[ltp] Thinkpad key removal

[cr]

Please excuse the slight OT, but can anyone point me to a link that describes 
how to remove (without damage) a key from a Thinkpad keyboard (specifically, 
the left mouse key on a R40).   Or does the whole keyboard have to come off?

(I made the mistake of putting a casino game on the Windows partition for my 
wife, and after much pounding of the left mouse key, I think the little 
rubber spring's collapsed.   I have a new key and spring, I just need to fit 
it).
