Well, I have the answer to my question now. Wide Fit doesn't exist for these commands. Using this xls file I got from Samsung support and the list of codes posted by JasonVP, we can now map out every existing command - and wide fit doesn't exist.

I hope this helps everyone in breaking down the Samsung commands. Samsung's support was so helpful in providing this file that I'm going to be very likely to purchase more of their products! Sorry, not trying to be a fanboy, it's just their customer service is great!
