U have to change it in game - every program start in default keyboard layout (which is in your case different than US). Btw recomend u customkeys (custom keys are really simple to use and u wont have problem with this coz every hero use QWER skill layout).
F*** all custom keys, keys tool or other shit programs to improve ur gameplay in dota. Ur all cowards using it and I doubt about if that shouldnt be taken as MAP hack..Map hack is program that helps u ingame... and custom key program also helps u ingame.Whats next? program that will automaically follow enemies? program that will buy for u items by pressing one key?. Hate and Pain for all custom key users.
