1. Launch PowerPoint 2. Click 'Open Other Presentation' 3. Click the PowerPoint file you'd like to open 4. Click the Slide Show button near the bottom of the window 5. Hold Ctrl on your keyboard 6. Click and hold the left mouse button
Your mouse cursor will now turn into a glowing red dot, just as if you were holding and pointing a real laser pointer.
