When you are in the middle of a PowerPoint or Keynote presentation, you can make the screen go black at any time by pressing the letter “B” (as in “Black”). You can also make the screen go black with most remote controls. There are a few instances when I recommend using this feature.
First, if you have a long presentation—say, for example, a full day workshop—turning the screen black will give your audience a rest from the screen. And, it will allow them to refocus on the most important part of the presentation: You.
Second, and this is similar to the first point, if you are going to spend an extended period of time discussing something that you have just shown, and if your audience does not need the information on the screen as a reference, going to black will allow your listeners to focus on the discussion instead of letting their eyes wander back to the screen as is only human nature.
Third, if you have a Question and Answer session, I recommend going to black. As I have previously written, you do not need a slide that says “Questions?”. Just invite the audience to ask any questions.
Fourth, unless you wish to end with a powerful slide (an image, a call to action, a summary of your key points, your contact details, etc.) go to black and end with the focus on you. Whatever you do, please don’t exit the presentation and then fiddle with the programme. It is distracting and unnecessary. And, if you are using a PC, unless you turn the beamer off, the Microsoft flag will soon be waving and jumping about behind you, mesmerizing your audience and drawing attention away from you.
Some technical points to keep in mind:
1. Many people prefer to insert black slides at strategic points in their slide presentations. The advantage is that when you advance the slide from black, the next slide appears. (When you black out the screen with your remote or the keyboard, you return to the same slide.) However, having black slides in the slide deck means that you have to remember where they are and that you must click through them.
2. You can only go to black by pressing “B” while the PowerPoint is in presentation mode. If you hit escape and go into edit mode where everyone can see thumbnails of your slides—something you should not do—this function will not work.
3. If the operating system of the computer is in another language, the “B” key might not work. For example, if the operating system is in French, “B” will make the screen go white because “B” is for “blanc“, which means “white” in French. “N” (for “noir“) will make the screen go black.
4. If you go to black, you can come back any time by hitting any key.
5. For those of you who prefer white, you can have a whiteout by pressing . . . yes, you guessed it . . . “W”. I don’t like white because I find the brightness too harsh. I would only recommend going to white if you are going to do hand shadows as part of the presentation, and then, only if you are as good as Raymond Crowe.
