Ah, now I get what you are saying. Well, (La)TeX has no real notion of
a sexp, so `forward-sexp' and `backward-sexp' basically move over words
and symbols (TeX macros), or from one (, [, or { to the respective
closing paren/bracket.
But you can give Magnar's awesome expand-region a try.
https://github.com/magnars/expand-region.el
That has support for expanding the current region also in LaTeX specific
ways. E.g. with
\begin{enumerate}
\item foo
\item _b_ar
\end{enumerate}
where the _b_ means point is on the b in bar, calling er/expand-region
results in
\begin{enumerate}
\item foo
\item _bar_
\end{enumerate}
where the complete _bar_ is marked, another call gives
\begin{enumerate}
\item foo
_\item bar_
\end{enumerate}
where the complete \item ... is marked, another two calls mark all
items, and a final call markes the complete environment.
I think that's exactly what you want, right? And expand-region.el can
do this magic not only for latex but also for lisp, ruby, python, xml,
javascript, CSS, and what not.
Bye,
