I think the keyboard example hints for something bigger. Yes it's a small example.But it may allow you to stay in the flow(and optimal focus) better than someone who'se looking around menus. And the effect is probably non-linear to effort. And it accumulates. Now every month you get to learn more/better than the other guy. So yes, similarly minor things can be huge multipliers , like you say.
