Thank you! Your code is very helpful. Now to the questions:
I can't find this documented anywhere. Specifically, the token "ScrollPageNext" does not appear in the "Wolfram Documentation".
If I put in your code, by itself, then, as advertised, the right arrow key advances my slides in a Mathematica slide show, and not just in my notebook. Nice!
To try to get the left arrow key to be associated with backing up one slide I guessed at the second command below. It works great but it disables the right arrow key ... ! :-)
I would love to use these and other features if they are explained anywhere.
Before I bother Support, I thought I'd ask you again.
Thank you!
