An electronic input device such as an electronic pen is provided to annotate a document. The device may include a recording component that electronically records an annotation of the document, a recognition component that analyzes the annotation and determines whether the annotation includes an electronically-executable instruction, and a processing component that automatically causes an execution of the electronically-executable instruction when the annotation is determined to include an electronically-executable instruction. In another embodiment, a method for processing an annotation of a physical printed version of a document may include obtaining an electronic version of an annotation from a physical printed version of a document, determining if the annotation includes an electronically-executable instruction, and automatically causing an execution of the electronically-executable instruction if the annotation includes an electronically-executable instruction.
