Some popular uses for PDF are brochures, presentations, spreadsheets, contracts and forms - especially forms . You can create, fill in and submit electronic forms in Acrobat. You can fill in and print forms in Acrobat Reader . Many federal and local government Web sites have taken advantage of Acrobat by posting their entire archive of forms on line. Tools for enhancing PDF files with navigational features, such as thumbnails, bookmarks and links, make it easy to explore documents.
Thumbnails are minature previews of the pages in a document.
Interesting special effects that can be added include a particular action occuring when a bookmark, link or form field is selected, or when a page or form is viewed. For example, you can use links and bookmarks to jump to different locations in a document, but you can also use them to play movies and sound clips, execute commands from a menu or other actions. In Reader you can turn pages as in a traditional book, change the magnification of the page that you are viewing, and return easily to previous page views.
