Click the Present button in the top toolbar. Your window will change to present mode.

Use the arrows at the bottom of the presentation to navigate along the path. You can also use your left and right keyboard arrows. You can also freely navigate through your presentation by clicking directly on a topic or subtopic.

You can enter or exit full screen by clicking the icon in the lower right corner of the window.

You can use your mouse’s scroll wheel or the scroll movement on your touchpad to zoom in and out. This means you can move from subtopics to the main topic to the overview with the flip of a finger.
