Key Binding Problem.

Well, I started playing CF days ago, and everytime I log I have to set Walk binding (Shift) to the same key, but it's called "Mayúsculas" here and jump binding (Spacebar) to the same key but it's called "Barra Espaciadora" here... because I speak spanish.
I have no problems with that, I mean it's not hard to fix it. But, I can't change (Tab) Key to see scoreboard... it must be something like "Tabulador" here and I can't change it to tabulador.
