Keyboard gestures for character string replacement

1. A method comprising:

responsive to receiving an indication of a first user input, outputting, by the computing device and for display, text that is based on the first user input;

determining, by the computing device and based at least in part on the first user input, a list of one or more suggested character strings;

responsive to receiving an indication of a second user input, determining, by the computing device, whether the received second user input includes a replacement gesture, wherein the replacement gesture includes a first gesture in a first direction and a second gesture in a second direction that is substantially opposite to the first direction; and

responsive to determining that the received second user input includes the replacement gesture, outputting, by the computing device and for display, in place of the text, a character string from the list of one or more suggested character strings.

2. The method of claim 1 , wherein the character string from the list of one or more suggested character strings is ranked higher than at least one other character string from the list of one or more suggested character strings, the list of one or more suggested character strings being organized in a ranked order.

3. The method of claim 1 , wherein the first direction is a substantially leftward direction and wherein the second direction is a substantially rightward direction.

4. The method of claim 3 , wherein the first direction is substantially parallel with the second direction.

5. The method of claim 1 , wherein the character string is a first character string in the list of one or more suggested character strings, wherein the list of one or more suggested character strings is an ordered list.

6. The method of claim 1 , wherein the second gesture is received subsequent to the first gesture.

7. The method of claim 1 , further comprising:

ranking, by the computing device, the list of one or more suggested character strings such that a highest-ranked character string in the list of one or more suggested character strings is a most-probable match to the indication of the first user input.

8. The method of claim 1 , wherein the list of one or more suggested character strings is displayed in a ranked order.

9. The method of claim 8 , wherein the character string is a highest ranked character string from the list of one or more suggested character strings that are ranked in the ranked order.

10. The method of claim 1 , wherein the replacement gesture is entered by a user at a presence-sensitive display that is operatively coupled to the computing device.

11. A device comprising:

at least one processor; and

at least one module operable by the at least one processor to:

responsive to receiving an indication of a first user input, output, for display, text that is based on the first user input;

determine, based at least in part on the first user input, a list of one or more suggested character strings;

responsive to receiving an indication of a second user input, determine whether the received second user input includes a replacement gesture, wherein the replacement gesture includes a first gesture in a first direction, and a second gesture in a second direction that is substantially opposite to the first direction; and

responsive to determining that the received second user input includes the replacement gesture, output, for display, in place of the text, a character string from the list of one or more suggested character strings.

12. The device of claim 11 , wherein the character string from the list of one or more suggested character strings is ranked higher than at least one other character string from the list of one or more suggested character strings, the list of one or more suggested character strings being organized in a ranked order.

13. The device of claim 11 , wherein the first direction is a substantially leftward direction and wherein the second direction is a substantially rightward direction.

14. The device of claim 11 , wherein the first direction is substantially parallel with the second direction.

15. The device of claim 11 , wherein the list of one or more suggested character strings is displayed in a ranked order.

16. A non-transitory computer-readable storage medium encoded with instructions that, when executed, cause at least one processor of a computing device to perform operations comprising:

responsive to receiving an indication of a first user input, outputting, for display, text that is based on the first user input;

determining, based at least in part on the first user input, a list of one or more suggested character strings;

responsive to receiving an indication of a second user input, determining, whether the received second user input includes a replacement gesture, wherein the replacement gesture includes a first gesture in a first direction and a second gesture in a second direction that is substantially opposite to the first direction; and

responsive to determining that the received second user input includes the replacement gesture, outputting, for display, in place of the text, a character string from the list of one or more suggested character strings.

17. The non-transitory computer-readable storage medium of claim 16 , wherein the character string from the list of one or more suggested character strings is ranked higher than at least one other character string from the list of one or more suggested character strings, the list of one or more suggested character strings being organized in a ranked order.

18. The non-transitory computer-readable storage medium of claim 16 , wherein the first direction is a substantially leftward direction and wherein the second direction is a substantially rightward direction.

19. The non-transitory computer-readable storage medium of claim 16 , wherein the first direction is substantially parallel with the second direction.

20. The non-transitory computer-readable storage medium of claim 16 , wherein the list of one or more suggested character strings is displayed in a ranked order.
