Abstract: A change propagation command, in one embodiment, causes the creation of induced commands in order to propagate commands in a collaborative document creation process that involves at least two client systems and a server system. The change propagation command received on a client system causes the creation of induced commands to a local copy on that client system and also causes the creation of induced commands on the server system. The induced commands in one embodiment apply changes to any objects that were added after the original change propagation command was received.
