Re: Narrow: How to hide a specific part?

[daniel]

hi! that was an elisp programming answear, not an user answear!

But you can load this elisp and then use functions hide-region and
unhide-region


(defun hide-region ()
  (interactive)
  (setq ov (make-overlay (region-beginning) (region-end)))
  (overlay-put ov 'invisible t)
  (overlay-put ov 'my-overlay t)
  )

(defun unhide-region ()
  (interactive)
  (loop for ov in (overlays-in (region-beginning) (region-end))
if (overlay-get ov 'my-overlay)
 do (delete-overlay ov)
)
  )
