Maybe someone who only used csh? I can’t remember if ^a is a default in that shell. I thought it started with ksh or bash.
ETA: just looked it up and I’m dumb. Comes from emacs (of course) and looks like it was introduced in bash. I guess I could claim ignorance, being a VI man, but I actually knew at some point that it came from emacs. I think I can count on 1 hand the number of times I’ve used emacs
Unless you’re in a default screen session (I always thought ^A was such a dumb default for screen to use).
Screen must have been written by someone who wasn’t familiar with the shell. It’s the only logical explanation.
