Too fundamental of a key to even be a combination IMHO. I
terminate each edit operation by it, like a dot at the
end of a sentence, it needs to be a half a second operation so I can spend most
of my time in normal mode.
I just remap Caps Lock
to Esc system wise (a setting in both Linuxes and MacOs) and use both shift for
Caps Lock (setting on Linux, Idk about MacOS)
I have always found the "jk" solution quite elegant although I don't use it
The benefit of using it system wise is that it then works
with all programs that have a vi mode (zsh, gdbtui, etc.)
