Feature request: other-previous-window

Feature request: other-previous-window

[Miguel Guedes]

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)

What about C-- C-x o?  (Or C-u - C-x o, etc.)

It just seemed to me overly complicated for such a simple task.

Why should the inverse of C-x o require twice as effort, when the effort 
required should (IMHO) be exactly the same only having the inverse result?

You might like to try some window-navigation packages like windmove,

I had done but unfortunately windmove  doesn't allow for circular movement
between windows like other-window does.

Yes, that is very inconvenient in windmove.

Shouldn't be too hard to change.

Isn't that windmove-wrap-around?

Phil Hagelberg's excellent Emacs Starter Kit has this key binding for
the reverse operation of C-x o.

(global-set-key (kbd "C-x O") (lambda () (interactive) (other-window -1)))

Of course, you could remove the "&optional" from the signature and
then you'd need to do C-1 C-x o to move forward in the list, with more
symmetric effort. ;-)  Seriously, the reason is that keystrokes in the
global map are a scarce resource.

If you personally have some keystroke you never use, then

C-x ( C-u - C-x 0 C-x ) M-x assign-kbd-macro-to-key RET <KEYSTROKE>

is your friend.

You can also try windresize.el from GNU ELPA.

  M-x windresize RET
  [then `o' will cycle through windows]

HTH,
