There are various possibilities:

 centre_id   (then click on an atom)
 centre_zone molecule first_residue last_residue
 centre_atom molecule residue_name atom_name
 centre_xyz  x y z
 centre_next property operator value
 centre_previous property operator value

Examples of using the centre_next and centre_previous commands:

 centre_next atom_name = ca  (move to next residue)
 centre_next atom_name = o1  (move to next water)
 centre_next residue_rsfit < 0.6
 centre_prev residue_pepflip > 2.5
