Hello!

I reworked the EnterKeyProcessingTest to try and match a similiar implementation that I have. I got a null pointer.

Thats besides the fact. With a basic scene and no layer widgets I was able to get the a delete to work. I used EnterKeyProcessingTest a base. But then I realized that the EnterKeyProcessingTest wasn't using layer widgets. So this is my attempt at reproducing my impl.
