Some time ago I decided to bind f6 to other-window. I lived happily with that binding, but then something struck me. My f6 key was completely useless when I had only one window in the current frame. What a waste! So, I decided to code this.
(defun other-window-or-switch-buffer () "Call `other-window' if more than one window is visible, switch to next buffer otherwise." (interactive) (if (one-window-p) (switch-to-buffer nil) (other-window 1))) (global-set-key (kbd "<f6>") #'other-window-or-switch-buffer)
Now f6 cycles through my most recently used two buffers if I have only one window. (This partially supersedes my other command described here, so maybe I’ll bind C-z b without the prefix argument to something else – we’ll see.)
