|
||
|
||
;;; Commentary:
|
||
|
||
;; This file defines a menu of faces (bold, italic, etc) which allows you to
|
||
;; set the face used for a region of the buffer. Some faces also have
|
||
;; keybindings, which are shown in the menu.
|
||
;;
|
||
;; The menu also contains submenus for indentation and justification-changing
|
||
;; commands.
|
||
|
||
;;; Usage:
|
||
;; Selecting a face from the menu or typing the keyboard equivalent will
|
||
;; change the region to use that face. If you use transient-mark-mode and the
|
||
;; region is not active, the face will be remembered and used for the next
|
||
;; insertion. It will be forgotten if you move point or make other
|
||
;; modifications before inserting or typing anything.
|
||
;;
|
||
;; Faces can be selected from the keyboard as well.
|
||
;; The standard keybindings are M-o (or ESC o) + letter:
|
||
;; M-o i = "set italic", M-o b = "set bold", etc.
|
||
|
||
;;; Customization:
|
||
;; An alternative set of keybindings that may be easier to type can be set up
|
||
;; using "Alt" or "Hyper" keys. This requires that you either have or create
|
||
;; an Alt or Hyper key on your keyboard. On my keyboard, there is a key
|
||
;; labeled "Alt", but to make it act as an Alt key I have to put this command
|
||
;; into my .xinitrc:
|
||
;; xmodmap -e "add Mod3 = Alt_L"
|
||
;; Or, I can make it into a Hyper key with this:
|
||
;; xmodmap -e "keysym Alt_L = Hyper_L" -e "add Mod2 = Hyper_L"
|
||
;; Check with local X-perts for how to do it on your system.
|
||
;; Then you can define your keybindings with code like this in your .emacs:
|
||
;; (setq facemenu-keybindings
|
||
;; '((default . [?\H-d])
|
||
;; (bold . [?\H-b])
|
||
;; (italic . [?\H-i])
|
||
;; (bold-italic . [?\H-l])
|
||
;; (underline . [?\H-u])))
|
||
;; (facemenu-update)
|
||
;; (setq facemenu-keymap global-map)
|
||
;; (define-key global-map [?\H-c] 'facemenu-set-foreground) ; set fg color
|
||
;; (define-key global-map [?\H-C] 'facemenu-set-background) ; set bg color
|
||
;;
|
||
;; The order of the faces that appear in the menu and their keybindings can be
|
||
;; controlled by setting the variables `facemenu-keybindings' and
|
||
;; `facemenu-new-faces-at-end'. List faces that you want to use in documents
|
||
;; in `facemenu-listed-faces'.
|
||
|
||
;;; Known Problems:
|
||
;; Bold and Italic do not combine to create bold-italic if you select them
|
||
;; both, although most other combinations (eg bold + underline + some color)
|
||
;; do the intuitive thing.
|
||
;;
|
||
;; There is at present no way to display what the faces look like in
|
||
;; the menu itself.
|
||
;;
|
||
;; `list-faces-display' shows the faces in a different order than
|
||
;; this menu, which could be confusing. I do /not/ sort the list
|
||
;; alphabetically, because I like the default order: it puts the most
|
||
;; basic, common fonts first.
|
||
;;
|
||
