Physical Code Editing

Is there any way to access the physical code in order to use code that I write? I thought there would be with the wixcode but can’t seem to find it. I would really like to be able to use code that I write in parts of the editor. Thanks!

Do you mean re-use?

You can copy the code appearing in the code panel at the bottom of each page. You can then paste into other page code panels - just make sure to connect event handlers to the appropriate components and adjust the component names as needed.
