Jump to top of next column on Enter

Hello,

I have an area where I'm entering data. It is 12 columns x 40 rows. I'd like to enter data in the left column, and when I hit "Enter" at the bottom of one column, I'd like the next cell selected to be at the top of the next column.

Example: The last cell in the first column is B49. When I hit "Enter", I'd like it to jump to C10 which is the top of the next column.

This maybe should be in programming, but I thought maybe there was a way to create a custom "work area" where the active cells are selected only in that range...

Thanks for any help.
