It’s best to structure your file as a Document which contains a Folder (with all your Overlays, Placemarks, etc) and a tour (not in the Folder).And later:
Note that Placemarks, description balloons, Polygons, Polylines, Models, Overlays (but no exploring ability for PhotoOverlays), and even NetworkLinks can all accessed by the tour.Good advice there, highlights added by me. I'd already thought that the tour allowed the turning on or off of any element (overlay, placemark, polygon) to be recorded, however, tinkering with the code and the KML example of updates (which is how tour does it) just didn't work for me.
For those of you who want to record a tour but not mess with the KML that drives it:
If the file is loaded already and the features are currently a mixture of on and off, check the top level box (should be for a Document or Folder) and turn everything on. Then start the Tour as described above, and the visibility states set in the feature KML and AnimatedUpdates will take care of everything.I'm not sure John didn't mean 'and turn everything OFF.' as in, turn everything off and then the tour will record you turning them on.
The creator of the GE5 tour has also surfaced as Googler Dan Barcay:
However, don’t take my word for it. This blog post is by the Googler who put an incredible effort into make the tour function a reality.If its possible for one person to give tumultuous applause, Dan gets it from me.
