Click in the toolbar and choose an option:
A percentage: The slide enlarges or reduces to the specific percentage.
Fit in Window: The slide adjusts to fill the window.

Click the green button in the top-left corner of the Keynote window.
Choose View > Enter Full Screen (from the menu bar at the top of your screen).
Move the pointer to the top of the screen if you need to use the Keynote menu or other menu bar controls.
To return to regular view, move the pointer to the top of the screen, then click the green button or choose View > Exit Full Screen.
