Some programs will let you view the clipboard more easily than others. If you don't refer to a clipboard program you have to remember to paste the item you clipped before you forget and save something else over it. I've done that more than a few times!

Screen shots don't need extra programs. I typically will hit a simultaneous "alt" and "print screen" (top of the keyboard) to capture whatever is displayed on the active window (so be sure to have it arranged to include everything you want). Then I open Adobe Photoshop and click "new." It knows the size of the image on my clipboard and opens the blank image to that size. I move my mouse over the new background and click "control V" and insert it. And work from there.

Sometimes when you close a program it will tell you that you saved a lot of stuff on your clipboard and ask if you want to save it for later. I've never paid enough attention to access the program at that point, but one of these days maybe I should. It would probably be useful.
