I was playing about with my hotkeys in sc2 and I stumbled on a great idea. The idea is making smart hotkeys that do work for you. So the idea that I came up with was something simple and that was binding stuff to qwer per building but that isnt the point I stumbled on a great hotkey that actually comes in handy and that is binding borrow to R.
Why is this smart because when I got lair tech because my keyboard accuracy was pretty low I hit R before I pressed S to spawn larva and got borrow really early every time I got roach. Its insane but really it works pretty nicely.
