I'm not even sure I'm asking the right question:
I have two slideshow macros that invoke a slideshow, and then return to the
regular wiki. The slideshow macro changes theme, tags a few buttons so
they become visible in view template, and then launches the slideshow with
all tiddlers matching the specified tag. The slideshow is supposed to end
with a tiddler that has a "Return to Wiki" button, that invokes the
endslideshow macro, changing the theme back, untagging the buttons.
The trouble I am having is that I add the tag to the "end slide show"
tiddler, but of course it hasn't saved back to the wiki, so that my list
filter doesn't capture it, and I never get the end button.
Is there a command I can use that will save the wiki before I call the list
filter?
Thanks,
//steve.
(oh, and perhaps someone can explain the benefit/cost of using
action-setfield v. action-listops...)
