  Click on the Occlude button to bring up a dialog box,
  allowing you to specify occlude options for the
  transaction.

  This temporarily overrides any default occlusion you may
  have set in the Options menu.  After the current
  transaction, CMS uses whatever defaults you have set in
  the Options menu.
