Special blocks in LaTeX export (The Org Manual)

13.10.10 Special blocks in LaTeX export

For other special blocks in the Org file, the LaTeX export back-end makes a special environment of the same name. The back-end also takes ‘:options’, if any, and appends as-is to that environment’s opening string. For example:

#+BEGIN_abstract
  We demonstrate how to solve the Syracuse problem.
#+END_abstract

#+ATTR_LATEX: :options [Proof of important theorem]
#+BEGIN_proof
  ...
  Therefore, any even number greater than 2 is the sum of two primes.
#+END_proof

exports to

\begin{abstract}
  We demonstrate how to solve the Syracuse problem.
\end{abstract}

\begin{proof}[Proof of important theorem]
  ...
  Therefore, any even number greater than 2 is the sum of two primes.
\end{proof}

If you need to insert a specific caption command, use ‘:caption’ attribute. It overrides standard ‘CAPTION’ value, if any. For example:

#+ATTR_LATEX: :caption \MyCaption{HeadingA}
#+BEGIN_proof
  ...
#+END_proof
