What?? I've gone the opposite direction on mousing.
What does B/E stand for?
They are the utility scripts to start an editor window in Acme. B is async whereas E is sync (so that it can be used for the EDITOR env variable for software like git).
Not sure what they stand for for sure. E is probably editor. B might be buffer?
Finally, I've come to appreciate using a mouse with my editor. Until I completely got rid of using most keyboard shortcuts (other than the most basic ones), I didn't realize how much cognitive taxes I was paying to retain and context-switch among different families of keyboard shortcuts. Mousing is so much more uniform.
