sudo !!

I prefer tmux, but yes. Both do a great job in helping me manage my terminal sessions.

Another one of my favorite is ctrl+r to quickly search for a previous command.

Then type in a word from the command you are looking for and then hit tab to find the right command if there is more than one with that word.
