Here's an easy yet very useful tip for those who give presentations using PowerPoint slide shows from our OnSight Support Center.

When you want to stop for a break in your presentation without losing your place in the slide show, just press the lowercase B key or press the period (.).  This will cause the screen to go black, and if it is a self-running presentation, it will pause.  When you are ready to resume the show, press either key again and you will start right where you left off.
