Abstract

In an electronic device having a keyboard (120) and a display (116), a processing system (106) displays on the display a message entered through the keyboard and selects a supplemental mode, in response to entry of a first predetermined key sequence by a user. The supplemental mode is selected in accordance with the first predetermined key sequence, from at least one of a group of supplemental modes included in the electronic device. The group of supplemental modes comprise an acronym mode (200), a supplemental scrolling keyboard mode (300), a predictive character pairing mode (301), a predictive menuing mode (400), and a bi-directional delete mode (500). The electronic device operates in accordance with the supplemental mode until an occurrence of at least one of (a) the user entering a second predetermined key sequence and (b) the supplemental mode executing to completion.

Claims

1. A method in an electronic device having a keyboard and a display, the method for supplementing the keyboard and for helping a user to operate the electronic device, the method comprising the steps of:

displaying on the display a message entered through the keyboard;

selecting a supplemental mode, in response to entry of a first predetermined key sequence by the user, the supplemental mode selected in accordance with the first predetermined key sequence, from at least one of a group of supplemental modes included in the electronic device, comprising;

an acronym mode;

a supplemental scrolling keyboard mode;

a predictive character pairing mode;

a predictive menuing mode; and

a bi-directional delete mode; and

operating in accordance with the supplemental mode until an occurrence of at least one of (a) the user entering a second predetermined key sequence and (b) the supplemental mode executing to completion.

2. The method of claim 1, wherein the selecting step comprises the step of selecting the supplemental mode from at least two of the group of supplemental modes.

3. The method of claim 1, wherein the selecting step comprises the step of selecting the supplemental mode from at least three of the group of supplemental modes.

4. The method of claim 1, wherein the selecting step comprises the step of selecting the supplemental mode from at least four of the group of supplemental modes.

5. The method of claim 1, wherein the selecting step comprises the step of selecting the supplemental mode from at least five of the group of supplemental modes.

6. The method of claim 1, wherein the method further comprises the step of

sending the message from the electronic device to a receiver, in response to keyboard entries made by the user in the predictive menuing mode.

7. An electronic device for supplementing a keyboard and for helping a user to operate the electronic device, comprising:

a processing system for controlling the electronic device;

the keyboard coupled to the processing system for entering a message and storing the message in the processing system;

a display coupled to the processing system for displaying the message;

wherein the processing system is programmed to select a supplemental mode, in response to entry of a first predetermined key sequence by the user, the supplemental mode selected in accordance with the first predetermined key sequence, from at least one of a group of supplemental modes included in the electronic device, comprising;

an acronym mode;

a supplemental scrolling keyboard mode;

a predictive character pairing mode;

a predictive menuing mode; and

a bi-directional delete mode; and

wherein the processing system is further programmed to operate in accordance with the supplemental mode until an occurrence of at least one of (a) the user entering a second predetermined key sequence and (b) the supplemental mode executing to completion.

8. The electronic device of claim 7, wherein the processing system is further programmed to select the supplemental mode from at least two of the group of supplemental modes.

9. The electronic device of claim 7, wherein the processing system is further programmed to select the supplemental mode from at least three of the group of supplemental modes.

10. The electronic device of claim 7, wherein the processing system is further programmed to select the supplemental mode from at least four of the group of supplemental modes.

11. The electronic device of claim 7, wherein the processing system is further programmed to select the supplemental mode from at least five of the group of supplemental modes.

12. The electronic device of claim 7, further comprising

a transmitter coupled to the processing system for sending the message from the electronic device to a receiver, in response to keyboard entries made by the user in the predictive menuing mode.

13. A portable subscriber unit for supplementing a keyboard and for helping a subscriber to operate the portable subscriber unit, comprising:

a receiver for receiving information;

a processing system coupled to the receiver for processing the information and for controlling the portable subscriber unit;

the keyboard coupled to the processing system for entering a message and storing the message in the processing system;

a display coupled to the processing system for displaying the message; and

a transmitter coupled to the processing system for transmitting the message,

wherein the processing system is programmed to select a supplemental mode, in response to entry of a first predetermined key sequence by the subscriber, the supplemental mode selected in accordance with the first predetermined key sequence, from at least one of a group of supplemental modes included in the portable subscriber unit, comprising;

an acronym mode;

a supplemental scrolling keyboard mode;

a predictive character pairing mode;

a predictive menuing mode; and

a bi-directional delete mode; and

wherein the processing system is further programmed to operate in accordance with the supplemental mode until an occurrence of at least one of (a) the subscriber entering a second predetermined key sequence and (b) the supplemental mode executing to completion.

14. The portable subscriber unit of claim 13, wherein the processing system is further programmed to select the supplemental mode from at least two of the group of supplemental modes.

15. The portable subscriber unit of claim 13, wherein the processing system is further programmed to select the supplemental mode from at least three of the group of supplemental modes.

16. The portable subscriber unit of claim 13, wherein the processing system is further programmed to select the supplemental mode from at least four of the group of supplemental modes.

17. The portable subscriber unit of claim 13, wherein the processing system is further programmed to select the supplemental mode from at least five of the group of supplemental modes.

18. The portable subscriber unit of claim 13,

wherein the processing system is programmed to control the transmitter to send the message from the portable subscriber unit to a receiver in a wireless transmission, in response to keyboard entries made by the subscriber in the predictive menuing mode.
