This specification describes an information retrieval system such as a videotext or teletext system in which data is stored in conventional tree format, and the user has the usual capability to move vertically through the tree structure, but also has a novel capability to browse horizontally therethrough. This capability is achieved by providing each page of information with a browse link page pointer. The browse feature can be operated on an automatic repeat basis at a selected repetition rate, yet such automatic operation suspended at any time. In addition the user can return to normal vertical search procedure whenever desired.
