But creating screenshots this way often means you need to crop or clean up the edges of the image later. That’s especially true if you’re planning to use it as a graphic element in a document or presentation. Fortunately, Mac OS X Leopard offers a way to save clean screenshots of individual elements on your desktop — such as Finder windows, menus, icons, or the visible portion of an open document — without capturing anything else in the background.
Hold down the Command, Shift, and 4 keys, then press the Spacebar. Instead of a cross-hair cursor, a small camera icon appears. When you move this camera icon over the element you’d like to capture, that element is highlighted. Click your mouse or trackpad, and you’ve captured a screenshot of just that element — no further cleanup required.
