Thanks, Dianne! I like to mess around with the timeline to take advantage of entrance and exit animations. What I did was create 2 copies of each flash card and stacked them in order to create two sets of flashcards on the timeline. I then staggered them, so that when the first flash card exited the timeline (fly out - to top), the second version of that flash card entered (fly in - from top). Since the animations were set to .25 seconds, it all happens so quickly it looks like the card just slides out of the deck and returns to the deck at the bottom of the stack. Hopefully that makes sense. Then I just set the timeline to pause after each exit/entrance animation and created hotspots for the user to resume the timeline. Then I created a trigger to jump to the same slide at the end of the timeline and set the slide to "reset to initial state" when revisiting. That way it just looks like the shuffling goes on and on.
