Mac: Screenshots

There are three basic kinds of screenshots: screen, selection, and window.
To take a screen screenshot, use the key combination: Cmd-Shift-3. To take a selection screenshot, use the key combination: Cmd-Shift-4. To take a window screenshot, first hit Cmd-Shift-4, then, tap on the spacebar. (Cmd-Shit-4+Space)


You can save any of the three kinds of screenshots to the clipboard (instead of the Desktop) by adding the Ctrl key to each one. So, instead of Cmd-Shift-3 to take a screen screenshot and saving it to your desktop, Cmd-Ctrl-Shift-3 will save the screenshot to your clipboard.
