Consider a situation that you want to give a break to the audience or want to pause the slide show temporarily; you can turn the display to a "black screen".

To make a black screen, do the following:

1. On the slide that you want to take a break during the presentation, make the mouse pointer visible.

2. Move the mouse to the bottom-left button, click the third one, select Screen, and then Black Screen.

3. The display will change to a black screen.

4: To change from a black creen to present slide, press any key on keyboard or press the mouse button.
