Take pictures of the screen
You can take pictures (called screenshots) of the whole screen or a part of it by pressing certain keys on the keyboard. For example, to take a picture of the whole screen, press Shift-Command-3.
Screenshots are saved automatically as .png files on the desktop; the filename begins with “Screen Shot” and includes the date and time it was taken.
Tip: To copy a screenshot so you can paste it somewhere—like in an email or to another device—press and hold the Control key while you press the other keys. For example, to copy the whole screen, press Shift-Command-Control-3.

To cancel, press Escape before you release the mouse button.
