Incremental tree constuction in a ctedit Window

[Guido.Bosch@loria.fr (Guido Bosch)]

I need to do some incremental tree construction with CENTAUR, i.e., I
want to develop trees starting at any operator that I defined in my
L.metal.

When I do syntactic editing in a new ctedit window, using the
"Beginner" or "Expert" facilities from the "Editing-Tools" menu, the
ctedit window always creats a top level starting node instance of my
language. I have no idea how Centaur guesses which is the best node to
put into the Ctedit (this is a new feature of Centaur 1.2, isn't it?),
but I would like to disable this and instead have the possibility to
choose it myself form the "Editor Ctmenu" window.

Is this feasable?
