Unfortunately, although it always triggers under the same condition, it
doesn't trigger every time I'm in that condition.  In fact, I don't know
that I've every been able to trigger it more than twice in a day, even
when manually attempting to create the circumstances that might do so.
And some days I haven't been able to trigger it at all.
