However, there are sometimes situations when you want to create components that are not available on the suggestion list. A good example is when you want to refer to a component that does not yet exist and you are going to create it soon. Another possibility is that Luna didn't get enough information to provide you with the complete components list, which could happen when you are working on polymorphic data. You will learn more about polymorphism later, for now just remember, that you can use the down arrow key to move the selection from the suggestions list onto the expression editor and press the enter key to create component named exactly what you have typed.
