While this is all complicated and helpful, I can see it's possible my
intent was missed.
I have 5 Tiddlers called Monday Tuesday Wednesday Thursday and Friday
Their contents are essentially a list of activities, with procedures/
times/etc for each of those days. Clearly I could use Outlook or
something, but the need for more contextual information for each
procedure, each step, is a need Tiddlywiki meets nicely.
I'd like to have the DefaultTiddlers contain a code of some kind that
will open the tiddler for the day of the week.
If it is Tuesday, I would like the Tuesday tiddler to be one of the
ones that opens. (I have other static tiddlers specified as well.)
Hope this helps figure out a simple and direct/single solution for me.
