Good to know! I have a Twiddler one-handed keyboard with a poor pointer control 
stick, but at least it has 3 buttons. I should try using it with a mouse like 
this. I've also enjoyed playing Minecraft with the mouse buttons remapped to 
keys. It's basically the same thing: movement right-handed, buttons 
left-handed. 

My major problem with mouse or keyboard is arm support. I'm "tall sitting 
down", so I need armrests and a desk much higher than average. I remember a 
normal mouse being fine so long as the desk was high enough.
