One of the keyboard shortcuts we use the most on our Mac is the screenshot shortcut:
Full Screen Shot: Command + Shift + 3
This will take a picture of your entire screen. You can find the screenshot on your desktop.
Crosshairs Screen Shot: Command + Shift + 4
This turns your cursor into crosshairs that let you isolate which part of the screen you’d like to take a picture of and adds the screen shot to your desktop.
Screenshots are a great way to save images from web sites or take a picture of an error message that pops up on your screen, but they can quickly crowd your desktop that’s where the Little Snapper App comes in. Little Snapper is like iPhoto for screenshots. It allows you to organize, rename, share all your screenshots easily.
