Apple Keynote '09 - Manual (Page 33)

Chapter 2 Creating, Opening, and Saving a Keynote Presentation 33
You can generally save Keynote presentations only to computers and servers that use
Mac OS X. Keynote is not compatible with Mac OS 9 computers or Windows servers
running Services for Macintosh.
If you plan to share the presentation with others who don’t have Keynote installed
on their computers, you can export it for use in another application. To learn about
exporting your presentation in other file formats (including QuickTime, PowerPoint,
and PDF), see “Sharing a Presentation Across Platforms” on page 217.
Saving a Copy of a Presentation
If you want to duplicate your open presentation, you can save it using a different name
or location.
To save a copy of a presentation in Mac OS X v10.7 (Lion) or later:
1 Choose File > Duplicate.
An untitled copy of the presentation is created. Both copies remain open on your
desktop for you to view or edit.
2 Close the window of the untitled copy, type the presentation's name, and then choose
a location from the pop-up menu.
3 Click Save.
To save a copy of a presentation in Mac OS X v10.6.x (Snow Leopard) or earlier:
Choose File > Save As and specify a new name or location.

When the presentation is copied in this way, the original presentation is closed; the
presentation that remains open on your desktop is the new copy you created. To work
with the original version, choose File > Open Recent and choose the previous version
from the submenu.
You can also automate creating a backup of the presentation every time you
save, retaining the name and location of the original, but with the words “Backup
of” preceding the filename. See “Automatically Saving a Backup Version of a
Presentation” on page 33.
Automatically Saving a Backup Version of a Presentation
Each time you save a presentation, you can automatically retain a copy of the last
saved version. That way, if you change your mind about edits you made, you can go
back to (revert to) the backup version of the presentation.
