This is for the PowerPoint users/presenters.
If you are running the PowerPoint presentation (Pressing F5 will always run the show), and you get to a point where you need the full focus of the audience, then you press B or W and it will Black out or White out your screen. Try it out!
Shortcuts:
F5 – Runs the Show
B – Blacks the screen out
W – Whites the screen out
My Dad shared this shortcut with me! He loves teaching me new stuff!!!
