Accessibility Feature Request - Long line cursor (aka lotus 123 cursor)

Big sheets and lots of data. It would be nice to toggle a version of the cursor where as you navigate the bottom and Left or right borders of the row/column were either off color or bolded. 

This would assist the user in visually scanning across, up, or down to see totals or whatever is of interest.

I've seen vba kludges of this but this should be a native feature. For those that recall this was the standard nav in Lotus 123 (40 years ago) and is sorely missed as I get older.

In the example below it is easy to see the total at the right is 81,447.61

Please consider.

Thanks
