Dude, did you even read my previous post? I, for example, have an Azerty keyboard which means I control movement with ZQSD instead of WASD (click here). Several other countries use their own layouts as well.

Anyway, include the key definitions in every message sent to the player. So instead of writing 'Press W to do stuff' you write 'Press ~k~~GO_FORWARD~ to do stuff'.
