Selections are automatically shared with back-end servers. This provides seamless communication between back-end server clients and local clients. Some selections are not appropriate to share as they will cause unwanted conflicts. E.g. most manager selections. These selections can still be shared by adding a unique identifier to them. Selections that need this identifier can be specified using a command line option.
