I really like the way I can move around the grid (change the selected cell) using the arrow keys. Now I am wondering why I can't move across bands using the arrow keys. When moving around I'm stuck within the grid I originally placed the selection. Can this be changed so I can move freely across all the bands/grids in the hierachy?
I do not think that this is supported out of the box currently. In theory, you could probably take advantage of the client-side object model (CSOM) of the grid and hook the KeyDown event

then using javascript, you can set focus to the first child band if you are on the last row of the parent grid... but it gets tricky, since you will need to hadnle up/down... the logic could be complex.

Thanks, I just went and made a feature request.
