Abstract

A method includes, detecting a location of a text selection icon on a display of an electronic device, and, detecting touch input representing a selection of text displayed on the display using the text selection icon, wherein: if the detected location of the text selection icon is maintained within a zone adjacent an edge of the display, the displayed text is selected on a row by row basis, and, if the detected location of the text selection icon moves outside said zone, the displayed text is selected on a letter by letter basis.

Claims

1. A method comprising:

detecting a location of a text selection icon on a display of an electronic device;

detecting a touch input representing a selection of text displayed on the display using the text selection icon;

determining a movement of the text selection icon while the touch input is maintained during the movement, wherein the movement is continuous and drags the text selection icon into a zone adjacent an edge of the display;

in response to the determination, enabling a row by row selection mode; and

during the movement of the text selection icon while the touch input is maintained and the row by row selection mode is enabled, dynamically increasing a width of said zone based on at least one of a number of rows of displayed text selected by the continuous movement of the text selection icon or a speed of the movement;

wherein;

if the detected location of the text selection icon is maintained within said zone during the movement while the touch input is maintained, the displayed text is selected on a row by row basis; and

,

if the detected location of the text selection icon moves outside said zone and moves into the displayed text during the movement while the touch input is maintained, the row by row selection mode is switched to a letter by letter selection mode, wherein in the letter by letter selection mode the displayed text is selected on a letter by letter basis.

2. A method according to claim 1, wherein the text selection icon is a text selection cursor.

3. A method according to claim 1, wherein the text selection icon is a text selection handle.

4. A method according to claim 1, wherein the touch input is a drag of the text selection icon.

5. A method according to claim 1, wherein the selected text is highlighted on the display.

6. A method according to claim 1, wherein the display is a touch-sensitive display.

7. A method according to claim 1, wherein the touch input is detected on a track pad.

8. A method according to claim 1, wherein the touch input is detected on a touch-sensitive display.

9. A method according to claim 1, wherein the displayed text selected after the text selection icon moves outside said zone is selected on a letter by letter basis while the text selected on the row by row basis remains selected after the text selection icon moves outside said zone.

10. An electronic device comprising:

a display;

at least one processor operable when executed to perform the following operations;

detect a location of a text selection icon on the display;

detect a touch input representing a selection of text displayed on the display using the text selection icon;

determine a movement of the text selection icon while the touch input is maintained during the movement, wherein the movement is continuous and drags the text selection icon into a zone adjacent an edge of the display;

in response to the determination, enable a row by row selection mode; and

during the movement of the text selection icon while the touch input is maintained and the row by row selection mode is enabled, dynamically increase a width of said zone based on at least one of a number of rows of displayed text selected by the continuous movement of the text selection icon or a speed of the movement;

wherein;

if the detected location of the text selection icon is maintained within said zone during the movement while the touch input is maintained, the displayed text is selected on a row by row basis; and

,

if the detected location of the text selection icon moves outside said zone and moves into the displayed text during the movement while the touch input is maintained, the row by row selection mode is switched to a letter by letter selection mode, wherein in the letter by letter selection mode the displayed text is selected on a letter by letter basis.

11. The electronic device according to claim 10, wherein the text selection icon is a text selection cursor.

12. The electronic device according to claim 10, wherein the text selection icon is a text selection handle.

13. The electronic device according to claim 10, wherein the touch input is a drag of the text selection icon.

14. The electronic device according to claim 10, wherein the selected text is highlighted on the display.

15. The electronic device according to claim 10, wherein the display is a touch-sensitive display.

16. The electronic device according to claim 10, wherein the touch input is detected on a track pad.

17. The electronic device according to claim 10, wherein the touch input is detected on a touch-sensitive display.

18. A non-transitory computer-readable medium containing instructions which, when executed by a processor, cause an electronic device to perform operations comprising:

detecting a location of a text selection icon on a display of the electronic device;

detecting a touch input representing a selection of text displayed on the display using the text selection icon;

determining a movement of the text selection icon while the touch input is maintained during the movement, wherein the movement is continuous and drags the text selection icon into a zone adjacent an edge of the display;

in response to the determination, enabling a row by row selection mode; and

during the movement of the text selection icon while the touch input is maintained and the row by row selection mode is enabled, dynamically increasing a width of said zone based on at least one of a number of rows of displayed text selected by the continuous movement of the text selection icon or a speed of the movement;

wherein;

if the detected location of the text selection icon is maintained within said zone during the movement while the touch input is maintained, the displayed text is selected on a row by row basis; and

,

if the detected location of the text selection icon moves outside said zone and moves into the displayed text during the movement while the touch input is maintained, the row by row selection mode is switched to a letter by letter selection mode, wherein in the letter by letter selection mode the displayed text is selected on a letter by letter basis.
