To add a new one, click on the blank button at the bottom of the list, or to edit a button hold down Shift and click on it. The File Shuffler allows you to view any graphics files as icons instead of file names. The button at the bottom center of the dialog toggles the Shuffler on and off, if you want to see files in a more traditional list format. Under Options you see buttons for Plain and Special Event . Plain lets you add a solid color background, and Special Event lets you add a non-displayed page to the script.
Special events are useful for non-visual elements such as sounds.
Individual sounds can also be attached to a page, but special events are required for multiple sounds. To select a background, navigate to a folder containing suitable graphic files and double-click on the one you want. You may print , bookmark , email page or suggest ideas for this page about add background.
