On the left side, you find the sizable barcode list which is initially empty. Underneath you see three buttons:
A click on the Plus button opens the barcode types menu where you can choose from 31 barcode types. When you click on one of these barcode types, a new list entry will be added to your barcode list.
The Minus button is only selectable when at least one barcode is selected in the list above. The selected barcode(s) will be removed from the barcode list after a security alert.
A click on the Action button opens the Action menu which offers additional features which describe themselves.
