New heading in framework

["Barrie Fairley" <barfair () comcast ! net>]

Using one of the off-the-shelf framworks, I have a number of pages already
written in a manuscript.  I would now like to insert one or two new level
three headings at the beginning of certain paragraphs that are under the
same level two heading.  How do I do that?  Any time I try to insert a new
heading, its brackets appear at the bottom of the whole level two section.
When I try to maneuver them to the start of the desired paragraph, using the
yellow arrows on the toolbar, they will not go there.  I end up with a
frozen, messed up manuscript and have to back out without saving it.
