Not sure if I would consider this a feature or not, but here is something I noticed tonight. Try this:
Make 3 text frames, then link them. Fill with some arbitrary text so all have something in them. Now, in various combinations, set one or more as a PDF annotation (can just leave as a text type for this example). When you export to PDF, the annotation parts only show on mouseover/clicking, and the rest normally, so your complete text gets broken into hidden/unhidden parts. I'm trying to think about how I might make use this, perhaps in a presentation...interesting. Greg
