A computer program is described which makes it easier for a computer programmer to view and understand the source code of other programs. The user can look up the definition of, or references to, a name without typing the name. After the name has been looked up, the user can return automatically to his original location in the text. Multiple return locations are saved. The invention incorporates knowledge of the syntax of the programming language and creates an internal cross-reference. As a result, lookups are rapid and accurate.
