To find the identifiers of operations and manipulators you wish to unregister, create
an instance of the tool with the items still registered, and use the FindIdentifiers
method of the IDLitTool class to retrieve the full identifiers of the items you are
interested in. See “Retrieving Component Identifiers” on page 382 for details.
