ABSTRACT:
A method and system for limiting scrolling and the movement of a cursor in a computer application. The computer application is operated on a computer system that has a display device with a display area. The computer application has a work area that is larger than the display area of the display device and a cursor that indicates an active area. Upper and lower and/or left and right boundaries are established by a user. Movement of the cursor is limited to the area of the computer application that is defined by the user-established boundaries. Viewing of the work area of the computer application may also be limited to the area of the computer application that is defined by the user-established boundaries. In a preferred embodiment, the method and system is applied to a computer spreadsheet application.
