Here's an update on the status of clicking on a
link to the (PDF) User's Guide in the GUI help text. The precise
effect depends on the platform and the PDF viewer. There are two
questions:
1) Does the platform/viewer support opening the PDF at a
specified "named destination" at all?
2) If so, what happens on a second click on a GUI help-text
link, pointing to a different chapter: will the viewer
obligingly update the read position in the PDF file, or do you
only get one shot?
Linux:
evince: Yes on question 1, and Yes on the update in question 2.
xpdf: Yes on question 1; opens a new window in re. question 2.
okular: Supposed to be Yes on question 1, according to the docs;
I don't know about question 2. (I'm not in a position to test.)
other viewers: I'm not aware of any others that will cooperate.
Windows:
Adobe Acrobat/Acrobat Reader: Yes on 1, and also Yes on updating
the viewing position now that I've added some DDE code (in git
and snapshots).
other viewers: I'm not aware of any others that will cooperate.
If this comment on other viewers intends to be also a inquiry,
checking with the PDF Reader that's embedded in Windows package, it
seems only capable of open the Guide (not the chapter). But with
Acrobat, all works fine with yesterday's snapshot and I think it's
all most Windows users really need. Great!
Mac:
Nothing doing, so far as I can see. I can't get Adobe
products to do anything useful, nor the native Apple
Preview.app. I can't find any relevant documentation. I did try
a few experiments aimed at Acrobat Reader DC,
but to no effect.
