The real-time navigation of overlay slides in Adobe Captivate leverages interactive elements, advanced actions, and variables to create a dynamic and engaging learning experience.

Try It: Suppose you are creating a software tutorial. You can have a main slide showing the software interface and overlay slides providing step-by-step instructions or additional tips. A user can click a ‘Help’ button on the main slide to display an overlay with detailed instructions, which can be hidden again to continue with the tutorial.
