    tdf#122582: Add ways to exit the slideshow in the iOS app
    
    Either going past the end, or pressing the 'q' key on a hardware
    keyboard will exit the slideshow by posting an 'EXITSLIDESHOW' message
    to the app. (The app will have to handle that, of course, will commit
    in a moment.)
