Currently, you can select "a" as a region, then on the gud-print tool bar icon
to print the value of a (in the GUD buffer), select "b" to see value of b,
select "b->c" to see value of b->c and select "b->c->d" to see value of

But you seem to be saying bind a mouse event to gud-print and change how it
parses expressions.  Mouse-1 is needed for normal use of the source buffer,
like editing.

Expressions aren't always bracketed.  Parsing an expression can be quite
complex as gud-find-c-expr shows.  By selecting the user can ensure he
gets exactly what he wants.

You can currently toggle them from the menu bar.  With 80 columns and starting
with "--fullname" there's no room left on my tool bar.

I agree that tooltip-identifier-from-point doesn't always do what you want
but it's safe.  Gud-print will call procedures e.g abort (), which you
wouldn't want to happen if the mouse just lingered too long over it.

tooltip-identifier-from-point could be enhanced if you specified all the
differences between existing behaviour and desired behaviour.
