title: sublime text swap line keyboard shortcuts
body: <p>I'm trying to use the swap line keyboard shortcuts in sublime text 2.</p>
  
  <p>I'm holding down command, ctrl, and up and down keys, but they're not doing anything.</p>
  
  <p>Using the edit menu item works though. I'm using a small mac keyboard. What could be the problem thanks.</p>
  
  <pre><code>[{
    "keys": ["ctrl+super+up"],
    "command": "swap_line_up"
  }, {
    "keys": ["ctrl+super+down"],
    "command": "swap_line_down"
  }
  
  ]
  </code></pre>
