Graphics and chart data are saved within a Keynote presentation, so they display correctly if the presentation is opened on another computer. Fonts, however, are not included as part of the presentation. If you transfer a Keynote presentation to another computer, make sure the fonts used in the presentation have been installed in the Fonts folder of that computer.
By default, audio and movie files are saved with Keynote presentations, but you can change this setting. If you don’t save media files with the presentation, you need to transfer them separately to view them within the presentation on another computer.
If you’re using OS X Lion (v10.7) or later, Keynote automatically saves your presentation as you work, so you don’t have to worry about losing changes if the application closes unexpectedly. You can also save the presentation manually, creating an archive of older versions, which can be recovered at any time.
