Abstract:

A data processing system provides annotation of a document through an electronic tablet, a keyboard and an audio assembly. An annotatable document is generated from a window of a multiwindow support program running independently of the annotation program in the data processing system. For each window of the multiwindow program, a working document is generated and is annotatable by the annotation program and apparatus. An annotatable document is also generated from the whole screen view of overlapping windows produced during execution of the multiwindow support program. Annotated working documents may be subsequently stored in and thereafter retrieved from the database of the multiwindow support program.
