If you wish to include useful information that should only be visible to you (the speaker) during your next PowerPoint presentation, here's how to do that.

When you decide to print PowerPoint slides, you can choose to print with or without Speaker Notes. Learn how to prints slides in PowerPoint.

To add notes to your PowerPoint, you'll need to have your presentation set to "Normal" view before accessing the "Notes" button for individual slides.

Note that typing in the note section won't be reflected at all on the slide. Add any other additional speaker notes as desired.
