Typing eza is a pretty horrible three character combination on a qwerty keyboard. One advantage of ls is it’s a lightning fast set of key strokes. I guess you can alias, but that’s kind of weird (compatibility, etc).
I also have sl installed to encourage accuracy when running it…
I'm not sure the meaning behind the name, but maybe they should have picked `eya` instead, that's nice and satisfying rather than the double pinky move :D
