Abstract
A method for one button searching long lists is initiated by depressing a first search button to initiate a first mode scrolling search of a plurality of list members ordered in a list. Each list member is sequentially displayed on a small display, with the display typically being a handheld device capable of simultaneously displaying ten lines of alphanumeric characters. A second mode scrolling search is initiated after maintenance of the first search button in a depressed state and elapse of a first predetermined time interval of about one second. In the second mode scrolling search, a selected subset of list members, each having a same first letter, is ordered by their second letters for sequential display. A third mode scrolling search commences after maintenance of the first search button in a depressed state and elapse of another second, with selected subset of list members ordered by their first letter for sequentially display. Upon button release in either second or third mode, the search mode reverts to the next lower mode, with third mode going to second mode, and second mode going to first mode.
