- Click on Template, select template from dropdown.
- Click customize - This puts the html code in the box below. If you want to save it to this area, click update at the bottom. Then it will stay in the customize box for you.
- Copy from the box into your html editor, make changes.
- Then paste back into the box and click update at the bottom.
Note: This doesn't change the original template which is in the dropdown (that is still as it was). So you can always go back to that template again if needed.
