Hello Yue, Posting your mail below back to the list where you have a better chance of getting the right explanation. I totally understand that many times copy directly latex chunk is a nice feature org-mode offers.
>From your example below, exporting the following script to latex would work ok in org-mode. #+BEGIN_SRC org #+options: toc:nil #+LATEX_HEADER: \usepackage{amsthm} #+LATEX_HEADER:\theoremstyle{theorem} #+LATEX_HEADER: \newtheorem{theorem}{Theorem}\usepackage{setspace} #+end_src * Theorem The longest word in this sentence is \emph{emphasized}. \begin{theorem} An emphasized a word looks \emph{distinguished}. \end{theorem} Yes, for my part I usually wrap into a source block, if I need native latex syntax #+BEGIN_SRC latex \emph{{n+1}-a} \textit{a{b}c} #+end_src I don't know if it is the case by design or if it is a bug.
