Useful Things for Your .emacs

If you want psd to be loaded automagically when you start up a Scheme session, put the expression

  (setq inferior-scheme-mode-hook 
        (cons '(lambda () (psd-mode 1))
              inferior-scheme-mode-hook))

in your .emacs file, or with Emacs 19, put instead

  (add-hook 'inferior-scheme-mode-hook 
            (function (lambda () (psd-mode 1))))

There is also a hook variable psd-mode-hook that you can use for customizing psd mode, for example to change key bindings.
