It depends entirely on your keyboard layout.  On a standard German
keyboard, for example, = is <shift>0, so C-= would mean pressing three
keys at the same time.  Also on the same keyboard, - and = are nowhere
near eachother.

Also, does C-= even exist on a typical tty layout?

Also[2], C-= is likely bound to many users' personal commands.

So I think I would be against using C-= for this command.
