12. A mobile computing device, comprising:

a touch-sensitive display;

at least one processing apparatus; and

memory that comprises instructions that, when executed by the processing apparatus, cause the processing apparatus to perform a plurality of acts comprising:

displaying a split virtual keyboard on the touch-sensitive display, the split virtual keyboard comprising a first portion displayed at a first position on the touch-sensitive display to facilitate receipt of input thereover from a digit on a first hand, the split virtual keyboard further comprising a second portion displayed at a second position on the touch-sensitive display to facilitate receipt of input thereover from a digit on a second hand, the first portion concurrently displayed with the second portion, the first portion comprising a plurality of keys, the first portion and the second portion of the split virtual keyboard are separated by a non-keyboard portion;

detecting a sequence of strokes over keys in the plurality of keys of the first portion of the split virtual keyboard, wherein a stroke is a continuous transition of the digit on the first hand over the touch-sensitive input panel between respective keys, and wherein the digit on the first hand maintains contact with the touch-sensitive display during the sequence of strokes; and

decoding a word based at least in part upon the detected sequence of strokes.

13. The mobile computing device of claim 12 , the plurality of acts further comprising:

detecting an input gesture on the touch-sensitive display;

responsive to detecting the input gesture, displaying a selectable application, file, or menu option on the touch-sensitive display, wherein the word is employed in connection with searching for or selecting the selectable application, file, or menu option.

14. The mobile computing device of claim 12 , wherein each key in the plurality of keys in the first portion of the split virtual keyboard represents a respective plurality of characters.

15. The mobile computing device of claim 12 , the plurality of acts further comprising:

detecting input over the second portion; and

responsive to detecting the input over the second portion, updating the first portion of the split keyboard.

16. The mobile computing device of claim 15 , wherein updating the first portion of the split virtual keyboard comprises altering a case of characters represented by the plurality of keys from lowercase characters to uppercase characters.

17. The mobile computing device of claim 15 , wherein updating the first portion of the split virtual keyboard comprises altering a language of characters represented by the plurality of keys from a first language to a second language.
