I like my mac to do documentations and photo editing.
For my next week’s training preparation, I had to do a lot of screenshots.
With Windows and Linux, it is quite straight forward to take a screenshot, but realized that it wasn’t as straight forward.
Followings are the key shortcuts that I found through google 
- Command-Shift-3: Take a screenshot of the screen, 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-4, then space, then click a window: Take a screenshot of a window and save it as a file on the desktop
- Command-Control-Shift-3: Take a screenshot of the screen, 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-4, then space, then click a window: Take a screenshot of a window and save it to the clipboard
