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.
