yeah, like normal binding options, for example if you want to move camera ingame with buttons and same time be ready to press Attack at that moment with same hand while other hand is aiming all the time at some place, i think it would be really helpful option

hmm... a simple binding, for example you see one as "Attack" and next to it a small box which you click on, and you get avaible list of buttons to choose from, like Q (yea and Q's command could be replaced on other button then like Z).
sorry for bad english but this is still easy to understand, isnt it?
