The brain is weird. In the beginning of time, I worked on MsDOS. Then Windows came, but our software still run in DOS. To make a DOS terminal under Windows "full screen" (text mode, in reality), you pressed Alt+Enter. One hundred years later, in my Plasma DE on FreeBSD, my shortcut to maximize a Window is Super+F, but many times my brain thinks Alt+Enter and then corrects itself to Super+F.
Muscle memory is a powerful thing, and muscle memory in the hands for computer use is no exception.
That is one reason why 30 years of Emacs use and customization can make you very effective. Same for vi I assume.
The Unix commandline as well. I cringe when I see people do clickibunti to move a few files around when I would have finished 3 times over already.
