Optional KEYMAP is the default keymap bound to the mode keymap.
If non-nil, it should be a variable name (whose value is a keymap),
or an expression that returns either a keymap or a list of
- arguments for `easy-mmode-define-keymap'. If you supply a KEYMAP
- argument that is not a symbol, this macro defines the variable
- MODE-map and gives it the value that KEYMAP specifies.
+ (KEY . BINDING) pairs where KEY and BINDING are suitable for
+ `define-key'. If you supply a KEYMAP argument that is not a
+ symbol, this macro defines the variable MODE-map and gives it
+ the value that KEYMAP specifies.
BODY contains code to execute each time the mode is enabled or disabled.
It is executed after toggling the mode, and before running MODE-hook.
:variable PLACE The location to use instead of the variable MODE to store
the state of the mode. This can be simply a different
named variable, or a generalized variable.
- PLACE can also be of the form \(GET . SET), where GET is
+ PLACE can also be of the form (GET . SET), where GET is
an expression that returns the current state, and SET is
a function that takes one argument, the new state, and
sets it. If you specify a :variable, this function does
For example, you could write
(define-minor-mode foo-mode \"If enabled, foo on you!\"
- :lighter \" Foo\" :require 'foo :global t :group 'hassle :version \"27.5\"
+ :lighter \" Foo\" :require \\='foo :global t :group \\='hassle :version \"27.5\"
