Taking pictures of your screen is not as simple as pressing the Print Screen button, like you do when working with Windows. Rather, taking shots of your screen on the Mac requires that you memorize a rather long and unintuitive keystroke combination. For instance:
To take a picture of part of the screen to clipboard: Command + Control + Shift + 4
To take a picture of the entire screen: Command + Shift + 3 (add Control key to save to the clipboard)
An easier (and my preferable) way is to add a keyboard shortcut to the command in the Keyboard Shortcuts area of the System Preferences.
- Click the Apple icon on your screen and select System Preferences.
- Click “Keyboard” under the Hardware area.
- Click the Keyboard Shortcuts tab.
- Click “Screen Shots” in the left pane.
- In the right pane, double-click the shortcut you wish to change.
- Type in the new keyboard shortcut.
In the example above, I have changed the Copy picture of selected area to the clipboard command to execute whenever I press the F6 key. That is to say, that whenever I press the F6 key, the mouse pointer transforms into a crosshair pointer, allowing me to select a specific area of the screen and then copy it to the clipboard (the same result as the Command + Control + Shift + 4 shortcut).
