To start a tour, open the Viewing Grid context menu and select Start Tour (shortcut Alt+T). To stop a Tour, press any key.
To set how long each Item is displayed 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 entire tabs - see "Showreel (Tour Cycle)".
