i need some serious help with making custom hotkeys I read all but either it just doesn't work on my pc or just i do something wrong which i doubt... first of all when i press ctrl and after D for ex i mean D and then control as in instruction and i tried other ways as well but nothing seems to work( is there a manual way to add keys to the dat file? Or that readme file? or any other??@Caliber

many thanks in advance
