Play a presentation on your computer in Keynote for iCloud
You can play your presentation on your computer whenever you want to preview it yourself, or when you’re ready to deliver it to an audience. By default, the presentation plays in your browser window, but you can also choose to play it full screen, depending on your needs.
Play in a window: Shows the slideshow in a window, which allows you to open the presenter display in another. This is useful when you don’t have a second display and want to see your presenter notes, or if you want to access your desktop or other apps without interrupting the presentation.
Play in full screen: Shows the slideshow in full screen on your computer while the presenter display, with your notes and controls, is hidden. This is useful when you want a more immersive experience and you don’t need to use, or don’t want others to see, the presenter display.
Note: If you want to show your presentation to others in full screen, while only you can see the presenter display, you need to connect a separate display to your computer. See Play a presentation on a separate display.
