The Replayer allows you to play back any hands in PT3.
You can either double click an individual hand in a report like the Known Starting Hands Detail report then click the 'Replay Hand' button; or you can click the little Play icon to the right of the report to replay all hands in order.
The replayer itself allows you to step through the actions within a hand or between hands. The controls should be pretty self explanatory - if there's anything you can't work out please ask.
(There will be a tutorial at some point, but I can't say when)
