In most spreadsheet-style programs, including Google Sheets and Libre Office Calc, if you select a set of cells and then use tab or shift-tab, you stay within that range of cells.
For example:
Create a sheet with 5 columns and 10 rows. Select A1 through C7. If you type shift-tab, you go from A1 to C7; shift-tab again and you’re in B7, then A7, then C6.
It would be really nice if selecting a range in Grist worked the same way.
Thanks!
