Left handed player hotkeys

As a left handed player i use my right hand on the keyboard. But lately i feel like my current hotkey setup is not good enough anymore. A lot of hotkeys / button combinations are just to hard to find quick and consitently.

Are there any left handed players above 1200 elo with some tips i can use?

How do you guys use select all ranges / stables for example? I mostly use DE hotkeys but changed this to ctrl+q/w/e for range/stable/rax

I couldn't find any topics about this subject, but i assume is has to be something Lefty's like us have to be creative with...
