Thanks for the clarification. Do I get it right that the current Debian 12 (released this year) is shipping a 4 years old version of AUCTeX[1]? > I evaluated the code in scratch, or I think so: M+: and the code, no > line breaks. The minibuffer returned nil. Yes, this is then expected since you didn't install AUCTeX from ELPA. My suggestion presumed that. You have 2 choices now: • Activate AUCTeX the way you do it from your init file after 'emacs -Q' (I have no idea how one is supposed to do it on Debian) • You uninstall AUCTeX via apt and install it from ELPA as described here[2]. Then you can try the instruction I sent. > I opened a *.tex file with a TeX-master in local variables. However > the full AUCTeX bundle for LaTeX files was not available in the major > mode. Instead, the default TeX environment that is loaded with 'emacs > -Q filename.tex' was available. As if the eval code did not activate > AUCTeX actually. As a result C-c C-e did not launch an environment. Yes, this is then expected. What you did doesn't match your AUCTeX installation.
