Web pages: Make it easier for your end users to find out what's new with your product or documentation (perhaps there is a newer version of the PDF they are currently viewing). Using the ~httpBmk shortcut, you can easily also create a bookmark to a related web page -- in specific PDFs or as a standard item in all PDFs produced.
E-mail feedback: Make it easier for your end users to provide you with instant feedback via an e-mail message. A bookmark to an e-mail message can be displayed at all times (unlike a link present only on a specific page) and can be easily created with the ~MailtoBmk shortcut, in specific PDFs or as a standard feature in all PDFs being distilled. The e-mail message can contain pre-defined fields, including default document-specific subject line or message body. Spaces and other special characters are mapped automatically to the required syntax.
