How to take a ScreenShot in gile[s]

I know this is probably a dumb question here...
But I havn't found anything in gile[s] that will
allow me to take a screenshot of a level im' designing!
Can someone please tell me how this is done?

Thank's a million guys!

Hit the Printscreen button on your keyboard. Now go into an image editing app (eg. Photoshop,) create a new image, and paste.

ok... thanks man!

Alt+PrintScreen if you only want to capture the active window.
