Add keystroke shortcut for Slideshow

I just tripped over GitHub's slideshow capability and I am in Love with it! I would so love to be able to move forwards and backward in a Wiki slideshow with keystrokes. When I use the mouse, I sometimes click in the wrong place and the screen slides away up or down, exposing the implementation. Ugh!

Any suggestions for magic -- Javascript comes to mind -- that can be added to the control buttons to make it possible to move forward and backward in the slides without a mouse would be much appreciated!

(Do I have to rewrite this as a form??)
