Jeremy et al thanks! This almost worked as proposed, but I figured it out. I was having trouble getting the "#" into the field value.
Here is the working macro, currently implemented at DesignWriteStudio <http://designwritestudio.com/#Presentation%3A%20Text%2C%20Interactivity%2C%20Writing%20and%20Designing> (this is for a class I am teaching this semester at SUNY Polytechnic Institute). I had to do some odd dancing around in the defines to get the "#" to show up in the background-color field. Questions now: <1> on phone, the "prev" and "next" buttons are not properly displaying; too far over to the left <2> I'd like to set the slidenum field to be the same name as the "slidetag" -- so that a given tiddler can be used/ordered in multiple slideshows. That would require a transclusion of some sort that I haven't begun to figure out. <3> I'd hope to be able to color the slide in the same <list> as displaying the slides, but that may not be possible? As you can see, I run through the slides on a <list> twice: once to set the bg color, once to open into the story river. And I hope to bundle this as a plugin (soon). Thannks! //steve.
