ClipMate Clipboard Extender U3 Edition

From Thornsoft Development:

Although the Windows clipboard is great for cutting and pasting one item at a time, often you need to work with more than one item or you may need to print, edit, re-format, or even spell check your data before pasting. ClipMate has functions to combine, edit, and manage your clipboard data. It can also print, re-format, and even spell-check. It also has a multi-monitor screen capture, and has features for sharing clips among multiple PCs.

ClipMate can run completely self-contained from USB Thumb Drives, including the ones running the "U3 Smart" launchpad and the PortableApps menu. When in portable mode, ClipMate does not need to be installed on the host computer, nor will it leave licensing information behind.
