     49 ;;; Commentary:
     50 
     51 ;; Magit is a text-based Git user interface that puts an unmatched focus
     52 ;; on streamlining workflows.  Commands are invoked using short mnemonic
     53 ;; key sequences that take the cursor’s position in the highly actionable
     54 ;; interface into account to provide context-sensitive behavior.
     55 
     56 ;; With Magit you can do nearly everything that you can do when using Git
     57 ;; on the command-line, but at greater speed and while taking advantage
     58 ;; of advanced features that previously seemed too daunting to use on a
     59 ;; daily basis.  Many users will find that by using Magit they can become
     60 ;; more effective Git user.

    254   "Which set of key bindings to add to the global keymap, if any.
    255 
    256 This option controls which set of Magit key bindings, if any, may
    257 be added to the global keymap, even before Magit is first used in
    258 the current Emacs session.
    259 
    260 If the value is nil, no bindings are added.
    261 
    262 If `default', maybe add:
    263 
    264     C-x g     `magit-status'
    265     C-x M-g   `magit-dispatch'
    266     C-c M-g   `magit-file-dispatch'
    267 
    268 If `recommended', maybe add:
    269 
    270     C-x g     `magit-status'
    271     C-c g     `magit-dispatch'
    272     C-c f     `magit-file-dispatch'
    273 
    274     These bindings are strongly recommended, but we cannot use
    275     them by default, because the \"C-c <LETTER>\" namespace is
    276     strictly reserved for bindings added by the user.
    277 
    278 The bindings in the chosen set may be added when
    279 `after-init-hook' is run.  Each binding is added if, and only
    280 if, at that time no other key is bound to the same command,
    281 and no other command is bound to the same key.  In other words
    282 we try to avoid adding bindings that are unnecessary, as well
    283 as bindings that conflict with other bindings.
    284 
    285 Adding these bindings is delayed until `after-init-hook' is
    286 run to allow users to set the variable anywhere in their init
    287 file (without having to make sure to do so before `magit' is
    288 loaded or autoloaded) and to increase the likelihood that all
    289 the potentially conflicting user bindings have already been
    290 added.
    291 
    292 To set this variable use either `setq' or the Custom interface.
    293 Do not use the function `customize-set-variable' because doing
    294 that would cause Magit to be loaded immediately, when that form
    295 is evaluated (this differs from `custom-set-variables', which
    296 doesn't load the libraries that define the customized variables).
    297 
    298 Setting this variable has no effect if `after-init-hook' has
    299 already been run."
