I was looking at somebody's Excel worksheet and they had included a little
cell format that I've never seen before and can't figure out how to
replicate.  They had formatted a cell so that the bottom-left corner of the
cell was red.  This little feature looked a lot like Excel's own comment
indicator that appears in the top-right corner of the cell.

This feature didn't prevent the cell from containing and displaying it value
(again like a comment indicator).

I can't figure out how to achieve this effect from Excel's user interface
much less using Control's object model.

Anybody know how to do this?

TIA,
