title: How to fold all code between {{{ and }}} in vim
body: <p>I have a lot of code like this</p>
  
  <pre><code>#{{{
  code here
  #}}}
  
  #{{{
  more code here
  #}}}
  
  etc...
  </code></pre>
  
  <p>I want to fold all of them instead of going to each <code>#{{{</code> line and type <code>zfa{</code>.  </p>
  
  <p>I read the vim documentation and tried typing <code>set foldmethod={{{</code> but I got the error <code>E474: Invalid argument: foldmethod={{{</code> .  </p>
  
  <p>What do I press on my keyboard to tell vim to fold all code between <code>#{{{</code> and <code>#}}}</code>?  </p>
  
  <p>And what do I press to expand them all again?</p>
