iBooks Author: Add a Keynote file
You can add a Keynote slideshow to your book. To add a Keynote file created in Keynote 6.0 or later, you must have the latest version of Keynote installed on your Mac.
Note: Keynote files can contain media—such as images, movies, and audio—but don’t use a Keynote file just to add media to your book. Instead, use a Media widget or drag media directly to a book page.
Self-playing files and files with voiceover narration might not work as expected. In addition, some Keynote slideshow features (such as certain slide transitions) might not work as expected.
Add a Keynote file
Click the Widgets button in the toolbar and choose Keynote.
To add a file, do one of the following:
Drag a Keynote file to the Keynote widget.
In the Widget inspector, click Interaction, click Choose, and choose a Keynote file.
In the Interaction pane of the Widget inspector, do one of the following:
Set the slideshow to play within the book page when readers tap or click it: Click “Plays on page.”
Set the slideshow to play automatically when a reader views the book page: Select the “Plays automatically” checkbox.
Display the slideshow’s controls in iBooks: Select the “Show transport controls” checkbox.
Set the slideshow to play full-screen when readers tap or click its thumbnail image: Click “Plays full-screen.”
Continue to edit the widget: Select the thumbnail image, click Edit Keynote, make your changes, and click Done.
Change the thumbnail image: Drag a new image to the thumbnail.
You can also drag a Keynote file (.key) directly to the book page without adding a Keynote widget first.
Important: Images in a Keynote file shouldn’t be larger than 25 megapixels (5000 x 5000 pixels) or 50 MB.
You can’t interact with a Keynote slideshow in iBooks Author, but readers can interact with it in the completed book.
