Exactly, since dead-key+space enters the compose character
itself. Hitting ^ does trigger the "buffer read-only" warning though,
since the code tries to insert the overlay at that point.

Yes, while playing around with the code I implemented that (it still did
"swallow" the next keypress though, so it's not really usable), and I
wondered if this behaviour could be confusing to some people, since they
might expect that the "^" _character_ and not the keypress itself
triggers a command? (I usually use the US layout, so I don't have a
strong opinion on that anyway :-) ).

OK, thanks again!
