title: LaTeX: Unnumbered section in header of document
body: <p>I have a document where I want to place an unnumbered section in my header. I use the fancyhdr package, and for a numbered section, I would had done something like this:</p>
  
  <pre><code>\lhead{\leftmark}
  </code></pre>
  
  <p>But this don't work with unnumbered sections.
  I'm solving math-problems in my document, so I don't want part-sections and numbered sections</p>
  
  <p>Anyone, who knows, how this is done? </p>
