A self-guided presentation needs routes through its content and a way back. A visitor might choose a service from a menu, read two detail slides and then choose another service. Design those routes before switching Keynote to Links Only playback.

Create a simple route list: menu to topic, topic to further detail, and each destination back to the menu. Use short, meaningful button labels so the audience can predict where a click leads.

Connect the slides deliberately

In Keynote on Mac, Control-click the shape or other intended navigation object, choose Add Link, then Slide. Choose the destination or specify its slide number. Use Go to Slide to verify that the link reaches the expected content.

Test one menu button and one return button before copying the design elsewhere. Reusing the appearance of a button does not establish that every copy points to the correct destination.

In the Document sidebar’s Document tab, choose Links Only from Presentation Type. Apple describes this mode as advancing slides or starting animations only when a viewer clicks a link. It also warns that every slide needs a link to avoid dead ends.

Rehearse routes as a visitor

Start playback at the intended menu and follow each branch. At every destination, verify the content and use the displayed return control. Include the last slide of each branch; that is an easy place to forget an exit.

Have another person try the deck without coaching. If they expect an ordinary click or arrow key to proceed, improve the visible instructions or navigation design. The success test is whether they can complete a route and choose another independently.

Repeat the route check after rearranging or removing slides. Keep a copy of the tested deck with its route list, especially if somebody else will maintain it.

This test concerns playback in Keynote. If the delivery will use a PDF, movie or another application, assess that separate format against the required interaction. Also treat access to the surrounding Mac separately: a presentation navigation mode is not a locked-down kiosk environment.
