How to move a subtree to another subtree in org-mode emacs

Question

I'd like to perform one simple task but there seems to be no clear solution for it:

I have a structure of subtrees like this:

* Tree A
** Subtree A1
** Subtree A2
* Tree B
** Subtree B1
** Subtree B2

I'd like to set up one key shortcut to move subtrees from Tree A to Tree B. Moving to the archive seems to be easy, but do you have any clue how to do it within one file?

Any help appreciated! Thanks!

Answer 1

You could try to refill the subtree with C-c C-w (it work also to move the subtree to another file).

Another way is to fold the subtree, then to kill it with C-k C-k and to paste it where it should be.

The third solution I use some time is to change the level of the subtree with M-left, then to move it with M-up and M-down, then M-right put it again on the correct level. This third way have the shortcoming that some time it make other part of the tree to move.
