Found a terrific cookbook for PmWiki that creates slides from a wiki page. Using a single wikipage, you delimit each slide with "!" then use regular wiki syntax. To activate, ?action=slideshow . I played a bit with it in the SandBox. Very easy to use the basic functionality. Issue I have is when content exceeds the size of the slide. I haven't yet figured out how to view that spillage...perhaps it cannot be viewed.

I could see creating a condition menu action item, "Slide Show," where it only appears when single "!" exists or some other flag.

Here's a sample...

insert ?action=slideshow to activate slideshow.
