Take Screenshots in Mac OS X

Rather than having a single Print Screen key to copy the entire desktop to the clipboard like in Windows, OS X has a series of key combinations that you can use to perform various screenshotting tasks.

• Command + Shift + 3: Takes a screenshot and saves it on the desktop
• Command + Shift + 4: Allows you to select a portion of the screen and saves it on the desktop
• Command + Shift + 4, then space bar: Allows you to select a window and saves it on the desktop

• Command + Control + Shift + 3: Takes a screenshot and saves it on the clipboard
• Command + Control + Shift + 4: Select a portion of the screen and saves it on the clipboard
• Command + Control + Shift + 4, then space bar: Select a window and saves it on the clipboard

Aside from using those key combinations, OS X has its own utility for taking screenshots called Grab. It supports several features like timed capture and the ability to change the pointer type when taking the screenshot. The application is located at /Applications/Utilities/Grab.
