Hi, Jonas
if you enter in the AUCTeX buffer (C-c') and than you use the AUCTeX C-c C-e, you can choose the environment you need in the emacs minibuffer such as in LaTeX.

the only remaining problem is that the AUCTeX mode tries to be smart
about what environments it allows to insert. f.ex. inserting

#+begin_src latex

#+end_src

then C-', brings one to a source buffer with AUCTeX-mode enabled.

But a C-c C-e to insert an environment doesn't want to complete on
itemize or figure, but instead only allows to choose document (Which
would be perfectly sane under the assumption that the buffer contains
the whole tex-document).

Does anybody know how to deactivate this "feature" of AUCTeX? Perhaps
setting TeX-master-file to something special?

Thanks,
Jonas
