The entities are not directly selected, but they can be accessed through selected claims. A call creates a list of current selected claims by using their containing entities. This can happen implicit or be made explicit. Implicit selections are created from the connected entity (could be better to use a dot-keyword), but also after after each fetch operation. Explicit selections are made by inserting parenthesis, and those copy the current selection unless given an explicit selection by listing their containing entities after the opening parenthesis.
