Turn Your Powerpoint Slide into a Blackboard or a Whiteboard

This comes in handy when you are planning to give a PowerPoint presentation and want to draw or write on the background to explain something during your presentation.

Press B on your keyboard to instantly turn your screen black, creating a blackboard.

Press W on your keyboard to instantly turn your screen white, creating a whiteboard.

Now you can write on the blank background. To resume your presentation, press B or W again.

Alternatively, you can also right-click anywhere on the presentation, point to Screen, and select Black or White Screen.

Once you are done, right-click again to select Screen and then choose Unblack Screen or Unwhite Screen.

For tablets and other touchscreen devices, there is usually a blackout slide icon provided in the right-hand corner of the screen depending on the version of PowerPoint.
