Numbers cell linked to formula?

[Ivar-1]

Hi, does anyone know how I can see if a cell in Numbers is linked to a formula in another cell. The other way around is obvious, but I would like cells to be highlighted or smth like that so I know that they're referenced to from another well (and I do not accidentally change them).
Thanks for any solution!

As far as I know, you can only double-click the cell to see the formula. If any value is taken from another sheet or table, it will be highlighted and shows with a name like SHEET::TABLE::CELL.
I am not aware how can one highlight all the cells that contain such formulas, if that's what you're looking for...
