title: How do I change the autocomplete key in Aptana
body: <p>I have looked through all of the keybindings under Preferences | General | Keys.</p>
  
  <p>I have also looked under Preferences | Aptana | Editors.</p>
  
  <p>All to no avail.</p>
  
  <p>Does anybody know how to change the autocomplete key from Enter to Tab or something like that?</p>
