    摘要: In one aspect, a device instructions executable by a processor to present, on a touch-enabled display at a first location, a first representation of at least a portion of first handwriting input. The instructions are executable to identify at least a first characteristic related to the first handwriting input, receive first input pertaining to second handwriting input, and in response to receipt of the first input, present on the touch-enabled display at a second location a second representation of at least a portion of the second handwriting input. The instructions are executable to receive second input to present at least a portion of the second representation at least adjacent to the first location and, in response to receipt of the second input and without receiving further input from a user, present at least the portion of the second representation at least adjacent to the first location using the first characteristic.
