;;; Commentary:
|
|
|
|
;; Provides `tool-bar-mode' to control display of the tool-bar and
|
|
;; bindings for the global tool bar with convenience functions
|
|
;; `tool-bar-add-item' and `tool-bar-add-item-from-menu'.
|
|
|
|
;; The normal global binding for [tool-bar] (below) uses the value of
|
|
;; `tool-bar-map' as the actual keymap to define the tool bar. Modes
|
|
;; may either bind items under the [tool-bar] prefix key of the local
|
|
;; map to add to the global bar or may set `tool-bar-map'
|
|
;; buffer-locally to override it. (Some items are removed from the
|
|
;; global bar in modes which have `special' as their `mode-class'
|
|
;; property.)
|
|
|
|
;; Todo: Somehow make tool bars easily customizable by the naive?
|
|
|
|
;;; Code:
|
|
|
|
;; The autoload cookie doesn't work when preloading.
|
|
;; Deleting it means invoking this command won't work
|
|
;; when you are on a tty. I hope that won't cause too much trouble -- rms.
