| 17. In a computing device, a system, comprising:
a handwriting surface component that receives electronic ink from a digitizer;
a component that provides boundary information corresponding to boundaries of words or characters; and
a scratch-out gesture detector coupled to the handwriting surface component and the component that provides the boundary information,
wherein the scratch-out gesture detector associates a plurality of different scratch-out types with a scratch-out process
that erases previously entered ink that is identified by the scratch-out process and that also erases the electronic ink comprising
the scratch-out gesture, wherein the scratch-out gesture detector also evaluates the electronic ink received at the handwriting
surface against criteria based on the boundary information to determine whether the electronic ink corresponds to any one
of the plurality of different acceptable scratch-out types associated with the scratch-out process.
