I am looking for a clipboard viewer for OS X which will show all formats that the clipboard is holding the data in. (I.e. something similar to the Clipbook viewer in Windows XP.)
I found a number of programs that show the contents of the clipboard, but I haven't been able to find one which lists all formats available on the clipboard at the moment, and makes it possible to extract either of them. I believe the OS X clipboard can hold the data in multiple formats simultaneously, just like Windows (e.g. in MS Word there's a Paste special... menu item which allows selecting the format to paste).
