I could bind crouch and sprint to x and c, too, but I'd like to keep a reachable bind for buying rifle and ckit. Since I put sprint/sneak on SHIFT I could make SHIFT+x rifle and SHIFT+c ckit. So that would leave us with SHIFT and x for sprint and CTRL, ALT and c for crouch/wallwalk.
kharnov, while building binds are comfortable I think that buy binds are of greater importance for newbes as the build menu is far easier to use than the buying dialog, where you have to manually sell stuff first.
freem, I guess we could ship different localized layouts that can be parsed via the exec command or automatically later on. Feel free to make a flexible, beginner friendly setting for french keyboards.
