1. A method for producing an audible incremental sound that emanates from a speaker of a handheld electronic device, the method comprising: sensing non-accelerating movement actuation of a navigation tool of the handheld electronic device; producing one or more signals in response to sensed non-accelerating movement actuation of the navigation tool; controlling motion of a cursor on a display in response to the one or more signals; generating audible incremental sound from a speaker included in the handheld electronic device in response to the one or more signals, the audible incremental sound indicating accelerated cursor movement on the display, the audible incremental sound being generated independent of a location of the cursor; producing accelerated cursor movement on the display based on interpreting the one or more signals; and increasing a rate of repetition of the generation of the audible incremental sound to match movement of the cursor on the display in response to the sensed non-accelerating movement actuation of the navigation tool, where the rate of repetition is increased independent of the location of the cursor.
