Map a key to switch between my favorite weapons for each class?
When I play Team Fortress 2 and want to switch weapons I have to select one using my the keyboard's number keys (1, 2, 3, ...) and press fire button on the mouse to switch to that weapon. Alternatively I can select a weapon using the mouse's scroll wheel and then pressing the fire button to switch. I find this very annoying since it takes too much time using this method. Is there a setting that makes the game switch weapons immediately when I press a number key or scroll?
