Indicate how to remove an atom (or list of atoms, previously 
selected with Atom->Select, when 
Global is pressed).
Scope
When the 
Scope is 
All, the atom and all its contents 
is removed. This is the default. When an atom used to define an 
atomic plane or direction is removed, the plane or direction is 
automatically removed.
When the 
Scope is 
Container, the atom is removed but
its contents (orbitals, texts) is saved, linked to the atom parent.
Atom bonds are removed because they cannot live without the atom.
When the 
Scope is 
Contents, the atom is preserved 
but all its contents (bonds, orbitals, texts) is removed. 
When the 
Scope is 
Bond, 
Orbital or 
Text,
these objects are removed from the atom.
When the removed atom included the current object,
the current layer becomes the new current object.
Clicking the mouse over an atom in the current layer, its identification
is transported to the dialog and 
Ok is automatically pressed.
To recover the previous state press 
Undo.
