;; This is actually useful when you are running X11 locally, but is
;; working on remote machine over a modem line or through a gateway.
;; It works by translating xterm escape codes into generic emacs mouse
;; events so it should work with any package that uses the mouse.

mouse functionality for such clicks is still available by holding
