actually, xmonobut can be incredibly handy if you *don't* use it in the default manner. "xmonobut -k 67" will make it run so if you hold down the zaurus's "Calendar" button while tapping, you get a right click. pressing, releasing, pressing and holing calendar (like double clicking a mouse) makes it a middle click instead. There is a -m flag so you can assign a dedicated middle button key, but it just seems to make xmonobut glitchy if i use it. if you want to use a different key to modify your clicks, use xev to find out the keycode and do xmonobut -k keycode. hope this helps someone...
