How can I use the keyboard to choose how to paste text in MS Word?

While using a word processor I prefer to user the keyboard almost exclusively, but when pasting text in MS Word I seem forced to use the mouse. I can find no way to specify how to treat formatting (keep source / match destination / text only) on a one-off basis without using the mouse (distracting and slow) or altering my default settings (even worse).

Is there a way to do this? It seems to me I need either a keyboard shortcut to enter the Paste Options dialogue after pasting or a different command that I can use to specify the formatting option. I looked at Paste Special, but that only seems to provide one relevant option, namely plain text.

I am using MS Word 2007, but an answer applying to other versions would obviously be more generally useful.
