title: Google Earth/KML placemark balloon with a link that can play the tour it is contained within
body: <p>I am working with Google Earth (not plugin) and would like to find out if there is a way to Play a tour that is already loaded in the TOC from a placemark's balloon.  This placemark is actually part of the kmz that also contains the tour.  Is there a way to reference the Tour by Id and tell Google Earth to play it?  Thinking something like <code>&lt; a href=GE.Play(tourID) &gt;</code>.</p>
  
  <p>Any suggestion?</p>
