If it's a short quote and replay, then I edit it in the box. If it's more than a paragraph or two, then I copy it into emacs, type a caret and hit escape-q and it does the whole paragraph. I then paste it back in.
I spend a lot of time in character-cell consoles and emacs mainly working in Unix environments.
