To see which assets have been used in App Studio interactivity in the active layout, display the ** Digital Publishing pane of the Usage dialog box ( Utilities menu). Like the Pictures pane, the Digital Publishing pane lists the page number (a dagger symbol or PB indicates pasteboard) for each Digital Publishing asset in the layout. It also includes a Type column that indicates the asset type and a Source column that indicates whether the asset is a file or a folder. To view more information about the selected asset, expand the More Information area at the bottom.
