Abstract
Small electronic information storage and display devices such as paging devices with a limited number of control buttons allow user navigation of complex data structures by use of a single control button. Where a user has opportunity to branch within the data structure, the duration of control button actuation determines the selected branch. During the predetermined time interval, the user has visual indication of the item to be next displayed if the user maintains actuation of the control button. In this manner, a single control button supports navigation functions as might normally be established by two buttons such as a cursor right button and a cursor down button. Incorporating a second control button under the present invention supports a cursor left and a cursor up button. In this fashion, navigation of complex data structures occurs naturally and intuitively without requiring more than a limited number of control buttons.
