Shortcut Command: Minimize all slide shows

Description:

This feature enables you to minimize all running slide shows. PowerPoint doesn't allow you to minimize a slide show so that you can look at the desktop. This feature allows you to do that. To restore the slide show back, click on the slide show's taskbar button.

For calling from macros:

Sub PPShortcuts_MinimizeAllSlideShows()
    Application.Run "PPShortcuts.ppa!MinimizeAllSlideShows"
End Sub
