I never knew Powerpoint could do this, did you?
Pressing the "W" key in PowerPoint activates the "whiteout" feature, instantly turning the screen white. Similarly, pressing the "B" key activates the "blackout" feature, turning the screen black. These features effectively blank out the slides, eliminating distractions and drawing the audience's attention back to the presenter. This is beneficial for presenters because it allows them to regain control of the audience's focus. I never knew Powerpoint could do that. Every day is a school day I guess! I got this tip from Andy Bounds' Tuesday email. If you've not signed up for it, I suggest you do. It's fantastic and full of helpful hints and tips like the above.
