The diff facility is very recent and should only work for text for the moment.
For the moment, I do not see any reasonable way for highlighting differences
in graphics (except highlighting the two versions as a whole).
Anyway, any ideas for improving the facility are welcome.

Hyperlinks are internal to TeXmacs. TeXmacs can open simple html pages,
and does not use a web browser by default.

Strange; it should be.

Even on simple examples?

Strange; we did not do anything for making links clickable.
Anyway, we use ghostscript for Postscript -> Pdf conversion.

Document -> Add package -> Example -> presentation
Document -> Magnification -> 1.4 / 1.7
Insert -> Fold -> ...
Insert -> Animation -> ...

No documentation available yet...

I don't understand what you mean by two paragraphs.
If you have two paragraphs with simple text, then you should be
able to join them by putting your cursor at the start of the second
paragraph and pressing backspace.

However, if one of the paragraphs contains block markup (e.g. one of them
is a theorem, or a list, etc...), then you cannot join them.

This depends a lot on the conversion tools installed on your system.
Anyway, this will probably be fixed automatically in upcoming Qt versions.

Ctrl-Tab.

Yes, you should use the .tm extension for saving TeXmacs files.
