The Presentation mode represents another way to view documents in Okular. It can be enabled in View → Presentation. It shows the document on a page per page basis. The pages are shown with zoom to page, that means all the page is visible.

To navigate between pages you may use the left mouse button (next page) and the right mouse button (previous page), the mouse wheel, the arrow icons or the line edit in the top bar, or the keys specified in the Navigating section.

Use Play/Pause button in the top bar to start playing presentation or pause it, correspondingly.

You can exit presentation mode at any time by pressing the Esc key or clicking the Quit icon in the top bar.
