public interface CommandManager
extends SourcesCommandEvents

Interface for executing commands on a rich text area and for retrieving informations about the state of these commands. This is the recommended way of altering the document edited with the rich text area because others can be notified about these changes. A group of changes to the edited document, with a well defined purpose, should be grouped in a command.
