摘要

The computer mouse (10) is moved across a support surface for controlling corresponding movement of a cursor relative to a computer monitor display. It has additional controls (18,24) for coordinate displacement and size adjustment of a window section incorporated in the displayed image provided on the monitor screen. One of the additional controls (24) is provided by a roller ball. It controls the up-down and side-to-side movement of the window section. The sliding control (18) is moved in opposite directions for increasing or reducing the size of the window section.
