Navigating the command graphΒΆ
As noted previously, some objects require a selector to ensure that the correct object is selected, while other nodes provide a default object without a selector.
The table below shows what selectors are required for the diferent nodes and whether the selector is optional (i.e. if it can be omitted to select the default object).
