This unique macro is specially designed to increase efficiency in the Fallout 4 game. It implements the function of duplicating objects. First you need to open the construction menu. Next, select the item you want to duplicate (note that it is only possible to disassemble the selected item before duplicating). Then, point the cursor at the selected item. At this point, just activate the button on your keyboard to which this macro is assigned. As soon as this happens, you will see that the amount of the selected item will double. Now you have the opportunity to increase your efficiency in the game through the possibility of duplicating items.
