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.

If your Mac has a trackpad, simply control the scroll by a two-finger vertical swipe. It should respond in accordance with the length of the swipe. –  David Carraher Sep 17 '12 at 14:57
@DavidCarraher I do that, but I'd like the option of controlling the presentation while standing away from the computer, hence the presentation remote :). –  JxB Sep 17 '12 at 15:15
