**Reported by leonarddr on 2015-10-06 14:32** NVDA+shift+C/r set the start of column and row headers. However, when multiple cells are selected, NVDA doesn't react to these hotkeys. Steps to reproduce: 1. Open an Excel work sheet 2. Select multiple cells by moving to a1 and pressing shift+right arrow 3. Press nvda+shift+c or nvda+shift+r Expected: NVDA says "Set A1 through B1 as start of column/row headers" Actual: "C" or "R" is inserted in the first cell The only way to set multiple cells as the start of row/column headers is by merging them first and unmerging them afterwards. I can reproduce this in both Excel 2013 and 2016.
