point
1. (Sometimes abbreviated "pt") The unit of
measurement for {text} {character}s. 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. 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.
