|
|
|
23 ;;
|
|
|
24 ;; Defines button one to hide blocks when clicked on outline-up-arrow
|
|
|
25 ;; and expand blocks when clicked on outline-down-arrow. Features are
|
|
|
26 ;; activated when outline-minor-mode or outline-mode are turned
|
|
|
27 ;; on. There is also a menu for each glyph on button 3.
|
|
|
28 ;;
|
|
|
29 ;; To use put:
|
|
|
30 ;; (require 'outl-mouse)
|
|
|
31 ;; in your .emacs file.
|
|
|
32 ;;
|
|
|
33 ;; If you use func-menu all the time and want outl-mouse on all the
|
|
|
34 ;; time as well then put:
|
|
|
35 ;; (setq outline-sync-with-func-menu t)
|
|
|
36 ;; outlining will then be turned on when func-menu is. Note that this
|
|
|
37 ;; requires a patch to func-menu 2.16 (in 19.10) to work:
