avoiding "First item of list cannot move without its subtree"

avoiding "First item of list cannot move without its subtree"

Hi,

First time poster and recently started using org-mode and so far 
enjoying it :)

One nag I do have though is how moving of basic lists are handled.
I constantly bump into "First item of list cannot move without its 
subtree"

Is there a way to avoid this error and instead be given the option to 
say "Please just move it up to the next level" ?

What I often have is that I during a meeting or brain dump do this:

```
* Some important topic
   - idea 1, some notes
   - idea 2, another note
   - idea 3, a third note
```

And then I go over these and I use the shift/alt+keys to reorder the 
ideas up and down and eventually I would like to do this:

```
* Some important topic
   - idea 1, some notes
   ** TODO idea 2, another note
   - idea 3, a third note
```

I know I can press a short cut to make it a top item, but why can't I 
just use the normal standard tree editing keys ?

Is there a way to have org-mode ask what kind of thing it should do when 
I move the lists "out-of-bounds" instead
of just error out on me ?

Thank you,

OK.

What is that? Is "** TODO idea 2, another note" a headline, in which
case it should be at column 0?

Headlines are different from plain lists. You can use C-c * on second
item to turn it into a headline.

You can also move to the beginning of line (C-a), kill word (M-d) and
insert the two stars. It is a longer but maybe more natural, since those
are standard text editing keys.

I'm not sure to understand what "standard tree editing keys" you're
talking about.

AFAIU, you want to turn a structure (a list) into another one (a
headline). There's a command for that, but I don't consider the action
to be a standard editing one.

IMO, you may be mis-using the tool.

Yes sorry, bad indent.

Yes, I know about that one - but I would prefer not having to change to
another set of keys :)

I can do shift arrow left/rigt/up/down for the list item *until* I hit 
the top heading.

this is what I do know - just more tedious if shift + arrows could ask 
instead of blocking.

shift arrows up/down/left/righit.

Yes, but it would be so convenient it would not just block edit and 
require
shifting to completely different keys IMO.

Might be - but seems it fits very naturally to be able to at least allow 
to move list items outside its parent.

Don't get me wrong - I  like it defaults to stopping, but would prefer 
it would ask or let me do shift + left + left to override or something 
similar.

IMO, the current behaviour is the right one.

However, you can advice, e.g., `org-shiftmetaleft' so it catches the
error and calls `org-ctrl-c-star' instead.

Any pointers on how to do this ?

I tried this but no luck to get hooked in:

```
(defadvice org-fix-list-indent
    (around org-list-indent-item-generic)
  "Advise list indention to trigger creation of star instead"
  (message "DO MAGIC!")
  (ad-do-it)
)
```

But with this "DO MAGIC!" does not show up.

The function to advice is `org-shiftmetaleft', not
`org-fix-list-indent'.

Anyway, you can also add something like the following to
`org-shiftmetaleft-hook':

  (defun my-shiftmetaleft ()
    (interactive)
    (let* ((element (org-element-at-point))
           (list-parent (org-element-lineage element '(item plain-list) t)))
      (when (and list-parent
                 (= (line-beginning-position)
                    (org-element-property :post-affiliated element)))
        (call-interactively
         (if (org-element-lineage list-parent '(item)) ;not at top level
             #'org-outdent-item-tree
           #'org-ctrl-c-star))
        t)))

Thanks! I did this but still no effect ;/

What am I doing wrong ?

```
(add-hook 'org-shiftmetaleft-hook
	  (lambda ()
	    (interactive)
	    (let* ((element (org-element-at-point))
		   (list-parent (org-element-lineage element '(item plain-list) t)))
	      (when (and list-parent
			 (= (line-beginning-position)
			    (org-element-property :post-affiliated element)))
		(call-interactively
		 (if (org-element-lineage list-parent '(item)) ;not at top level
		     #'org-outdent-item-tree
		   #'org-ctrl-c-star))
		t))))

Nothing. There is a typo in my code.

Fixed the typo - but still nothing happens :/

"Nothing happens" is a bit vague. M-S-Left should demote an item. When
it reaches top-level, it should be turned into a headline. What happens
instead?

The same as before, i.e. I observe no difference.

Here is a screencast of me trying before and after evaluating buffer 
with the function in it.

Odd. I definitely see TRT in my case. 

What is the value of `org-shiftmetaleft-hook' ? Could you try in
a minimal environment to check if nothing interferes with the function
(e.g., `org-autolist')? 

If that fails, could you debug `my-shiftmetaleft' and see if it is
called at all?

Gah - my brain was wired wrong. I tried to use meta-left, not shift-meta-left.

Now it is working - thanks :)

Maybe change your approach and use headlines throughout:

* Some important topic
** idea 1
some notes
** idea 2
another note
** idea 3
a third note

?

You can still move these about and pro/de-mote them as required but you
can now add task management keywords easily.

I did it this way until I learned about basic lists.

I prefer basic lists because they visually default to be much less 
prominent highlighted.

Thus I prefer the lighter approach by default and only make thins into 
headings when needed.
