Understanding Interactive Presentations

Pro 6 Designs Gallery includes a subsection entitled Interactive Presentations, with a dozen themes provided. I can find no reference in the help file or in the title of any post on the forums. Can someone point out where I might find a description of their use -- or possibly provide a short explanation of how they should be used?

What I need is an easy way to build a slide show from Xara. In Xara 5, I constructed a multi-page document and then printed it as a PDF. Any PDF viewer could then be used to step through the pages. An Interactive Presentation sounds like a much better approach, but I don't want to start in a new direction without knowing if my use is basically in line with its capabilities and purpose.

Thanks in advance for any help.

Those templates are similar to web templates. You build a step-through presentation for displaying in a web browser.
These can be presented from a laptop connected to a projector for example.
They are not suitable for PDF export.
