Knowls in PDF

[Rob Beezer]

Perhaps I'm late to the party. Just upgraded my PDF viewer, which is "evince"
on Linux. If you hover over a link in a PDF produced by PreTeXt, you get a
large preview of the target and its surroundings. Not a knowl per se (yes, that
subject line was link bait!), but it might save you from following a link, only
to be disappointed. And maybe sufficient when back in the index.

Screen shot is of Section 20 "Cross-Referencing" in the sample article. Only,
you don't see much of it, since I hovered on the hyperlink mid-page to Corollary
4.1, which is displayed in a large (half-page) pop-up/overlay.

Is this old news? Do other viewers do this? Besides its utility, it gives me
some confidence we have LaTeX/hyperref doing the right thing.

You *are* late to the party!

I think I posted about this about a year ago :-)

Obviously, I can't remember everything. ;-) And I'm only now getting to Ubuntu
22.04. Good thing I've switched to the LTS series only.
