Ergonomics: fingers to use to press Cmd and Opt keys at the same time I find myself struggling with keyboard shorts that require pressing CmdOpt at the same time. I have been using my third and fourth fingers on my left hand press Cmd and Opt respectively, but this means for CmdOpts, I have to use my right hand to press s.
I also tried using the thumb but sometimes I miss either the Cmd or Opt.
What is the preferred way to execute such keyboard shortcuts?
When I need to hit command and either control or option,I generally use my left middle and fore fingers, sometimes middle and thumb, sometimes pinky and thumb.

However, it's not especially often I end up needing more than one modifier key at the same time (ie, I usually only need command or option or control with another key - not together).
