title: What is Vim's feature name for this: # vim:sw=4:ts=4:et:
body: <p>Even after 20 years with Vim, I keep forgetting name for the Vim feature where the editor picks up config statements from a comment at the beginning (or I think end) of a file:</p>
  <pre><code># vim:sw=4:ts=4:et:
  </code></pre>
  <p>Thanks for a reminder!</p>
