Abstract

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.

Claims

1. An electronic device, adapted to provide at least a primary function and a secondary function, comprising:

a processor for providing computer functions in support of said primary and secondary functions;

a memory for providing a storage resource for said processor in support of said primary and secondary functions;

a key movable in first and second directions for activating the primary and secondary functions;

a sensor for detecting movement of the key in the first and second directions;

a timer for timing the period of time that expires between movement in the first direction and movement in the second direction; and

wherein said processor activates the secondary function in response to movement in the first direction, compares the expired period of time to a predetermined period of time and, if said expired period exceeds said predetermined period, maintains activation of the secondary function or if said expired period is less than said predetermined period, terminates said secondary function and activates said primary function.

2. The electronic device according to claim 1, wherein the first direction of movement is downward and the second movement is upward.

3. The electronic device according to claim 1 wherein said device provides a mobile communication function and said primary function is a call log/history function and said secondary function is a push-over-cellular function.

4. A mobile communication device for providing multiple modes of use, having a control processor adapted to provide at least a primary function and a secondary function, said mobile communication device comprising:

a key movable in first and second directions for activating said primary and secondary functions further comprising;

a sensor for detecting movement of the key in the first and second directions;

a timer for timing the period of time that expires between movement in the first direction and movement in the second direction; and

wherein said processor activates the secondary function in response to movement in the first direction, compares the expired period of time to a predetermined period of time and, if said expired period exceeds said predetermined period, maintains activation of the secondary function or if said expired period is less than said predetermined period, terminates said secondary function and activates said primary function.

5. The mobile communication device according to claim 4, wherein the first direction of movement is downward and the second direction of movement is upward.

6. The mobile communication device according to claim 4 wherein said primary function is a call log/history function and said secondary function is a push-over-cellular function.

7. A method for activating a primary and secondary function of a key in an electronic device having a control processor, said method comprising the steps of:

detecting movement of the key in a first direction;

activating the secondary function in response to the movement of the key in the first direction;

detecting movement of the key in a second direction;

maintaining the activation of the secondary function;

timing the period of time that expires between movement in the first and second directions; and

comparing the expired period of time to a predetermined period of time and, if said expired period is less than said predetermined period, terminating said secondary function and activating said primary function.

10. A computer program product for activating a primary and secondary function in an electronic device having a control processor for reading computer readable code, processor operatively associated with an electronic device, said computer program product comprising computer readable code for instructing said processor to cause said electronic device to:

detect movement of a key in a first direction;

activate the secondary function in response to the movement in the first direction;

detect movement of the key in a second direction;

maintain activation of the secondary function;

time the period of time that expires between movement in the first and second directions; and

compare the expired period of time to a predetermined period of time and, if the expired period is less than the predetermined period, terminate said secondary function and activate said primary function.

8. The method according to claim 11 wherein the first movement is downward and the second movement is upward.

9. The method according to claim 11 wherein said primary function is a call log/history function and said secondary function is a push-over-cellular function.

11. The computer program product according to claim 10 wherein the first movement is downward and the second movement is upward.

12. The a computer program product according to claim 10 wherein said primary function is a call log/history function and said secondary function is a push-over-cellular function.
