Delete the selected tree from the database.
A tree may only be deleted if a protection level equal or higher (than the one assigned to the selected tree) has been chosen in the 'ARB_NTREE' main window.
Change the name of the selected tree. Tree names have to be unique.
Change tree comment
Each tree has a comment attached. The comment of each tree is displayed behind the trees name in the tree selection list.
The comment of the selected tree is displayed in the comment box. Simply modify the text there to change the comment.
Several functions that modify trees automatically append a note to the comment (e.g. copying or importing a tree).
Set protection level
The selection button above the tree comment box shows the protection level assigned to the currently selected tree. Change its value to assign a different protection level. See 'Delete' for effects.
Change order of trees
To change the order of the trees use the buttons at the right side of the tree selection list.
