On Using X w/o the Rodent

Jacobian asks "I'm really sick of my hands acking from typing and using my mouse all day. I would like recommendations on a cool ergonomic keyboard, and a way that I can realistically say goodbye to my mouse once and for all in X. Every WM that I've used extensively has been very unfriendly if you don't use a mouse. Some (fvwm) you can avoid using the mouse most of the time, but eventually there is some focusing problems that make you reach for the rodent once again. Is there a WM in which I would never have to use my mouse?" I've never thought about it before, but having a keyboard friendly WM couldn't hurt. How do the different WMs rate on the various functions that can be accessed from both the mouse and the keyboard? (More)

Which actions cause the most long-term damage to your wrists: Repetitive keyboard use? Or repetitive mouse use? Would a keyboard friendly WM really help those suffering from wrist pain?

On a more personal note, I've found this submission to be rather ironic considering that for the past week, I've had to wear a splint on my wrist, due to an old injury (and not carpal tunnel, thank god!) commited in my reckless youth. So it's interesting that this one came along when it did.
