Starting in Horta
To play this tour automatically, click in Google Earth on the subfolder "Descriptions, images and links" and press F10 to start it. It will then take You from Placemark to Placemark and point the virtual viewer to the right direction. To display annotations and images, klick on the caption of the placemark.
The speed can be set in Google Earth's "Tools" -> "Options" dialog, "Control" tab.
F11 toggles Google Earth in Fullscreen mode.
