The following example shows what happens. Here, the node "get_observations" is selected and we will change a variable inherited from one of its parents, "0".

1. Here, the variable tree has been collapsed in order to show just the relevant parts. We've elected to modify the variable LAST_STEP. This is inherited from a node (0) higher in the hierarchy and does not exist locally in the selected node (get_observations). As the dialogue indicates, we will be modifying the get_observations node, not the 0 node | 2. A confirmation box explains that a new variable called LAST_STEP will be created for the get_observations task, and the original one, on node 0, will now be shadowed. | 3. The result is shown. LAST_STEP is now local to get_observations, and the version in node 0 is shadowed, i.e. not inherited by get_observations. |
