How do I delete a grid?

[John Rodwell]

I have just started using appery.io as a complete novice. I have just dragged a grid into the frame as an experiment and now I want to delete it but I can't work out how to do it. There is no delete button. Can you help please? Also, is there a glossary of terms anywhere? The terminology and technical jargon is a real problem for a non-techie like me. E.g. I have no idea what 'Push' means etc!
May thanks
John
