Hyperlinks (Window > Interactive > Hyperlinks) let viewers click a link to jump to other locations in the same document, to websites, and more.
Animation effects (Window > Interactive > Animation) allow you to add different types of animation to content, like adding motion to an object on the page.
Buttons (Window > Interactive > Buttons and Forms) perform an action such as linking to a page or showing and hiding content.
Most interactivity cannot be previewed directly in the InDesign pages. Rather, it can be previewed in the EPUB Interactivity Preview panel (Window > Interactive > EPUB Interactivity Preview).
