Hypertext and hypermedia have been object of great interest in the last few years. Two major areas of application are education and documentation. However hypertext, in spite of its interesting, and in some way unique features, is not problem free. As it is well known, disorientation is one of the most relevant problems the user can be faced with, and this gives raise to the "lost in the hyperspace" sensation. A possible way out can be the implementation of several interaction paradigms, in order that the user could find out, time to time, the right way to get the information necessary to continue the exploration of the hypertext.
