What is it?
Shows the Clipboard (sounds only).  

Notes
A sound in the Clipboard can be modified in any way except Cut, Copy, Paste, Paste Over, Paste Mix, and Paste Fit.  

When the Clipboard is not visible, the Clipboard's sound is kept on the hard drive to allow more free RAM.  If you get a memory warning when trying to show the Clipboard, close some windows and try again.
