And that command works even if the window you want to capture is somewhat behind another window. In short, the window you want to capture doesn't have to be the active one. Let Windows 7 beat THAT! :cool:
 
From Apple's Tip of the Week:

Okay, you probably already know the ol’ Command-Shift-3 shortcut for taking a screen capture of your entire screen, and you may even know about Command-Shift-4, which gives you a crosshair cursor so you can choose which area of the screen you want to capture. But perhaps the coolest, most-secret hidden capture shortcut is Control-Command-Shift-3 (or 4), which, instead of creating a file on your desktop, copies the capture into your Clipboard memory, so you can paste it where you want.
 
The newer Apples dont use the ":apple:" logo fo the command button.. just so you remember ;)

REALLY!? That just makes it even MORE confusing! Especially for my friends that use PC's and have no idea about the keyboard shortcuts on Macs.

It's not that confusing when you see it, there is a command, or apple key, followed by "option" and "control". The command key is the main modifier like Windows' Alt key. It's not difficult to get used to.



At first I thought the mac screenshots were difficult with the button combos but if you use them enough they're simple and more efficient that Windows (up to XP, not so sure about Vista/7). In Windows it is one button, the print screen button -- but I have to open paint, and paste it there, then save the image.

In OS X, I hit CMD+Shift+3 and the desktop is automatically saved as a picture for me, simple. The ones i use most are:


CMD+Option+3 for the entire screen
CMD+Option+4 (then select an area) for specific areas or windows
CMD+Option+4+Spacebar to select a window and snap just that
