PowerPoint tip 26

PowerPoint tip 26.

Remember the "B" key
If you press the "B" key while your PowerPoint or Keynote slide is
showing, the screen will go blank. This is useful if you need to digress
or move off the topic presented on the slide. By having the slide blank,
all the attention can now be placed back on you. When you are ready
to move on, just press the "B" key again and the image reappears.
