Ah boo … that whole project has been scotched since Indesign doesn’t let you stack or customise animations. Even a simple, appear, pause, disappear is not available (although fly in, pause, fly out is!) … I could mess with the IDML snippets https://creativepro.com/animation-customization-via-idml.php … or am I just better off doing all this in Edge Animate or Flash? (Losing my ability to have multiple page sizes open in one document and also simply cut and paste my print elements?)

Indesign was so nearly a great place to make print ads into web ads. Not quite though.
