PowerPoint Black and White

When making a presentation using Microsoft PowerPoint, there will be moments when you like to have the audience's full attention. However, leaving a slide projected while you talk can be a distraction. To quickly stop the projection of a slide either press B on the keyboard to turn the display black, or tap W to have Powerpoint project a pure white screen. When you're finished talking, simply repeat the keypress to revert the display back to the slideshow.
