The following commands in Mac are very useful to capture screenshots:
- Command-Shift-3 – Taking a screen capture of your entire screen
- Command-Shift-4 – Giving you a crosshair cursor so you can choose which area of the screen you want to capture
- Control-Command-Shift-3 – Same as 1, but copy the image to clipboard rather than saving as an image
- Control-Command-Shift-4 – Same as 2, but copy the image to clipboard rather than saving as an image
They are really handy and can save people lots of time.
