02d709c0 | 26 | ;; Provides `tool-bar-mode' to control display of the tool-bar and |
ec7f4585 DL |
27 | ;; bindings for the global tool bar with convenience functions |
28 | ;; `tool-bar-add-item' and `tool-bar-add-item-from-menu'. | |
29 | ||
9a4b8870 | 30 | ;; The normal global binding for [tool-bar] (below) uses the value of |
c129b5ef DL |
31 | ;; `tool-bar-map' as the actual keymap to define the tool bar. Modes |
32 | ;; may either bind items under the [tool-bar] prefix key of the local | |
33 | ;; map to add to the global bar or may set `tool-bar-map' | |
b28e72df | 34 | ;; buffer-locally to override it. (Some items are removed from the |
9a4b8870 | 35 | ;; global bar in modes which have `special' as their `mode-class' |
b011dcb0 | 36 | ;; property.) |
