About Saving Presentations
Graphics and chart data are saved within a Keynote presentations, 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 running Mac OS X v10.7 (Lion) or later, Keynote auto-saves your presentation
frequently in the background, so that you don’t have to worry about losing changes
made to your presentation 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.
