Current navigation mechanisms for the World Wide Web promote a depth-first search for information on pages in hyperspace. This search strategy frequently results in the unintentional and often undesirable behavior of "web surfing"a user starts off in search of some information, but is sidetracked by tangential links. We propose a set of mechanisms based on breadth-first traversal that are better suited for directed searching. We have implemented our ideas as a scratchpad by augmenting an existing browser. Such a system makes web navigation both faster and easier.
