Delete
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 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).
