Thanks, Bill. Despite the showleys episode, I have managed to assign
functionality to a scrollbar on my A4 keyboard. When I scroll up, I
have assigned key code 103 (up arrow key) and when I scroll down,
keycode 108 (down arrow key). Which work great, but there is a flaw!
The scroll sends the press command, but not the release command! So if
i start scrolling, it doesn't stop! I'm still squeezing google for the
solution to this, but I haven't found any other cases of this, much
less any solutions. If you could point me in the right direction, I
would most appreciate it.

The keyboard is an A4 RFKB-25 model: wireless multimedia keyboard that
came with a wireless optical mouse. KDE 3.4 was nice enough to
recognize the volume keys and tie them into the system volume.
However, the scroll wheel on the keyboard is useless in graphical mode
(F7), and throws a request to set it in console mode (F1-F6). The
scroll wheel on the mouse works fine.

I'd love to get that scroll wheel on the keyboard working as pretty
much the only thing that I do with the mouse is scroll- I think that
the mouse is a horrible human interface device for text-based tasks.
