## Abstract

An attribute-enhanced scroll bar is graphically displayed. A selected portion of a stored data file, for example a document, is displayed in a display field, and a scroll bar field including a scroll bar is used to indicate the position of the displayed portion relative to the entire data file. In addition, maps of significant task-specific attributes of the data file, for example particular character strings within a document, are displayed in the scroll bar field of the display along with the scroll bar. The attribute maps indicate the location of the significant attributes within the data file. In addition, the attributes are highlighted within the portion of the data file that is displayed in the display field.
