I've started using The Rememberance Agent within Emacs on my MacBook. This means that I get a "window" (in Emacs' parlance, actually a buffer within my overall Emacs window) that displays a list of files most relevant to the text I am currently editing.

The code below will skip over the remembrance output when switching between buffers:

 
(defun bh-other-window ()
  (interactive)
  (other-window 1)
  (if (string-equal (buffer-name (window-buffer)) "*remem-display*")
      (other-window 1)
    )
  )
(global-set-key (kbd "C-x o") 'bh-other-window)
