title: RStudio and Sweave autocompletion for LaTeX commands?
body: <p>Is there a way to activate the autocomplete mode for LaTeX documents in RStudio? </p>
  
  <p>I know it's possible for JavaScript, HTML, CSS, Python and SQL, but what about LaTeX? </p>
  
  <pre><code>\documentclass{article}
  
  \begin{document}
  \SweaveOpts{concordance=TRUE}
  
  \sec 
  </code></pre>
  
  <p>I'd like here to press <kbd>tab</kbd> so that it autocompletes <code>\section{}</code></p>
  
  <pre><code>\end{document}
  </code></pre>
