I recently came across an interesting way to apply dynamic labels to complex syntax examples. Here are the explainers for CSS and HTML:
http://apps.workflower.fi/vocabs/css/en
It’s a very simple idea:
* On the left, there’s the text being explained, with conventional syntax highlighting
* On the right, there’s a list of terms
* Clicking on a term lights up the examples of that term
* Clicking on a block of text lights up the term
One of the things I like about it is that it works on touch devices because it doesn’t use :hover.
I’d be very interested to get something like this into the core documentation. Done with care it could help explain many of the subtleties that trip people when learning TiddlyWiki.
Best wishes
