`v`: support ctrl-[ #544

Closed ekipan closed 1 year ago

ekipan commented 1 year ago

In PC terminal emulators ctrl-[ sends the same keycode as Esc, $1b, so you can exit vi's insert mode without having to reach up for the escape key. DurexForth's key (and so presumably the C64 routines it uses) gives the same keycode so it could be nice for v to support for VICE users where [ is unshifted. If I understand correctly the relevant source is v.fs line 300.

Indeed, cc65 supports this too https://cc65.github.io/doc/c64.html#ss9.1

If it is a problem of VICE keyboard ergonomics, why not just change the VICE keyboard mapping so that it suits you better? It is eminently configurable.

ekipan commented 1 year ago

It's not any more ergonomic to press Ctrl-[ vs. the default Shift-~ for <-. Just another keystroke to share in common with vi, if you care about that. I'm not too concerned myself, wouldn't bother me if it were closed rejected.

I'd be curious to know how many vi users even know this is possible.

OK.... Well, I do not think there is enough RAM to add even 1% of vi keypresses, so so far, I try to stick to the essentials (at least for me), maybe it is already too much.

I had no idea about Ctrl+[ , I will try to remember that one and use it in everyday life. Thank you for the tip!

It might rely on an American English keyboard layout? Just FYI.
