Hi John,
this is a greet bit of info.
My first thought when the question was asked was "Hmm, what you need is
some sort of facility that could run a function when the cursor moves in
and out of a region". I then discounted the idea because of the amount
of supporting functionality which would need to be developed. The
pointer to cursor-sensor sounds like exactly the supporting
functionality I was thinking of. Should have guessed Emacs would have
something already!
Using org's font-lock mechanism as the 'trigger' is a great idea too.
I can see some great uses for this package as I have some pretty ugly
hacks which could be simplified if cursor-sensor works reliably.
thanks for the pointer.
Tim
