Patent ID: 7532198

Claim:
A handheld electronic device comprising: a processor apparatus comprising a processor and a memory; an input apparatus cooperable with the processor apparatus; an output apparatus cooperable with the processor apparatus, the output apparatus including a display; and a housing; the processor apparatus being adapted to receive input from the input apparatus and to provide output to the display; the input apparatus including a plurality of first input members and a second input member, each first input member of at least a portion of the plurality of first input members having a plurality of linguistic elements assigned thereto, substantially each first input member of the at least a portion of the plurality of first input members being adapted to generate a first input upon being actuated; the second input member including a movable portion that is substantially continuously rotatable with respect to the housing about at least first axis and a second axis to provide input and, responsive to a rotation of the movable portion about at least one of the first axis and the second axis, the second input member being adapted to generate a number of second inputs, the rotation including a number of incremental rotations of the movable member a predetermined rotational distance, with substantially each incremental rotation corresponding with a second input of the number of second inputs; and the memory having stored therein a routine that is executable on the processor, responsive to a detection of a number of first inputs, the routine being adapted to output to the display a number of proposed linguistic elements and, responsive to a detection of successive second inputs, the routine being adapted to move an indicator, the indicator arranged to navigate throughout the proposed linguistic elements on to the display.
