Terminal's escape sequences should start with ESC. Also, is `C-x @ s ESC` presumed to be `s-ESC` or is it `super` applied to the escape sequence that this ESC starts? I mean, our encoding is poor (since it doesn't allow combining several `C-x @` together, for example), but it can be justified by the desire to cater to the most common case without unduly burdening the user how has to type those keys. But for a terminal emulator, the one who "types those keys" is the terminal emulator, so it wouldn't be "burdened" by having to type a few more keys to have a clear and unambiguous encoding. > This is in no way singular: many terminal emulators convert > M-SOMETHING into ESC SOMETHING, at least as an option. That also somewhat sucks, but *much* less (and it was done at a time when you could argue that resource constraints made it important to have a "short and simple" approach rather than a "general, robust, and reliable" one).
