When using a computer, ‘mouse over’ refers to the action of moving the cursor over an object or element on the screen, typically causing a change in appearance or displaying additional information. This can be done by hovering the mouse pointer over the object without clicking. It is often used to preview or access hidden features, links, or menus, making it a convenient and efficient way to interact with digital content. The term ‘mouse over’ is derived from the physical motion of moving a computer mouse over a surface to control the cursor on the screen.
