Do you ever want to send a shot of part of your screen to your developer or someone?
If you have Windows 7 there is a “snipping” that you can use.
Go to your Start menu, type “snipping” in the search box and it should come up. Then you highlight the part of the screen you want and copy or send it off. You can also highlight or use the pen to annotate the image before you send it.
If you want to use a whole screen shot you can also use Alt / Print Screen and then paste into a document or email.
