In the Windows world, the concept of Right Click and Left Click is everywhere.
This is what you should remember –
LEFT CLICK – do something. This is the most common way to click.
RIGHT CLICK – get more information or more options. This is much less common.
On a Macintosh computer, the mouse generally does not have two methods of clicking. Clicking the mouse is the same as LEFT CLICK. If you want to do the equivalent of a RIGHT CLICK, hold down the Control key while you click.
Good luck!
