Hmm, this is basically pointing out that power users take the time to learn the craft and make shortcuts. I learned all this stuff not because of Starcraft but because mousing around a 21" screen (which was amazing back in 2007) started giving me RSI.

Funnily enough, a lot of designers tend not to bother with the shortcut stuff, arguably as they don't tend to be doing it day-in day-out.

On the other hand, an illustrator colleague knows all the shortcuts as well as I do (related: the one peeve I had with the near-future tech of Charlie Brooker's 'Be Right Back' ep of Black Mirror was this exact scenario, where an illustrator is using a highly gestural interface to do work. Her whole arms would be aching after just a few hours!)
