;;; wmanip.el --- manipulate windows from the keyboard
;; Copyright (C) Ian Zimmerman, December 2002
;; Terms: GNU General Public License, Version 2
;;; Commentary:
;; This is _not_ a permanent minor mode like, say, Auto
;; Fill, which you turn on and go about your editing. What I wanted to
;; do was: get in through my preferred binding (C-cw), adjust the windows
;; to my liking, and get out with Esc-Esc.
;;; Code:
(defvar wmanip-mode nil
"The global flag for the wmanip minor mode.")
(defun wmanip-mode (&optional arg)
"Set or toggle the wmanip minor mode.
\\<wmanip-mode-map> This mode provides a keyboard interface to the window
manipulation commands {enlarge,shrink}-window{,-horizontally} which is
actually usable. The keybindings for these commands that are built
into Emacs (C-x^, C-x{, C-x}) are terrible because repeating them
means stretching your hands back and forth over the keyboard.
\\[other-window] - Select the ARG'th different window on this frame.
\\[enlarge-window] - Make current window ARG lines bigger.
\\[shrink-window] - Make current window ARG lines smaller.
\\[enlarge-window-horizontally] - Make current window ARG columns wider.
\\[shrink-window-horizontally] - Make current window ARG columns narrower."
