Feature request: other-previous-window

[Miguel Guedes <miguel.a.guedes@gmail.com>]

This is a request proposal for a very simple feature: the twin brother 
of other-window.

I often keep multiple windows open in my always maximized Emacs frame, 
rarely ever less than 2 and usually 3 windows tiled vertically. Having 
an inverse to other-window would be a blessing as I often need to jump 
from a window in one extreme to the other (skip the window in the 
middle.) When moving forwards (other-window), this is not a problem. 
However, sometimes I find myself at the leftmost window in need of 
moving to the rightmost window.

In other words, if in a given instance of Emacs there are windows A B C, 
being able to quickly and effortlessly jump from A to C would be great.

Being a complete newbie to ELISP I don't know if the following code is 
up to ELISP standards practiced by the Emacs devs but I suppose it is a 
starting point at least:


(defun other-previous-window (count &optional all-frames)
   (interactive "p")
   (other-window (* count -1) all-frames))

(define-key ctl-x-map "p" 'other-previous-window)
