Abstract

A system for, and method of, displaying a sorted list on a display device and a computer incorporating the system or the method. In one embodiment, the system includes: (1) a sort-point identifier that scans a key field of a sorted list and determines sort-points in the key field and (2) a key field marker, associated with the sort-point identifier, that associates marks with the key field based on the sort-points and causes at least a portion of the sorted list and the associated marks to be displayed on the display device.

Claims

1. A system for displaying a sorted list on a display device, comprising:

a sort-point identifier that scans a key field of a sorted list and determines sort-points in said key field; and

a key field marker, associated with said sort-point identifier, that associates marks with said key field based on said sort-points and causes at least a portion of said sorted list and said associated marks to be displayed on said display device.

2. The system as recited in claim 1 wherein said marks are selected from the group consisting of:

alphanumeric characters,

special characters,

graphics characters,

icons,

typefaces, and

text attributes.

3. The system as recited in claim 1 wherein said marks are spaces separating said sort-points.

4. The system as recited in claim 1 wherein said sort-point identifier and said key field marker are associated with a computer program selected from the group consisting of:

an electronic mail program,

a word processor,

a contact manager, and

an operating system.

5. The system as recited in claim 1 wherein said key field is selectable.

6. The system as recited in claim 1 wherein said key field is selected from the group consisting of:

sender name,

date sent,

subject,

filename,

file extension,

file size,

file type,

date created, and

date modified.

7. The system as recited in claim 1 further comprising a computer having data processing and storage circuitry and said display device.

8. A method of displaying a sorted list on a display device, comprising:

scanning a key field of a sorted list;

determining sort-points in said key field;

associating marks with said key field based on said sort-points; and

causing at least a portion of said sorted list and said associated marks to be displayed on said display device.

9. The method as recited in claim 8 wherein said marks are selected from the group consisting of:

alphanumeric characters,

special characters,

graphics characters,

icons,

typefaces, and

text attributes.

10. The method as recited in claim 8 wherein said marks are spaces separating said sort-points.

11. The method as recited in claim 8 wherein said scanning, determining, associating and causing are carried out in a computer program selected from the group consisting of:

an electronic mail program,

a word processor,

a contact manager, and

an operating system.

12. The method as recited in claim 8 further comprising selecting said key field.

13. The method as recited in claim 8 wherein said key field is selected from the group consisting of:

sender name,

date sent,

subject,

filename,

file extension,

file size,

file type,

date created, and

date modified.

14. The method as recited in claim 8 wherein said scanning, determining, associating and causing are carried out in a computer having data processing and storage circuitry and said display device.

15. A computer, comprising:

data processing and storage circuitry that contains a sorted list;

a display device capable of displaying said sorted list; and

a system for displaying said sorted list on said display device, including;

a sort-point identifier that scans a key field of said sorted list and determines sort-points in said key field, and

a key field marker, associated with said sort-point identifier, that associates marks with said key field based on said sort-points and causes at least a portion of said sorted list and said associated marks to be displayed on said display device.

16. The computer as recited in claim 15 wherein said marks are selected from the group consisting of:

alphanumeric characters,

special characters,

graphics characters,

icons,

typefaces, and

text attributes.

17. The computer as recited in claim 15 wherein said marks are spaces separating said sort-points.

18. The computer as recited in claim 15 wherein said sort-point identifier and said key field marker are associated with a computer program selected from the group consisting of:

an electronic mail program,

a word processor,

a contact manager, and

an operating system.

19. The computer as recited in claim 15 wherein said key field is selectable.

20. The computer as recited in claim 15 wherein said key field is selected from the group consisting of:

sender name,

date sent,

subject,

filename,

file extension,

file size,

file type,

date created, and

date modified.
