Methods and user interfaces for positioning a selection, selecting, and editing, on a computing device running under a touch-based operating system, using gestures on a touchpad device

A computing device, comprising:

• a display;
• a processor;
• a memory configured to store one or more programs;
• the processor is configured to execute the one or more programs to cause the computing device to:
• receive data from a touchpad device;
• detect a contact on the touchpad device;
• display a selection having a selection length and a selection start point within read-only text content wherein the selection length is one-character length;
• in response to detecting a change in a position of the contact on the touchpad device, change a position of the selection start point within the read-only text content;
• detect a gesture on the touchpad device;
• and in response to detecting a selection gesture, change the selection length within the read-only text content.

A method, comprising:

• at a computing device with a display:
• receiving data from a touchpad device;
• detecting a contact on the touchpad device;
• displaying a selection having a selection length and a selection start point within a content having a content type;
• displaying the selection within the content wherein the selection length is zero-length when the content type is editable text content;
• displaying the selection within the content wherein the selection length is a one-character-length when the content type is read-only text content;
• and
• in response to detecting a change in a position of the contact on the touchpad device, changing a position of the selection start point within the content.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, when executed, cause a computing device with a display to:

• receive data from a touchpad device;
• detect a contact on the touchpad device;
• display a selection having a selection length and a selection start point within a content having a content type;
• display the selection within the content wherein the selection length is zero-length when the content type is editable text content;
• display the selection within the content wherein the selection length is one-character-length when the content type is read-only text content;
• and
• in response to detecting a change in a position of the contact on the touchpad device, change a position of the selection start point within the content.
