Excel hotkey redesign. Remove 2003 compatibility.
The next Excel should feature a complete break from all legacy hotkeys and a complete hotkey redesign. The Excel Options menu should have an Excel 2016 compatibility checkbox that restores the legacy 2016 and 2003 hotkeys. This is similar to the Lotus compatibility settings.
On the ribbon, Alt-I should be insert, Alt-D should be Data, and Alt-V should be View. You didn't build it that way when you first introduced the ribbon because you tried to preserve Excel 2003 hotkeys. I thank you very much for this. However, the ribbon hotkeys make absolutely no sense. Who decided that Alt-JTA should rename a table? If you abandon Excel 2003 hotkeys, then it will be way easier to make sensible key combos for the ribbon. For example, renaming a table could be Alt (t)able,(n)ame. currently, you are constrained because Alt tn is reserved for compatibility.
