[Tex/LaTex] Problems with environments in TeXStudio

environmentstexstudio

This document

\documentclass{article}
\usepackage{amsthm}
\newtheorem{lemma}{Lemma}
\newcommand{\mycommand}{Here is the command}
\begin{document}
\begin{lemma}
Here is the lemma
\end{lemma}
\mycommand
\end{document}

is perfectly compiled but the problem is that TeXStudio says that \begin{lemma} \end{lemma} are unrecognized commands when I put the pointer on them and they have an horrible orange background (I know how to disable this but I don't want to because that feature is useful). The same happens when I define another environments. I often define a couple of theorem environments.

But the strange thing is that when I define a new command, TeXStudio does recognize it and the autocompletion feature works with both the new command and the new theorem environments (when I write \begin{lem} a box is shown with my new environment which is cool).

I'd like that TeXStudio recognize my environments.

Best Answer

It worked for me when I checked all the options in Options > Configure TexStudio > Completion > Use following completion files. I do not know which header file we need to use particularly in this case.
