You now need to replace the NoOp1 part of the expression with something—but
what? At the moment, Rectangle1 is sitting inside Group1. There's a hierarchy

23. Replace the word “NoOp1” with “parent” ( FIGURE 12.41 ) .
Figure 12.41. Calling for one level up in the hierarchy using the parent ex-

You need to change this for every other instance of an expression referencing the
NoOp1 node. In the next section, instead of doing it again manually, you use a
different method.

work with text editors that show you everything they put in the file
