In Mac OS X 5 (Leopard) or more recent, the following keys can be held down when selecting an area (with either Command-Shift-4 or Command-Control-Shift-4): Command-Control-Shift-4, then space, then click on a window: Take a screenshot of a selected window and save it to the clipboard.Command-Control-Shift-4, then select an area: Take a screenshot of an area and save it to the clipboard.Command-Control-Shift-3: Take a screenshot of the screen and save it to the clipboard.Command-Shift-4, then space, then click on a window: Take a screenshot of a selected window and save it as a file on the desktop.

Command-Shift-4, then select an area: Take a screenshot of an area and save it as a file on the desktop.Command-Shift-3: Take a screenshot of the entire screen and save it as a file on the desktop.With Mac OS X 10.6 (Snow Leopard) the default name changes to Screen shot YYYY-MM-DD at HH.MM.SS XM, where YYY=year, MM=month, DD=day, HH=hour, MM=minute, SS=second, and XM = either AM or PM. If you have multiple monitors connected, each monitor is saved as a separate picture, named Picture 1, Picture 1(2), Picture 1(3), etc. Command-Shift-3 takes a screenshot of the screen and saves it as a file to the desktop under the name of Picture 1 (or next available number if there are already screenshots saved there). The normal method for obtaining a screen capture is through the graphic user interface. Screencapture creates an image of the screen or a portion of the screen.

This subchapter looks at screencaptures, a Mac OS X-only command.
