title: Sublime Text 2 sidebar context: Vim-like key bindings for sidebar navigation
body: <p>Does anyone know the "context" for the Sublime Text 2 side bar, or have any idea how to find the context?  </p>
  
  <p>I use Sublime Text 2 in Vintage mode, and along with several custom key bindings (and VintageEx) rarely have to leave the home row.  Re-binding 'j', 'k', and the likes without specifying a context carries over to Insert mode in the edit window(s) so that there is movement rather than typing j or k.  To be more concrete, any thoughts on what should replace '???' in this mapping:</p>
  
  <pre><code>{ "keys": ["j"], "command": "move", "args": {"by": "lines", "forward": true} , "context": [{"key": "???"}] }
  </code></pre>
  
  <p>to use 'j' in place of the down arrow in the sidebar?</p>
  
  <p>Many thanks!</p>
