From within the sheets manager , click on to start the function Slideshow of sheets.
You only have to enter the time to wait between each sheet.
The slideshow will start from the currently active sheet, or from the first sheet if none is active.
During the slideshow you are free to perform changes to the 2D sheet.
But when the waiting time has elapsed, the 2D sheet is stored and the next sheet will be shown on screen without your intervention.
If you want to interrupt the slideshow, then click on the button in sheets manager.
