Abstract

A device and method provide for maintenance of a shortcut key to an application accessible at the device. The method includes assigning a first application to a shortcut key at a device, wherein the shortcut key at the device is a button on the device; storing an identifier of the first application to a first file at the device; determining if the first application at the device assigned to the shortcut key remains executable at the device; if the first application is determined to be unexecutable at the device, assigning a second application to the shortcut key at the device, wherein an identifier of the second application is stored in a second file at the device, and further wherein the second application is executable at the device.

Claims

1. A computerized method for maintaining a shortcut key to an application accessible at a device, the method comprising:

assigning a first application to a shortcut key at a device,

storing an identifier of the first application to a first file at the device;

determining if the first application at the device assigned to the shortcut key remains executable at the device; and

if the first application is determined to be unexecutable at the device, assigning a second application to the shortcut key at the device, wherein an identifier of the second application is stored in a second file at the device, and further wherein the second application is executable at the device.

2. The method of claim 1, further comprising:

storing an identifier of a third application to a third file at the device;

selecting the identifier of the third application from the third file if neither the first application nor the second application is executable at the device; and

assigning the third application to the shortcut key at the device if neither the first application nor the second application is executable at the device.

3. The method of claim 1, further comprising:

if the first application is determined to be unexecutable at the device, assigning the first application to the shortcut key at the device if the first application subsequently is determined to be executable at the device

4. The method of claim 1, upon a request from a user to assign a third application to the shortcut key, assigning the identifier of the third application to the first file, assigning the identifier of the first application to the second file, and assigning the identifier of the second application to a third file wherein the third application is assigned to the shortcut key if the third application is executable at the device, or the first application is assigned to the shortcut key if the third application is unexecutable at the device but the first application is executable at the device or the second application is assigned to the shortcut key if the third and first applications are unexecutable at the device but the second application is executable at the device.

5. The method of claim 1, wherein the first application executes from a multi-media card.

6. The method of claim 1, wherein the shortcut key comprises a scroll key.

7. The method of claim 6, wherein the scroll key comprises a five-way scroll key.

8. The method of claim 1, wherein the shortcut key is a button on the device but is not a button included with a numeric keypad at the device.

9. One or more computer-readable media having computer-readable instructions stored thereon that, upon execution by a processor, cause the processor to maintain a shortcut key to an application accessible at a device, the instructions configured to

assign a first application to a shortcut key at a device,

store an identifier of the first application to a first file at the device;

determine if the first application at the device assigned to the shortcut key remains executable at the device;

if the first application is determined to be unexecutable at the device, assign a second application to the shortcut key at the device, wherein an identifier of the second application is stored in a second file at the device, and further wherein the second application is executable at the device.

10. The computer readable media of claim 9, further comprising computer readable instructions configured for:

storing an identifier of a third application to a third file at the device;

selecting the identifier of the third application from the third file if neither the first application nor the second application is executable at the device; and

assigning the third application to the shortcut key at the device if neither the first application nor the second application is executable at the device.

11. The computer readable media of claim 9, further comprising computer readable instructions configured for:

if the first application is determined to be unexecutable at the device, assigning the first application to the shortcut key at the device if the first application subsequently is determined to be executable at the device

12. The computer readable media of claim 9, further comprising computer readable instructions configured for:

upon a request from a user to assign a third application to the shortcut key, assigning the identifier of the third application to the first file, assigning the identifier of the first application to the second file, and assigning the identifier of the second application to a third file wherein the third application is assigned to the shortcut key if the third application is executable at the device, or the first application is assigned to the shortcut key if the third application is unexecutable at the device but the first application is executable at the device or the second application is assigned to the shortcut key if the third and first applications are unexecutable at the device but the second application is executable at the device.

13. A device for maintaining a shortcut key to an application accessible at a device, the device comprising:

a shortcut key,

a first file;

a second file;

a first application, wherein the first application is removable from the device;

a second application;

a utility, the utility comprising computer code configured to assign the first application to the shortcut key;

store an identifier of the first application to the first file;

determine if the first application assigned to the shortcut key remains executable at the device; and

if the first application is determined to be unexecutable at the device, assign the second application to the shortcut key, wherein an identifier of the second application is stored in the second file, and further wherein the second application is executable at the device;

a memory, wherein the memory stores the utility, the first file, and the second file; and

a processor, the processor coupled to the memory and configured to execute the utility.

14. The device of claim 13, wherein the utility further comprising computer code configured for:

storing an identifier of a third application to a third file at the device;

selecting the identifier of the third application from the third file if neither the first application nor the second application is executable at the device; and

assigning the third application to the shortcut key at the device if neither the first application nor the second application is executable at the device.

15. The method of claim 13, wherein the utility further comprising computer code configured for:

if the first application is determined to be unexecutable at the device, assigning the first application to the shortcut key at the device if the first application subsequently is determined to be executable at the device

16. The method of claim 13, wherein the utility further comprising computer code configured for upon a request from a user to assign a third application to the shortcut key, assigning the identifier of the third application to the first file, assigning the identifier of the first application to the second file, and assigning the identifier of the second application to a third file wherein the third application is assigned to the shortcut key if the third application is executable at the device, or the first application is assigned to the shortcut key if the third application is unexecutable at the device but the first application is executable at the device or the second application is assigned to the shortcut key if the third and first applications are unexecutable at the device but the second application is executable at the device.
