In Emacs, what is the opposite function of other-window (C-x o)? [duplicate]

Answer 1

Put this in your .emacs, and bind it to whatever key you like

(defun back-window ()
  (interactive)
  (other-window -1))

Answer 2

A slightly less annoying shortcut available by default isC-- C-x o. That way you don't have to switch between Meta and Control while typing the prefixes.

Answer 3

Different from what you asked for, but the windmove package lets you move between windows according to their relative screen locations, which can be much easier than repeatedly doing C-x o.

Answer 4

Instead of C-u -, you can also give a negative prefix argument with just M-- (Meta-Minus) , i.e. switch to previous window with M-- C-x o.

Answer 5

Provide a negative argument with C-u - ("Control+U" then "minus"), or even more simply C-- ("Control minus").

• Move to previous window: C-- C-x o
• Move to previous frame: C-- C-x 5 o

From code, (other-window -1) or (other-frame -1) will do the same thing.

Check out the help for the key you want to reverse (e.g. C-h k C-x o to show help for C-x o) and if it says "A negative argument..." you know you can use C--.

Answer 6

This is an old post, but I just wondered the same. It seems there now is a function for this in Emacs: previous-multiframe-window.

I have it bound to C-x O, as in uppercase letter o. Now I just throw in shift when I want to go backwards.

(global-set-key (kbd "C-x O") 'previous-multiframe-window)
