 ;;; Commentary:
 
 ;; The `which-key' mode displays the key bindings following your
 ;; currently entered incomplete command (a prefix) in a popup.  For
 ;; example, after enabling the minor mode if you enter C-x and wait for
 ;; the default of 1 second the minibuffer will expand with all of the
 ;; available key bindings that follow C-x (or as many as space allows
 ;; given your settings).
 ;;
 ;; This includes prefixes like C-x 8 which are shown in a different
 ;; face.

 \(MATCH CONS . REPLACEMENT\).
 
 The MATCH CONS determines when a replacement should occur and
 REPLACEMENT determines how the replacement should occur.  Each may
 have the format \(KEY REGEXP . BINDING REGEXP\).  For the
 replacement to apply the key binding must match both the KEY
 REGEXP and the BINDING REGEXP.  A value of nil in either position
 can be used to match every possibility.  The replacement is
 performed by using `replace-regexp-in-string' on the KEY REGEXP
 from the MATCH CONS and REPLACEMENT when it is a cons cell, and
 then similarly for the BINDING REGEXP.  A nil value in the BINDING
 REGEXP position cancels the replacement.  For example, the entry
 
 \(\(nil . \"Prefix Command\"\) . \(nil . \"prefix\"\)\)
 
 matches any binding with the descriptions \"Prefix Command\" and
 replaces the description with \"prefix\", ignoring the
 corresponding key.
 
 REPLACEMENT may also be a function taking a cons cell
 \(KEY . BINDING\) and producing a new corresponding cons cell.
 
 If REPLACEMENT is anything other than a cons cell \(and non nil\)
 the key binding is ignored by which-key.
