A method is described which improves the speed of wide-area cursor positioning without using a mouse. In accordance with the new method, imagine the keyboard is over-laid on the display, so each key maps to a specific point. Any key pressed simultaneously with a cursor key moves the cursor to the corresponding point on the screen. Past cursor-positioning methods include off-screen positioners such as a mouse or joystick, on-screen touch sensitive sensors, and the classical method of typamatic cursor keys and lots of time. The new method provides the low cost and compactness of a keyboard-only cursor-positioning system. Because it uses only a keyboard, it has compatibility across all products. However, it still provides the speed of a mouse system for cursor positioning.
