title: how can I edit my current sublime text 2 theme?
body: <p>I would like to update my current SB2 theme Sunburst so that the current line highlight is a little brighter but I'm not sure how to do this. I know the following code has to be added but I don't know how to access the theme files:</p>
  
  <pre><code>&lt;key&gt;lineHighlight&lt;/key&gt;
  &lt;string&gt;#hexcolor&lt;/string&gt;
  </code></pre>
  
  <p>Can anyone advise on how this can be achieved?</p>
