DivaScheme is an entirely unchorded set of key bindings for DrScheme,
including unchorded parens. It is based on a VI-style modal interface.

DivaScheme provide automatic templates for common Scheme forms,
which saves the typing of many parens. DivaScheme also has identifier
auto-completion, like Emacs' ALT-/ key.

I have severe RSI. DivaScheme boosts the amount of time I can spend
coding in Scheme from 30 seconds to about 5 minutes. I know it's
not much, but it's a world of difference to me.

DivaScheme can be hard to learn (it is VI-inspired, after all!). I am
the only fluid user (that I know of), and Danny Yoo is learning it. I
would love to hear your feedback, should you decide to try it.
