@keyword COPPER USE
 
@english
 
The ''COPPER USE'' command is used to select and activate a specific copper list, 
replacing the currently running one. This command comes into play when you create 
multiple copper lists and want to switch between them.
 
@italian
 
Il comando ''COPPER USE'' serve a selezionare e attivare una specifica copper list, 
sostituendo quella che è attualmente in esecuzione. Il comando entra in gioco quando 
si creano diverse copper list, e si vuol passare da una all'altra.
