+
+;;; Commentary:
+;;
+;; The main function, `ace-window' is meant to replace `other-window'
+;; by assigning each window a short, unique label.  When there are only
+;; two windows present, `other-window' is called (unless
+;; aw-dispatch-always is set non-nil).  If there are more, each
+;; window will have its first label character highlighted.  Once a
+;; unique label is typed, ace-window will switch to that window.
+;;
+;; To setup this package, just add to your .emacs:
+;;
+;;    (global-set-key (kbd "M-o") 'ace-window)
+;;
+;; replacing "M-o"  with an appropriate shortcut.
+;;
+;; By default, ace-window uses numbers for window labels so the window
+;; labeling is intuitively ordered.  But if you prefer to type keys on
+;; your home row for quicker access, use this setting:
+;;
+;;    (setq aw-keys '(?a ?s ?d ?f ?g ?h ?j ?k ?l))
+;;
+;; Whenever ace-window prompts for a window selection, it grays out
+;; all the window characters, highlighting window labels in red.  To
+;; disable this behavior, set this:
+;;
+;;    (setq aw-background nil)
+;;
+;; If you want to know the selection characters ahead of time, turn on
+;; `ace-window-display-mode'.
+;;
+;; When prefixed with one `universal-argument', instead of switching
+;; to the selected window, the selected window is swapped with the
+;; current one.
+;;
+;; When prefixed with two `universal-argument', the selected window is
+;; deleted instead.
