To insert variable values into the “Data editor:”
Double-click on the cell of the table where you would like to insert a value. The values that have already been given to any of the cases in the column are in the drop-down list, sorted alphabetically. You can view this list and select a value from it by clicking on the triangle to the right of the cell you double-clicked on.
If the value isn’t available in the drop-down list, you can simply type in the value after double-clicking in the cell.
