title: Vim sync syntax from beginning of file on command
body: <p>When working with HTML with embedded Javascript, the syntax highlighting often gets out of sync.  If I tell vim to always sync from the beginning of the file, navigation is too slow.  I was wondering if there is a way to tell vim <em>on command</em> to sync from the beginning of the file.  As in, "ok this is the code I'm working on, make it look right".</p>
  
  <p>Thanks</p>
