Thanks for this Michael, I now have -

--8<---------------cut here---------------start------------->8---
#+begin_src emacs-lisp
(defun clear-kill-ring ()
(interactive)
  "Clear the kill ring variable"
  (setq kill-ring nil))
(global-set-key (kbd "s-/") 'clear-kill-ring)
#+end_src
--8<---------------cut here---------------end--------------->8---

And have restarted emacs several times, but if I do a "s-." before hand
I can see several items on the kill-ring. So I then do "s-/" to clear
the kill-ring, and if I then do a further "s-." it shows that there
still remains the same items on the kill-ring, i.e. nothing has changed!
Or, IOW, the function isn't working!

So I'm back to my original question, what do I have to do to get it
working please?

Thanks
Sharon.
