Step-by-Step Instructions

Step 1: Enable Navigation Mode

  • Open the CommBox Whiteboard app from the home screen

  • Tap the Finger icon at the bottom of the screen until it shows a single pointing finger

  • This puts the whiteboard into navigation mode, allowing gestures like zooming and panning

💡 The single finger icon indicates that you are in movement mode, not drawing mode.

Step 2: Use Two-Finger Gestures to Zoom

  • Place both index fingers on the screen

  • Pinch your fingers together to zoom out

  • Spread your fingers apart to zoom in

💡 You can also pan around the whiteboard by using multiple fingers to drag the canvas.

Step 3: Move Drawings Around

  • While in navigation mode, use multiple fingers to grab and reposition drawings

  • This is useful when working on large diagrams or content that extends beyond the visible screen

Step 4: Return to Drawing Mode

  • Tap the Finger icon again until it shows dots on all fingers

  • This returns the screen to multi-touch drawing mode

💡 Switching back allows you to draw using multiple fingers or styluses as usual.
