14. A method comprising: at a computing device with a display and a touch-sensitive input device; receiving handwritten input via the touch-sensitive input device; detecting a set of text characters that correspond to the handwritten input; displaying the handwritten input in a handwriting area on the display; displaying the set of detected text characters in a text area of the display; receiving an input to delete a character; and in response to receiving the input to delete a character: deleting a last detected text character in the text area of the display while maintaining display of one or more detected text characters in the text area of the display; and deleting, in the handwriting area of the display, handwritten input that corresponds to the last detected text character in the text area of the display while maintaining display of handwritten input that corresponds to one or more other text characters in the text area of the display, wherein deleting, in the handwriting area of the display, the handwritten input corresponds to the last detected text character in the text area of the display while maintaining display of the handwritten input that corresponds to one or more other text characters in the text area of the display comprises fading out the handwritten input from the handwriting area that corresponds to the last detected text character in the text area of the display.
