Flyswat works in any document, including a Word file and emails. Just click on any of the words underlined in yellow and Flyswat will launch a window with links to related information. If you click a link in the Flyswat window, a new window isn't launched. So if you don't find what you need, you'll have to back up and click again on the word to return to the Flyswat window. Kind of a buzz kill.
Users add information to their virtual books by dragging and dropping it into the program.
They can also arrange the books into chapters, highlight pieces of text, and add sticky notes with personal comments. KeeBoo is only available for Windows. However, Mac users can employ their browsers to view KeeBooks that are emailed to them. It's like your own personal newspaper. You can view all of your information.
