I use org-metadown to swap two elements of a list in org mode, and I'd
like to swap any two org mode lines.

I've found this snippet: [Using M-up and M-down to transpose
paragraphs](https://orgmode.org/worg/org-hacks.html#orgcb907ce) :
however it moves the whole org-element (for example a paragraph), and
I want something simply line-based. I've tried to define this hook:

    (add-to-list 'org-metaup-hook
     (lambda () (interactive) (prog2 (transpose-lines 1) (previous-
line 2))))
    (add-to-list 'org-metadown-hook
     (lambda () (interactive) (progn (next-line 1) (transpose-lines
-1) (previous-line 1))))

But is doing strange things and I don't understand transpose-lines
very well. It seems like there is no way for the cursor move along
with the line you are moving up and down.

Is there a simpler way to do this?

Does (save-excursion) do anything?

Does transpose-lines, bound to C-x C-t do the job?

You can customize `org-metaup-hook`

Yes! I forgot about this, thanks

At the end the solution I've used is defining a new function and
assign the same keybindings as org-metaup:

     (defun org-metaup-universal ()

       (interactive)
       (condition-case nil
            (org-metaup)
            (user-error
                    (save-excursion (forward-line 1) (transpose-lines
-1)) (forward-line -1))))


Whenever `org-metaup` doesn't work because it's not on a list element
for example, it throws an `user-error` and fall backs to the function
that simply swaps two lines
