I have recently purchased the game and after starting it up I could not switch between weapons and prone/chat was inverted due to the nature of windows keyboard language. I am using Czech keyboard layout which causes my weapon buttons to be [+,ě,š,č,ř] instead of [1,2,3,4,5]. It would be awesome if the game could detect this as many other titles don't require you to change your binds and simply work and won't display the ingame button to be + and simply say 1.
