10.2 Documentation for a Key
The help commands to get information about a key sequence are C-h c (describe-key-briefly
) and C-h k (describe-key
).
C-h c key displays in the echo area the name of the command that key
is bound to. For example, C-h c C-f displays ‘forward-char
’.
C-h k key is similar but gives more information: it displays a help buffer containing the command’s documentation string, which describes exactly what the command does.
C-h K key displays the section of the Emacs manual that describes the command corresponding to key
.
C-h c, C-h k and C-h K work for any sort of key sequences, including function keys, menus, and mouse events (except that C-h c ignores mouse movement events). For instance, after C-h k you can select a menu item from the menu bar, to view the documentation string of the command it runs.
C-h w command RET lists the keys that are bound to command
. It displays the list in the echo area. If it says the command is not on any key, that means you must use M-x to run it. C-h w runs the command where-is
.
