Navigating the command graph
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).

setups may wish to navigate via a
screen node to ensure that they
select the correct object.) |
