Indicate how to remove a molecule (or list of molecules, previously         
selected with Molecule->Select, when 
Global is pressed).
Scope
When the 
Scope is 
All, the molecule and all 
its contents is removed. This is the default.
When the 
Scope is 
Container, the molecule is removed but
its contents (groups, planes, directions, atoms, bonds, orbitals, texts) 
is saved, linked to the cell parent. 
When the 
Scope is 
Contents, the cluster is preserved but 
all its contents (groups, planes, directions, atoms, bonds, orbitals, 
texts) is removed. 
When the 
Scope is 
group, 
plane, 
direction, 
atom, 
bond, 
orbital or 
text, these objects 
are removed from the cluster.
When the removed molecule included the current object,
the current layer becomes the new current object.
Clicking the mouse over a molecule in the current layer, its identification
is transported to the dialog and 
Ok is automatically pressed.
To recover the previous state press 
Undo.
