I just broke my F5 Key on my already torn-up computer

[Hippo]

I can't crouch in a lot of games because I have no left control D:

Couldn't you customize the controls so alt is used to crouch?

It mainly affects me in TF2 and when I try to change the options in that it freezes for like 2 minutes. I really can't be bothered.

The only other way it affects me is that I have to do right control - alt - delete to get task manager up.
