[plt-scheme] Re: Useful Emacs code when working with PLT Scheme

I use the following snipet. It reindent the whole sexp under the cursor.

  (defun indent-current-sexp ()
    (interactive)
    (save-excursion
      (unless (= (char-after) 40)
        (up-list)
        (backward-sexp))
      (indent-according-to-mode)
      (indent-sexp)))

  (add-hook 'scheme-mode-hook
    (lambda () (define-key scheme-mode-map "\C-\M-q" 'indent-current-sexp)))
