If you've ever given presentations, you know that keeping your audience's focus can be tough.
Part of the reason for that is because when you have a slide up there, the audience naturally wants to read what's up there. But ironically, while doing that, they are ignoring you, the presenter.
When giving a powerpoint presentation, sometimes, you’ll want to elaborate on something and get the audience’s full attention by blanking out the slide from the screen.
You can fold a piece of paper and put it over the projector, but here's a faster, more saavy way.
There are 2 ways:
1. Press the B key to black out the screen.
2. Press the W key to white out the screen.
Press the B or W key again to get your slide back on the screen. (it's not case-sensitive by the way)
