To create an unattended presentation:
- Ensure all animation effects are set to appear automatically. Use the Timing Options command on the effect's action menu and configure the effect to happen automatically after a prescribed delay.
- Ensure that all slides are set to advance automatically. You can configure automatic advance in the Slide Transition task pane, or rehearse the presentation once to capture timing.
- Choose Slide Show → Set Up Show and select Loop continuously until 'Esc'. Also ensure the Advance option is set to Use timings, if present.
