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 dominant 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.
