Abstract
Abstract A system for making location adjustments on a display screen raster having horizontal and vertical lines crossing at crossing points includes a cursor which is moveable to the crossing points. The visibility of the cursor is enhanced because the horizontal and vertical lines are brighter than the cursor. The visibility of the cursor can be further enhanced by making the brightness of the cursor adjustable.
