須田さん、亀井さん、こんにちは。逸見 です。

須田さんのコードを改造してみました。
(provide "outline")
(in-package "editor")
(export '(outline outline-jump outline-margin *outline-pattern*))

(defvar *outline-pattern* "^[■◆◇●○・]")
(defun outline-margin () 20)

  (setq *outline-mode-map* (make-sparse-keymap))
  (define-key *outline-mode-map* #\F12 'outline-jump)
)

(defun outline-buffer-name (buf-or-string)
  (if (bufferp buf-or-string)
      (setq buf-or-string (buffer-name buf-or-string)))
  (concat "Outline-" buf-or-string))

(defun outline ()
  (interactive)
  (let ((sb (selected-buffer))
	ob obname)
    (setq obname (outline-buffer-name sb))
    (save-excursion
      (setq ob (get-buffer-create obname))
      (set-buffer ob)
      (setq buffer-read-only nil)
      (delete-region (point-min) (point-max))

        (while (scan-buffer *outline-pattern* :regexp t)
          (format t "~A~%"
            (buffer-substring (progn (goto-bol) (point))

    (goto-char (point-min))
    (scan-buffer string)
  )
)

(global-set-key #\C-F12 'outline)
