Atom Modify
Change here the position of an atom (or list of atoms,
previously selected with Atom->Select, when Global is pressed),
in relative or absolute coordinates.
Parameters for empty entries or Local choices remain unchanged.
Translation
The coordinates of an atom can be changed
using the X, Y, Z entries.
Any values are accepted as good, even
if they are outside the range of visibility.
The change can be Absolute or Relative
(to the former position).
