To start a tour, open the Viewing Grid context menu and select Start Tour (Alt+T). To stop a tour, press any key.
To set item display length in a Tour
1. Open Main Menu and select Local Settings.
2. In the Look and Feel tab, use Tour Cycle to specify the desired duration (in seconds).
It is also possible to cycle through layout tabs – see "Showreel (Tour Cycle)".
