Event Organizers and Speakers can share and switch slides during a Goldcast event.
Initiate the slide deck by selecting the Media tab on the Engagement Panel.

If only one slide deck is uploaded, it will auto-select so you don't have to navigate within the media tab to that specific slide deck. If you have multiple decks, you may change the deck by clicking the Change Deck link.

And selecting the deck you'd like to present.

Once you have the slides readily available in the media tab to your right, you can start presenting from slide 1 by clicking the Share button at the bottom of the Engagement Panel, or you can choose a slide to share by selecting its corresponding Share icon.

Use the arrows to navigate through slides while presenting.

To stop presenting the slides, click one of the Stop Sharing buttons at the bottom of the screen.

You can select different layouts when sharing slides on stage. Learn more details on the different layout options here.
