Off map boxes question

[jcrohio]

Today I was trying to get a better feel for where you can actually go when in an off map boxes. I looked at the Gold maps file named MapAreas.csv. Found a column titled "Jump Borders" and I think this is what I am looking for. Just to be sure, can someone help me as to exactly what the Jump Borders do. I have a pretty good idea but am not positive.

Thanks

Good question, it is confusing to me also. Is there a file somewhere with either a .jpg of the map, or a diagram of how all the boxes line up?
