<<list-links filter:"[tag<currentTiddler>] +[sort[title]]">>
<<faceplant """Auuugh""">>
Yeah, the current documentation is flatout annoying - reviewing the filter
info, I can see that now, but the context had changed so many times by the
time I had gotten there I didn't even realize the significance of what I
was seeing. So would [tag<title>] work just as well at that point to pull
the tag from the Field?
Nope - evidently not. But aren't the fields supposed to be available as
variables here? So if <currentTiddler> works, shouldn't <title> do the same
thing?
