Need help identifying invisible button

Hello!

In my game, whenever I press Enter, I can hear the GUI click sound go off. However I for the love of God can’t find this button. Is there any event I could listen to or something that could help me identify this button? I have a lot of buttons in my application (it’s fairly complex).

Try:

render2d.ls()

This will show a list of all items attached to the 2D scene graph.
