Perhaps if I explain WHY I asked this question, someone will lend a hand.

As it currently stands, mouseless keyboard access in KWord is severly hampered 
by the inability to position the caret inside text frames.  One way to 
provide that is to allow the user to edit frames from the document structure 
area panel on the left.  With the recent enhancements, it is now easy for a 
user to position focus to the doc structure area and invoke functions.  
However, when choosing the "Edit Text Frameset" option, KWord always 
positions the caret to the first frame of the frameset.  For example, if you 
have

Text Frameset 1
   Page 1
   Page 2
   Page 3

no matter which Page you highlight, when you choose Edit Text Frameset, the 
caret always goes to Page 1.  So what is needed is an "Edit Text Frame" 
option that goes to the first paragraph of the highlighted frame.  Hence my 
question.

I can probably do this by first invoking the "Select Text Frameset" option, 
then simulating a mouse click there, but that would be ugly.

I've studied the code and it appears that everything hinges on mouse clicks in 
the text area.  The KoRichText object takes care of positioning the caret 
where the mouse is clicked and code can then do things like

    KWTextFrameSetEdit* textEdit =
        dynamic_cast<KWTextFrameSetEdit 
*>(m_currentFrameSetEdit->currentTextEdit());
    KoTextCursor* cursor = textEdit->cursor();
    KoTextParag* parag = cursor->parag(0);

But this depends upon the caret being first positioned according to the mouse 
click.  I did notice there was some code when a caret exits to the left from 
a table that involved creating a temporary Anchor object.  Is this is a 
possibility?  I don't understand what anchors are.
