If you are a long time "vi" user, put `set -o vi` in "~/.bashrc": the sequence to issue the previous command with sudo prepended will be <esc>0isudo<enter>, probably something that is in your muscle memory already.
While I'm a very long time vi user, and I'm completely at home with the keybindings, I could never get into using "set -o vi". For me it falls into the uncanny valley of being quite like vi while not actually being vi.
