A point-and-click gizmo is a device, usually a computer MOUSE, that allows a user to interact with a computer by pointing and clicking on objects on the screen. It is a type of input device that enables a user to select an object or action on the screen by pressing a button on the MOUSE. The term 'point-and-click' refers to the ability to move the cursor to a specific location on the screen and then click the MOUSE button to select an object or action. The MOUSE is the most common type of point-and-click gizmo, but other types of devices such as trackballs, touchpads, and joysticks can also be used.
