Play a slideshow with multiple presenters in Keynote on iPhone
You can play a shared presentation online with multiple presenters. This is useful if you are presenting as a team while using a video conferencing app.
When you host a multipresenter slideshow, you control the presentation just as you do when you present alone. As host, you can start and end the slideshow, decide to play it in fullscreen or in a window, change slides, and edit the presenter notes at any time. If you aren’t the host, you have more limited control of the presentation—you can only advance or reverse the slideshow while sharing control with the host.
