(defun open-line-a-la-vi ()
    (interactive)
    (forward-line)
    (open-line (or prefix-arg 1)))
(global-set-key "\C-o" 'open-line-a-la-vi)

See functions  up-list, forward-list, backward-list.   The terminology
is lisp, but  they work correcly in other  syntaxes too.  For example,
beginning-of-defun moves to  the beginning of the function  in C mode,
where there is no defun like in lisp.

You can attach them or a combination of the to a key  like above.
