You can create buttons that perform an action when the document is exported to PDF format. For example, you can create a button that jumps to a different page of the PDF document or plays a movie clip.
After you create a button, you can do the following:
Make the buttons interactive.
Use the States panel to define the appearance the button takes in response to certain actions.
Set the tab order of buttons on a page.
When you create a button using the Button tool, you can drag the button area, or you can click to specify the height and width in a dialog box.
Click where you want the upper left corner of the button to appear, specify the width and height in the Button dialog box that appears, and then click OK.
You may want to add navigation buttons (such as Next Page or Previous Page) to a master page. In the exported PDF document, the button appears on all document pages to which the master is applied.
