Screen Capturing on a Mac
I always forget these shortcut keys, but they are extremely useful. Why all modern OS’s (uhh hemm, Windows) hasn’t integrated this robust functionality directly into their desktop manager is an oversight in my opinion.
The following commands will store the capture directly to the desktop, if you add Control into the key sequence then it will copy the capture to the clipboard instead.
Command-Shift-3 :: Full desktop capture
Command-Shift-4 :: Select what you want to capture
Note: If you are looking for a free alternative on Windows then Greenshot is good and has similar screen capturing capabilities as SnagIt.
