The most commonly used button on the mouse is the left click button, with it you can:
Select to perform an action {“click on….”} Position Cursor Click and Drag (move items)We say “click” instead of “left-click” because it is
implied and understood that they mean the same thing.
Double - Click A Double-click also uses the left button,
