One of Murphy's Laws of Combat (in all its various incarnations) is: If it's stupid and it works, it isn't stupid.
My pinkies still hurt when I type. It's definitely the typing that's doing it, since my hands get better over the weekends.
So, I'm trying to be an 8-fingered typist, but I figured out that my use of the CTRL keys is killing me, especially when sending IMs (which we tend to do around here).
So, I took off my control keys.
I'll let you know if it's stupid or not.
