Users being upgraded from Windows XP to Windows 7 will receive, among many other upgrades and enhancements, a great built-in way to take screen shots. Since the early days of Windows, using the Print Screen button, located in the upper right corner of your keyboard, was a quick way to grab the entire contents of your screen into your system’s clipboard. You can still do that under Windows 7, but a new tool, the Snipping Tool, is also available. To find it, go to your Start button and then type “Snip” in the search area. The first tool that comes up should be the Snipping Tool. When you launch it, it allows you to create a new snip by dragging a box around any area of your screen. Then, you can either save it as a graphic file or copy it to your clipboard. Very handy!
Veteran Mac users will note that this capability has been built-in to the Mac OS for years. On the Mac, use Command-Shift-3 to take a whole-screen shot (which is dropped as a file on your desktop) or use Command-Shift-4 to snip out a region of your screen.
