Re: Ctrl-[ ?

[Francis Belliveau]

I think that a lot of you are missing the point that was made early on in the 
discussion.  This mapping of ASCII cntrol characters is a definition made by 
convention since the day of the Teletype machines.  It is how the ASCII 
character set was defined.

Some OS/driver implementations may hide it entirely from the application at the 
keyboard driver level.  When that it the case there would be no way for emacs 
to tell the difference between the C-[ and ESC keys because the OS-level 
keyboard driver sends the same code for both.  Think of these as synonyms.

If you are having trouble, the problem may be at that level or possibly in the 
"term-caps" definition in use.

Personally, I use C-i, C-[ as often as I use the backspace/delete and meta or 
escape keys.  It it just a matter of what is easier to use based on where my 
fingers, or what other keys I need to hit, are at the time.

Good Luck,
Fran
