The key phrase is "the same way you can bind any other key." Stefan's
suggestion does not comply with that.

I'm no one to chastise anyone. Sometimes I'm a bit too dry.

One thing that I'll like to know is why the hard restriction about
C-[/C-i exists at all. It is understandable that the default bindings
mimic what you get on the terminal, but forcing the user to jump through
hoops to rebind those keys helps no one. It looks as if a primitive
implementation detail remained like a living fossil to this days on the
C code base.

I suspect that it is related to how several Emacs hackers reacted to the
question posed by the OP: as if he were obviously wrong when requesting
that C-[ to do anything else. It seems that, on this topic, there are
two camps: those tty-minded and those gui-minded.
