Thank you for your post.
In FileMaker Pro 13, if you take a Text object and format the field under the Data tab of the Inspector as an Edit box, it will be listed under the Appearance tab Object type as "Field". If you go back to the Data tab and turn on "Include vertical scroll bar", when you return back to the Appearance tab, the Object type will then show "Field w/ vertical scroll bar".
In FileMaker Pro 14, this has changed to show "Scrolling Edit Box".
Let me know if you need additional clarification.
