Which config do I edit to bind Enter to duck? Default.cfg?

Also, what essential command is Enter bound to already? I assume it must be important if you wont let people unbind enter from it. I dont want to be doing that every time I duck, so how do I unbind enter from whatever that is (I cant see it in the config at least)?

And while we are at it, how to you rebind the keybad keys, and what are the names of the specific keys (ie Kp1, KP_1, Kpend, KP_end ?! etc.) And what essential commands are they already bound to?


How bizzare that the game wont let you rebind half your keyboard.
