Detailed Description

The CmdHistory of a given target is the collection of all undoable and redoable steps that are currently available for this target. It hides single commands (ICommand) and command sequences (ICommandSequence). You can only access history steps, which are the undo/redo steps available via the undo/redo menu items. There is only one global CmdHistory. In order to use it you have to specify the target (ICommandMgr) you are interested in.
