title: Using Python mechanize on specific form with javascript
body: <p>I'm trying to use the Python mechanize module to retrieve data through this form: <a href="http://archive.stsci.edu/kepler/data_search/search.php?form=fuf" rel="nofollow">http://archive.stsci.edu/kepler/data_search/search.php?form=fuf</a></p>
  
  <p>The thing I'm having trouble with is "Output Columns" area in the lower left, which uses javascript to specify the output format. I'd like to be able to select a specific list of items, which would normally be selected with the surrounding javascript buttons.</p>
  
  <p>I'm new to mechanize and haven't looked at javascript in ages. I've been looking through the responsible javascript but am unsure of what to do. Any tips? </p>
  
  <p>More specifically: Is there a way to use mechanize to modify the elements in a list?</p>
