While the Player preview gives you a good idea of how the topic will appear in the Player, some differences do exist. For example, when you preview in Player mode you do not see the entire Player interface such as the outline and other controls for searching, filtering by role, and so on. However, this option allows you to test a recorded topic to verify that all the frames and bubble text are correct.
See It! and Try It! modes both use simulated environments, while Do It! mode uses a live environment where you interact with the live application. In See It! mode, you watch while the simulation progresses. In Try It! mode, you click in the location indicated or type the specified text to advance to the next frame. In Know It? mode, you are required to complete a particular task and are scored on how well you complete the task.
Note: The appropriate Play Modes property must be set on the topic to preview it in a particular mode.
