However I needed to modify the function a little. So now I have two working functions ; works (defun insert-lines (beg end) (interactive "r") (save-excursion (let ((line 1) (region-lines (count-lines beg end))) (goto-char beg) (while (< line region-lines) (end-of-line) (insert "\n") (forward-line) (setq line (+ line 1)))))) ; works (defun my-test (beg end) (interactive "r") (replace-regexp "\n" "\n\n" nil beg end)) and one which doesn't work (defun insert-empty-lines (beg end) (interactive "r") (goto-char beg) (while (re-search-forward "\n" end t) (replace-match "\n\n" nil nil))) namely if I select the following region from 1 (mark at 1) to 7 (mark after 7) 1 2 3 4 5 6 7 I get something like this 1 2 3 4 5 6 7 (note that there is no \n after 5 and 6). It seems that the replacement doesn't reach the end bound which was after number 7. Any ideas what is wrong? regards, -- Seweryn Kokot
