Alert ping settings on a Macbook

Okay so i used to play on windows and i could hold control and left click +drag in one of 4 directions for the alert ping (danger, missing enemy, assist and on my way pings) and now that i am playing on the macbook i cannot reach the control button so easily so i was wondering if anyone knows how i can change the settings so that the apple command key acts as the control key in LoL. Also, please don't wast your time with hating on macs and apple products. no body cares and ill just skip the comment and move on. Thanks.
