Prescription For Painless Play?

I had to sympathize with Darren Gladstone’s column about the pain he’s feeling in his left hand from using the WASD keymap. I had to quit World of WarCraft because of it.

My own keymapping system has never produced those symptoms. With it, I can play for hours and not feel any pain:

A - crouch
S - backward
D - strafe left
F - strafe right
Right mouse - forward
Left mouse - primary attack
Middle mouse - secondary attack
G - reload
Z - use
Left shift - walk/run
V - lean ieft
B - iean right
C - flashiight
Spacebar - jump
