;; Keywords: faces
;; 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. Faces with names beginning with
-;; "fg:" or "bg:", as in "fg:red", are treated specially.
-;; Such faces are assumed to consist only of a foreground (if "fg:") or
-;; background (if "bg:") color. They are thus put into the color submenus
-;; rather than the general Face submenu. These faces can also be
-;; automatically created by selecting the "Other..." menu items in the
-;; "Foreground" and "Background" submenus.
+;; keybindings, which are shown in the menu.
;;
;; The menu also contains submenus for indentation and justification-changing
;; commands.
;; 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.
+;; Faces can be selected from the keyboard as well.
