Viewing the contents of the Standard is also called Stepping into a Level.
To view what is in a Standard you can:
-
Click the Level drop-down on the header then select Step In.
-
Use the Name fly out. You can also jump from one Standard to another from here.
When you step into a Standard, notice that the lines are yellow, because the parts come from a Custom Catalog. Also notice the title has changed to the name of the Standard in the header (Level bar).
