 Link Properties
 
  The  keyring screen will be slightly different from the usual one, using a "chain link" icon to identify this key as one which is shared by a number of properties. Details of the key on the ring can be edited in the Keyring Details box, and in the Individual Keys box.
A warning will appear if you attempt to add a property which is already linked to this keyring.
Using the steps above, it is possible to create any combination of 
Master Key, 
Sub-set keys or 
key suites.  Please 
contact us if you would like to discuss your specific needs.
