Abstract

A method for selecting a symbol for presentation on a display of a handheld electronic device, comprising: receiving a signal from a key on the handheld electronic device actuated by a user to select a default symbol, the default symbol being one of a plurality of symbols available through actuation of the key; if the actuation of the key is an initial actuation of the key, presenting the plurality of symbols on the display and receiving a signal to select the default symbol from among the plurality of symbols; and, presenting the default symbol on the display.

Claims

1. A method for selecting a symbol for presentation on a display of a handheld electronic device, comprising:

receiving a signal from a key on the handheld electronic device actuated by a user to select a default symbol, the default symbol being one of a plurality of symbols available through actuation of the key;

if the actuation of the key is an initial actuation of the key, presenting the plurality of symbols on the display and receiving a signal to select the default symbol from among the plurality of symbols; and

, presenting the default symbol on the display.

2. The method of claim 1 wherein the symbol is a currency symbol and the key is a currency key.

3. The method of claim 1 wherein the symbol is a parenthesis and the key is a parenthesis key.

4. The method of claim 1 wherein the symbol is a formatting option and the key is a formatting option key.

5. The method of claim 1 wherein the presenting of the default symbol further comprises inserting the default symbol into a text message presented on the display.

6. The method of claim 5 and further comprising determining from a characteristic of the text message whether the default symbol is appropriate and if the default symbol is not appropriate selecting another symbol from among the plurality of symbols for inserting into the text message.

7. The method of claim 6 wherein the characteristic is a language of the text message.

8. The method of claim 6 wherein the characteristic is a use of one or more of the plurality of symbols in a message to which the text message is a reply.

9. The method of claim 1 and further comprising determining from a characteristic of the handheld electronic device whether the default symbol is appropriate and if the default symbol is not appropriate selecting another symbol from among the plurality of symbols as the default symbol.

10. The method of claim 9 wherein the characteristic is a location of the handheld electronic device.

11. The method of claim 6 wherein the characteristic is a context of the text message.

12. The method of claim 1 and further comprising presenting the plurality of symbols on the display and receiving a signal to select the default symbol from among the plurality of symbols.

13. A system for selecting a symbol for presentation on a display of a handheld electronic device, the system comprising:

a processor coupled to the display and to a key on a keypad of the handheld electronic device; and

,

modules executed by the processor, the modules including;

a module for receiving a signal from the key actuated by a user to select a default symbol, the default symbol being one of a plurality of symbols available through actuation of the key;

a module for, if the actuation of the key is an initial actuation of the key, presenting the plurality of symbols on the display and receiving a signal to select the default symbol from among the plurality of symbols; and

,

a module for presenting the default symbol on the display.

14. The system of claim 13 wherein the symbol is a currency symbol and the key is a currency key.

15. The system of claim 13 wherein the symbol is a parenthesis and the key is a parenthesis key.

16. The system of claim 13 wherein the symbol is a formatting option and the key is a formatting option key.

17. The system of claim 13 wherein the module for presenting of the default symbol further comprises a module for inserting the default symbol into a text message presented on the display.

18. The system of claim 17 and further comprising a module for determining from a characteristic of the text message whether the default symbol is appropriate and if the default symbol is not appropriate selecting another symbol from among the plurality of symbols for inserting into the text message.

19. The system of claim 18 wherein the characteristic is a language of the text message.

20. The system of claim 18 wherein the characteristic is a use of one or more of the plurality of symbols in a message to which the text message is a reply.

21. The system of claim 13 and further comprising a module for determining from a characteristic of the handheld electronic device whether the default symbol is appropriate and if the default symbol is not appropriate selecting another symbol from among the plurality of symbols as the default symbol.

22. The system of claim 21 wherein the characteristic is a location of the handheld electronic device.

23. The system of claim 18 wherein the characteristic is a context of the text message.

24. The system of claim 13 and further comprising a module for presenting the plurality of symbols on the display and receiving a signal to select the default symbol from among the plurality of symbols.
