Add presenter notes in Keynote for iCloud
You can add notes to any slide to help you present. When you play your presentation, you can view your presenter notes in the presenter display.
Add presenter notes to a slide
Click the View button in the toolbar, then choose Show Presenter Notes.
Type your notes in the white area below the slide.
In the slide navigator, the thumbnails for slides with presenter notes have a small lined square in the top-right corner.
To format your notes, select the presenter note text, then use the controls in the Format sidebar on the right.
You can also add and edit presenter notes in the presenter display. See Customize the presenter display.
Hide presenter notes
If you want a little more room to work on the slide canvas, you can hide presenter notes while working on your presentation.
Click the View button in the toolbar, then choose Hide Presenter Notes.
