 
 ‘none’
      Default.  Each code block gets a new interpreter process to
      execute.  The process terminates once the block is evaluated.
 
 STRING
      Any string besides ‘none’ turns that string into the name of that
      session.  For example, ‘:session STRING’ names it ‘STRING’.  If
      ‘session’ has no value, then the session name is derived from the
      source language identifier.  Subsequent blocks with the same source
      code language use the same session.  Depending on the language,
      state variables, code from other blocks, and the overall
      interpreted environment may be shared.  Some interpreted languages
      support concurrent sessions when subsequent source code language
      blocks change session names.
 
    Only languages that provide interactive evaluation can have session
 support.  Not all languages provide this support, such as C and ditaa.
 Even languages, such as Python and Haskell, that do support interactive
 evaluation impose limitations on allowable language constructs that can
 run interactively.  Org inherits those limitations for those code blocks
 running in a session.
 
 Choosing a working directory
 ----------------------------
 
 The ‘dir’ header argument specifies the default directory during code
 block execution.  If it is absent, then the directory associated with
 the current buffer is used.  In other words, supplying ‘:dir DIRECTORY’
 temporarily has the same effect as changing the current directory with
 ‘M-x cd <RET> DIRECTORY’, and then not setting ‘dir’.  Under the
 surface, ‘dir’ simply sets the value of the Emacs variable
 ‘default-directory’.  Setting ‘mkdirp’ header argument to a non-‘nil’
 value creates the directory, if necessary.
 
    Setting ‘dir’ to the symbol ‘attach’ or the string ‘"'attach"’ will
 set ‘dir’ to the directory returned by ‘(org-attach-dir)’, set ‘:mkdir
 yes’, and insert any file paths, as when using ‘:results file’, which
 are under the node’s attachment directory using ‘attachment:’ links
 instead of the usual ‘file:’ links.  Any returned path outside of the
 attachment directory will use ‘file:’ links as per usual.
 
    For example, to save the plot file in the ‘Work/’ folder of the home
 directory—notice tilde is expanded:
 
      #+BEGIN_SRC R :file myplot.png :dir ~/Work
        matplot(matrix(rnorm(100), 10), type="l")
      #+END_SRC
 
    To evaluate the code block on a remote machine, supply a remote
 directory name using Tramp syntax.  For example:
 
      #+BEGIN_SRC R :file plot.png :dir /scp:dand@yakuba.princeton.edu:
        plot(1:10, main=system("hostname", intern=TRUE))
      #+END_SRC
 
    Org first captures the text results as usual for insertion in the Org
 file.  Then Org also inserts a link to the remote file, thanks to Emacs
 Tramp.  Org constructs the remote path to the file name from ‘dir’ and
 ‘default-directory’, as illustrated here:
 
      [[file:/scp:dand@yakuba.princeton.edu:/home/dand/plot.png][plot.png]]
 
    When ‘dir’ is used with ‘session’, Org sets the starting directory
 for a new session.  But Org does not alter the directory of an already
 existing session.
 
    Do not use ‘dir’ with ‘:exports results’ or with ‘:exports both’ to
 avoid Org inserting incorrect links to remote files.  That is because
 Org does not expand ‘default directory’ to avoid some underlying
 portability issues.
 
 Inserting headers and footers
 -----------------------------
 
 The ‘prologue’ header argument is for appending to the top of the code
 block for execution, like a reset instruction.  For example, you may use
 ‘:prologue "reset"’ in a Gnuplot code block or, for every such block:
 
      (add-to-list 'org-babel-default-header-args:gnuplot
                   '((:prologue . "reset")))
 
 
    Likewise, the value of the ‘epilogue’ header argument is for
 appending to the end of the code block for execution.

 16.5 Evaluating Code Blocks
 ===========================
 
 A note about security: With code evaluation comes the risk of harm.  Org
 safeguards by prompting for user’s permission before executing any code
 in the source block.  To customize this safeguard, or disable it, see
 *note Code Evaluation Security::.
 
 How to evaluate source code
 ---------------------------
 
 Org captures the results of the code block evaluation and inserts them
 in the Org file, right after the code block.  The insertion point is
 after a newline and the ‘RESULTS’ keyword.  Org creates the ‘RESULTS’
 keyword if one is not already there.  More details in *note Results of
 Evaluation::.
 
    By default, Org enables only Emacs Lisp code blocks for execution.
 See *note Languages:: to enable other languages.
 
    Org provides many ways to execute code blocks.  ‘C-c C-c’ or ‘C-c C-v
 e’ with the point on a code block(1) calls the
 ‘org-babel-execute-src-block’ function, which executes the code in the
 block, collects the results, and inserts them in the buffer.
 
    By calling a named code block(2) from an Org mode buffer or a table.
 Org can call the named code blocks from the current Org mode buffer or
 from the “Library of Babel” (see *note Library of Babel::).
 
    The syntax for ‘CALL’ keyword is:
 
      #+CALL: <name>(<arguments>)
      #+CALL: <name>[<inside header arguments>](<arguments>) <end header arguments>
 
    The syntax for inline named code blocks is:
 
      ... call_<name>(<arguments>) ...
      ... call_<name>[<inside header arguments>](<arguments>)[<end header arguments>] ...
 
    When inline syntax is used, the result is wrapped based on the
 variable ‘org-babel-inline-result-wrap’, which by default is set to
 ‘"=%s="’ to produce verbatim text suitable for markup.
 
 ‘<name>’
      This is the name of the code block (see *note Structure of Code
      Blocks::) to be evaluated in the current document.  If the block is
      located in another file, start ‘<name>’ with the file name followed
      by a colon.  For example, in order to execute a block named
      ‘clear-data’ in ‘file.org’, you can write the following:
 
           #+CALL: file.org:clear-data()
 
 ‘<arguments>’
      Org passes arguments to the code block using standard function call
      syntax.  For example, a ‘#+CALL:’ line that passes ‘4’ to a code
      block named ‘double’, which declares the header argument ‘:var
      n=2’, would be written as:
 
           #+CALL: double(n=4)
 
      Note how this function call syntax is different from the header
      argument syntax.
 
 ‘<inside header arguments>’
      Org passes inside header arguments to the named code block using
      the header argument syntax.  Inside header arguments apply to code
      block evaluation.  For example, ‘[:results output]’ collects
      results printed to stdout during code execution of that block.
      Note how this header argument syntax is different from the function
      call syntax.
 
 ‘<end header arguments>’
      End header arguments affect the results returned by the code block.
      For example, ‘:results html’ wraps the results in a ‘#+BEGIN_EXPORT
      html’ block before inserting the results in the Org buffer.
 
 Limit code block evaluation
 ---------------------------
 
 The ‘eval’ header argument can limit evaluation of specific code blocks
 and ‘CALL’ keyword.  It is useful for protection against evaluating
 untrusted code blocks by prompting for a confirmation.
 
 ‘yes’
      Org evaluates the source code, possibly asking permission according
      to ‘org-confirm-babel-evaluate’.
 
 ‘never’ or ‘no’
      Org never evaluates the source code.
 
 ‘query’
      Org prompts the user for permission to evaluate the source code.
 
 ‘never-export’ or ‘no-export’
      Org does not evaluate the source code when exporting, yet the user
      can evaluate it interactively.
 
 ‘query-export’
      Org prompts the user for permission to evaluate the source code
      during export.
 
    If ‘eval’ header argument is not set, then Org determines whether to
 evaluate the source code from the ‘org-confirm-babel-evaluate’ variable
 (see *note Code Evaluation Security::).
 
 Cache results of evaluation
 ---------------------------
 
 The ‘cache’ header argument is for caching results of evaluating code
 blocks.  Caching results can avoid re-evaluating a code block that have
 not changed since the previous run.  To benefit from the cache and avoid
 redundant evaluations, the source block must have a result already
 present in the buffer, and neither the header arguments—including the
 value of ‘var’ references—nor the text of the block itself has changed
 since the result was last computed.  This feature greatly helps avoid
 long-running calculations.  For some edge cases, however, the cached
 results may not be reliable.
 
    The caching feature is best for when code blocks are pure functions,
 that is functions that return the same value for the same input
 arguments (see *note Environment of a Code Block::), and that do not
 have side effects, and do not rely on external variables other than the
 input arguments.  Functions that depend on a timer, file system objects,
 and random number generators are clearly unsuitable for caching.
 
    A note of warning: when ‘cache’ is used in a session, caching may
 cause unexpected results.
 
    When the caching mechanism tests for any source code changes, it does
 not expand noweb style references (see *note Noweb Reference Syntax::).
 
    The ‘cache’ header argument can have one of two values: ‘yes’ or
 ‘no’.
 
 ‘no’
      Default.  No caching of results; code block evaluated every time.
 
 ‘yes’
      Whether to run the code or return the cached results is determined
      by comparing the SHA1 hash value of the combined code block and
      arguments passed to it.  This hash value is packed on the
      ‘#+RESULTS:’ line from previous evaluation.  When hash values
      match, Org does not evaluate the code block.  When hash values
      mismatch, Org evaluates the code block, inserts the results,
      recalculates the hash value, and updates ‘#+RESULTS:’ line.
 
    In this example, both functions are cached.  But ‘caller’ runs only
 if the result from ‘random’ has changed since the last run.
 
      #+NAME: random
      #+BEGIN_SRC R :cache yes

 16.6 Results of Evaluation
 ==========================
 
 How Org handles results of a code block execution depends on many header
 arguments working together.  The primary determinant, however, is the
 ‘results’ header argument.  It accepts four classes of options.  Each
 code block can take only one option per class:
 
 Collection
      For how the results should be collected from the code block;
 
 Type
      For which type of result the code block will return; affects how
      Org processes and inserts results in the Org buffer;
 
 Format
      For the result; affects how Org processes results;
 
 Handling
      For inserting results once they are properly formatted.
 
 Collection
 ----------
 
 Collection options specify the results.  Choose one of the options; they
 are mutually exclusive.
 
 ‘value’
      Default for most Babel libraries(1).  Functional mode.  Org gets
      the value by wrapping the code in a function definition in the
      language of the source block.  That is why when using ‘:results
      value’, code should execute like a function and return a value.
      For languages like Python, an explicit ‘return’ statement is
      mandatory when using ‘:results value’.  Result is the value
      returned by the last statement in the code block.
 
      When evaluating the code block in a session (see *note Environment
      of a Code Block::), Org passes the code to an interpreter running
      as an interactive Emacs inferior process.  Org gets the value from
      the source code interpreter’s last statement output.  Org has to
      use language-specific methods to obtain the value.  For example,
      from the variable ‘_’ in Ruby, and the value of ‘.Last.value’ in R.
 
 ‘output’
      Scripting mode.  Org passes the code to an external process running
      the interpreter.  Org returns the contents of the standard output
      stream as text results.
 
      When using a session, Org passes the code to the interpreter
      running as an interactive Emacs inferior process.  Org concatenates
      any text output from the interpreter and returns the collection as
      a result.
 
 Type
 ----
 
 Type tells what result types to expect from the execution of the code
 block.  Choose one of the options; they are mutually exclusive.
 
    The default behavior is to automatically determine the result type.
 The result type detection depends on the code block language, as
 described in the documentation for individual languages.  See *note
 Languages::.
 
 ‘table’
 ‘vector’
      Interpret the results as an Org table.  If the result is a single
      value, create a table with one row and one column.  Usage example:
      ‘:results value table’.
 
      In-between each table row or below the table headings, sometimes
      results have horizontal lines, which are also known as “hlines”.
      The ‘hlines’ argument with the default ‘no’ value strips such lines
      from the input table.  For most code, this is desirable, or else
      those ‘hline’ symbols raise unbound variable errors.  A ‘yes’
      accepts such lines, as demonstrated in the following example.
 
           #+NAME: many-cols
           | a | b | c |
           |---+---+---|
           | d | e | f |
           |---+---+---|
           | g | h | i |
 
           #+NAME: no-hline
           #+BEGIN_SRC python :var tab=many-cols :hlines no
           return tab
           #+END_SRC
 
           #+RESULTS: no-hline
           | a | b | c |
           | d | e | f |
           | g | h | i |
 
           #+NAME: hlines
           #+BEGIN_SRC python :var tab=many-cols :hlines yes
           return tab
           #+END_SRC
 
           #+RESULTS: hlines
           | a | b | c |
           |---+---+---|
           | d | e | f |
           |---+---+---|
           | g | h | i |
 
 ‘list’
      Interpret the results as an Org list.  If the result is a single
      value, create a list of one element.
 
 ‘scalar’
 ‘verbatim’
      Interpret literally and insert as quoted text.  Do not create a
      table.  Usage example: ‘:results value verbatim’.
 
 ‘file’
      Interpret as a filename.  Save the results of execution of the code
      block to that file, then insert a link to it.  You can control both
      the filename and the description associated to the link.
 
      Org first tries to generate the filename from the value of the
      ‘file’ header argument and the directory specified using the
      ‘output-dir’ header arguments.  If ‘output-dir’ is not specified,
      Org assumes it is the current directory.
 
           #+BEGIN_SRC asymptote :results value file :file circle.pdf :output-dir img/
             size(2cm);
             draw(unitcircle);
           #+END_SRC
 
      If ‘file’ header argument is missing, Org generates the base name
      of the output file from the name of the code block, and its
      extension from the ‘file-ext’ header argument.  In that case, both
      the name and the extension are mandatory.
 
      Result can also be interpreted as path to file.  See ‘:results
      link’.
 
           #+name: circle
           #+BEGIN_SRC asymptote :results value file :file-ext pdf
             size(2cm);
             draw(unitcircle);
           #+END_SRC
 
      The ‘file-desc’ header argument defines the description (see *note
      Link Format::) for the link.  If ‘file-desc’ is present but has no
      value, the ‘file’ value is used as the link description.  When this
      argument is not present, the description is omitted.  If you want
      to provide the ‘file-desc’ argument but omit the description, you
      can provide it with an empty vector (i.e., :file-desc []).
 
      By default, Org assumes that a table written to a file has
      TAB-delimited output.  You can choose a different separator with
      the ‘sep’ header argument.
 
      The ‘file-mode’ header argument defines the file permissions.  To
      make it executable, use ‘:file-mode (identity #o755)’.
 
           #+BEGIN_SRC shell :results file :file script.sh :file-mode (identity #o755)
             echo "#!/bin/bash"
             echo "echo Hello World"
           #+END_SRC
 
 Format
 ------
 
 Format pertains to the type of the result returned by the code block.
 Choose one of the options; they are mutually exclusive.  The default
 follows from the type specified above.
 
 ‘raw’
      Interpreted as raw Org mode.  Inserted directly into the buffer.
      Aligned if it is a table.  Usage example: ‘:results value raw’.
 
 ‘code’
      Result enclosed in a code block.  Useful for parsing.  Usage
      example: ‘:results value code’.
 
 ‘drawer’
      Results are added directly to the Org file as with ‘raw’, but are
      wrapped in a ‘RESULTS’ drawer or results macro (for inline code
      blocks), for later scripting and automated processing.  Usage
      example: ‘:results value drawer’.
 
 ‘html’
      Results enclosed in a ‘BEGIN_EXPORT html’ block.  Usage example:
      ‘:results value html’.
 
 ‘latex’
      Results enclosed in a ‘BEGIN_EXPORT latex’ block.  Usage example:
      ‘:results value latex’.
 
 ‘link’
 ‘graphics’
      When used along with ‘file’ type, the result is a link to the file
      specified in ‘:file’ header argument.  However, unlike plain ‘file’
      type, code block output is not written to the disk.  The block is
      expected to generate the file by its side-effects only, as in the
      following example:
 
           #+begin_src shell :results file link :file "org-mode-unicorn.svg"
             wget -c "https://orgmode.org/resources/img/org-mode-unicorn.svg"
           #+end_src
 
           #+RESULTS:
           [[file:org-mode-unicorn.svg]]
 
      If ‘:file’ header argument is omitted, interpret source block
      result as the file path.
 
 ‘org’
      Results enclosed in a ‘BEGIN_SRC org’ block.  For comma-escape,
      either ‘<TAB>’ in the block, or export the file.  Usage example:
      ‘:results value org’.
 
 ‘pp’
      Result converted to pretty-print source code.  Enclosed in a code
      block.  Languages supported: Emacs Lisp, Python, and Ruby.  Usage
      example: ‘:results value pp’.
 
    The ‘wrap’ header argument unconditionally marks the results block by
 appending strings to ‘#+BEGIN_’ and ‘#+END_’.  If no string is
 specified, Org wraps the results in a ‘#+BEGIN_results’ ...
 ‘#+END_results’ block.  It takes precedent over the ‘results’ value
 listed above.  E.g.,
 
      #+BEGIN_SRC emacs-lisp :results html :wrap EXPORT markdown
      "<blink>Welcome back to the 90's</blink>"
      #+END_SRC
 
      #+RESULTS:
      #+BEGIN_EXPORT markdown
      <blink>Welcome back to the 90's</blink>
      #+END_EXPORT
 
 Handling
 --------
 
 Handling options after collecting the results.  Choose one of the
 options; they are mutually exclusive.
 
 ‘replace’
      Default.  Insert results in the Org buffer.  Remove previous
      results.  Usage example: ‘:results output replace’.
 
 ‘silent’
      Do not insert results in the Org mode buffer, but echo them in the
      minibuffer.  Usage example: ‘:results output silent’.
 
 ‘none’
      Compute results, but do not do anything with them.  No inserting in
      the Org mode buffer nor echo them in the minibuffer.  The results
      can still be used when referenced from another code block.  Usage
      example: ‘:results none’.
 
 ‘discard’
      Ignore the results completely.  This option is similar to ‘none’,
      but no processing is performed on the return value.  Calling the
      code block programmatically (see *note How to evaluate source
      code::) or by reference (see *note Passing arguments:: and *note
      Noweb Reference Syntax::) will always yield ‘nil’.
 
 ‘append’
      Append results to the Org buffer.  Latest results are at the
      bottom.  Does not remove previous results.  Usage example:
      ‘:results output append’.
 
 ‘prepend’
      Prepend results to the Org buffer.  Latest results are at the top.
      Does not remove previous results.  Usage example: ‘:results output
      prepend’.
 
 Post-processing
 ---------------
 
 The ‘post’ header argument is for post-processing results from block
 evaluation.  When ‘post’ has any value, Org binds the results to
 ‘*this*’ variable for easy passing to ‘var’ header argument
 specifications (see *note Environment of a Code Block::).  That makes
 results available to other code blocks, or even for direct Emacs Lisp
 code execution.
 
    The following two examples illustrate ‘post’ header argument in
 action.  The first one shows how to attach an ‘ATTR_LATEX’ keyword using
 ‘post’.
 
      #+NAME: attr_wrap
      #+BEGIN_SRC sh :var data="" :var width="\\textwidth" :results output
        echo "#+ATTR_LATEX: :width $width"
        echo "$data"
      #+END_SRC
 
      #+HEADER: :file /tmp/it.png
      #+BEGIN_SRC dot :post attr_wrap(width="5cm", data=*this*) :results drawer
        digraph{
                a -> b;
                b -> c;
                c -> a;
        }
      #+end_src
 
      #+RESULTS:
      :RESULTS:
      #+ATTR_LATEX :width 5cm
      [[file:/tmp/it.png]]
      :END:
 
    The second example shows use of ‘colnames’ header argument in ‘post’
 to pass data between code blocks.
 
      #+NAME: round-tbl
      #+BEGIN_SRC emacs-lisp :var tbl="" fmt="%.3f"
        (mapcar (lambda (row)
                  (mapcar (lambda (cell)
                            (if (numberp cell)
                                (format fmt cell)
                              cell))
                          row))
                tbl)
      #+end_src
 
      #+BEGIN_SRC R :colnames yes :post round-tbl[:colnames yes](*this*)
        set.seed(42)
        data.frame(foo=rnorm(1))
      #+END_SRC
 
      #+RESULTS:
      |   foo |
      |-------|
      | 1.371 |

 Settings::).
 
 
 File: org.info,  Node: Exporting Code Blocks,  Next: Extracting Source Code,  Prev: Results of Evaluation,  Up: Working with Source Code
 
 16.7 Exporting Code Blocks
 ==========================
 
 It is possible to export the _code_ of code blocks, the _results_ of
 code block evaluation, _both_ the code and the results of code block
 evaluation, or _none_.  Org defaults to exporting _code_ for most
 languages and _results_ for inline code blocks.  For some languages,
 such as ditaa, Org defaults to _results_ both in ordinary source blocks
 and in inline source blocks.  To export just the body of code blocks,
 see *note Literal Examples::.  To selectively export subtrees of an Org
 document, see *note Exporting::.
 
    The ‘exports’ header argument is to specify if that part of the Org
 file is exported to, say, HTML or LaTeX formats.
 
 ‘code’
      The default.  The body of code is included into the exported file.
      Example: ‘:exports code’.
 
 ‘results’
      The results of evaluation of the code is included in the exported
      file.  Example: ‘:exports results’.
 
 ‘both’
      Both the code and results of evaluation are included in the
      exported file.  Example: ‘:exports both’.
 
 ‘none’
      Neither the code nor the results of evaluation is included in the
      exported file.  Whether the code is evaluated at all depends on
      other options.  Example: ‘:exports none’.
 
    If a source block is named using ‘NAME’ keyword, the same name will
 be assigned to the results of evaluation.  This way, fuzzy links
 pointing to the named source blocks exported using ‘:exports results’
 will remain valid and point to the results of evaluation.
 
    Results of evaluation of a named block can also be explicitly named
 using a separate ‘NAME’ keyword.  The name value set via ‘NAME’ keyword
 will be preferred over the parent source block.
 
      #+NAME: code name
      #+BEGIN_SRC emacs-lisp :exports both value
      (+ 1 2)
      #+END_SRC
 
      #+NAME: results name
      #+RESULTS: code name
      3
 
      This [[code name][link]] will point to the code block.
      Another [[results name][link]] will point to the results.
 
    Explicit setting of the result name may be necessary when a named
 code block is exported using ‘:exports both’.  Links to such block may
 arbitrarily point either to the code block or to its results when
 results do not have a distinct name.
 
    Note that all the links pointing to a source block exported using
 ‘:exports none’ will be broken.  This will make export process fail,
 unless broken links are allowed during export (see *note Export
 Settings::).
 
    To stop Org from evaluating code blocks to speed exports, use the
 header argument ‘:eval never-export’ (see *note Evaluating Code
 Blocks::).  To stop Org from evaluating code blocks for greater
 security, set the ‘org-export-use-babel’ variable to ‘nil’, but
 understand that header arguments will have no effect.
 
    Turning off evaluation comes in handy when batch processing.  For
 example, markup languages for wikis, which have a high risk of untrusted
 code.  Stopping code block evaluation also stops evaluation of all
 header arguments of the code block.  This may not be desirable in some
 circumstances.  So during export, to allow evaluation of just the header
 arguments but not any code evaluation in the source block, set ‘:eval
 never-export’ (see *note Evaluating Code Blocks::).
 
    Org never evaluates code blocks in commented subtrees when exporting
 (see *note Comment Lines::).  On the other hand, Org does evaluate code
 blocks in subtrees excluded from export (see *note Export Settings::).
 
 
 File: org.info,  Node: Extracting Source Code,  Next: Languages,  Prev: Exporting Code Blocks,  Up: Working with Source Code
 
 16.8 Extracting Source Code
 ===========================
 
 Extracting source code from code blocks is a basic task in literate
 programming.  Org has features to make this easy.  In literate
 programming parlance, documents on creation are _woven_ with code and
 documentation, and on export, the code is tangled for execution by a
 computer.  Org facilitates weaving and tangling for producing,
 maintaining, sharing, and exporting literate programming documents.  Org
 provides extensive customization options for extracting source code.
 
    When Org tangles code blocks, it expands, merges, and transforms
 them.  Then Org recomposes them into one or more separate files, as
 configured through the options.  During this tangling process, Org
 expands variables in the source code, and resolves any noweb style
 references (see *note Noweb Reference Syntax::).
 
 Header arguments
 ----------------
 
 The ‘tangle’ header argument specifies if the code block is exported to
 source file(s).
 
 ‘yes’
      Export the code block to source file.  The file name for the source
      file is derived from the name of the Org file, and the file
      extension is derived from the source code language identifier.
      Example: ‘:tangle yes’.
 
 ‘no’
      The default.  Do not extract the code in a source code file.
      Example: ‘:tangle no’.
 
 FILENAME
      Export the code block to source file whose file name is derived
      from any string passed to the ‘tangle’ header argument.  Org
      derives the file name as being relative to the directory of the Org
      file’s location.  Example: ‘:tangle FILENAME’.
 
    The ‘mkdirp’ header argument creates parent directories for tangled
 files if the directory does not exist.  A ‘yes’ value enables directory
 creation whereas ‘no’ inhibits it.
 
    The ‘comments’ header argument controls inserting comments into
 tangled files.  These are above and beyond whatever comments may already
 exist in the code block.
 
 ‘no’
      The default.  Do not insert any extra comments during tangling.
 
 ‘link’
      Wrap the code block in comments.  Include links pointing back to
      the place in the Org file from where the code was tangled.
 
 ‘yes’
      Kept for backward compatibility; same as ‘link’.
 
 ‘org’
      Nearest headline text from Org file is inserted as comment.  The
      exact text that is inserted is picked from the leading context of
      the source block.
 
 ‘both’
      Includes both ‘link’ and ‘org’ options.
 
 ‘noweb’
      Includes ‘link’ option, expands noweb references (see *note Noweb
      Reference Syntax::), and wraps them in link comments inside the
      body of the code block.
 
    The ‘padline’ header argument controls insertion of newlines to pad
 source code in the tangled file.
 
 ‘yes’
      Default.  Insert a newline before and after each code block in the
      tangled file.
 
 ‘no’
      Do not insert newlines to pad the tangled code blocks.
 
    The ‘shebang’ header argument can turn results into executable script
 files.  By setting it to a string value—for example, ‘:shebang
 "#!/bin/bash"’—Org inserts that string as the first line of the tangled
 file that the code block is extracted to.  Org then turns on the tangled
 file’s executable permission.
 
    The ‘tangle-mode’ header argument specifies what permissions to set
 for tangled files by ‘set-file-modes’.  Permissions are given by an
 octal value, which can be provided calling the ‘identity’ function on an
 elisp octal value.  For instance, to create a read-only file one may use
 ‘:tangle-mode (identity #o444)’.  To reduce the verbosity required, a
 octal shorthand is defined, ‘oXXX’ (‘o’ for octal).  Using this, our
 read-only example is ‘:tangle-mode o444’.  Omitting the ‘o’ prefix will
 cause the argument to be interpreted as an integer, which can lead to
 unexpected results (‘444’ is the same as ‘o674’).  Two other shorthands
 are recognized, ls-style strings like ‘rw-r--r--’, and chmod-style
 permissions like ‘g+w’.  Note that chmod-style permissions are based on
 ‘org-babel-tangle-default-file-mode’, which is ‘#o544’ by default.
 
    When ‘:tangle-mode’ and ‘:shebang’ are both specified, the give
 ‘:tangle-mode’ will override the permissions from ‘:shebang’.  When
 multiple source code blocks tangle to a single file with conflicting
 ‘:tangle-mode’ header arguments, Org’s behavior is undefined.
 
    By default Org expands code blocks during tangling.  The ‘no-expand’
 header argument turns off such expansions.  Note that one side-effect of
 expansion by ‘org-babel-expand-src-block’ also assigns values (see *note
 Environment of a Code Block::) to variables.  Expansions also replace
 noweb references with their targets (see *note Noweb Reference
 Syntax::).  Some of these expansions may cause premature assignment,
 hence this option.  This option makes a difference only for tangling.
 It has no effect when exporting since code blocks for execution have to
 be expanded anyway.
 
 Functions
 ---------
 
 ‘org-babel-tangle’
      Tangle the current file.  Bound to ‘C-c C-v t’.
 
      With prefix argument only tangle the current code block.
 
 ‘org-babel-tangle-file’
      Choose a file to tangle.  Bound to ‘C-c C-v f’.
 
 Tangle hooks
 ------------
 
 ‘org-babel-pre-tangle-hook’
      This hook is run before the tangle process begins.  The active
      buffer is buffer to be tangled.
 
 ‘org-babel-tangle-body-hook’
      This hook is run from a temporary buffer containing expanded code
      of every tangled code block.  The hook can modify the expanded code
      as needed.  The contents of the current buffer will be used as
      actual code block expansion.
 
 ‘org-babel-post-tangle-hook’
      This hook is run from within code files tangled by
      ‘org-babel-tangle’, making it suitable for post-processing,
      compilation, and evaluation of code in the tangled files.
 
 ‘org-babel-tangle-finished-hook’
      This hook is run after post-tangle hooks, in the original buffer.
 
 Jumping between code and Org
 ----------------------------
 
 Debuggers normally link errors and messages back to the source code.
 But for tangled files, we want to link back to the Org file, not to the
 tangled source file.  To make this extra jump, Org uses
 ‘org-babel-tangle-jump-to-org’ function with two additional source code
 block header arguments:
 
   1. Set ‘padline’ to true—this is the default setting.
   2. Set ‘comments’ to ‘link’, which makes Org insert links to the Org
      file.

 16.9 Languages
 ==============
 
 Code blocks in dozens of languages are supported.  See Worg website for
 language specific documentation
 (https://orgmode.org/worg/org-contrib/babel/languages/index.html).
 
    By default, only Emacs Lisp is enabled for evaluation.  To enable or
 disable other languages, customize the ‘org-babel-load-languages’
 variable either through the Emacs customization interface, or by adding
 code to the init file as shown next.
 
    In this example, evaluation is disabled for Emacs Lisp, and enabled
 for R.
 
      (org-babel-do-load-languages
       'org-babel-load-languages
       '((emacs-lisp . nil)
         (R . t)))
 
    Note that this is not the only way to enable a language.  Org also
 enables languages when loaded with ‘require’ statement.  For example,
 the following enables execution of Clojure code blocks:
 
      (require 'ob-clojure)

 16.10 Editing Source Code
 =========================
 
 Use ‘C-c '’ to edit the current code block.  It opens a new major mode
 edit buffer containing the body of the source code block, ready for any
 edits.  Use ‘C-c '’ again to close the buffer and return to the Org
 buffer.
 
    ‘C-x C-s’ saves the buffer and updates the contents of the Org
 buffer.  Set ‘org-edit-src-auto-save-idle-delay’ to save the base buffer
 after a certain idle delay time.  Set ‘org-edit-src-turn-on-auto-save’
 to auto-save this buffer into a separate file using Auto-save mode.
 
    While editing the source code in the major mode, the Org Src minor
 mode remains active.  It provides these customization variables as
 described below.  For even more variables, look in the customization
 group ‘org-edit-structure’.
 
 ‘org-src-lang-modes’
      If an Emacs major-mode named ‘<LANG>-mode’ exists, where <LANG> is
      the language identifier from code block’s header line, then the
      edit buffer uses that major mode.  Use this variable to arbitrarily
      map language identifiers to major modes.
 
      When language identifier is omitted in the src block, Org mode’s
      behavior is undefined.
 
 ‘org-src-window-setup’
      For specifying Emacs window arrangement when the new edit buffer is
      created.
 
 ‘org-src-preserve-indentation’
      Default is ‘nil’.  Source code is indented.  This indentation
      applies during export or tangling, and depending on the context,
      may alter leading spaces and tabs.  When non-‘nil’, source code is
      aligned with the leftmost column.  No lines are modified during
      export or tangling, which is very useful for white-space sensitive
      languages, such as Python.
 
 ‘org-src-ask-before-returning-to-edit-buffer’
      When ‘nil’, Org returns to the edit buffer without further prompts.
      The default prompts for a confirmation.
 
    Fontification of code blocks can give visual separation of text and
 code on the display page.  Set ‘org-src-fontify-natively’ to non-‘nil’
 to turn on native code fontification in the _Org_ buffer.  The
 fontification follows the major mode used to edit the code block (see
 ‘org-src-lang-modes’ above).
 
    To further customize the appearance of ‘org-block’ for specific
 languages, customize ‘org-src-block-faces’.  The following example
 shades the background of regular blocks, and colors source blocks only
 for Python and Emacs Lisp languages.
 
      (require 'color)
      (set-face-attribute 'org-block nil :background
                          (color-darken-name
                           (face-attribute 'default :background) 3))
 
      (setq org-src-block-faces '(("emacs-lisp" (:background "#EEE2FF"))
                                  ("python" (:background "#E5FFB8"))))
 
 
 File: org.info,  Node: Noweb Reference Syntax,  Next: Library of Babel,  Prev: Editing Source Code,  Up: Working with Source Code
 
 16.11 Noweb Reference Syntax
 ============================
 
 Source code blocks can include references to other source code blocks,
 using a noweb(1) style syntax:
 
      <<CODE-BLOCK-ID>>
 
 where CODE-BLOCK-ID refers to either the ‘NAME’ of a single source code
 block, or a collection of one or more source code blocks sharing the
 same ‘noweb-ref’ header argument (see *note Using Header Arguments::).
 Org can replace such references with the source code of the block or
 blocks being referenced, or, in the case of a single source code block
 named with ‘NAME’, with the results of an evaluation of that block.
 
    The ‘noweb’ header argument controls expansion of noweb syntax
 references.  Expansions occur when source code blocks are evaluated,
 tangled, or exported.
 
 ‘no’
      Default.  No expansion of noweb syntax references in the body of
      the code when evaluating, tangling, or exporting.
 
 ‘yes’
      Expansion of noweb syntax references in the body of the code block
      when evaluating, tangling, or exporting.
 
 ‘tangle’
      Expansion of noweb syntax references in the body of the code block
      when tangling.  No expansion when evaluating or exporting.
 
 ‘strip-tangle’
      Expansion of noweb syntax references in the body of the code block
      when evaluating or exporting.  Removes noweb syntax references when
      exporting.
 
 ‘no-export’
      Expansion of noweb syntax references in the body of the code block
      when evaluating or tangling.  No expansion when exporting.
 
 ‘strip-export’
      Expansion of noweb syntax references in the body of the code block
      when expanding prior to evaluating or tangling.  Removes noweb
      syntax references when exporting.
 
 ‘eval’
      Expansion of noweb syntax references in the body of the code block
      only before evaluating.
 
    In the most simple case, the contents of a single source block is
 inserted within other blocks.  Thus, in following example,
 
      #+NAME: initialization
      #+BEGIN_SRC emacs-lisp
        (setq sentence "Never a foot too far, even.")
      #+END_SRC
 
      #+BEGIN_SRC emacs-lisp :noweb yes
        <<initialization>>
        (reverse sentence)
      #+END_SRC
 
 the second code block is expanded as
 
      #+BEGIN_SRC emacs-lisp :noweb yes
        (setq sentence "Never a foot too far, even.")
        (reverse sentence)
      #+END_SRC
 
    Note that noweb expansion does not automatically carry over ‘:var’
 header arguments(2).
 
    You may also include the contents of multiple blocks sharing a common
 ‘noweb-ref’ header argument, which can be set at the file, subtree, or
 code block level.  In the example Org file shown next, the body of the
 source code in each block is extracted for concatenation to a pure code
 file when tangled.
 
      #+BEGIN_SRC sh :tangle yes :noweb yes :shebang #!/bin/sh
        <<fullest-disk>>
      #+END_SRC
      * the mount point of the fullest disk
        :PROPERTIES:
        :header-args: :noweb-ref fullest-disk
        :END:
 
      ** query all mounted disks
      #+BEGIN_SRC sh
        df \
      #+END_SRC
 
      ** strip the header row
      #+BEGIN_SRC sh
        |sed '1d' \
      #+END_SRC
 
      ** output mount point of fullest disk
      #+BEGIN_SRC sh
        |awk '{if (u < +$5) {u = +$5; m = $6}} END {print m}'
      #+END_SRC
 
    By default a newline separates each noweb reference concatenation.
 To use a different separator, edit the ‘noweb-sep’ header argument.
 
    Alternatively, Org can include the results of evaluation of a single
 code block rather than its body [(3).  Evaluation occurs when
 parentheses, possibly including arguments, are appended to the code
 block name, as shown below.
 
      <<NAME(optional arguments)>>
 
    Note that in this case, a code block name set by ‘NAME’ keyword is
 required; the reference set by ‘noweb-ref’ will not work when evaluation
 is desired.
 
    Here is an example that demonstrates how the exported content changes
 when noweb style references are used with parentheses versus without.
 Given:
 
      #+NAME: some-code
      #+BEGIN_SRC python :var num=0 :results output :exports none
      print(num*10)
      #+END_SRC
 
 this code block:
 
      #+BEGIN_SRC text :noweb yes
        <<some-code>>
      #+END_SRC
 
 expands to:
 
      print(num*10)
 
    Below, a similar noweb style reference is used, but with parentheses,
 while setting a variable ‘num’ to 10:
 
      #+BEGIN_SRC text :noweb yes
        <<some-code(num=10)>>
      #+END_SRC
 
 Note that the expansion now contains the results of the code block
 ‘some-code’, not the code block itself:
 
      100
 
    Noweb insertions honor prefix characters that appear before the noweb
 syntax reference.  This behavior is illustrated in the following
 example.  Because the ‘<<example>>’ noweb reference appears behind the
 SQL comment syntax, each line of the expanded noweb reference is
 commented.  With:
 
      #+NAME: example
      #+BEGIN_SRC text
        this is the
        multi-line body of example
      #+END_SRC
 
 this code block:
 
      #+BEGIN_SRC sql :noweb yes
       ---<<example>>
      #+END_SRC
 
 expands to:
 
      #+BEGIN_SRC sql :noweb yes
       ---this is the
       ---multi-line body of example
      #+END_SRC
 
    Since this change does not affect noweb replacement text without
 newlines in them, inline noweb references are acceptable.
 
    This feature can also be used for management of indentation in
 exported code snippets.  With:
 
      #+NAME: if-true
      #+BEGIN_SRC python :exports none
      print('do things when true')
      #+end_src
 
      #+name: if-false
      #+begin_src python :exports none
      print('do things when false')
      #+end_src
 
 this code block:
 
      #+begin_src python :noweb yes :results output
      if true:
          <<if-true>>
      else:
          <<if-false>>
      #+end_src
 
 expands to:
 
      if true:
          print('do things when true')
      else:
          print('do things when false')
 
    This prefix behavior can be turned off in a block by setting the
 ‘noweb-prefix’ header argument to ‘no’, as in:
 
      #+BEGIN_SRC elisp :noweb-prefix no
        (setq example-data "<<example>>")
      #+END_SRC
 
 which expands to:
 
      (setq example-data "this is the
      multi-line body of example")
 
    When in doubt about the outcome of a source code block expansion, you
 can preview the results with the following command:
 
 ‘C-c C-v v’ or ‘C-c C-v C-v’ (‘org-babel-expand-src-block’)
      Expand the current source code block according to its header
      arguments and pop open the results in a preview buffer.
 
    ---------- Footnotes ----------
 
    (1) For noweb literate programming details, see
 <https://www.cs.tufts.edu/~nr/noweb/>.
 
    (2) In the following example, attempting to evaluate the second code
 block will give an error, because the variables defined in the first
 code block will not be defined in the second block.
      #+NAME: get-prompt
      #+BEGIN_SRC emacs-lisp :var prompt="root> " :var command="ls"
        (concat prompt command)
      #+END_SRC
      #+RESULTS: get-prompt
      : root> ls
      #+BEGIN_SRC emacs-lisp :noweb yes
        <<get-prompt>>
      #+END_SRC
    The previous block is expanded without setting ‘prompt’ and ‘command’
 values.
      #+BEGIN_SRC emacs-lisp
        (concat prompt command)
      #+END_SRC
 
    (3) The reference is evaluated with point at the referenced block,
 using its header arguments (including inherited)

 16.12 Library of Babel
 ======================
 
 The “Library of Babel” is a collection of code blocks.  Like a function
 library, these code blocks can be called from other Org files.  A
 collection of useful code blocks is available on Worg
 (https://orgmode.org/worg/library-of-babel.html).  For remote code block
 evaluation syntax, see *note Evaluating Code Blocks::.
 
    For any user to add code to the library, first save the code in
 regular code blocks of an Org file, and then load the Org file with
 ‘org-babel-lob-ingest’, which is bound to ‘C-c C-v i’.

 17.1 Completion
 ===============
 
 Org has in-buffer completions.  Unlike minibuffer completions, which are
 useful for quick command interactions, Org’s in-buffer completions are
 more suitable for content creation in Org documents.  Type one or more
 letters and invoke the hot key to complete the text in-place.  Depending
 on the context and the keys, Org offers different types of completions.
 No minibuffer is involved.  Such mode-specific hot keys have become an
 integral part of Emacs and Org provides several shortcuts.
 
 ‘M-<TAB>’
 
      Complete word at point.
 
         • At the beginning of an empty headline, complete TODO keywords.
 
         • After ‘\’, complete TeX symbols supported by the exporter.
 
         • After ‘:’ in a headline, complete tags.  Org deduces the list
           of tags from the ‘TAGS’ in-buffer option (see *note Setting
           Tags::), the variable ‘org-tag-alist’, or from all tags used
           in the current buffer.
 
         • After ‘:’ and not in a headline, complete property keys.  The
           list of keys is constructed dynamically from all keys used in
           the current buffer.
 
         • After ‘[[’, complete link abbreviations (see *note Link
           Abbreviations::).
 
         • After ‘[[*’, complete headlines in the current buffer so that
           they can be used in search links like: ‘[[*find this
           headline]]’
 
         • After ‘#+’, complete the special keywords like ‘TYP_TODO’ or
           file-specific ‘OPTIONS’.  After option keyword is complete,
           pressing ‘M-<TAB>’ again inserts example settings for this
           keyword.
 
         • After ‘STARTUP’ keyword, complete startup items.
 
         • When point is anywhere else, complete dictionary words using
           Ispell.

 17.2 Structure Templates
 ========================
 
 With just a few keystrokes, it is possible to insert empty structural
 blocks, such as ‘#+BEGIN_SRC’ ... ‘#+END_SRC’, or to wrap existing text
 in such a block.
 
 ‘C-c C-,’ (‘org-insert-structure-template’)
      Prompt for a type of block structure, and insert the block at
      point.  If the region is active, it is wrapped in the block.  First
      prompts the user for keys, which are used to look up a structure
      type from the variable below.  If the key is ‘<TAB>’, ‘<RET>’, or
      ‘<SPC>’, the user is prompted to enter a block type.
 
    Available structure types are defined in
 ‘org-structure-template-alist’, see the docstring for adding or changing
 values.
 
    Org Tempo expands snippets to structures defined in
 ‘org-structure-template-alist’ and ‘org-tempo-keywords-alist’.  For
 example, ‘< s <TAB>’ creates a code block.  Enable it by customizing
 ‘org-modules’ or add ‘(require 'org-tempo)’ to your Emacs init file(1).
 
 ‘a’     ‘#+BEGIN_EXPORT ascii’ ... ‘#+END_EXPORT’
 ‘c’     ‘#+BEGIN_CENTER’ ... ‘#+END_CENTER’
 ‘C’     ‘#+BEGIN_COMMENT’ ... ‘#+END_COMMENT’
 ‘e’     ‘#+BEGIN_EXAMPLE’ ... ‘#+END_EXAMPLE’
 ‘E’     ‘#+BEGIN_EXPORT’ ... ‘#+END_EXPORT’
 ‘h’     ‘#+BEGIN_EXPORT html’ ... ‘#+END_EXPORT’
 ‘l’     ‘#+BEGIN_EXPORT latex’ ... ‘#+END_EXPORT’
 ‘q’     ‘#+BEGIN_QUOTE’ ... ‘#+END_QUOTE’
 ‘s’     ‘#+BEGIN_SRC’ ... ‘#+END_SRC’
 ‘v’     ‘#+BEGIN_VERSE’ ... ‘#+END_VERSE’

 17.3 Speed Keys
 ===============
 
 Single keystrokes can execute custom commands in an Org file when point
 is on a headline.  Without the extra burden of a meta or modifier key,
 Speed Keys can speed navigation or execute custom commands.  Besides
 faster navigation, Speed Keys may come in handy on small mobile devices
 that do not have full keyboards.  Speed Keys may also work on TTY
 devices known for their problems when entering Emacs key chords.
 
    By default, Org has Speed Keys disabled.  To activate Speed Keys, set
 the variable ‘org-use-speed-commands’ to a non-‘nil’ value.  To trigger
 a Speed Key, point must be at the beginning of an Org headline, before
 any of the stars.
 
    Org comes with a pre-defined list of Speed Keys.  To add or modify
 Speed Keys, customize the option ‘org-speed-commands’.  For more
 details, see the variable’s docstring.  With Speed Keys activated, ‘M-x
 org-speed-command-help’, or ‘?’ when point is at the beginning of an Org
 headline, shows currently active Speed Keys, including the user-defined
 ones.

 17.4 A Cleaner Outline View
 ===========================
 
 Org’s outline with stars and no indents can look cluttered for short
 documents.  For _book-like_ long documents, the effect is not as
 noticeable.  Org provides an alternate stars and indentation scheme, as
 shown on the right in the following table.  It displays only one star
 and indents text to line up with the heading:
 
      * Top level headline             |    * Top level headline

      *** Third level                  |        * Third level
      some text                        |          some text

      * Another top level headline     |    * Another top level headline
 
    Org can achieve this in two ways, (1) by just displaying the buffer
 in this way without changing it, or (2) by actually indenting every line
 in the desired amount with hard spaces and hiding leading stars.

 17.4.1 Org Indent Mode
 ----------------------
 
 To display the buffer in the indented view, activate Org Indent minor
 mode, using ‘M-x org-indent-mode’.  Text lines that are not headlines
 are prefixed with virtual spaces to vertically align with the headline
 text(1).
 
    To make more horizontal space, the headlines are shifted by two
 characters.  Configure ‘org-indent-indentation-per-level’ variable for a
 different number.
 
    By default, Org Indent mode turns off ‘org-adapt-indentation’ and
 does hide leading stars by locally setting ‘org-hide-leading-stars’ to
 ‘t’: only one star on each headline is visible, the rest are masked with
 the same font color as the background.  If you want to customize this
 default behavior, see ‘org-indent-mode-turns-on-hiding-stars’ and
 ‘org-indent-mode-turns-off-org-adapt-indentation’.
 
    To globally turn on Org Indent mode for all files, customize the
 variable ‘org-startup-indented’.  To control it for individual files,
 use ‘STARTUP’ keyword as follows:
 
      #+STARTUP: indent
      #+STARTUP: noindent
 
    ---------- Footnotes ----------
 
    (1) Org Indent mode also sets ‘wrap-prefix’ correctly for indenting
 and wrapping long lines of headlines or text.  This minor mode also
 handles Visual Line mode and directly applied settings through
 ‘word-wrap’.
 
 
 File: org.info,  Node: Hard indentation,  Prev: Org Indent Mode,  Up: Clean View
 
 17.4.2 Hard indentation
 -----------------------
 
 It is possible to use hard spaces to achieve the indentation instead, if
 the bare ASCII file should have the indented look also outside Emacs(1).
 With Org’s support, you have to indent all lines to line up with the
 outline headers.  You would use these settings(2):
 
      (setq org-adapt-indentation t
            org-hide-leading-stars t
            org-odd-levels-only t)
 
 _Indentation of text below headlines_ (‘org-adapt-indentation’)
      The first setting modifies paragraph filling, line wrapping, and
      structure editing commands to preserving or adapting the
      indentation as appropriate.
 
 _Hiding leading stars_ (‘org-hide-leading-stars’)
      The second setting makes leading stars invisible by applying the
      face ‘org-hide’ to them.  For per-file preference, use these file
      ‘STARTUP’ options:
 
           #+STARTUP: hidestars
           #+STARTUP: showstars
 
 _Odd levels_ (‘org-odd-levels-only’)
      The third setting makes Org use only odd levels, 1, 3, 5, ..., in
      the outline to create more indentation.  On a per-file level,
      control this with:
 
           #+STARTUP: odd
           #+STARTUP: oddeven
 
      To convert a file between single and double stars layouts, use ‘M-x
      org-convert-to-odd-levels’ and ‘M-x org-convert-to-oddeven-levels’.
 
    ---------- Footnotes ----------
 
    (1) This works, but requires extra effort.  Org Indent mode is more
 convenient for most applications.
 
    (2) ‘org-adapt-indentation’ can also be set to ‘'headline-data’, in
 which case only data lines below the headline will be indented.

 17.5 Execute commands in the active region
 ==========================================
 
 When in an Org buffer and the region is active, some commands will apply
 to all the subtrees in the active region.  For example, hitting ‘C-c
 C-s’ when multiple headlines are within the active region will
 successively prompt you for a new schedule date and time.  To disable
 this, set the option ‘org-loop-over-headlines-in-active-region’ to
 non-‘t’, activate the region and run the command normally.
 
    ‘org-agenda-loop-over-headlines-in-active-region’ is the equivalent
 option of the agenda buffer, where you can also use *note bulk editing
 of selected entries: Bulk remote editing selected entries.
 
    Not all commands can loop in the active region and what subtrees or
 headlines are considered can be refined: see the docstrings of these
 options for more details.

 17.6 Dynamic Headline Numbering
 ===============================
 
 The Org Num minor mode, toggled with ‘M-x org-num-mode’, displays
 outline numbering on top of headlines.  It also updates it automatically
 upon changes to the structure of the document.
 
    By default, all headlines are numbered.  You can limit numbering to
 specific headlines according to their level, tags, ‘COMMENT’ keyword, or
 ‘UNNUMBERED’ property.  Set ‘org-num-max-level’, ‘org-num-skip-tags’,
 ‘org-num-skip-commented’, ‘org-num-skip-unnumbered’, or
 ‘org-num-skip-footnotes’ accordingly.
 
    If ‘org-num-skip-footnotes’ is non-‘nil’, footnotes sections (see
 *note Creating Footnotes::) are not numbered either.
 
    You can control how the numbering is displayed by setting
 ‘org-num-face’ and ‘org-num-format-function’.
 
    You can also turn this mode globally for all Org files by setting the
 option ‘org-startup-numerated’ to ‘t’, or locally on a file by using
 ‘#+startup: num’.

 17.7 The Very Busy ‘C-c C-c’ Key
 ================================
 
 The ‘C-c C-c’ key in Org serves many purposes depending on the context.
 It is probably the most over-worked, multi-purpose key combination in
 Org.  Its uses are well documented throughout this manual, but here is a
 consolidated list for easy reference.
 
    • If column view (see *note Column View::) is on, exit column view.
 
    • If any highlights shown in the buffer from the creation of a sparse
      tree, or from clock display, remove such highlights.
 
    • If point is in one of the special ‘KEYWORD’ lines, scan the buffer
      for these lines and update the information.  Also reset the Org
      file cache used to temporary store the contents of URLs used as
      values for keywords like ‘SETUPFILE’.
 
    • If point is inside a table, realign the table.
 
    • If point is on a ‘TBLFM’ keyword, re-apply the formulas to the
      entire table.
 
    • If the current buffer is a capture buffer, close the note and file
      it.  With a prefix argument, also jump to the target location after
      saving the note.
 
    • If point is on a ‘<<<target>>>’, update radio targets and
      corresponding links in this buffer.
 
    • If point is on a property line or at the start or end of a property
      drawer, offer property commands.
 
    • If point is at a footnote reference, go to the corresponding
      definition, and _vice versa_.
 
    • If point is on a statistics cookie, update it.
 
    • If point is in a plain list item with a checkbox, toggle the status
      of the checkbox.
 
    • If point is on a numbered item in a plain list, renumber the
      ordered list.
 
    • If point is on the ‘#+BEGIN’ line of a dynamic block, the block is
      updated.
 
    • If point is at a timestamp, fix the day name in the timestamp.

 17.8 Summary of In-Buffer Settings
 ==================================
 
 In-buffer settings start with ‘#+’, followed by a keyword, a colon, one
 or more spaces, and then a word for each setting.  Org accepts multiple
 settings on the same line.  Org also accepts multiple lines for a
 keyword.  This manual describes these settings throughout.  A summary
 follows here.
 
    ‘C-c C-c’ activates any changes to the in-buffer settings.  Closing
 and reopening the Org file in Emacs also activates the changes.
 
 ‘#+ARCHIVE: %s_done::’
      Sets the archive location of the agenda file.  The corresponding
      variable is ‘org-archive-location’.
 
 ‘#+CATEGORY’
      Sets the category of the agenda file, which applies to the entire
      document.
 
 ‘#+COLUMNS: %25ITEM ...’
      Set the default format for columns view.  This format applies when
      columns view is invoked in locations where no ‘COLUMNS’ property
      applies.
 
 ‘#+CONSTANTS: name1=value1 ...’
      Set file-local values for constants that table formulas can use.
      This line sets the local variable
      ‘org-table-formula-constants-local’.  The global version of this
      variable is ‘org-table-formula-constants’.
 
 ‘#+FILETAGS: :tag1:tag2:tag3:’
      Set tags that all entries in the file inherit from, including the
      top-level entries.
 
 ‘#+LINK: linkword replace’
      Each line specifies one abbreviation for one link.  Use multiple
      ‘LINK’ keywords for more, see *note Link Abbreviations::.  The
      corresponding variable is ‘org-link-abbrev-alist’.
 
 ‘#+PRIORITIES: highest lowest default’
      This line sets the limits and the default for the priorities.  All
      three must be either letters A–Z or numbers 0–9.  The highest
      priority must have a lower ASCII number than the lowest priority.
 
 ‘#+PROPERTY: Property_Name Value’
      This line sets a default inheritance value for entries in the
      current buffer, most useful for specifying the allowed values of a
      property.
 
 ‘#+SETUPFILE: file’
      The setup file or a URL pointing to such file is for additional
      in-buffer settings.  Org loads this file and parses it for any
      settings in it when Org opens the main file.  If URL is specified,
      the contents are downloaded and stored in a temporary file cache.
      ‘C-c C-c’ on the settings line re-parses and re-loads the file, and
      also resets the temporary file cache.
 
      Org also parses and loads _in-buffer settings_ from the setup file
      during normal exporting process.  Org parses the _in-buffer
      settings_ as if it was included in the containing Org buffer.  The
      rest of the contents of setup file is ignored.
 
      To visit the setup file—not a URL—use ‘C-c '’ while point is on the
      line with the setup file name.
 
 ‘#+STARTUP:’
      Startup options Org uses when first visiting a file.
 
      The first set of options deals with the initial visibility of the
      outline tree.  The corresponding variable for global default
      settings is ‘org-startup-folded’ with a default value of
      ‘showeverything’.
 
      ‘overview’         Top-level headlines only.
      ‘content’          All headlines.
      ‘showall’          No folding on any entry.
      ‘show2levels’      Headline levels 1-2.
      ‘show3levels’      Headline levels 1-3.
      ‘show4levels’      Headline levels 1-4.
      ‘show5levels’      Headline levels 1-5.
      ‘showeverything’   Show even drawer contents.
 
      Dynamic virtual indentation is controlled by the variable
      ‘org-startup-indented’(1).
 
      ‘indent’     Start with Org Indent mode turned on.
      ‘noindent’   Start with Org Indent mode turned off.
 
      Dynamic virtual numeration of headlines is controlled by the
      variable ‘org-startup-numerated’.
 
      ‘num’     Start with Org num mode turned on.
      ‘nonum’   Start with Org num mode turned off.
 
      Aligns tables consistently upon visiting a file.  The corresponding
      variable is ‘org-startup-align-all-tables’ with ‘nil’ as default
      value.
 
      ‘align’     Align all tables.
      ‘noalign’   Do not align tables on startup.
 
      Shrink table columns with a width cookie.  The corresponding
      variable is ‘org-startup-shrink-all-tables’ with ‘nil’ as default
      value.
 
      When visiting a file, inline images can be automatically displayed.
      The corresponding variable is ‘org-startup-with-inline-images’,
      with a default value ‘nil’ to avoid delays when visiting a file.
 
      ‘inlineimages’     Show inline images.
      ‘noinlineimages’   Do not show inline images on startup.
 
      Bracket links in Org buffers are displayed hiding the link path and
      brackets.  For example, ‘[[https://orgmode.org][Org Website]]’ is,
      by default, displayed as “Org Website”, hiding the link itself and
      just displaying its description.  Alternatively, the links can be
      displayed in full.  The corresponding variable is
      ‘org-link-descriptive’.
 
      ‘descriptivelinks’   Hide path and brackets in links.
      ‘literallinks’       Do not hide anything.
 
      Logging the closing and reopening of TODO items and clock intervals
      can be configured using these options (see variables
      ‘org-log-done’, ‘org-log-note-clock-out’, and ‘org-log-repeat’).
 
      ‘logdone’              Record a timestamp when an item is marked as done.
      ‘lognotedone’          Record timestamp and a note when DONE.
      ‘nologdone’            Do not record when items are marked as done.
      ‘logrepeat’            Record a time when reinstating a repeating item.
      ‘lognoterepeat’        Record a note when reinstating a repeating item.
      ‘nologrepeat’          Do not record when reinstating repeating item.
      ‘lognoteclock-out’     Record a note when clocking out.
      ‘nolognoteclock-out’   Do not record a note when clocking out.
      ‘logreschedule’        Record a timestamp when scheduling time changes.
      ‘lognotereschedule’    Record a note when scheduling time changes.
      ‘nologreschedule’      Do not record when a scheduling date changes.
      ‘logredeadline’        Record a timestamp when deadline changes.
      ‘lognoteredeadline’    Record a note when deadline changes.
      ‘nologredeadline’      Do not record when a deadline date changes.
      ‘logrefile’            Record a timestamp when refiling.
      ‘lognoterefile’        Record a note when refiling.
      ‘nologrefile’          Do not record when refiling.
 
      Here are the options for hiding leading stars in outline headings,
      and for indenting outlines.  The corresponding variables are
      ‘org-hide-leading-stars’ and ‘org-odd-levels-only’, both with a
      default setting ‘nil’ (meaning ‘showstars’ and ‘oddeven’).
 
      ‘hidestars’   Make all but one of the stars starting a headline invisible.
      ‘showstars’   Show all stars starting a headline.
      ‘indent’      Virtual indentation according to outline level.
      ‘noindent’    No virtual indentation according to outline level.
      ‘odd’         Allow only odd outline levels (1, 3, ...).
      ‘oddeven’     Allow all outline levels.
 
      To turn on custom format overlays over timestamps (variables
      ‘org-display-custom-times’ and ‘org-timestamp-custom-formats’),
      use:
 
      ‘customtime’   Overlay custom time format.
 
      The following options influence the table spreadsheet (variable
      ‘constants-unit-system’).
 
      ‘constcgs’   ‘constants.el’ should use the c-g-s unit system.
      ‘constSI’    ‘constants.el’ should use the SI unit system.
 
      To influence footnote settings, use the following keywords.  The
      corresponding variables are ‘org-footnote-define-inline’,
      ‘org-footnote-auto-label’, and ‘org-footnote-auto-adjust’.
 
      ‘fninline’     Define footnotes inline.
      ‘fnnoinline’   Define footnotes in separate section.
      ‘fnlocal’      Define footnotes near first reference, but not inline.
      ‘fnprompt’     Prompt for footnote labels.
      ‘fnauto’       Create ‘[fn:1]’-like labels automatically (default).
      ‘fnconfirm’    Offer automatic label for editing or confirmation.
      ‘fnadjust’     Automatically renumber and sort footnotes.
      ‘nofnadjust’   Do not renumber and sort automatically.
      ‘fnanon’       Create anonymous footnotes with ‘org-footnote-new’.
 
      To hide blocks or drawers on startup, use these keywords.  The
      corresponding variables are ‘org-hide-block-startup’ and
      ‘org-hide-drawer-startup’.
 
      ‘hideblocks’      Hide all begin/end blocks on startup.
      ‘nohideblocks’    Do not hide blocks on startup.
      ‘hidedrawers’     Hide all begin/end blocks on startup.
      ‘nohidedrawers’   Do not hide blocks on startup.
 
    The display of entities as UTF-8 characters is governed by the
 variable ‘org-pretty-entities’ and the keywords
 
 ‘entitiespretty’   Show entities as UTF-8 characters where possible.
 ‘entitiesplain’    Leave entities plain.
 
 ‘#+TAGS: TAG1(c1) TAG2(c2)’
      These lines (several such lines are allowed) specify the valid tags
      in this file, and (potentially) the corresponding _fast tag
      selection_ keys.  The corresponding variable is ‘org-tag-alist’.
 
 ‘#+TODO:’, ‘#+SEQ_TODO:’, ‘#+TYP_TODO:’
      These lines set the TODO keywords and their interpretation in the
      current file.  The corresponding variable is ‘org-todo-keywords’.
 
    ---------- Footnotes ----------
 
    (1) Note that Org Indent mode also sets the ‘wrap-prefix’ property,
 such that Visual Line mode (or purely setting ‘word-wrap’) wraps long
 lines, including headlines, correctly indented.

 17.9 Regular Expressions
 ========================
 
 Org, as an Emacs mode, makes use of Elisp regular expressions for
 searching, matching and filtering.  Elisp regular expressions have a
 somewhat different syntax then some common standards.  Most notably,
 alternation is indicated using ‘\|’ and matching groups are denoted by
 ‘\(...\)’.  For example the string ‘home\|work’ matches either ‘home’ or
 ‘work’.
 
    For more information, see *note Regular Expressions in Emacs:
 (emacs)Regexps.
 
 
 File: org.info,  Node: Org Syntax,  Next: Documentation Access,  Prev: Regular Expressions,  Up: Miscellaneous
 
 17.10 Org Syntax
 ================
 
 A reference document providing a formal description of Org’s syntax is
 available as a draft on Worg (https://orgmode.org/worg/org-syntax.html),
 initially written by Nicolas Goaziou.  It defines Org’s core internal
 concepts such as “headlines”, “sections”, “affiliated keywords”,
 “(greater) elements” and “objects”.  Each part of an Org document
 belongs to one of the previous categories.
 
    To explore the abstract structure of an Org buffer, run this in a
 buffer:
 
      M-: (org-element-parse-buffer) <RET>
 
 It outputs a list containing the buffer’s content represented as an
 abstract structure.  The export engine relies on the information stored
 in this list.  Most interactive commands—e.g., for structure
 editing—also rely on the syntactic meaning of the surrounding context.
 
    You can probe the syntax of your documents with the command
 
      M-x org-lint <RET>
 
 It runs a number of checks to find common mistakes.  It then displays
 their location in a dedicated buffer, along with a description and a
 “trust level”, since false-positive are possible.  From there, you can
 operate on the reports with the following keys:
 
 ‘C-j’, ‘<TAB>’   Display the offending line
 ‘<RET>’          Move point to the offending line
 ‘g’              Check the document again
 ‘h’              Hide all reports from the same checker
 ‘i’              Also remove them from all subsequent checks
 ‘S’              Sort reports by the column at point

 17.11 Context Dependent Documentation
 =====================================
 
 ‘C-c C-x I’ in an Org file tries to open a suitable section of the Org
 manual depending on the syntax at point.  For example, using it on a
 headline displays “Document Structure” section.
 
    ‘q’ closes the Info window.
 
 
 File: org.info,  Node: Escape Character,  Next: Code Evaluation Security,  Prev: Documentation Access,  Up: Miscellaneous
 
 17.12 Escape Character
 ======================
 
 You may sometimes want to write text that looks like Org syntax, but
 should really read as plain text.  Org may use a specific escape
 character in some situations, i.e., a backslash in macros (see *note
 Macro Replacement::) and links (see *note Link Format::), or a comma in
 source and example blocks (see *note Literal Examples::).  In the
 general case, however, we suggest to use the zero width space.  You can
 insert one with any of the following:
 
      C-x 8 <RET> zero width space <RET>
      C-x 8 <RET> 200B <RET>
 
    For example, in order to write ‘[[1,2]]’ as-is in your document, you
 may write instead
 
      [X[1,2]]
 
    where ‘X’ denotes the zero width space character.

 17.13 Code Evaluation and Security Issues
 =========================================
 
 Unlike plain text, running code comes with risk.  Each source code
 block, in terms of risk, is equivalent to an executable file.  Org
 therefore puts a few confirmation prompts by default.  This is to alert
 the casual user from accidentally running untrusted code.
 
    For users who do not run code blocks or write code regularly, Org’s
 default settings should suffice.  However, some users may want to tweak
 the prompts for fewer interruptions.  To weigh the risks of automatic
 execution of code blocks, here are some details about code evaluation.
 
    Org evaluates code in the following circumstances:
 
 _Source code blocks_
      Org evaluates source code blocks in an Org file during export.  Org
      also evaluates a source code block with the ‘C-c C-c’ key chord.
      Users exporting or running code blocks must load files only from
      trusted sources.  Be wary of customizing variables that remove or
      alter default security measures.
 
       -- User Option: org-confirm-babel-evaluate
           When ‘t’, Org prompts the user for confirmation before
           executing each code block.  When ‘nil’, Org executes code
           blocks without prompting the user for confirmation.  When this
           option is set to a custom function, Org invokes the function
           with these two arguments: the source code language and the
           body of the code block.  The custom function must return
           either a ‘t’ or ‘nil’, which determines if the user is
           prompted.  Each source code language can be handled separately
           through this function argument.
 
      For example, here is how to execute ditaa code blocks without
      prompting:
 
           (defun my-org-confirm-babel-evaluate (lang body)
             (not (string= lang "ditaa")))  ;don't ask for ditaa
           (setq org-confirm-babel-evaluate #'my-org-confirm-babel-evaluate)
 
 _Following ‘shell’ and ‘elisp’ links_
      Org has two link types that can directly evaluate code (see *note
      External Links::).  Because such code is not visible, these links
      have a potential risk.  Org therefore prompts the user when it
      encounters such links.  The customization variables are:
 
       -- User Option: org-link-shell-confirm-function
           Function that prompts the user before executing a shell link.
 
       -- User Option: org-link-elisp-confirm-function
           Function that prompts the user before executing an Emacs Lisp
           link.
 
 _Formulas in tables_
      Formulas in tables (see *note The Spreadsheet::) are code that is
      evaluated either by the Calc interpreter, or by the Emacs Lisp
      interpreter.

 17.14.1 Packages that Org cooperates with
 -----------------------------------------
 
 ‘calc.el’ by Dave Gillespie
 
      Org uses the Calc package for implementing spreadsheet
      functionality in its tables (see *note The Spreadsheet::).  Org
      also uses Calc for embedded calculations.  See *note GNU Emacs Calc
      Manual: (calc)Embedded Mode.
 
 ‘constants.el’ by Carsten Dominik
 
      Org can use names for constants in formulas in tables.  Org can
      also use calculation suffixes for units, such as ‘M’ for ‘Mega’.
      For a standard collection of such constants, install the
      ‘constants’ package.  Install version 2.0 of this package,
      available at <https://github.com/cdominik/constants-for-Emacs>.
      Org checks if the function ‘constants-get’ has been autoloaded.
      Installation instructions are in the file ‘constants.el’.
 
 ‘cdlatex.el’ by Carsten Dominik
 
      Org mode can make use of the CDLaTeX package to efficiently enter
      LaTeX fragments into Org files.  See *note CDLaTeX mode::.
 
 ‘imenu.el’ by Ake Stenhoff and Lars Lindberg
 
      Imenu creates dynamic menus based on an index of items in a file.
      Org mode supports Imenu menus.  Enable it with a mode hook as
      follows:
 
           (add-hook 'org-mode-hook
                     (lambda () (imenu-add-to-menubar "Imenu")))
 
      By default the index is two levels deep—you can modify the depth
      using the option ‘org-imenu-depth’.
 
      Org activates Imenu support only in the buffers opened after
      loading Imenu library.  To enable Imenu support in an already
      opened Org buffer, reload Org.
 
 ‘speedbar.el’ by Eric M. Ludlam
 
      Speedbar package creates a special Emacs frame for displaying files
      and index items in files.  Org mode supports Speedbar; users can
      drill into Org files directly from the Speedbar.  The ‘<’ in the
      Speedbar frame tweaks the agenda commands to that file or to a
      subtree.
 
 ‘table.el’ by Takaaki Ota
 
      Complex ASCII tables with automatic line wrapping, column- and
      row-spanning, and alignment can be created using the Emacs table
      package by Takaaki Ota.  Org mode recognizes such tables and
      exports them properly.  ‘C-c '’ to edit these tables in a special
      buffer, much like Org’s code blocks.  Because of interference with
      other Org mode functionality, Takaaki Ota tables cannot be edited
      directly in the Org buffer.
 
      ‘C-c '’ (‘org-edit-special’)
           Edit a ‘table.el’ table.  Works when point is in a ‘table.el’
           table.
 
      ‘C-c ~​’ (‘org-table-create-with-table.el’)
           Insert a ‘table.el’ table.  If there is already a table at
           point, this command converts it between the ‘table.el’ format
           and the Org mode format.  See the documentation string of the
           command ‘org-convert-table’ for the restrictions under which
           this is possible.

 17.14.2 Packages that conflict with Org mode
 --------------------------------------------
 
 In Emacs, shift-selection combines motions of point with shift key to
 enlarge regions.  Emacs sets this mode by default.  This conflicts with
 Org’s use of ‘S-<cursor>’ commands to change timestamps, TODO keywords,
 priorities, and item bullet types, etc.  Since ‘S-<cursor>’ commands
 outside of specific contexts do not do anything, Org offers the variable
 ‘org-support-shift-select’ for customization.  Org mode accommodates
 shift selection by (i) making it available outside of the special
 contexts where special commands apply, and (ii) extending an existing
 active region even if point moves across a special context.
 
 ‘cua.el’ by Kim F. Storm
      Org key bindings conflict with ‘S-<cursor>’ keys used by CUA mode.
      For Org to relinquish these bindings to CUA mode, configure the
      variable ‘org-replace-disputed-keys’.  When set, Org moves the
      following key bindings in Org files, and in the agenda buffer—but
      not during date selection.
 
      ‘S-<UP>’ ⇒ ‘M-p’              ‘S-<DOWN>’ ⇒ ‘M-n’
      ‘S-<LEFT>’ ⇒ ‘M--’            ‘S-<RIGHT>’ ⇒ ‘M-+’
      ‘C-S-<LEFT>’ ⇒ ‘M-S--’        ‘C-S-<RIGHT>’ ⇒ ‘M-S-+’
 
      Yes, these are unfortunately more difficult to remember.  If you
      want to have other replacement keys, look at the variable
      ‘org-disputed-keys’.
 
 ‘ecomplete.el’ by Lars Magne Ingebrigtsen
      Ecomplete provides “electric” address completion in address header
      lines in message buffers.  Sadly Orgtbl mode cuts Ecomplete’s power
      supply: no completion happens when Orgtbl mode is enabled in
      message buffers while entering text in address header lines.  If
      one wants to use ecomplete one should _not_ follow the advice to
      automagically turn on Orgtbl mode in message buffers (see *note
      Orgtbl Mode::), but instead—after filling in the message
      headers—turn on Orgtbl mode manually when needed in the messages
      body.
 
 ‘filladapt.el’ by Kyle Jones
      Org mode tries to do the right thing when filling paragraphs, list
      items and other elements.  Many users reported problems using both
      ‘filladapt.el’ and Org mode, so a safe thing to do is to disable
      filladapt like this:
 
           (add-hook 'org-mode-hook 'turn-off-filladapt-mode)
 
 ‘viper.el’ by Michael Kifer
 
      Viper uses ‘C-c /’ and therefore makes this key not access the
      corresponding Org mode command ‘org-sparse-tree’.  You need to find
      another key for this command, or override the key in
      ‘viper-vi-global-user-map’ with
 
           (define-key viper-vi-global-user-map "C-c /" 'org-sparse-tree)
 
 ‘windmove.el’ by Hovav Shacham
 
      This package also uses the ‘S-<cursor>’ keys, so everything written
      in the paragraph above about CUA mode also applies here.  If you
      want to make the windmove function active in locations where Org
      mode does not have special functionality on ‘S-<cursor>’, add this
      to your configuration:
 
           ;; Make windmove work in Org mode:
           (add-hook 'org-shiftup-final-hook 'windmove-up)
           (add-hook 'org-shiftleft-final-hook 'windmove-left)
           (add-hook 'org-shiftdown-final-hook 'windmove-down)
           (add-hook 'org-shiftright-final-hook 'windmove-right)
 
 ‘yasnippet.el’
      The way Org mode binds the ‘<TAB>’ key (binding to ‘[tab]’ instead
      of ‘"\t"’) overrules YASnippet’s access to this key.  The following
      code fixed this problem:
 
           (add-hook 'org-mode-hook
                     (lambda ()
                       (setq-local yas/trigger-key [tab])
                       (define-key yas/keymap [tab] 'yas/next-field-or-maybe-expand)))
 
      The latest version of YASnippet does not play well with Org mode.
      If the above code does not fix the conflict, start by defining the
      following function:
 
           (defun yas/org-very-safe-expand ()
             (let ((yas/fallback-behavior 'return-nil)) (yas/expand)))
 
      Then, tell Org mode to use that function:
 
           (add-hook 'org-mode-hook
                     (lambda ()
                       (make-variable-buffer-local 'yas/trigger-key)
                       (setq yas/trigger-key [tab])
                       (add-to-list 'org-tab-first-hook 'yas/org-very-safe-expand)
                       (define-key yas/keymap [tab] 'yas/next-field)))

 17.15 Using Org on a TTY
 ========================
 
 Org provides alternative key bindings for TTY and modern mobile devices
 that cannot perform movement commands on point and key bindings with
 modifier keys.  Some of these workarounds may be more cumbersome than
 necessary.  Users should look into customizing these further based on
 their usage needs.  For example, the normal ‘S-<cursor>’ for editing
 timestamp might be better with ‘C-c .’ chord.
 
 Default        Alternative 1        Speed key   Alternative 2
 ----------------------------------------------------------------
 ‘S-<TAB>’      ‘C-u <TAB>’          ‘C’
 ‘M-<LEFT>’     ‘C-c C-x l’          ‘l’         ‘Esc <LEFT>’
 ‘M-S-<LEFT>’   ‘C-c C-x L’          ‘L’
 ‘M-<RIGHT>’    ‘C-c C-x r’          ‘r’         ‘Esc <RIGHT>’
 ‘M-S-<RIGHT>’  ‘C-c C-x R’          ‘R’
 ‘M-<UP>’       ‘C-c C-x u’                      ‘Esc <UP>’
 ‘M-S-<UP>’     ‘C-c C-x U’          ‘U’
 ‘M-<DOWN>’     ‘C-c C-x d’                      ‘Esc <DOWN>’
 ‘M-S-<DOWN>’   ‘C-c C-x D’          ‘D’
 ‘S-<RET>’      ‘C-c C-x c’
 ‘M-<RET>’      ‘C-c C-x m’                      ‘Esc <RET>’
 ‘M-S-<RET>’    ‘C-c C-x M’
 ‘S-<LEFT>’     ‘C-c <LEFT>’
 ‘S-<RIGHT>’    ‘C-c <RIGHT>’
 ‘S-<UP>’       ‘C-c <UP>’
 ‘S-<DOWN>’     ‘C-c <DOWN>’
 ‘C-S-<LEFT>’   ‘C-c C-x <LEFT>’

 17.16 Protocols for External Access
 ===================================
 
 Org protocol is a tool to trigger custom actions in Emacs from external
 applications.  Any application that supports calling external programs
 with an URL as argument may be used with this functionality.  For
 example, you can configure bookmarks in your web browser to send a link
 to the current page to Org and create a note from it using capture (see
 *note Capture::).  You can also create a bookmark that tells Emacs to
 open the local source file of a remote website you are browsing.
 
    In order to use Org protocol from an application, you need to
 register ‘org-protocol://’ as a valid scheme-handler.  External calls
 are passed to Emacs through the ‘emacsclient’ command, so you also need
 to ensure an Emacs server is running.  More precisely, when the
 application calls
 
      emacsclient "org-protocol://PROTOCOL?key1=val1&key2=val2"
 
 Emacs calls the handler associated to PROTOCOL with argument ‘(:key1
 val1 :key2 val2)’.
 
    Org protocol comes with three predefined protocols, detailed in the
 following sections.  Configure ‘org-protocol-protocol-alist’ to define
 your own.
 
 * Menu:
 
 * The store-link protocol:: Store a link, push URL to kill-ring.
 * The capture protocol::  Fill a buffer with external information.
 * The open-source protocol:: Edit published contents.
 
 
 File: org.info,  Node: The store-link protocol,  Next: The capture protocol,  Up: Protocols
 
 17.16.1 The ‘store-link’ protocol
 ---------------------------------
 
 Using the ‘store-link’ handler, you can copy links, to that they can be
 inserted using ‘M-x org-insert-link’ or yanking.  More precisely, the
 command
 
      emacsclient "org-protocol://store-link?url=URL&title=TITLE"
 
 stores the following link:
 
      [[URL][TITLE]]
 
    In addition, URL is pushed on the kill-ring for yanking.  You need to
 encode URL and TITLE if they contain slashes, and probably quote those
 for the shell.
 
    To use this feature from a browser, add a bookmark with an arbitrary
 name, e.g., ‘Org: store-link’ and enter this as _Location_:
 
      javascript:location.href='org-protocol://store-link?' +
            new URLSearchParams({url:location.href, title:document.title});
 
    Title is an optional parameter.  Another expression was recommended
 earlier:
 
      javascript:location.href='org-protocol://store-link?url='+
            encodeURIComponent(location.href);
 
    The latter form is compatible with older Org versions from 9.0 to
 9.4.
 
 
 File: org.info,  Node: The capture protocol,  Next: The open-source protocol,  Prev: The store-link protocol,  Up: Protocols
 
 17.16.2 The ‘capture’ protocol
 ------------------------------
 
 Activating the “capture” handler pops up a ‘Capture’ buffer in Emacs,
 using acapture template.
 
      emacsclient "org-protocol://capture?template=X&url=URL&title=TITLE&body=BODY"
 
    To use this feature, add a bookmark with an arbitrary name, e.g.,
 ‘Org: capture’, and enter this as ‘Location’:
 
      javascript:location.href='org-protocol://capture?' +
            new URLSearchParams({
                  template: 'x', url: window.location.href,
                  title: document.title, body: window.getSelection()});
 
    You might have seen another expression:
 
      javascript:location.href='org-protocol://capture?template=x'+
            '&url='+encodeURIComponent(window.location.href)+
            '&title='+encodeURIComponent(document.title)+
            '&body='+encodeURIComponent(window.getSelection());
 
    It is a bit more cluttered than the former one, but it is compatible
 with previous Org versions 9.0-9.4.  In these versions encoding of space
 as “+” character was not supported by URI decoder.
 
    The capture template to be used can be specified in the bookmark
 (like ‘X’ above).  If unspecified, the template key is set in the
 variable ‘org-protocol-default-template-key’.  The following template
 placeholders are available:
 
      %:link          The URL
      %:description   The webpage title
      %:annotation    Equivalent to [[%:link][%:description]]
      %i              The selected text
 
 
 File: org.info,  Node: The open-source protocol,  Prev: The capture protocol,  Up: Protocols
 
 17.16.3 The ‘open-source’ protocol
 ----------------------------------
 
 The ‘open-source’ handler is designed to help with editing local sources
 when reading a document.  To that effect, you can use a bookmark with
 the following location:
 
      javascript:location.href='org-protocol://open-source?&url='+
            encodeURIComponent(location.href)
 
    The variable ‘org-protocol-project-alist’ maps URLs to local file
 names, by stripping URL parameters from the end and replacing the
 ‘:base-url’ with ‘:working-directory’ and ‘:online-suffix’ with
 ‘:working-suffix’.  For example, assuming you own a local copy of
 ‘https://orgmode.org/worg/’ contents at ‘/home/user/worg’, you can set
 ‘org-protocol-project-alist’ to the following
 
      (setq org-protocol-project-alist
            '(("Worg"
               :base-url "https://orgmode.org/worg/"
               :working-directory "/home/user/worg/"
               :online-suffix ".html"
               :working-suffix ".org")))
 
 If you are now browsing
 ‘https://orgmode.org/worg/org-contrib/org-protocol.html’ and find a typo
 or have an idea about how to enhance the documentation, simply click the
 bookmark and start editing.
 
    However, such mapping may not always yield the desired results.
 Suppose you maintain an online store located at ‘https://example.com/’.
 The local sources reside in ‘/home/user/example/’.  It is common
 practice to serve all products in such a store through one file and
 rewrite URLs that do not match an existing file on the server.  That
 way, a request to ‘https://example.com/print/posters.html’ might be
 rewritten on the server to something like
 ‘https://example.com/shop/products.php/posters.html.php’.  The
 ‘open-source’ handler probably cannot find a file named
 ‘/home/user/example/print/posters.html.php’ and fails.
 
    Such an entry in ‘org-protocol-project-alist’ may hold an additional
 property ‘:rewrites’.  This property is a list of cons cells, each of
 which maps a regular expression to a path relative to the
 ‘:working-directory’.
 
    Now map the URL to the path ‘/home/user/example/products.php’ by
 adding ‘:rewrites’ rules like this:
 
      (setq org-protocol-project-alist
            '(("example.com"
               :base-url "https://example.com/"
               :working-directory "/home/user/example/"
               :online-suffix ".php"
               :working-suffix ".php"
               :rewrites (("example.com/print/" . "products.php")
                          ("example.com/$" . "index.php")))))
 
 Since ‘example.com/$’ is used as a regular expression, it maps
 ‘https://example.com/’, ‘https://example.com’,
 ‘https://www.example.com/’ and similar to
 ‘/home/user/example/index.php’.
 
    The ‘:rewrites’ rules are searched as a last resort if and only if no
 existing file name is matched.
 
    Two functions can help you filling ‘org-protocol-project-alist’ with
 valid contents: ‘org-protocol-create’ and ‘org-protocol-create-for-org’.
 The latter is of use if you’re editing an Org file that is part of a
 publishing project.

 17.17 Org Crypt
 ===============
 
 Org Crypt encrypts the text of an entry, but not the headline, or
 properties.  Behind the scene, it uses the *note Emacs EasyPG Library:
 (epa)Top. to encrypt and decrypt files, and EasyPG needs a correct *note
 GnuPG: (gnupg)Top. setup.
 
    Any text below a headline that has a ‘crypt’ tag is automatically
 encrypted when the file is saved.  To use a different tag, customize the
 ‘org-crypt-tag-matcher’ setting.
 
    Here is a suggestion for Org Crypt settings in Emacs init file:
 
      (require 'org-crypt)
      (org-crypt-use-before-save-magic)
      (setq org-tags-exclude-from-inheritance '("crypt"))
 
      (setq org-crypt-key nil)
      ;; GPG key to use for encryption.
      ;; nil means  use symmetric encryption unconditionally.
      ;; "" means use symmetric encryption unless heading sets CRYPTKEY property.
 
      (setq auto-save-default nil)
      ;; Auto-saving does not cooperate with org-crypt.el: so you need to
      ;; turn it off if you plan to use org-crypt.el quite often.  Otherwise,
      ;; you'll get an (annoying) message each time you start Org.
 
      ;; To turn it off only locally, you can insert this:
      ;;
      ;; # -*- buffer-auto-save-file-name: nil; -*-
 
    It’s possible to use different keys for different headings by
 specifying the respective key as property ‘CRYPTKEY’, e.g.:
 
      * Totally secret :crypt:
        :PROPERTIES:
        :CRYPTKEY: 0x0123456789012345678901234567890123456789
        :END:
 
    Note that the ‘CRYPTKEY’ property is only effective when
 ‘org-crypt-key’ is non-‘nil’.  If ‘org-crypt-key’ is ‘nil’, Org uses
 symmetric encryption unconditionally.
 
    Excluding the ‘crypt’ tag from inheritance prevents already encrypted
 text from being encrypted again.

 17.18 Org Mobile
 ================
 
 Org Mobile is a protocol for synchronizing Org files between Emacs and
 other applications, e.g., on mobile devices.  It enables offline-views
 and capture support for an Org mode system that is rooted on a “real”
 computer.  The external application can also record changes to existing
 entries.
 
    This appendix describes Org’s support for agenda view formats
 compatible with Org Mobile.  It also describes synchronizing changes,
 such as to notes, between the mobile application and the computer.
 
    To change tags and TODO states in the mobile application, first
 customize the variables ‘org-todo-keywords’, ‘org-tag-alist’ and
 ‘org-tag-persistent-alist’.  These should cover all the important tags
 and TODO keywords, even if Org files use only some of them.  Though the
 mobile application is expected to support in-buffer settings, it is
 required to understand TODO states _sets_ (see *note Per-file
 keywords::) and _mutually exclusive_ tags (see *note Setting Tags::)
 only for those set in these variables.
 
 * Menu:
 
 * Setting up the staging area::  For the mobile device.
 * Pushing to the mobile application:: Uploading Org files and agendas.
 * Pulling from the mobile application:: Integrating captured and flagged items.
 
 
 File: org.info,  Node: Setting up the staging area,  Next: Pushing to the mobile application,  Up: Org Mobile
 
 17.18.1 Setting up the staging area
 -----------------------------------
 
 The mobile application needs access to a file directory on a server(1)
 to interact with Emacs.  Pass its location through the
 ‘org-mobile-directory’ variable.  If you can mount that directory
 locally just set the variable to point to that directory:
 
      (setq org-mobile-directory "~/orgmobile/")
 
    Alternatively, by using TRAMP (see *note TRAMP User Manual:
 (tramp)Top.), ‘org-mobile-directory’ may point to a remote directory
 accessible through, for example, SSH, SCP, or DAVS:
 
      (setq org-mobile-directory "/davs:user@remote.host:/org/webdav/")
 
    With a public server, consider encrypting the files.  Org also
 requires OpenSSL installed on the local computer.  To turn on
 encryption, set the same password in the mobile application and in
 Emacs.  Set the password in the variable ‘org-mobile-use-encryption’(2).
 Note that even after the mobile application encrypts the file contents,
 the file name remains visible on the file systems of the local computer,
 the server, and the mobile device.
 
    ---------- Footnotes ----------
 
    (1) For a server to host files, consider using a WebDAV server, such
 as Nextcloud (https://nextcloud.com).  Additional help is at this FAQ
 entry (https://orgmode.org/worg/org-faq.html#mobileorg_webdav).
 
    (2) If Emacs is configured for safe storing of passwords, then
 configure the variable ‘org-mobile-encryption-password’; please read the
 docstring of that variable.
 
 
 File: org.info,  Node: Pushing to the mobile application,  Next: Pulling from the mobile application,  Prev: Setting up the staging area,  Up: Org Mobile
 
 17.18.2 Pushing to the mobile application
 -----------------------------------------
 
 The command ‘org-mobile-push’ copies files listed in ‘org-mobile-files’
 into the staging area.  Files include agenda files (as listed in
 ‘org-agenda-files’).  Customize ‘org-mobile-files’ to add other files.
 File names are staged with paths relative to ‘org-directory’, so all
 files should be inside this directory(1).
 
    Push creates a special Org file ‘agendas.org’ with custom agenda
 views defined by the user(2).
 
    Finally, Org writes the file ‘index.org’, containing links to other
 files.  The mobile application reads this file first from the server to
 determine what other files to download for agendas.  For faster
 downloads, it is expected to only read files whose checksums(3) have
 changed.
 
    ---------- Footnotes ----------
 
    (1) Symbolic links in ‘org-directory’ need to have the same name as
 their targets.
 
    (2) While creating the agendas, Org mode forces ‘ID’ properties on
 all referenced entries, so that these entries can be uniquely identified
 if Org Mobile flags them for further action.  To avoid setting
 properties configure the variable ‘org-mobile-force-id-on-agenda-items’
 to ‘nil’.  Org mode then relies on outline paths, assuming they are
 unique.
 
    (3) Checksums are stored automatically in the file ‘checksums.dat’.
 
 
 File: org.info,  Node: Pulling from the mobile application,  Prev: Pushing to the mobile application,  Up: Org Mobile
 
 17.18.3 Pulling from the mobile application
 -------------------------------------------
 
 The command ‘org-mobile-pull’ synchronizes changes with the server.
 More specifically, it first pulls the Org files for viewing.  It then
 appends captured entries and pointers to flagged or changed entries to
 the file ‘mobileorg.org’ on the server.  Org ultimately integrates its
 data in an inbox file format, through the following steps:
 
   1. Org moves all entries found in ‘mobileorg.org’(1) and appends them
      to the file pointed to by the variable ‘org-mobile-inbox-for-pull’.
      It should reside neither in the staging area nor on the server.
      Each captured entry and each editing event is a top-level entry in
      the inbox file.
 
   2. After moving the entries, Org processes changes to the shared
      files.  Some of them are applied directly and without user
      interaction.  Examples include changes to tags, TODO state,
      headline and body text.  Entries requiring further action are
      tagged as ‘FLAGGED’.  Org marks entries with problems with an error
      message in the inbox.  They have to be resolved manually.
 
   3. Org generates an agenda view for flagged entries for user
      intervention to clean up.  For notes stored in flagged entries, Org
      displays them in the echo area when point is on the corresponding
      agenda item.
 
      ‘?’
           Pressing ‘?’ displays the entire flagged note in another
           window.  Org also pushes it to the kill ring.  To store
           flagged note as a normal note, use ‘? z C-y C-c C-c’.
           Pressing ‘?’ twice does these things: first it removes the
           ‘FLAGGED’ tag; second, it removes the flagged note from the
           property drawer; third, it signals that manual editing of the
           flagged entry is now finished.
 
    From the agenda dispatcher, ‘?’ returns to the view to finish
 processing flagged entries.  Note that these entries may not be the most
 recent since the mobile application searches files that were last
 pulled.  To get an updated agenda view with changes since the last pull,
 pull again.

 17.19 Drag and Drop & ‘yank-media’
 ==================================
 
 Org mode supports drag and drop (DnD) of files.  By default, Org asks
 the user what must be done with the dropped file: attach it, insert
 ‘file:’ link, or open the file.  Customize ‘org-yank-dnd-method’ to set
 the default DnD action.
 
    When DnD method is “attach”, Org mode first consults DnD metadata to
 decide the attach method.  For example, when file/files are dragged from
 a file manager, Org may attach by copying or by moving.
 
    If Org cannot figure out which attachment method to use from the
 metadata, it defaults to ‘org-yank-dnd-default-attach-method’ (1)
 
    Starting from Emacs 29, Org mode supports ‘yank-media’ command to
 yank images from the clipboard and files from a file manager.
 
    When yanking images from clipboard, Org saves the image on disk and
 inserts the image link to Org buffer.  Images are either saved as
 attachments to heading (default) or to a globally defined directory.
 The save location is controlled by ‘org-yank-image-save-method’.
 
    The yanked images are saved under automatically generated name.  You
 can customize ‘org-yank-image-file-name-function’ to make Org query the
 image names or change the naming scheme.
 
    When yanking files copied from a file manager, Org respects the value
 of ‘org-yank-dnd-method’.  Image files pasted this way also respect the
 value of ‘org-yank-image-save-method’ when the action to perform is
 ‘attach’.
 
    ---------- Footnotes ----------
 
    (1) By default, ‘org-yank-dnd-default-attach-method’ is set to nil –
 use the same value as ‘org-attach-method’ (‘cp’ by default).

 A.1 Hooks
 =========
 
 Org has a large number of hook variables for adding functionality.  A
 complete list of hooks with documentation is maintained by the Worg
 project at <https://orgmode.org/worg/doc.html#hooks>.
 
 
 File: org.info,  Node: Add-on Packages,  Next: Adding Hyperlink Types,  Prev: Hooks,  Up: Hacking
 
 A.2 Add-on Packages
 ===================
 
 Various authors wrote a large number of add-on packages for Org.  Some
 of these packages used to be part of the ‘org-mode’ repository but are
 now hosted in a separate ‘org-contrib’ repository here
 (https://git.sr.ht/~bzg/org-contrib).  A Worg page with more information
 is at: <https://orgmode.org/worg/org-contrib/>.
 
 
 File: org.info,  Node: Adding Hyperlink Types,  Next: Adding Export Backends,  Prev: Add-on Packages,  Up: Hacking
 
 A.3 Adding Hyperlink Types
 ==========================
 
 Org has many built-in hyperlink types (see *note Hyperlinks::), and an
 interface for adding new link types.  The following example shows the
 process of adding Org links to Unix man pages, which look like this
 
      [[man:printf][The printf manual]]
 
 The following ‘ol-man.el’ file implements it
 
      ;;; ol-man.el - Support for links to man pages in Org mode
      (require 'ol)
 
      (org-link-set-parameters "man"
                               :follow #'org-man-open
                               :export #'org-man-export
                               :store #'org-man-store-link)
 
      (defcustom org-man-command 'man
        "The Emacs command to be used to display a man page."
        :group 'org-link
        :type '(choice (const man) (const woman)))
 
      (defun org-man-open (path _)
        "Visit the manpage on PATH.
      PATH should be a topic that can be thrown at the man command."
        (funcall org-man-command path))
 
      (defun org-man-store-link (&optional _interactive?)
        "Store a link to a man page."
        (when (memq major-mode '(Man-mode woman-mode))
          ;; This is a man page, we do make this link.
          (let* ((page (org-man-get-page-name))
                 (link (concat "man:" page))
                 (description (format "Man page for %s" page)))
            (org-link-store-props
             :type "man"
             :link link
             :description description))))
 
      (defun org-man-get-page-name ()
        "Extract the page name from the buffer name."
        ;; This works for both `Man-mode' and `woman-mode'.
        (if (string-match " \\(\\S-+\\)\\*" (buffer-name))
            (match-string 1 (buffer-name))
          (error "Cannot create link to this man page")))
 
      (defun org-man-export (link description format _)
        "Export a man page link from Org files."
        (let ((path (format "http://man.he.net/?topic=%s&section=all" link))
              (desc (or description link)))
          (pcase format
            (`html (format "<a target=\"_blank\" href=\"%s\">%s</a>" path desc))
            (`latex (format "\\href{%s}{%s}" path desc))
            (`texinfo (format "@uref{%s,%s}" path desc))
            (`ascii (format "%s (%s)" desc path))
            (t path))))
 
      (provide ol-man)
      ;;; ol-man.el ends here
 
 To activate links to man pages in Org, enter this in the Emacs init
 file:
 
      (require 'ol-man)
 
 A review of ‘ol-man.el’:
 
   1. First, ‘(require 'ol)’ ensures that ‘ol.el’ is loaded.
 
   2. Then ‘org-link-set-parameters’ defines a new link type with ‘man’
      prefix and associates functions for following, exporting and
      storing such links.  See the variable ‘org-link-parameters’ for a
      complete list of possible associations.
 
   3. The rest of the file implements necessary variables and functions.
 
      For example, ‘org-man-store-link’ is responsible for storing a link
      when ‘org-store-link’ (see *note Handling Links::) is called from a
      buffer displaying a man page.  It is passed an argument
      ‘interactive?’ which this function does not use, but other store
      functions use to behave differently when a link is stored
      interactively by the user.  It first checks if the major mode is
      appropriate.  If check fails, the function returns ‘nil’, which
      means it isn’t responsible for creating a link to the current
      buffer.  Otherwise the function makes a link string by combining
      the ‘man:’ prefix with the man topic.  It also provides a default
      description.  The function ‘org-insert-link’ can insert it back
      into an Org buffer later on.

 A.4 Adding Export Backends
 ==========================
 
 Org’s export engine makes it easy for writing new backends.  The
 framework on which the engine was built makes it easy to derive new
 backends from existing ones.
 
    The two main entry points to the export engine are:
 ‘org-export-define-backend’ and ‘org-export-define-derived-backend’.  To
 grok these functions, see ‘ox-latex.el’ for an example of defining a new
 backend from scratch, and ‘ox-beamer.el’ for an example of deriving from
 an existing engine.
 
    For creating a new backend from scratch, first set its name as a
 symbol in an alist consisting of elements and export functions.  To make
 the backend visible to the export dispatcher, set ‘:menu-entry’ keyword.
 For export options specific to this backend, set the ‘:options-alist’.
 
    For creating a new backend from an existing one, set
 ‘:translate-alist’ to an alist of export functions.  This alist replaces
 the parent backend functions.
 
    For complete documentation, see the Org Export Reference on Worg
 (https://orgmode.org/worg/dev/org-export-reference.html).

 A.5 Tables in Arbitrary Syntax
 ==============================
 
 Due to Org’s success in handling tables with Orgtbl, a frequently
 requested feature is the use of Org’s table functions in other modes,
 e.g., LaTeX.  This would be hard to do in a general way without
 complicated customization nightmares.  Moreover, that would take Org
 away from its simplicity roots that Orgtbl has proven.  There is,
 however, an alternate approach to accomplishing the same.
 
    This approach involves implementing a custom _translate_ function
 that operates on a native Org _source table_ to produce a table in
 another format.  This strategy would keep the excellently working Orgtbl
 simple and isolate complications, if any, confined to the translate
 function.  To add more alien table formats, we just add more translate
 functions.  Also the burden of developing custom translate functions for
 new table formats is in the hands of those who know those formats best.

 File: org.info,  Node: Radio tables,  Next: A LaTeX example,  Up: Tables in Arbitrary Syntax
 
 A.5.1 Radio tables
 ------------------
 
 Radio tables are target locations for translated tables that are not
 near their source.  Org finds the target location and inserts the
 translated table.
 
    The key to finding the target location is the magic words ‘BEGIN/END
 RECEIVE ORGTBL’.  They have to appear as comments in the current mode.
 If the mode is C, then:
 
      /* BEGIN RECEIVE ORGTBL table_name */
      /* END RECEIVE ORGTBL table_name */
 
    At the location of source, Org needs a special line to direct Orgtbl
 to translate and to find the target for inserting the translated table.
 For example:
 
      #+ORGTBL: SEND table_name translation_function arguments ...
 
 ‘table_name’ is the table’s reference name, which is also used in the
 receiver lines, and the ‘translation_function’ is the Lisp function that
 translates.  This line, in addition, may also contain alternating key
 and value arguments at the end.  The translation function gets these
 values as a property list.  A few standard parameters are already
 recognized and acted upon before the translation function is called:
 
 ‘:skip N’
      Skip the first N lines of the table.  Hlines do count; include them
      if they are to be skipped.
 
 ‘:skipcols (n1 n2 ...)’
      List of columns to be skipped.  First Org automatically discards
      columns with calculation marks and then sends the table to the
      translator function, which then skips columns as specified in
      ‘skipcols’.
 
    To keep the source table intact in the buffer without being disturbed
 when the source file is compiled or otherwise being worked on, use one
 of these strategies:
 
    • Place the table in a block comment.  For example, in C mode you
      could wrap the table between ‘/*’ and ‘*/’ lines.
 
    • Put the table after an “end” statement.  For example ‘\bye’ in TeX
      and ‘\end{document}’ in LaTeX.
 
    • Comment and un-comment each line of the table during edits.  The
      ‘M-x orgtbl-toggle-comment’ command makes toggling easy.
 
 
 File: org.info,  Node: A LaTeX example,  Next: Translator functions,  Prev: Radio tables,  Up: Tables in Arbitrary Syntax
 
 A.5.2 A LaTeX example of radio tables
 -------------------------------------
 
 To wrap a source table in LaTeX, use the ‘comment’ environment provided
 by ‘comment.sty’(1).  To activate it, put ‘\usepackage{comment}’ in the
 document header.  Orgtbl mode inserts a radio table skeleton(2) with the
 command ‘M-x orgtbl-insert-radio-table’, which prompts for a table name.
 For example, if ‘salesfigures’ is the name, the template inserts:
 
      % BEGIN RECEIVE ORGTBL salesfigures
      % END RECEIVE ORGTBL salesfigures
      \begin{comment}
      #+ORGTBL: SEND salesfigures orgtbl-to-latex
      | | |
      \end{comment}
 
 The line ‘#+ORGTBL: SEND’ tells Orgtbl mode to use the function
 ‘orgtbl-to-latex’ to convert the table to LaTeX format, then insert the
 table at the target (receive) location named ‘salesfigures’.  Now the
 table is ready for data entry.  It can even use spreadsheet features(3):
 
      % BEGIN RECEIVE ORGTBL salesfigures
      % END RECEIVE ORGTBL salesfigures
      \begin{comment}
      #+ORGTBL: SEND salesfigures orgtbl-to-latex
      | Month | Days | Nr sold | per day |
      |-------+------+---------+---------|
      | Jan   |   23 |      55 |     2.4 |
      | Feb   |   21 |      16 |     0.8 |
      | March |   22 |     278 |    12.6 |
      #+TBLFM: $4=$3/$2;%.1f
      % $ (optional extra dollar to keep Font Lock happy, see footnote)
      \end{comment}
 
    After editing, ‘C-c C-c’ inserts the translated table at the target
 location, between the two marker lines.
 
    For hand-made custom tables, note that the translator needs to skip
 the first two lines of the source table.  Also the command has to
 _splice_ out the target table without the header and footer.
 
      \begin{tabular}{lrrr}
      Month & \multicolumn{1}{c}{Days} & Nr.\ sold & per day\\
      % BEGIN RECEIVE ORGTBL salesfigures
      % END RECEIVE ORGTBL salesfigures
      \end{tabular}
      %
      \begin{comment}
      #+ORGTBL: SEND salesfigures orgtbl-to-latex :splice t :skip 2
      | Month | Days | Nr sold | per day |
      |-------+------+---------+---------|
      | Jan   |   23 |      55 |     2.4 |
      | Feb   |   21 |      16 |     0.8 |
      | March |   22 |     278 |    12.6 |
      #+TBLFM: $4=$3/$2;%.1f
      \end{comment}
 
    The LaTeX translator function ‘orgtbl-to-latex’ is already part of
 Orgtbl mode and uses a ‘tabular’ environment to typeset the table and
 marks horizontal lines with ‘\hline’.  For additional parameters to
 control output, see *note Translator functions:::
 
 ‘:splice BOOLEAN’
      When {{{var(BOOLEAN}}} is non-‘nil’, return only table body lines;
      i.e., not wrapped in ‘tabular’ environment.  Default is ‘nil’.
 
 ‘:fmt FMT’
      Format string to warp each field.  It should contain ‘%s’ for the
      original field value.  For example, to wrap each field value in
      dollar symbol, you could use ‘:fmt "$%s$"’.  Format can also wrap a
      property list with column numbers and formats, for example ‘:fmt (2
      "$%s$" 4 "%s\\%%")’.  In place of a string, a function of one
      argument can be used; the function must return a formatted string.
 
 ‘:efmt EFMT’
      Format numbers as exponentials.  The spec should have ‘%s’ twice
      for inserting mantissa and exponent, for example
      ‘"%s\\times10^{%s}"’.  This may also be a property list with column
      numbers and formats, for example ‘:efmt (2 "$%s\\times10^{%s}$" 4
      "$%s\\cdot10^{%s}$")’.  After EFMT has been applied to a value,
      FMT—see above—is also applied.  Functions with two arguments can be
      supplied instead of strings.  By default, no special formatting is
      applied.
 
    ---------- Footnotes ----------
 
    (1) <https://www.ctan.org/pkg/comment>
 
    (2) By default this works only for LaTeX, HTML, and Texinfo.
 Configure the variable ‘orgtbl-radio-table-templates’ to install
 templates for other modes.
 
    (3) If the ‘TBLFM’ keyword contains an odd number of dollar
 characters, this may cause problems with Font Lock in LaTeX mode.  As
 shown in the example you can fix this by adding an extra line inside the
 ‘comment’ environment that is used to balance the dollar expressions.
 If you are using AUCTeX with the font-latex library, a much better
 solution is to add the ‘comment’ environment to the variable
 ‘LaTeX-verbatim-environments’.

 A.5.3 Translator functions
 --------------------------
 
 Orgtbl mode has built-in translator functions: ‘orgtbl-to-csv’
 (comma-separated values), ‘orgtbl-to-tsv’ (TAB-separated values),
 ‘orgtbl-to-latex’, ‘orgtbl-to-html’, ‘orgtbl-to-texinfo’,
 ‘orgtbl-to-unicode’ and ‘orgtbl-to-orgtbl’.  They use the generic
 translator, ‘orgtbl-to-generic’, which delegates translations to various
 export backends.
 
    Properties passed to the function through the ‘ORGTBL SEND’ line take
 precedence over properties defined inside the function.  For example,
 this overrides the default LaTeX line endings, ‘\\’, with ‘\\[2mm]’:
 
      #+ORGTBL: SEND test orgtbl-to-latex :lend " \\\\[2mm]"
 
    For a new language translator, define a converter function.  It can
 be a generic function, such as shown in this example.  It marks a
 beginning and ending of a table with ‘!BTBL!’ and ‘!ETBL!’; a beginning
 and ending of lines with ‘!BL!’ and ‘!EL!’; and uses a TAB for a field
 separator:
 
      (defun orgtbl-to-language (table params)
        "Convert the orgtbl-mode TABLE to language."
        (orgtbl-to-generic
         table
         (org-combine-plists
          '(:tstart "!BTBL!" :tend "!ETBL!" :lstart "!BL!" :lend "!EL!" :sep "\t")
          params)))
 
 The documentation for the ‘orgtbl-to-generic’ function shows a complete
 list of parameters, each of which can be passed through to
 ‘orgtbl-to-latex’, ‘orgtbl-to-texinfo’, and any other function using
 that generic function.
 
    For complicated translations the generic translator function could be
 replaced by a custom translator function.  Such a custom function must
 take two arguments and return a single string containing the formatted
 table.  The first argument is the table whose lines are a list of fields
 or the symbol ‘hline’.  The second argument is the property list
 consisting of parameters specified in the ‘#+ORGTBL: SEND’ line.  Please
 share your translator functions by posting them to the Org users mailing
 list, at <mailto:emacs-orgmode@gnu.org>.
 
 
 File: org.info,  Node: Dynamic Blocks,  Next: Special Agenda Views,  Prev: Tables in Arbitrary Syntax,  Up: Hacking
 
 A.6 Dynamic Blocks
 ==================
 
 Org supports _dynamic blocks_ in Org documents.  They are inserted with
 begin and end markers like any other code block, but the contents are
 updated automatically by a user function.
 
    You can insert a dynamic block with
 ‘org-dynamic-block-insert-dblock’, which is bound to ‘C-c C-x x’ by
 default.  For example, ‘C-c C-x x c l o c k t a b l e <RET>’ inserts a
 table that updates the work time (see *note Clocking Work Time::).
 
    Dynamic blocks can have names and function parameters.  The syntax is
 similar to source code block specifications:
 
      #+BEGIN: myblock :parameter1 value1 :parameter2 value2 ...
        ...
      #+END:
 
    These commands update dynamic blocks:
 
 ‘C-c C-x C-u’ (‘org-dblock-update’)
      Update dynamic block at point.
 
 ‘C-u C-c C-x C-u’
      Update all dynamic blocks in the current file.
 
    Before updating a dynamic block, Org removes content between the
 ‘BEGIN’ and ‘END’ markers.  Org then reads the parameters on the ‘BEGIN’
 line for passing to the writer function as a plist.  The previous
 content of the dynamic block becomes erased from the buffer and appended
 to the plist under ‘:content’.
 
    The syntax for naming a writer function with a dynamic block labeled
 ‘myblock’ is: ‘org-dblock-write:myblock’.
 
    The following is an example of a dynamic block and a block writer
 function that updates the time when the function was last run:
 
      #+BEGIN: block-update-time :format "on %m/%d/%Y at %H:%M"
        ...
      #+END:
 
 The dynamic block’s writer function:
 
      (defun org-dblock-write:block-update-time (params)
        (let ((fmt (or (plist-get params :format) "%d. %m. %Y")))
          (insert "Last block update at: "
                  (format-time-string fmt))))
 
    To keep dynamic blocks up-to-date in an Org file, use the function,
 ‘org-update-all-dblocks’ in hook, such as ‘before-save-hook’.  The
 ‘org-update-all-dblocks’ function does not run if the file is not in Org
 mode.
 
    Dynamic blocks, like any other block, can be narrowed with
 ‘org-narrow-to-block’.
 
 
 File: org.info,  Node: Special Agenda Views,  Next: Speeding Up Your Agendas,  Prev: Dynamic Blocks,  Up: Hacking
 
 A.7 Special Agenda Views
 ========================
 
 Org provides a special hook to further limit items in agenda views:
 ‘agenda’, ‘agenda*’(1), ‘todo’, ‘alltodo’, ‘tags’, ‘tags-todo’,
 ‘tags-tree’.  Specify a custom function that tests inclusion of every
 matched item in the view.  This function can also skip as much as is
 needed.
 
    For a global condition applicable to agenda views, use the
 ‘org-agenda-skip-function-global’ variable.  Org uses a global condition
 with ‘org-agenda-skip-function’ for custom searching.
 
    This example defines a function for a custom view showing TODO items
 with ‘waiting’ status.  Manually this is a multi-step search process,
 but with a custom view, this can be automated as follows:
 
    The custom function searches the subtree for the ‘waiting’ tag and
 returns ‘nil’ on match.  Otherwise it gives the location from where the
 search continues.
 
      (defun my-skip-unless-waiting ()
        "Skip trees that are not waiting"
        (let ((subtree-end (save-excursion (org-end-of-subtree t))))
          (if (re-search-forward ":waiting:" subtree-end t)
              nil          ; tag found, do not skip
            subtree-end))) ; tag not found, continue after end of subtree
 
    To use this custom function in a custom agenda command:
 
      (org-add-agenda-custom-command
       '("b" todo "PROJECT"
         ((org-agenda-skip-function 'my-skip-unless-waiting)
          (org-agenda-overriding-header "Projects waiting for something: "))))
 
    Note that this also binds ‘org-agenda-overriding-header’ to a more
 meaningful string suitable for the agenda view.
 
    Search for entries with a limit set on levels for the custom search.
 This is a general approach to creating custom searches in Org.  To
 include all levels, use ‘LEVEL>0’(2).  Then to selectively pick the
 matched entries, use ‘org-agenda-skip-function’, which also accepts Lisp
 forms, such as ‘org-agenda-skip-entry-if’ and
 ‘org-agenda-skip-subtree-if’.  For example:
 
 ‘(org-agenda-skip-entry-if 'scheduled)’
      Skip current entry if it has been scheduled.
 
 ‘(org-agenda-skip-entry-if 'notscheduled)’
      Skip current entry if it has not been scheduled.
 
 ‘(org-agenda-skip-entry-if 'deadline)’
      Skip current entry if it has a deadline.
 
 ‘(org-agenda-skip-entry-if 'scheduled 'deadline)’
      Skip current entry if it has a deadline, or if it is scheduled.
 
 ‘(org-agenda-skip-entry-if 'todo '("TODO" "WAITING"))’
      Skip current entry if the TODO keyword is TODO or WAITING.
 
 ‘(org-agenda-skip-entry-if 'todo 'done)’
      Skip current entry if the TODO keyword marks a DONE state.
 
 ‘(org-agenda-skip-entry-if 'timestamp)’
      Skip current entry if it has any timestamp, may also be deadline or
      scheduled.
 
 ‘(org-agenda-skip-entry-if 'regexp "regular expression")’
      Skip current entry if the regular expression matches in the entry.
 
 ‘(org-agenda-skip-entry-if 'notregexp "regular expression")’
      Skip current entry unless the regular expression matches.
 
 ‘(org-agenda-skip-subtree-if 'regexp "regular expression")’
      Same as above, but check and skip the entire subtree.
 
    The following is an example of a search for ‘waiting’ without the
 special function:
 
      (org-add-agenda-custom-command
       '("b" todo "PROJECT"
         ((org-agenda-skip-function '(org-agenda-skip-subtree-if
                                      'regexp ":waiting:"))
          (org-agenda-overriding-header "Projects waiting for something: "))))
 
    ---------- Footnotes ----------
 
    (1) The ‘agenda*’ view is the same as ‘agenda’ except that it only
 considers _appointments_, i.e., scheduled and deadline items that have a
 time specification ‘[h]h:mm’ in their timestamps.
 
    (2) Note that, for ‘org-odd-levels-only’, a level number corresponds
 to order in the hierarchy, not to the number of stars.

 A.8 Speeding Up Your Agendas
 ============================
 
 Some agenda commands slow down when the Org files grow in size or
 number.  Here are tips to speed up:
 
    • Reduce the number of Org agenda files to avoid slowdowns due to
      hard drive accesses.
 
    • Reduce the number of DONE and archived headlines so agenda
      operations that skip over these can finish faster.
 
    • Do not dim blocked tasks:
 
           (setq org-agenda-dim-blocked-tasks nil)
 
    • Stop preparing agenda buffers on startup:
 
           (setq org-agenda-inhibit-startup t)
 
    • Disable tag inheritance for agendas:
 
           (setq org-agenda-use-tag-inheritance nil)
 
    • Disable parsing of some properties:
 
           (setq org-agenda-ignore-properties '(stats))
 
      This will disable parsing and updating statistic cookies.
 
    These options can be applied to selected agenda views.  For more
 details about generation of agenda views, see the docstrings for the
 relevant variables, and this dedicated Worg page
 (https://orgmode.org/worg/agenda-optimization.html) for agenda
 optimization.

 A.9 Extracting Agenda Information
 =================================
 
 Org provides commands to access agendas through Emacs batch mode.
 Through this command-line interface, agendas are automated for further
 processing or printing.
 
    ‘org-batch-agenda’ creates an agenda view in ASCII and outputs to
 standard output.  This command takes one string parameter.  When string
 consists of a single character, Org uses it as a key to
 ‘org-agenda-custom-commands’.  These are the same ones available through
 the agenda dispatcher (see *note Agenda Dispatcher::).
 
    This example command line directly prints the TODO list to the
 printer:
 
      emacs -batch -l ~/.emacs -eval '(org-batch-agenda "t")' | lpr
 
    When the string parameter length is two or more characters, Org
 matches it with tags/TODO strings.  For example, this example command
 line prints items tagged with ‘shop’, but excludes items tagged with
 ‘NewYork’:
 
      emacs -batch -l ~/.emacs                                      \
            -eval '(org-batch-agenda "+shop-NewYork")' | lpr
 
 An example showing on-the-fly parameter modifications:
 
      emacs -batch -l ~/.emacs                                      \
         -eval '(org-batch-agenda "a"                               \
                 org-agenda-span (quote month)                      \
                 org-agenda-include-diary nil                       \
                 org-agenda-files (quote ("~/org/project.org")))'   \
         | lpr
 
 which produces an agenda for the next 30 days from just the
 ‘~/org/projects.org’ file.
 
    For structured processing of agenda output, use
 ‘org-batch-agenda-csv’ with the following fields:
 
 category
      The category of the item
 head
      The headline, without TODO keyword, TAGS and PRIORITY
 type
      The type of the agenda entry, can be
 
      ‘todo’                selected in TODO match
      ‘tagsmatch’           selected in tags match
      ‘diary’               imported from diary
      ‘deadline’            a deadline
      ‘scheduled’           scheduled
      ‘timestamp’           appointment, selected by timestamp
      ‘closed’              entry was closed on date
      ‘upcoming-deadline’   warning about nearing deadline
      ‘past-scheduled’      forwarded scheduled item
      ‘block’               entry has date block including date
 
 todo
      The TODO keyword, if any
 tags
      All tags including inherited ones, separated by colons
 date
      The relevant date, like ‘2007-2-14’
 time
      The time, like ‘15:00-16:50’
 extra
      String with extra planning info
 priority-l
      The priority letter if any was given
 priority-n
      The computed numerical priority
 
    If the selection of the agenda item was based on a timestamp,
 including those items with ‘DEADLINE’ and ‘SCHEDULED’ keywords, then Org
 includes date and time in the output.
 
    If the selection of the agenda item was based on a timestamp (or
 deadline/scheduled), then Org includes date and time in the output.
 
    Here is an example of a post-processing script in Perl.  It takes the
 CSV output from Emacs and prints with a checkbox:
 
      #!/usr/bin/perl
 
      # define the Emacs command to run
      $cmd = "emacs -batch -l ~/.emacs -eval '(org-batch-agenda-csv \"t\")'";
 
      # run it and capture the output
      $agenda = qx{$cmd 2>/dev/null};
 
      # loop over all lines
      foreach $line (split(/\n/,$agenda)) {
          # get the individual values
          ($category,$head,$type,$todo,$tags,$date,$time,$extra,
           $priority_l,$priority_n) = split(/,/,$line);
          # process and print
          print "[ ] $head\n";
      }

 A.10 Using the Property API
 ===========================
 
 Here is a description of the functions that can be used to work with
 properties.
 
  -- Function: org-entry-properties &optional pom which
      Get all properties of the entry at point-or-marker POM.  This
      includes the TODO keyword, the tags, time strings for deadline,
      scheduled, and clocking, and any additional properties defined in
      the entry.  The return value is an alist.  Keys may occur multiple
      times if the property key was used several times.  POM may also be
      ‘nil’, in which case the current entry is used.  If WHICH is ‘nil’
      or ‘all’, get all properties.  If WHICH is ‘special’ or ‘standard’,
      only get that subclass.
 
  -- Function: org-entry-get pom property &optional inherit
      Get value of PROPERTY for entry at point-or-marker POM.  By
      default, this only looks at properties defined locally in the
      entry.  If INHERIT is non-‘nil’ and the entry does not have the
      property, then also check higher levels of the hierarchy.  If
      INHERIT is the symbol ‘selective’, use inheritance if and only if
      the setting of ‘org-use-property-inheritance’ selects PROPERTY for
      inheritance.
 
  -- Function: org-entry-delete pom property
      Delete the property PROPERTY from entry at point-or-marker POM.
 
  -- Function: org-entry-put pom property value
      Set PROPERTY to VALUES for entry at point-or-marker POM.
 
  -- Function: org-buffer-property-keys &optional include-specials
      Get all property keys in the current buffer.
 
  -- Function: org-insert-property-drawer
      Insert a property drawer for the current entry.
 
  -- Function: org-entry-put-multivalued-property pom property &rest
           values
      Set PROPERTY at point-or-marker POM to VALUES.  VALUES should be a
      list of strings.  They are concatenated, with spaces as separators.
 
  -- Function: org-entry-get-multivalued-property pom property
      Treat the value of the property PROPERTY as a whitespace-separated
      list of values and return the values as a list of strings.
 
  -- Function: org-entry-add-to-multivalued-property pom property value
      Treat the value of the property PROPERTY as a whitespace-separated
      list of values and make sure that VALUE is in this list.
 
  -- Function: org-entry-remove-from-multivalued-property pom property
           value
      Treat the value of the property PROPERTY as a whitespace-separated
      list of values and make sure that VALUE is _not_ in this list.
 
  -- Function: org-entry-member-in-multivalued-property pom property
           value
      Treat the value of the property PROPERTY as a whitespace-separated
      list of values and check if VALUE is in this list.
 
  -- User Option: org-property-allowed-value-functions
      Hook for functions supplying allowed values for a specific
      property.  The functions must take a single argument, the name of
      the property, and return a flat list of allowed values.  If ‘:ETC’
      is one of the values, use the values as completion help, but allow
      also other values to be entered.  The functions must return ‘nil’
      if they are not responsible for this property.
 
 
 File: org.info,  Node: Using the Mapping API,  Prev: Using the Property API,  Up: Hacking
 
 A.11 Using the Mapping API
 ==========================
 
 Org has sophisticated mapping capabilities to find all entries
 satisfying certain criteria.  Internally, this functionality is used to
 produce agenda views, but there is also an API that can be used to
 execute arbitrary functions for each or selected entries.  The main
 entry point for this API is:
 
  -- Function: org-map-entries func &optional match scope &rest skip
      Call FUNC at each headline selected by MATCH in SCOPE.
 
      FUNC is a function or a Lisp form.  With point positioned at the
      beginning of the headline, call the function without arguments.
      Org returns a list of return values of calls to the function.
 
      To avoid preserving point, Org wraps the call to FUNC in
      ‘save-excursion’ form.  After evaluation, Org moves point to the
      end of the line that was just processed.  Search continues from
      that point forward.  This may not always work as expected under
      some conditions, such as if the current subtree was removed by a
      previous archiving operation.  In such rare circumstances, Org
      skips the next entry entirely when it should not.  To stop Org from
      such skips, make FUNC set the variable ‘org-map-continue-from’ to a
      specific buffer position.
 
      MATCH is a tags/property/TODO match.  Org iterates only matched
      headlines.  Org iterates over all headlines when MATCH is ‘nil’ or
      ‘t’.
 
      SCOPE determines the scope of this command.  It can be any of:
 
      ‘nil’
           The current buffer, respecting the restriction, if any.
 
      ‘tree’
           The subtree started with the entry at point.
 
      ‘region’
           The entries within the active region, if any.
 
      ‘file’
           The current buffer, without restriction.
 
      ‘file-with-archives’
           The current buffer, and any archives associated with it.
 
      ‘agenda’
           All agenda files.
 
      ‘agenda-with-archives’
           All agenda files with any archive files associated with them.
 
      list of filenames
           If this is a list, all files in the list are scanned.
 
      The remaining arguments are treated as settings for the scanner’s
      skipping facilities.  Valid arguments are:
 
      ‘archive’
           Skip trees with the ‘ARCHIVE’ tag.
 
      ‘comment’
           Skip trees with the COMMENT keyword.
 
      function or Lisp form
           Used as value for ‘org-agenda-skip-function’, so whenever the
           function returns ‘t’, FUNC is called for that entry and search
           continues from the point where the function leaves it.
 
    The mapping routine can call any arbitrary function, even functions
 that change meta data or query the property API (see *note Using the
 Property API::).  Here are some handy functions:
 
  -- Function: org-todo &optional arg
      Change the TODO state of the entry.  See the docstring of the
      functions for the many possible values for the argument ARG.
 
  -- Function: org-priority &optional action
      Change the priority of the entry.  See the docstring of this
      function for the possible values for ACTION.
 
  -- Function: org-toggle-tag tag &optional onoff
      Toggle the tag TAG in the current entry.  Setting ONOFF to either
      ‘on’ or ‘off’ does not toggle tag, but ensure that it is either on
      or off.
 
  -- Function: org-promote
      Promote the current entry.
 
  -- Function: org-demote
      Demote the current entry.
 
    This example turns all entries tagged with ‘TOMORROW’ into TODO
 entries with keyword ‘UPCOMING’.  Org ignores entries in comment trees
 and archive trees.
 
      (org-map-entries '(org-todo "UPCOMING")
                       "+TOMORROW" 'file 'archive 'comment)
 
    The following example counts the number of entries with TODO keyword
 ‘WAITING’, in all agenda files.
 
      (length (org-map-entries t "/+WAITING" 'agenda))

 Appendix B History and Acknowledgments
 **************************************
 
 B.1 From Carsten
 ================
 
 Org was born in 2003, out of frustration over the user interface of the
 Emacs Outline mode.  I was trying to organize my notes and projects, and
 using Emacs seemed to be the natural way to go.  However, having to
 remember eleven different commands with two or three keys per command,
 only to hide and show parts of the outline tree, that seemed entirely
 unacceptable to me.  Also, when using outlines to take notes, I
 constantly wanted to restructure the tree, organizing it parallel to my
 thoughts and plans.  _Visibility cycling_ and _structure editing_ were
 originally implemented in the package ‘outline-magic.el’, but quickly
 moved to the more general ‘org.el’.  As this environment became
 comfortable for project planning, the next step was adding _TODO
 entries_, basic _timestamps_, and _table support_.  These areas
 highlighted the two main goals that Org still has today: to be a new,
 outline-based, plain text mode with innovative and intuitive editing
 features, and to incorporate project planning functionality directly
 into a notes file.
 
    Since the first release, literally thousands of emails to me or to
 the mailing list <mailto:emacs-orgmode@gnu.org> have provided a constant
 stream of bug reports, feedback, new ideas, and sometimes patches and
 add-on code.  Many thanks to everyone who has helped to improve this
 package.  I am trying to keep here a list of the people who had
 significant influence in shaping one or more aspects of Org.  The list
 may not be complete, if I have forgotten someone, please accept my
 apologies and let me know.
 
    Before I get to this list, a few special mentions are in order:
 
 Bastien Guerry
      Bastien has written a large number of extensions to Org (most of
      them integrated into the core by now), including the LaTeX exporter
      and the plain list parser.  His support during the early days was
      central to the success of this project.  Bastien also invented
      Worg, helped establishing the Web presence of Org, and sponsored
      hosting costs for the orgmode.org website.  Bastien stepped in as
      maintainer of Org between 2011 and 2013, at a time when I
      desperately needed a break.
 
 Eric Schulte and Dan Davison
      Eric and Dan are jointly responsible for the Org Babel system,
      which turns Org into a multi-language environment for evaluating
      code and doing literate programming and reproducible research.
      This has become one of Org’s killer features that define what Org
      is today.
 
 John Wiegley
      John has contributed a number of great ideas and patches directly
      to Org, including the attachment system (‘org-attach.el’),
      integration with Apple Mail (‘org-mac-message.el’), hierarchical
      dependencies of TODO items, habit tracking (‘org-habits.el’), and
      encryption (‘org-crypt.el’).  Also, the capture system is really an
      extended copy of his great ‘remember.el’.
 
 Sebastian Rose
      Without Sebastian, the HTML/XHTML publishing of Org would be the
      pitiful work of an ignorant amateur.  Sebastian has pushed this
      part of Org onto a much higher level.  He also wrote ‘org-info.js’,
      a JavaScript program for displaying webpages derived from Org using
      an Info-like or a folding interface with single-key navigation.
 
    See below for the full list of contributions!  Again, please let me
 know what I am missing here!
 
 B.2 From Bastien
 ================
 
 I (Bastien) have been maintaining Org between 2011 and 2013.  This
 appendix would not be complete without adding a few more acknowledgments
 and thanks.
 
    I am first grateful to Carsten for his trust while handing me over
 the maintainership of Org.  His unremitting support is what really
 helped me getting more confident over time, with both the community and
 the code.
 
    When I took over maintainership, I knew I would have to make Org more
 collaborative than ever, as I would have to rely on people that are more
 knowledgeable than I am on many parts of the code.  Here is a list of
 the persons I could rely on, they should really be considered
 co-maintainers, either of the code or the community:
 
 Eric Schulte
      Eric is maintaining the Babel parts of Org.  His reactivity here
      kept me away from worrying about possible bugs here and let me
      focus on other parts.
 
 Nicolas Goaziou
      Nicolas is maintaining the consistency of the deepest parts of Org.
      His work on ‘org-element.el’ and ‘ox.el’ has been outstanding, and
      it opened the doors for many new ideas and features.  He rewrote
      many of the old exporters to use the new export engine, and helped
      with documenting this major change.  More importantly (if that’s
      possible), he has been more than reliable during all the work done
      for Org 8.0, and always very reactive on the mailing list.
 
 Achim Gratz
      Achim rewrote the building process of Org, turning some _ad hoc_
      tools into a flexible and conceptually clean process.  He patiently
      coped with the many hiccups that such a change can create for
      users.
 
 Nick Dokos
      The Org mode mailing list would not be such a nice place without
      Nick, who patiently helped users so many times.  It is impossible
      to overestimate such a great help, and the list would not be so
      active without him.
 
    I received support from so many users that it is clearly impossible
 to be fair when shortlisting a few of them, but Org’s history would not
 be complete if the ones above were not mentioned in this manual.

 *****************************************
 
                      Version 1.3, 3 November 2008
 
      Copyright © 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
      <https://fsf.org/>
 
      Everyone is permitted to copy and distribute verbatim copies
      of this license document, but changing it is not allowed.
 
   0. PREAMBLE
 
      The purpose of this License is to make a manual, textbook, or other
      functional and useful document “free” in the sense of freedom: to
      assure everyone the effective freedom to copy and redistribute it,
      with or without modifying it, either commercially or
      noncommercially.  Secondarily, this License preserves for the
      author and publisher a way to get credit for their work, while not
      being considered responsible for modifications made by others.
 
      This License is a kind of “copyleft”, which means that derivative
      works of the document must themselves be free in the same sense.
      It complements the GNU General Public License, which is a copyleft
      license designed for free software.
 
      We have designed this License in order to use it for manuals for
      free software, because free software needs free documentation: a
      free program should come with manuals providing the same freedoms
      that the software does.  But this License is not limited to
      software manuals; it can be used for any textual work, regardless
      of subject matter or whether it is published as a printed book.  We
      recommend this License principally for works whose purpose is
      instruction or reference.
 
   1. APPLICABILITY AND DEFINITIONS
 
      This License applies to any manual or other work, in any medium,
      that contains a notice placed by the copyright holder saying it can
      be distributed under the terms of this License.  Such a notice
      grants a world-wide, royalty-free license, unlimited in duration,
      to use that work under the conditions stated herein.  The
      “Document”, below, refers to any such manual or work.  Any member
      of the public is a licensee, and is addressed as “you”.  You accept
      the license if you copy, modify or distribute the work in a way
      requiring permission under copyright law.
 
      A “Modified Version” of the Document means any work containing the
      Document or a portion of it, either copied verbatim, or with
      modifications and/or translated into another language.
 
      A “Secondary Section” is a named appendix or a front-matter section
      of the Document that deals exclusively with the relationship of the
      publishers or authors of the Document to the Document’s overall
      subject (or to related matters) and contains nothing that could
      fall directly within that overall subject.  (Thus, if the Document
      is in part a textbook of mathematics, a Secondary Section may not
      explain any mathematics.)  The relationship could be a matter of
      historical connection with the subject or with related matters, or
      of legal, commercial, philosophical, ethical or political position
      regarding them.
 
      The “Invariant Sections” are certain Secondary Sections whose
      titles are designated, as being those of Invariant Sections, in the
      notice that says that the Document is released under this License.
      If a section does not fit the above definition of Secondary then it
      is not allowed to be designated as Invariant.  The Document may
      contain zero Invariant Sections.  If the Document does not identify
      any Invariant Sections then there are none.
 
      The “Cover Texts” are certain short passages of text that are
      listed, as Front-Cover Texts or Back-Cover Texts, in the notice
      that says that the Document is released under this License.  A
      Front-Cover Text may be at most 5 words, and a Back-Cover Text may
      be at most 25 words.
 
      A “Transparent” copy of the Document means a machine-readable copy,
      represented in a format whose specification is available to the
      general public, that is suitable for revising the document
      straightforwardly with generic text editors or (for images composed
      of pixels) generic paint programs or (for drawings) some widely
      available drawing editor, and that is suitable for input to text
      formatters or for automatic translation to a variety of formats
      suitable for input to text formatters.  A copy made in an otherwise
      Transparent file format whose markup, or absence of markup, has
      been arranged to thwart or discourage subsequent modification by
      readers is not Transparent.  An image format is not Transparent if
      used for any substantial amount of text.  A copy that is not
      “Transparent” is called “Opaque”.
 
      Examples of suitable formats for Transparent copies include plain
      ASCII without markup, Texinfo input format, LaTeX input format,
      SGML or XML using a publicly available DTD, and standard-conforming
      simple HTML, PostScript or PDF designed for human modification.
      Examples of transparent image formats include PNG, XCF and JPG.
      Opaque formats include proprietary formats that can be read and
      edited only by proprietary word processors, SGML or XML for which
      the DTD and/or processing tools are not generally available, and
      the machine-generated HTML, PostScript or PDF produced by some word
      processors for output purposes only.
 
      The “Title Page” means, for a printed book, the title page itself,
      plus such following pages as are needed to hold, legibly, the
      material this License requires to appear in the title page.  For
      works in formats which do not have any title page as such, “Title
      Page” means the text near the most prominent appearance of the
      work’s title, preceding the beginning of the body of the text.
 
      The “publisher” means any person or entity that distributes copies
      of the Document to the public.
 
      A section “Entitled XYZ” means a named subunit of the Document
      whose title either is precisely XYZ or contains XYZ in parentheses
      following text that translates XYZ in another language.  (Here XYZ
      stands for a specific section name mentioned below, such as
      “Acknowledgements”, “Dedications”, “Endorsements”, or “History”.)
      To “Preserve the Title” of such a section when you modify the
      Document means that it remains a section “Entitled XYZ” according
      to this definition.
 
      The Document may include Warranty Disclaimers next to the notice
      which states that this License applies to the Document.  These
      Warranty Disclaimers are considered to be included by reference in
      this License, but only as regards disclaiming warranties: any other
      implication that these Warranty Disclaimers may have is void and
      has no effect on the meaning of this License.
 
   2. VERBATIM COPYING
 
      You may copy and distribute the Document in any medium, either
      commercially or noncommercially, provided that this License, the
      copyright notices, and the license notice saying this License
      applies to the Document are reproduced in all copies, and that you
      add no other conditions whatsoever to those of this License.  You
      may not use technical measures to obstruct or control the reading
      or further copying of the copies you make or distribute.  However,
      you may accept compensation in exchange for copies.  If you
      distribute a large enough number of copies you must also follow the
      conditions in section 3.
 
      You may also lend copies, under the same conditions stated above,
      and you may publicly display copies.
 
   3. COPYING IN QUANTITY
 
      If you publish printed copies (or copies in media that commonly
      have printed covers) of the Document, numbering more than 100, and
      the Document’s license notice requires Cover Texts, you must
      enclose the copies in covers that carry, clearly and legibly, all
      these Cover Texts: Front-Cover Texts on the front cover, and
      Back-Cover Texts on the back cover.  Both covers must also clearly
      and legibly identify you as the publisher of these copies.  The
      front cover must present the full title with all words of the title
      equally prominent and visible.  You may add other material on the
      covers in addition.  Copying with changes limited to the covers, as
      long as they preserve the title of the Document and satisfy these
      conditions, can be treated as verbatim copying in other respects.
 
      If the required texts for either cover are too voluminous to fit
      legibly, you should put the first ones listed (as many as fit
      reasonably) on the actual cover, and continue the rest onto
      adjacent pages.
 
      If you publish or distribute Opaque copies of the Document
      numbering more than 100, you must either include a machine-readable
      Transparent copy along with each Opaque copy, or state in or with
      each Opaque copy a computer-network location from which the general
      network-using public has access to download using public-standard
      network protocols a complete Transparent copy of the Document, free
      of added material.  If you use the latter option, you must take
      reasonably prudent steps, when you begin distribution of Opaque
      copies in quantity, to ensure that this Transparent copy will
      remain thus accessible at the stated location until at least one
      year after the last time you distribute an Opaque copy (directly or
      through your agents or retailers) of that edition to the public.
 
      It is requested, but not required, that you contact the authors of
      the Document well before redistributing any large number of copies,
      to give them a chance to provide you with an updated version of the
      Document.
 
   4. MODIFICATIONS
 
      You may copy and distribute a Modified Version of the Document
      under the conditions of sections 2 and 3 above, provided that you
      release the Modified Version under precisely this License, with the
      Modified Version filling the role of the Document, thus licensing
      distribution and modification of the Modified Version to whoever
      possesses a copy of it.  In addition, you must do these things in
      the Modified Version:
 
        A. Use in the Title Page (and on the covers, if any) a title
           distinct from that of the Document, and from those of previous
           versions (which should, if there were any, be listed in the
           History section of the Document).  You may use the same title
           as a previous version if the original publisher of that
           version gives permission.
 
        B. List on the Title Page, as authors, one or more persons or
           entities responsible for authorship of the modifications in
           the Modified Version, together with at least five of the
           principal authors of the Document (all of its principal
           authors, if it has fewer than five), unless they release you
           from this requirement.
 
        C. State on the Title page the name of the publisher of the
           Modified Version, as the publisher.
 
        D. Preserve all the copyright notices of the Document.
 
        E. Add an appropriate copyright notice for your modifications
           adjacent to the other copyright notices.
 
        F. Include, immediately after the copyright notices, a license
           notice giving the public permission to use the Modified
           Version under the terms of this License, in the form shown in
           the Addendum below.
 
        G. Preserve in that license notice the full lists of Invariant
           Sections and required Cover Texts given in the Document’s
           license notice.
 
        H. Include an unaltered copy of this License.
 
        I. Preserve the section Entitled “History”, Preserve its Title,
           and add to it an item stating at least the title, year, new
           authors, and publisher of the Modified Version as given on the
           Title Page.  If there is no section Entitled “History” in the
           Document, create one stating the title, year, authors, and
           publisher of the Document as given on its Title Page, then add
           an item describing the Modified Version as stated in the
           previous sentence.
 
        J. Preserve the network location, if any, given in the Document
           for public access to a Transparent copy of the Document, and
           likewise the network locations given in the Document for
           previous versions it was based on.  These may be placed in the
           “History” section.  You may omit a network location for a work
           that was published at least four years before the Document
           itself, or if the original publisher of the version it refers
           to gives permission.
 
        K. For any section Entitled “Acknowledgements” or “Dedications”,
           Preserve the Title of the section, and preserve in the section
           all the substance and tone of each of the contributor
           acknowledgements and/or dedications given therein.
 
        L. Preserve all the Invariant Sections of the Document, unaltered
           in their text and in their titles.  Section numbers or the
           equivalent are not considered part of the section titles.
 
        M. Delete any section Entitled “Endorsements”.  Such a section
           may not be included in the Modified Version.
 
        N. Do not retitle any existing section to be Entitled
           “Endorsements” or to conflict in title with any Invariant
           Section.
 
        O. Preserve any Warranty Disclaimers.
 
      If the Modified Version includes new front-matter sections or
      appendices that qualify as Secondary Sections and contain no
      material copied from the Document, you may at your option designate
      some or all of these sections as invariant.  To do this, add their
      titles to the list of Invariant Sections in the Modified Version’s
      license notice.  These titles must be distinct from any other
      section titles.
 
      You may add a section Entitled “Endorsements”, provided it contains
      nothing but endorsements of your Modified Version by various
      parties—for example, statements of peer review or that the text has
      been approved by an organization as the authoritative definition of
      a standard.
 
      You may add a passage of up to five words as a Front-Cover Text,
      and a passage of up to 25 words as a Back-Cover Text, to the end of
      the list of Cover Texts in the Modified Version.  Only one passage
      of Front-Cover Text and one of Back-Cover Text may be added by (or
      through arrangements made by) any one entity.  If the Document
      already includes a cover text for the same cover, previously added
      by you or by arrangement made by the same entity you are acting on
      behalf of, you may not add another; but you may replace the old
      one, on explicit permission from the previous publisher that added
      the old one.
 
      The author(s) and publisher(s) of the Document do not by this
      License give permission to use their names for publicity for or to
      assert or imply endorsement of any Modified Version.
 
   5. COMBINING DOCUMENTS
 
      You may combine the Document with other documents released under
      this License, under the terms defined in section 4 above for
      modified versions, provided that you include in the combination all
      of the Invariant Sections of all of the original documents,
      unmodified, and list them all as Invariant Sections of your
      combined work in its license notice, and that you preserve all
      their Warranty Disclaimers.
 
      The combined work need only contain one copy of this License, and
      multiple identical Invariant Sections may be replaced with a single
      copy.  If there are multiple Invariant Sections with the same name
      but different contents, make the title of each such section unique
      by adding at the end of it, in parentheses, the name of the
      original author or publisher of that section if known, or else a
      unique number.  Make the same adjustment to the section titles in
      the list of Invariant Sections in the license notice of the
      combined work.
 
      In the combination, you must combine any sections Entitled
      “History” in the various original documents, forming one section
      Entitled “History”; likewise combine any sections Entitled
      “Acknowledgements”, and any sections Entitled “Dedications”.  You
      must delete all sections Entitled “Endorsements.”
 
   6. COLLECTIONS OF DOCUMENTS
 
      You may make a collection consisting of the Document and other
      documents released under this License, and replace the individual
      copies of this License in the various documents with a single copy
      that is included in the collection, provided that you follow the
      rules of this License for verbatim copying of each of the documents
      in all other respects.
 
      You may extract a single document from such a collection, and
      distribute it individually under this License, provided you insert
      a copy of this License into the extracted document, and follow this
      License in all other respects regarding verbatim copying of that
      document.
 
   7. AGGREGATION WITH INDEPENDENT WORKS
 
      A compilation of the Document or its derivatives with other
      separate and independent documents or works, in or on a volume of a
      storage or distribution medium, is called an “aggregate” if the
      copyright resulting from the compilation is not used to limit the
      legal rights of the compilation’s users beyond what the individual
      works permit.  When the Document is included in an aggregate, this
      License does not apply to the other works in the aggregate which
      are not themselves derivative works of the Document.
 
      If the Cover Text requirement of section 3 is applicable to these
      copies of the Document, then if the Document is less than one half
      of the entire aggregate, the Document’s Cover Texts may be placed
      on covers that bracket the Document within the aggregate, or the
      electronic equivalent of covers if the Document is in electronic
      form.  Otherwise they must appear on printed covers that bracket
      the whole aggregate.
 
   8. TRANSLATION
 
      Translation is considered a kind of modification, so you may
      distribute translations of the Document under the terms of section
      4.  Replacing Invariant Sections with translations requires special
      permission from their copyright holders, but you may include
      translations of some or all Invariant Sections in addition to the
      original versions of these Invariant Sections.  You may include a
      translation of this License, and all the license notices in the
      Document, and any Warranty Disclaimers, provided that you also
      include the original English version of this License and the
      original versions of those notices and disclaimers.  In case of a
      disagreement between the translation and the original version of
      this License or a notice or disclaimer, the original version will
      prevail.
 
      If a section in the Document is Entitled “Acknowledgements”,
      “Dedications”, or “History”, the requirement (section 4) to
      Preserve its Title (section 1) will typically require changing the
      actual title.
 
   9. TERMINATION
 
      You may not copy, modify, sublicense, or distribute the Document
      except as expressly provided under this License.  Any attempt
      otherwise to copy, modify, sublicense, or distribute it is void,
      and will automatically terminate your rights under this License.
 
      However, if you cease all violation of this License, then your
      license from a particular copyright holder is reinstated (a)
      provisionally, unless and until the copyright holder explicitly and
      finally terminates your license, and (b) permanently, if the
      copyright holder fails to notify you of the violation by some
      reasonable means prior to 60 days after the cessation.
 
      Moreover, your license from a particular copyright holder is
      reinstated permanently if the copyright holder notifies you of the
      violation by some reasonable means, this is the first time you have
      received notice of violation of this License (for any work) from
      that copyright holder, and you cure the violation prior to 30 days
      after your receipt of the notice.
 
      Termination of your rights under this section does not terminate
      the licenses of parties who have received copies or rights from you
      under this License.  If your rights have been terminated and not
      permanently reinstated, receipt of a copy of some or all of the
      same material does not give you any rights to use it.
 
   10. FUTURE REVISIONS OF THIS LICENSE
 
      The Free Software Foundation may publish new, revised versions of
      the GNU Free Documentation License from time to time.  Such new
      versions will be similar in spirit to the present version, but may
      differ in detail to address new problems or concerns.  See
      <https://www.gnu.org/copyleft/>.
 
      Each version of the License is given a distinguishing version
      number.  If the Document specifies that a particular numbered
      version of this License “or any later version” applies to it, you
      have the option of following the terms and conditions either of
      that specified version or of any later version that has been
      published (not as a draft) by the Free Software Foundation.  If the
      Document does not specify a version number of this License, you may
      choose any version ever published (not as a draft) by the Free
      Software Foundation.  If the Document specifies that a proxy can
      decide which future versions of this License can be used, that
      proxy’s public statement of acceptance of a version permanently
      authorizes you to choose that version for the Document.
 
   11. RELICENSING
 
      “Massive Multiauthor Collaboration Site” (or “MMC Site”) means any
      World Wide Web server that publishes copyrightable works and also
      provides prominent facilities for anybody to edit those works.  A
      public wiki that anybody can edit is an example of such a server.
      A “Massive Multiauthor Collaboration” (or “MMC”) contained in the
      site means any set of copyrightable works thus published on the MMC
      site.
 
      “CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0
      license published by Creative Commons Corporation, a not-for-profit
      corporation with a principal place of business in San Francisco,
      California, as well as future copyleft versions of that license
      published by that same organization.
 
      “Incorporate” means to publish or republish a Document, in whole or
      in part, as part of another Document.
 
      An MMC is “eligible for relicensing” if it is licensed under this
      License, and if all works that were first published under this
      License somewhere other than this MMC, and subsequently
      incorporated in whole or in part into the MMC, (1) had no cover
      texts or invariant sections, and (2) were thus incorporated prior
      to November 1, 2008.
 
      The operator of an MMC Site may republish an MMC contained in the
      site under CC-BY-SA on the same site at any time before August 1,
      2009, provided the MMC is eligible for relicensing.
 
 C.1 ADDENDUM: How to use this License for your documents
 ========================================================
 
 To use this License in a document you have written, include a copy of
 the License in the document and put the following copyright and license
 notices just after the title page:
 
      Copyright (C)  YEAR  YOUR NAME.
      Permission is granted to copy, distribute and/or modify this document
      under the terms of the GNU Free Documentation License, Version 1.3
      or any later version published by the Free Software Foundation;
      with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
      Texts.  A copy of the license is included in the section entitled ``GNU
      Free Documentation License''.
 
    If you have Invariant Sections, Front-Cover Texts and Back-Cover
 Texts, replace the “with...Texts.” line with this:
 
      with the Invariant Sections being LIST THEIR TITLES, with
      the Front-Cover Texts being LIST, and with the Back-Cover Texts
      being LIST.
 
    If you have Invariant Sections without Cover Texts, or some other
 combination of the three, merge those two alternatives to suit the
 situation.
 
    If your document contains nontrivial examples of program code, we
 recommend releasing these examples in parallel under your choice of free
 software license, such as the GNU General Public License, to permit
 their use in free software.
