Transitions are predefined dynamic settings that walk you and your audience through slides as you present.
After you’ve finished creating your presentation you can go to the ‘Transitions’ tab (which will display a board containing all your slides) and will allow you to customize their position. This will reflect how the presentation will look when you play it in front of your audience.

The right sidebar allows you to Search for a specific Journey. Besides choosing a specific journey you can also just arrange the way your slides will be played by choosing one of these predefined formats: Grid, Circle, Wave or Accordion.
The left sidebar contains the presentation overview and the search bar. This search allows you to perform a search through all your slides, responding to any word in any slide.
You can switch back to editing your presentation by clicking the Edit button in the main menu, or you can play your presentation.
