Mac OSX: How to take a screenshot

Bloody hell, this garbage ain't user friendly at all!

These save an image the desktop:

• Command + Shift + 3
  Take a screenshot of the whole screen
• Command + Shift + 4, then select an area
  Take a screenshot of the selected area
• Command + Shift + 4, then Spacebar, then click a window
  Take a screenshot of a window

To copy it to the clipboard, use the Shift key with the combinations above.

In Leopard and later, the following keys can be held down while selecting an area:

• Space
  Move the selected region
• Shift
  Resize only one edge of the selected region
• Option
  Resize the selected region with its center as the anchor point
