I can't see which cell I am on...

[M Skabialka]

If I am working in a spreadsheet with multiple colors, as I move from cell
to cell the border is highlighted a contrasting color, e.g the border on a
turquise cell is red. This makes it easy to see which cell I am on.

But I have another spreadsheet with no background color and black text, with
many of the cells with a black border. When I am on one of those cells the
border shows as black, but you really can't tell which cell you are on
amongst all of the others outlined in black. Is there a way to use a more
vivid contrasting color, such as red, to highlight the border of the cell
you are on if it is a white cell with black contents?

Thanks,
