Thanks Ross.  I've been fiddling with that a bit (a very little bit,
being distracted by other, higher priority tasks), but haven't figured
out the right incantation yet.  I may have to (gasp) look at the
source code :-)  Or maybe the monkey in me will eventually press the
right combination of keys to make it work.  The lazy programmer in me
was hoping somebody would say "Oh yeah, I do that all the time.  I
just blah blah blah".
