How to find the matching environment command in tex mode?

Question

A latex environment looks like this:

\begin{envName}
body
\end{envName}

Is there a command to jump back-and-forth between matching \begin and \end commands? (One cannot simply use a regex search because environments can be nested)

Answer 1

LaTeX-find-matching-begin and LaTeX-find-matching-end functions do this.

   AUCTeX offers keyboard shortcuts for moving point to the beginning
and to the end of the current environment.
 -- Command: LaTeX-find-matching-begin
     ('C-M-a') Move point to the '\begin' of the current environment.
 -- Command: LaTeX-find-matching-end
     ('C-M-e') Move point to the '\end' of the current environment.
