Cycle - Wanting to add keyboard pause

Cycle - Wanting to add keyboard pause

Hello,

I have got the following code:

What I would like to do is enable it so when the space bar is pressed - the slideshow stops.  When is is pressed again the slideshow resumes.  I have googled and have not come across anything like what I am looking for.
  1. $(document).ready(function() {
        $('.slideshow').cycle({
            fx: 'fade' // choose your transition type, ex: fade, scrollUp, shuffle, etc...
        });
    });
