A secondary function, such as a push-over-cellular function, is mapped to the send key of a mobile communication device or other electronic device and is activated by the down stroke of the send key. The secondary function remains activated, providing the send key is held depressed for a set period of time. If the send key is released, before the expiration of the set period of time, the secondary function is terminated and the primary function, such as call log/history is activated.
