C-RET in plain lists

[Renato <rennabh@gmail.com>]

Hello, just starting out with emacs org-mode (I'm going through the
compact guide). I'm wondering, is it possible to make C-RET
(org-insert-heading-respect-content) "work" also on plain lists?
i.e. make it insert a new list item of the same level *after* the
sub-list. 

what I'm trying to do is this: I have a such nested list

   - powers of 1:
	 1. 1
	 2. 1
	 3. 1
	 4. and so on
   - powers of 3:
	 1. 3
	 2. 9
	 3. 27
	 4. and so on

and I'd like to add a "powers of 2" entry in the middle... If C-RET
worked like in headings I could place the cursor on "powers of 1" and
do that, but it doesn't.


thanks for any help,
renato
