There are ways to trap events via an add-in, but this requires an add-in to
be installed on every machine that runs the slide show. An alternative is
to make sure that navigation to the last slide is via a button. You can
then have a line to go to that slide in a macro tied to that button as well
as whatever other code you want to run.
