title: What does <fd-35> mean on Vimgolf?
body: <p>I'm trying to improve my Vim skills through VimGolf (<a href="http://www.vimgolf.com/" rel="noreferrer">http://www.vimgolf.com/</a>) and I can't seem to figure out what the sequence <code>&lt;fd-35&gt;</code> means. <a href="http://www.vimgolf.com/challenges/4d1a1c36567bac34a9000002#4d1b5a82c58eaa2a8a000697" rel="noreferrer">Here's an example</a>.</p>
  
  <p>Thanks </p>
