One of the most powerful aspects of the InDesign workflow is the ability to develop your interactive experience independent of the publishing medium. This allows you to design your document in your existing workflow, then add the interactive elements that help you tell your story. On the back end, InDesign will create the necessary Flash or PDF programming, depending on which you choose during export. And of course, all of the print fidelity is still preserved, so your document can still go to press or be made available for on-demand printing.
When adding interactivity, InDesign will give you indications when certain interactive elements are only available for PDF or SWF. As we continue, we'll see evidence of this when setting up a table of contents or assigning actions to buttons.
