Well, yes, of course! ActiveEvent is the event that is currently handled
so if you hit Alt-P it's gonna be Alt-P ;-) What else would you expect?

Then, maybe you should explain where you need to use it. It appears to
me that if you are in some Morphic environment ActiveEvent will give you
exactly what you'd expect. As an example, you might try to select
then right-click to get the context menu, then press the shift key, and
release the mouse over the "printIt" entry. It should say "true" as a
result (at least it does so on my machine).
