How to bindkey Ctrl-[

How to bindkey Ctrl-[

[Thomas Lauer]

I want to bind Ctrl-[ to the set-mark-command widget. Naive first try
was this:

bindkey "^[" set-mark-command

but that binds the widget to Esc (which is indeed "^["). I've tried
various ideas but no joy.

Is that even possible with my terminal/zsh config?

The simple answer is no --- they are both character 27 in a stream of
characters, so the shell can't tell them apart.

A bit of terminal wizardry to make one look different might be possible,
but 1. that's terminal specific 2. you're going to have to do it in such a
way that it doesn't confuse other utilities 3. if you're going that way
you're probably better grabbing a function key and using that, which
can be done by a shell binding (there are guides to this around somewhere).

Yeah, I thought as much. No biggie really, I have enough other availabe
bindings.
