1. Select only the elements you want to include in the file.
2. Use Ctrl+C (PC) or Command+C (Mac) to Copy the elements (or click on Copy from the Edit menu).3. Choose File>Save As, and set the file type to be Module File from Clipboard.
Note: There are two options for saving a module file. Be sure to choose Module File from Clipboard, not Module File.
