Abstract

A method includes displaying information on a touch-sensitive display, detecting a touch at location associated with the information, rendering an indicator and a cursor at a position within the information, detecting a moving touch associated with the indicator, and moving the cursor along the information as the indicator is moved.

Claims

1. A method comprising:

displaying information on a touch-sensitive display;

detecting a first touch at a first location associated with the information;

rendering a first indicator at a first position within the information when the first touch is detected;

when a second touch is detected at a second location associated with the information, rendering a second indicator at a second position and highlighting information that is displayed between the first position and the second position

wherein a majority of one of the first and second indicators is oriented above an earliest part of the highlighted information, and wherein a majority of an other of the first and second indicators is oriented below a latest part of the highlighted information; and

detecting crossing movement of the first and second indicators, and switching orientations of the first and second indicators.

2. The method according to claim 1, comprising rendering a marker at the position within the information prior to detecting the second touch.

3. The method according to claim 1, comprising moving a marker along the information as the first indicator is moved.

4. The method according to claim 1, comprising changing the first indicator when the second indicator is rendered.

5. The method according to claim 1, comprising, when the first indicator moves to a third position in the information, highlighting the information that is displayed between the third position and the second position.

6. The method according to claim 1, comprising, when the second indicator is moved to a third position in the information, highlighting the information that is displayed between the first position and the third position.

7. A computer-readable storage medium having computer-readable code executable by at least one processor of a portable electronic device to perform the method according to claim 1.

8. The method according to claim 1, wherein the first touch and the second touch overlap at least partially in time.

9. The method according to claim 1, wherein the indicator at least partially surrounds a marker.

10. The method according to claim 1, comprising determining an applied force of the touch on the touch-sensitive display, wherein the indicator is rendered in response to determining that the applied force exceeds a threshold.

11. The method according to claim 1, comprising detecting a moving touch associated with a part of the first indicator, which part is spaced from the first location, and moving the first indicator within the information based on the moving touch.
