Architecture that facilitates the directing of viewer focus on selected content in the presentation document. Focus is visually represented using a focus viewport, which provides a bounded area in which the content of focus is enhanced for viewing, while content outside the viewport is impaired from being viewed. Selecting on a particular point or location in the document automatically activates the focus viewport and applies focus (e.g., enlarged viewing) to an area proximate the selection point. The content selected for focus can be tagged as a landmark section, which is then stored with other content tagged as landmark sections, some or all of which can then be run as frames in a movie strip for continuous review. |
