I didn't realize that. Not nice.

I was tricked into thinking this, because I did C-h m in a dtx buffer, and then clicked on doctex-mode.el there (docTeX/FPS mode defined in ‘tex-mode.el’) and came in the standard TeX mode to my surprise. I just overlooked the :override advice: ‘TeX-doctex-mode’.

But maybe you can answer another question.
I want newline in a dtx buffer to automatically insert the % at the beginning of the line. You have to set TeX-newline-function to an appropriate value. I thought LaTeX-newline would be a good value, but that is not interactive. So I ended up with:
(setq TeX-newline-function #'(lambda () (interactive) (LaTeX-newline)))

Is there a better way? Or would I rather request LaTeX-newline to be made interactive?

With kind regards,
