Presentation Tools

When your presentation is live on the stage, you have access to the following tools to help manage the experience smoothly:

Quickly review your slides during the session without showing them to attendees.

  • Ideal for planning upcoming slides.
  • Enables presenters to jump between slides seamlessly.

2. Manage Presenters

Control who can navigate or interact with the slides during the webinar.

  • Assign or revoke slide control permissions for speakers.
  • Only users with permission can move slides forward or backward. 

3. Back and Forward Arrows

Easily navigate through the presentation using arrow controls.

  • Use ← to move to the previous slide.
  • Use → to move to the next slide.
  • Visible only to users with slide control permissions.

4. Full Screen

View the presentation in full-screen mode for a focused experience.

Configuring Slide Permissions

Understanding how presentation permissions work for guest speakers and file owners:

  • Guest Speakers:
    If a guest speaker joins after the session has started, they won’t automatically have permission to control the presentation. The host or file owner must manually grant them access.
     
  • File Owners (Speakers):
    If a speaker who uploaded the presentation joins after the session has started, they will automatically receive control of the slides, since they are the file owner.

You can modify who has control over the slides at any time during the session.

How to Change Permissions:

  • Click on the “Presenter Control” icon:

Available in the side menu (marked as A)

Also accessible directly on the stage (marked as B)

  • This will open the Presenter Control Popup.
  • In the popup, select the speakers you want to grant slide control access to

Once selected, the chosen speakers will be able to navigate through the slides during the session.

While sharing the slide, you can also select the permission of the control.
