I have a presentation remote that allows me to advance Mathematica slides when in the SlideShow environment. The control sends a page down key.
Some of my slides extend below the screen window, and page down scrolls a page at a time.
Is there a way to change the scroll rate associated with a page down key-stroke? I'd like to advance the slides by half a page at a time, or a quarter, for example, or even cell-by-cell.
The notebook options associated with ScrollingOptions seem not to control what I need.
My system is MacOSX, running Mathematica 8.0.4.
