Did you know that you can take a snapshot of how your screen looks?
You can copy the currently active window to the clipboard by pressing ALT + PrintScreen or you can copy the whole screen with CTRL + Print Screen. You can then paste the picture into your Word Processor or Graphics software. Why might you want to do that? Well one reason is to capture those error messages to pass on to someone who might be able to help sort it out without you having to remember the jargon of the message.
Another use for this is one I used a lot recently when writing my latest e-book, "Windows Without a Mouse". You can buy it from www.withoutamouse.com, by the way.
