I haven't looked at the schematic for the keyboard, but it appears that
the mouse port on the AT&T 6300 KB is simply paralleling the arrow keys.
There's some additional logic involved, since you can redefine the mouse
scan rate and remap the buttons, but basically what you've got is a
rolling arrow key.

One of the projects on my todo list is to write a snippet of code to
slow the bloody thing down a bit.
