This is a good question. Please, can you write 2 lambda functions that
behaves exactly like the code below, and attach them to M-up , M-down ?
You should use only transpose-line, and none other function that deletes
text, like delete-and-extract-region, kill-line, etc.
(defun line-move-- (n)
(if (> (point-max) (point-at-eol))
(let ((column (current-column) )
(line (delete-and-extract-region (point-at-bol) (1+
(point-at-eol)))))
(forward-line n)
(insert-string line)
(backward-char)
(move-to-column column) ) ) )
(define-key global-map [(meta up)]
(lambda (&optional n)
(interactive "P")
(line-move-- (- (if (numberp n) n 1) ) ) ) )
(define-key global-map [(meta down)]
(lambda (&optional n)
(interactive "P")
(line-move-- (if (numberp n) n 1) ) ) )
;;;;;
Using transpose-line , it is much direct to simulate line-move--down than I
did.
