Nicole, I see you are quite enthusiastic and persistent in learning GH so I strongly suggest before you do anything else to sit and carefully read these guidelines for the forum:
You will learn a few things about GH itself and it will open the doors to getting help in this forum. A lot of people’s questions go unanswered because they don’t know how to make it easy for other users to help them.
Now, as far as your question goes, Just select everyting in one file (Ctrl+A and Ctrl+C) and then paste onto the other file (ctrl+v). (btw you can quickly change from one to the other with Ctrl+Tab)
Here, the green components have just been pasted into one of the files.
