How to repeat currently typed in parameter on Bash console?

I was just typing something along the lines of: mv foo/bar/poit/zoid/narf.txt Suddenly I realized, damn, I have to type large parts of that parameter again: mv foo/bar/poit/zoid/narf.txt foo/bar/poit/zoid/troz.txt Even with tab completion, that's quite a pain. I know I can copy-paste the parameter by mouse-selecting the text and middleclicking but that is not good enough. I want to keep my hands on the keyboard. Is there a way to copy-paste the current parameter of the line using the keyboard?
