Using the Snip Tool

There is a program called Snip that will let you capture screenshots to put in documents or send as e-mail.

To access it, simply open the Startup Menu and type SNIP

Next to the New button, click on the down-arrow and select what type of capture you want to do, Free Form, Rectangular, Window or Full-Screen.

Once you capture the screen, you can save it as a HTML, PNG, GIF or JPG
