A tray-based utility that lets you create bookmarks for documents you're looking at in the Adobe Acrobat Reader. Just highlight some text, double-click on the Reader's vertical scroll bar to bring up a menu, and select 'New Bookmark'. The menu also lists all bookmarks you've added.A bookmark not only saves the text position, but records the zoom level and page layout as well. This makes it especially convenient for working with documents that contain circuit diagrams, schemes, and datasheets. Bookmark Keeper also supports the Acrobat plug-in for Microsoft's and Netscape's Web browsers.
