NCSA Mosaic for the X Window System User's Guide
Should you decide to annotate a document, opening the Annotate Window
provides a large space to append your comments. The annotation, which
becomes a separate file, is added to the end of the original document
as a hyperlink under the heading ``Personal Annotations.''
Each time you open the original document, the hyperlink is displayed
under the Personal Annotations heading. An infinite number of annotations
can be made to a specific document. You can edit and delete annotations.
Each annotation entered separately through the Annotate Window becomes
a new annotation document.
