Anyway, I agree that `M-TAB' is a bad choice for a key binding this
days, since many of the window systems out there steal the key, and
therefore an important thing like completion doesn't work logically out
of the box for many people.
Indeed, it won't work for most potential new users.
`C-TAB' is free, of course, but doesn't work on terminals, and I guess
the same is the case with all other modifier+TAB combinations. So I
don't know what we could do -- we could bind `C-TAB' for the GUI people,
for instance?
C-TAB is a good choice for a binding that won't conflict with the environment, as it's widely used by other programs for "switch tab", so it's unlikely that any window manager would steal it by default.
