Dear list,
it is said, that C-M-a is bound to LaTeX-find-matching-begin. And it
should move to the \begin of the environment.
But that is not true. It does NOTHING.
In contrast to that: C-M-e works fine. Even it not possible to bind
C-M-a explicitly to LaTeX-find-matching-begin over .emacs.
LaTeX-find-matching-begin alone works rather fine.
But there sometimes is the message: ,,Can't find begin of
environment'', which is ridiculous.
It seems to be a rather severe bug in AUCTeX.
I use Emacs Version 26.3 with AUCTeX 13.1.
