Emacs, switch to previous window

Question

In Emacs, C-x o takes me to the next window.

What keyboard macro takes me to the previous window in Emacs?

Answer 1

If you work with multiple emacs windows (>3) a lot and you will want to save some keystrokes add this to your init file and you'll be better off:

(defun frame-bck()
  (interactive)
  (other-window-or-frame -1)
)
(define-key (current-global-map) (kbd "M-o") 'other-window-or-frame)
(define-key (current-global-map) (kbd "M-O") 'frame-bck)

Now just cycle quickly thru the windows with M-o
