Jeremy et all,
I understand the use of nested delimiters. I expect the full answer I was
looking for relates to how the content is transcluded into the theme
as Tiddler styles
{{$:/themes/tiddlywiki/vanilla/sticky}}
Basically behind the reveal is conditional styling and a list widget.
Somehow the backticks are allowing literal text to be included in the theme
then interpreted as css or wiki text.
There is a code pattern here, that seems quite powerful, and I still don't
fully understand it.
Regards
Tony
