13. A method for testing input device attributes, the method comprising: receiving first input on an input surface via an input device; determining if the received first input is associated with a scribble input for determining attributes of the input device based on a location corresponding to a margin of an electronic document of the received first input on the input surface; in response to determining that the received first input is associated with the scribble input, making a determination whether to erase the scribble input, wherein making the determination to erase the scribble input comprises: receiving a second input via the input device; evaluating a location of the second input to the scribble input; determining that the location of the second input to the scribble input is not in the margin of the electronic document; and determining, based on the location of the second input, that the second input is not a continuation of the scribble input; and based on the received first input being associated with the scribble input, erasing the scribble input, but not the second input, after a predetermined amount of time after receiving the scribble input.
