Keybinding for AutoAttack

Currently auto attack can be enabled or disabled in the options menu while in game. I would love to be able to bind this action to a hotkey so as not to have to bring up the options menu to swap every time. Depending on the champion and timeline of the game, sometimes i like to have it on, and sometimes off. Usually early lane phase i prefer autoattack off, but there are times when just clearing a wave with an adc late game, you just want to stand there and let autoattack take care of the minion clear. Please give us a toggle option.

Thanks!
