You may find this function useful for that purpose:
;; Yeah!  We have indirect buffers!
(defun indirectize-buffer ()
  (interactive)
  (let* ((buf (make-indirect-buffer (current-buffer)
				    (generate-new-buffer-name "*indirect*")))
	 (extent (make-extent (point-min) (point-max) buf)))
    (put extent 'end-closed t)
    (set-extent-keymap extent (make-sparse-keymap))
    (define-key (extent-keymap extent) "\C-c\C-c" 'kill-this-buffer)
    (when (region-active-p)
      (narrow-to-region (region-beginning) (region-end) buf))
    (switch-to-buffer buf))
  (emacs-lisp-mode)
  (font-lock-mode 1))
(global-set-key "\C-ci" 'indirectize-buffer)
Mark the region and press `C-c i'.
