Capture your screen

> To shoot a screenshot, use Shift+Command+3. The resulting document will be sent to your desktop. To capture a window, use Shift+Command+4, press Space and then click the window.

To grab a portion of the screen, use Shift+Command+4 and drag a selection. Prior to letting go of the mouse/trackpad button, which shoots the grab, you can move the selection box by holding Space and dragging. Hold Option to expand the selection from the centre, or Shift to limit expansion to horizontal or vertical only, depending in which direction you next move the cursor.

Shift+Command+5 brings up a capture interface, with buttons for aforementioned features and those for videoing the entire screen or a portion. Also explore the Options menu, which enables you to set a timer, toggle whether the pointer is visible in screenshots, and define where screenshots are saved. Consider using a Screenshots folder in iCloud Drive to make them immediately accessible across all your devices.
