Friend was messing with bind commands to make the mouse wheel and jump work together; now when I use volume control on my laptop commands in CSS are also used: Fn+Up (for volume up) are making me "buy" (such as "b" would) in game. Fn+Down (for volume down) are making me do team commands. F5 no longer works for screen shots (even though in option > controls it says F5 is for screen shots) I tried the unbindall in ~command prompt and loaded default keys on options but problem is still not resolved. It doesn't ruin the game but it is annoying when I want to turn the volume up or down in the middle of the game. Any ideas how to undo this?
