- The duplicate card (field grouping) dialog has a controller layout: the D-pad picks the original or new card, `A` continues and confirms the merge, `B` cancels or goes back from the preview, `X` turns "Delete duplicate" on or off, `Y` switches Compact / Full, and the D-pad scrolls the preview. Each control shows its shortcut, and the layout can be changed per controller in the new **Duplicate card (field grouping)** group of `Alt+C`.
