## Description

When a user clicks a link or bookmark in a PDF, an action occurs, moving the reader to a new location.

An action can involve moving the reader to a new page in the file, for example.

Also, with a PDF Viewer a PDF file can have an Action that runs automatically when a user opens the file, or reaches a specific page.

Applications can support Actions in custom annotation types they add. Only GoTo and URI Actions are supported; you can only use an Action with the interface to move from one part of a file to another or open an external web page.
