I'll be damned, honestly, but I figured this out. Bob, you are correct, its all about multi-state objects. But also about how buttons trigger them. The real trick is creating layered files, and then within the multi-state layer, assigning a button to each active state. To do this you have to cycle through each of them in the layers stack and select the active file, then assign a button to it refering it back to an earlier state...It is actually very easy and simple. Reading through this last sentence though, it sounds complex, but its actually amazingly simple once you know how. When I get through this project, I'll post a "how to" do it.
I really wish Adobe would re-think this. It needs an interface outside of InDesign. As designers/creators, we're visual people. Apple's DVD Studio Pro's visual interface was a really simple way to grasp and arrange all these moving parts. I can see how Digital Publishing could easily be helped by a better, more intuitive way of working...
Kevin.
