Please look at Help->implementation->data format,
although this document is a bit out of date.
The main TeXmacs constructs are listed in src/Basic/Data/tree.gen.h.
<bullet> is just a symbol with a special meaning in certain fonts.
See Help->implementation->fonts, fonts/enc/*.enc and
progs/fonts/*.scm.

Unfortunately, no.

Yes, I definitely would like some tree-like representation of styles,
but this will take quite some time to implement.
Moreover, it is not yet clear which things should be seen
in code-like form and which things not.
We often would like the <bullet> to remain a real bullet for instance.
Also, we might want to have the math-mode menus displayed,
when we are in a logical position where math-mode is active.
Etc.

Well, the main documentation and tutorial are far from finished.
Any help on documentation is welcome.

No, I do not like the standard C++ template mechanism.
That is why I replaced it by the modular gencc system.
I do not intend to mix the two mechanisms.
