There are a couple other crucial ones that can still be done as optional key bindings, without imposing the restrictions of a structured editor:
(global-set-key [(meta left)] 'backward-sexp) (global-set-key [(meta right)] 'forward-sexp) (global-set-key [(meta backspace)] 'backward-kill-sexp) (global-set-key [(meta delete)] 'kill-sexp) (global-set-key [(meta up)] 'backward-up-list) (global-set-key [(meta down)] 'down-list) I blogged those 7 years ago, but only now decided to put them in Quack.
So they've been there for a while... These days I use paredit.el (in addition to Quack and Geiser) which does the sexp editing thing really well.
A more structured editor, like paredit.el or DivaScheme, seems like it should be the way to go for power-users, but I haven't spent enough time with them to get comfortable with them.
