How to capture screenshots in Mac OS X with keyboard shortcuts

While some folks may find the Grab application handy, I prefer to use keyboard shortcuts to take pictures of the screen in Mac OS X. There are a few ways to snapshot your desktop…

Screenshots are saved to the Desktop as PNG file (OS 10.4 and later) or a PDF file (OS 10.3 and prior). To copy the screenshot to the clipboard instead of creating a file on your desktop, hold the Control key in combination with the above keystrokes.

1) To take picture of the entire screen</p> Press Cmd+Shift+3 </td>	2) To take picture of a specific window/object</p> Cmd+Shift+4, then press Spacebar, then Click on the window/object </td> </tr>
	3) To take picture of a selected area</p> Press Cmd+Shift+4 and Click/Drag over desired area While dragging: Hold Spacebar to move selected area. Hold Shift to change size in one direction only (horizontal or vertical) Hold Option for center-based resizing.
