There was a thread from last October about using growl for this same
sort of thing.  See http://www.zsh.org/mla/users/2011/msg00798.html
and surrounding conversation.

} Is it straightforward to somehow bind this to, say, control-return, or
} some other modified return key sequence?

There are two issues here:

(1) Your terminal emulator (I presume just the MacOS terminal app) must
send a recognizable different character or key sequence when you press
control-return -- I'm not in front of my Mac so can't test that now.

(2) It depends on what you want the binding to do.  For example, to
simply insert "tnot" in front of the current command and then run it:

tnot-widget() { BUFFER="tnot $BUFFER"; zle accept-line }
zle -N tnot-widget

and then bindkey for whatever character is sent by control-return, to
the tnot-widget.

I expect you're going to have more trouble with (1).
