The list of cultures displays culture names, codes and short names. There are two action buttons placed on the left of every culture name, one for Editing () and one for Deleting () the Culture. You can also create a new culture by using the New Culture () button. You can use the filter above the list to limit which cultures are displayed using culture code, name or short name.
