<p>PURPOSE:To mark plural optional positions on scroll bars to quickly perform movement between the marks by distinguishing the mark processing function and its operation for displaying the marks on the positions on the scroll bars which correspond to memory content from usual mouse-operations. CONSTITUTION:A mouse-operation decision unit 8 judges whether a mouse- operation operated by a system operator is a mouse-button click in scroll bars 2 or on a mark button 7, or not. When the operation is either one of the above operations, the mouse-operation decision unit has the function of judging whether the operation is either one of mark-setting or release, scrolling to the mark position, usual scroll. A mark-position memory 9 holds position information on the scroll bars 2 which corresponds to the displayed marks. Thus, for window scroll operation, plural parts of an image 4 to be displayed on the memory can be displayed alternately by simple mouse-operations.</p> |
