buffer-move

This file is for lazy people wanting to swap buffers without typing C-x b on each window. This is useful when you have :

+--------------+-------------+
|              |             |
|    #emacs    |    #gnus    |
|              |             |
+--------------+-------------+
|                            |
|           .emacs           |
|                            |
+----------------------------+

and you want to have :

+--------------+-------------+
|              |             |
|    #gnus     |   .emacs    |
|              |             |
+--------------+-------------+
|                            |
|           #emacs           |
|                            |
+----------------------------+

With buffer-move, just go in #gnus, do buf-move-left, go to #emacs (which now should be on top right) and do buf-move-down.

To use it, simply put a (require 'buffer-move) in your ~/.emacs and define some keybindings. For example, i use :

(global-set-key (kbd "<C-S-up>")     'buf-move-up)
(global-set-key (kbd "<C-S-down>")   'buf-move-down)
(global-set-key (kbd "<C-S-left>")   'buf-move-left)
(global-set-key (kbd "<C-S-right>")  'buf-move-right)

By default the point will switch along with the moving buffer, if you want the point to stay (as vim switches) you can set buffer-move-stay-after-swap to a non-nil value like so:

(setq buffer-move-stay-after-swap t)

Alternatively, you may let the current window switch back to the previous buffer, instead of swapping the buffers of both windows. Set the following customization variable to 'move to activate this behavior:

(setq buffer-move-behavior 'move)
