ABSTRACT:
An improved handheld electronic device and method provide an input apparatus having a number of input members, at least a portion of the input members being movable among an unactuated position, a first actuated position, and a second actuated position in order to provide input. The improved method of enabling input into the handheld electronic device includes detecting a first input from a first input member, responsive to the first input, performing a first navigational function, such as a scrolling operation, at a first speed, detecting a second input form the first input member and, responsive to the second input, performing the first navigational function at a second speed, the second speed being different (e.g., greater) than the first speed. The input apparatus may include a substantially sealable, resilient membrane with the input members being disposed on the resilient membrane in order to provide an improved, ruggedized input apparatus.
