1. <text, unit> (Sometimes abbreviated "pt") The unit of measurement for text characters. One point is 1/72 inches (approx 0.35mm) so 12 point text would be 1/6th inch (approx 4.2mm) high when printed.
2. <hardware> To move a pointing device so that the on-screen pointer is positioned over a certain object on the screen such as a button in a graphical user interface. In most window systems it is then necessary to click a (physical) button on the pointing device to activate or select the object. In some systems, just pointing to an object is known as "mouse-over" event which may cause some help text (called a "tool tip" in Windows) to be displayed.
