InDesign lets you create hyperlinks and anchors within your documents to Web addresses, pages, and text in your InDesign document, and to pages and text in other InDesign documents that are then clickable from a PDF file created from your InDesign file.
You can also create buttons that have associated actions such as opening a movie file, closing a page, changing the zoom level, or moving to a new page when exported to PDF format. InDesign also lets you import movie and sound files that likewise play in exported PDF files.
