I play RTSs (Starcraft 2, specifically) and now realize that I want to use more than the 1 - 5 digits to bind my army / buildings / etc.
I cannot precisely hit the 7 - 0 (neither Ctrl + 7 - 0 nor Shift + 7 - 0) keys without looking on the keyboard (my right hand controls the mouse, of course).
Do you know an easy way to hit 7,8,9,0 with the left hand?
Is there some mark that my hand could use (e.g. the right Ctrl) or something else?
I don't want to buy any additional device. My question is all about behavior, not environment. Plus, you probably know that pro-gamers use a normal keyboard and are totally fine with it.
For example, right now I realize that if I rotate the keyboard clockwise a little, access to 7 - 0 becomes easier.
