Rehearse your presentation
When you play a presentation in the Rehearse Slideshow mode, you can see the current slide, your presenter notes, and a clock on the screen of your Mac. This view makes it easy to rehearse a presentation.
You can add items, such as a timer and the next slide, and you can modify their layout.
Rehearse with the presenter display
Open the presentation, then choose Play > Rehearse Slideshow (from the Play menu at the top of your screen).
The presenter display appears.
To advance through the presentation, do any of the following:
Go to the next slide or build: Press the Right Arrow key.
Go back a slide or reset the builds on the slide: Press the Left Arrow key.
Jump to a different slide: Press any number to make the slide navigator appear, enter the slide number, then press Return.
To stop rehearsing, press Esc.
You can click to customize the presenter display with different items and a different layout.
