Even after reconstructing a valid URL from this, the server tells me
that the file does not exist.  Besides, a .dmg file is pretty useless
for somebody without a Mac (unless a more widely used file system
format is used in the image).

Styles in AUCTeX are keywords found during parsing, like options or
names of LaTeX packages.  In `TeX-output-view-style' you can check for
the presence of certain styles and invoke specific actions when found.

There is documentation?

We are not talking about Lisp here, but shell commands for invoking a
viewer.

Then I cannot help because I don't have Mac OS X.

Maybe the people making "plugins" for Emacs on Mac OS X (instead of
