I guess there are other uses than just ease of typing, but <Up> <Home> "sudo " <Enter> is as many key presses as "sudo !!" <Enter> (even fewer if one counts the <Shift> to get !), and more general. Similar combinations also nullifies other uses of the !! operator, in my experience. – Daniel Andersson Mar 26 at 15:10

Try:

!!:0- new_last_argument

See this article for an overview.

I couldn't tell from the article whether that was substituting or appending new_last_argument for old_last_argument. At the bottom of the link there's a cheat sheet that spells it out. Good reference! – quack quixote Oct 2 '09 at 14:15
