You can use xautomation to send keystrokes.

I have written an emacs interface for xte. You can find it here:
http://www.xsteve.at/prg/emacs/xte.el

I have a similar demand. The following two functions jump to the
recent window, send prior/next and switch back to the actual one:

(defun xte-recent-win-page-up ()
  (interactive)
  (xte [(hyper ?k) ?k prior sleep (hyper ?k) ?k]))

(defun xte-recent-win-page-down ()
  (interactive)
  (xte [(hyper ?k) ?k next sleep (hyper ?k) ?k]))


Note: I use hyper ?k ?k to switch to the most recent window.
