Keynote Action Pack contains free Automator actions for Keynote 3 (included in iWork `06) that supplement the actions that ship with Keynote 3.
The Keynote Action Pack action bundle will enable 2 Automator actions for Keynote. To install Keynote Action Pack, just place this bundle in the same folder as Keynote. There is no need to run anything, the actions should just automatically appear in Automator.
IMPORTANT: To avoid loading multiple occurences of the actions in Automator, only keep one copy of this bundle on your computer, do not duplicate it.
