# Import of LaTex file

I am a new Lyx user and I would like to import LaTeX files into Lyx.
Apparently the importer cannot recognize enviroment like theorem, lemma,
remark, etc.
Consider this simple example:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\documentclass{article}%
\newtheorem{theorem}{Theorem}
\newtheorem{remark}[theorem]{Remark}
\begin{document}
\title{prova}
\author{prova}
\maketitle
\begin{abstract}
Bla bla bla bla
\end{abstract}
\section{section1}
Here is the theorem:
\begin{theorem}
\label{Thm1}This is Theorem 1.
\end{theorem}
\begin{remark}
This is the Remark.
\end{remark}
\end{document}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

If you import it into Lyx the \begin{theorem}, \end{theorem}
\begin{remark}, \end{remark} are not recognized by the importer and you
simple see it in red into the text.

Am I missing something? Is there any workaround to force Lyx to
recognize them?

Best regards
Luca
