Finally, another user that doesn't drink the mouse Kool-Aid; although
I use the mouse a moderate amount, using the mouse for cursor
positioning while editing code is indeed a terrible waste. I've looked
at the papers linked from the Plan 9 wiki about speed of mouse vs.
keyboard, and while it may be faster to go from point A to point B
using the mouse when A and B are far apart, the context switch and the
fact that often you're not moving that far kinda makes the point void.
