Right-clicking the mouse

That neglected right button on the mouse can give you a shortcut to commands you can't find anywhere else. Unlike the left mouse button, right-clicking will not actually do anything, but will instead show a context menu. The contents of this menu will depend on the program you're working with. To perform an action in the list, put your pointer on the desired command, then click with the left mouse button.

If you're using a Macintosh computer that doesn't have a right mouse button, you can find the context menus by pressing the Control key when clicking.
