Abstract
Operations by an electronic device include randomly selecting an initial location among ordered keys for display of a selection indicia, and displaying on a display device the ordered keys containing symbols and the selection indicia at the initial location selected among the ordered keys. The operations further include moving the selection indicia from the initial location to a next location among the ordered keys responsive to a navigation signal from a user, and identifying one of the symbols as being selected by the user based on a present location of the selection indicia relative to one of the ordered keys containing the one of the symbols when a selection signal is received from the user. The one of the symbols is provided to an application as an input from the user.
