If you prefer to share voting instructions with your audience ahead of time, you can share the QR code or voting link. The QR code and voting link are unique to your presentation and will remain the same regardless of the voting code.
How to share the QR code
In the edit view of your presentation, open the "Share" menu
Select the "Participation" tab
Click the "Download QR" button to download the QR code

To show the QR code to a live audience:
Click "Present" in the top right corner of the Edit View
Open the Presentation Menu
Choose "Show voting instructions"
Pro tip: You can also use the shortcut key 'i' when presenting, to show or hide the QR code.
To get back to the presentation, simply press the "esc" key on your keyboard.
