Is there easy way to use all digit buttons with left hand

keyboard

Intro
I play RTS (starcraft 2 specifically) and now realize that I want to use more then 1..5 digits to bind my army / buildings / etc.

Problem
I cannot precisely hit 7..0 (neither ctrl+7..0 nor shift+7..0) keys without looking on the keyboard (my right hand controls the mouse of course)

Question
Do you know a way to easy hit 7,8,9,0 with left hand? Is there some mark that my hand could use (i.e. right ctrl) or something else?

edit
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 normal keyboard and totally fine with it.
i.e. right now I realize that if I rotate keyboard clockwise a little then access to 7..0 becomes easier.

Best Answer

I have 6 and 7 remapped to F2 and F3 for my production buildings and main bases. If you have all your production on F2 you can just tab through them to select the different types.

Also, if you're Protoss you can just hit W to select all warp gates.
