Problem description: 

If you drag a chapter inside the Navigator with the mouse to another position and at the same time press the Ctrl button, a “+” is displayed at the mouse pointer. It suggests that a copy of the chapter is performed. But only a move is performed. 

In order to reproduce, do this:

(1) Open a new text document and insert three headings.
(2) Display the Navigator and display only headings in the Navigator.
(3) Press the Control button and drag one of the headings inside the Navigator with the mouse to another position. The “+” is displayed at the mouse pointer !!!

This is only an unimportant flaw, but it would be nice, if not only a move is possible but also a copy of chapters with the Navigator. Such a function makes sense if you like to create several similar chapters and you want to use one of these chapters as a template for new chapters.
Operating System: Windows 7
