That was fast! Thanks!
In fact, my first attempt was an event filter. But on Macintosh, I get no key event when I press cmd-period.
I expect the Objective C code will be required (groan). I wonder if anyone has already written something already that they would be willing to share. I get confused by having all those brackets in the wrong places :)
