Add sibling?

[Doug Lerner]

If I want to add another level-one section what I usually do is:

1. Go to the previous section's level two.
2. Add Aunt.

If I want to add a child to a level-one row what I do is:

1. Go the row.
2. Add child.

But how do I add a "sibling" - a new level-one row if I am at "level  
one A":

level one A
	level two A
	level two A2
level one B
	level two B

What I want to add is "level one C" - a new section after level one B.

Both "Add child" and "Add row" seem to add a child, if I am at level  
one B.
