Hi, 

1) could someone please substitute "last-command-char" with
"last-command-event" in cdlatex.el, as was suggested here [1], to be
able to insert carets and underscores in math-mode?

2) this:

\begin{align}\label{mylabel}
\left\{
\begin{array}{ll}
2+2 =& 4 \\
2+2 \neq & 4
\end{array}
\right.
\end{align}

gets exported badly, i.e. to this (notice how after \end{align}
everything repeats itself with escaping \):

\begin{align}\label{mylabel}
\left\{
\begin{array}{ll}
2+2 =& 4 \\
2+2 \neq & 4
\end{array}
\right.
\end{align}$\backslash$begin\{array\}\{ll\}
2+2 =\& 4 \\
2+2 $\backslash$neq \& 4
$\backslash$end\{array\}
$\backslash$right.
$\backslash$end\{align\}
\begin{array}{ll}
2+2 =& 4 \\
2+2 \neq & 4
\end{array}
\right.
\end{align}

it gets exported fine if \label{mylabel} is on its own line, instead of
right next to \begin{align}


cheers,
renato
