Answer 1

Answer:

A double-click is the act of pressing a computer mouse button twice quickly without moving the mouse. Double-clicking allows two different actions to be associated with the same mouse button. It was developed by Bill Atkinson of Apple Computer (now Apple Inc.) for their Lisa project.[1] Often, single-clicking selects (or highlights) an object, while a double-click executes the function associated with that object.
