Chapter 3 Getting Started with Keynote 113
If you record a slideshow and then modify slides, the recording might be out of sync
with the slides. You can rerecord part or all of a recorded slideshow.
Step 3: Organize Your Slides
As described in “The Slide Organizer” on page 105, you can easily reorder slides by
dragging them in the slide organizer. There are other ways to organize your slides to
make it easier to work on your slideshow.
You can organize slides into groups by indenting them in the slide organizer.
To indent slides:
m Select the slide or slides you want to indent and press Tab.
∏ Tip: Select multiple slides by Shift-clicking (for a range of slides) or Command-clicking
(for noncontiguous slides).
You can create more indent levels by pressing Tab again. You can indent a slide only
one level deeper than the previous (“parent”) slide.
