■ PLU menu keys (categories)
Items can be categorized into PLU menu keys for ease of registration.
A PLU menu key can contain both PLU items and other PLU menu keys. This can make a PLU menu tree
of choices.
When the item (direct PLU) key is programmed within the PLU menu key, touch the corresponding PLU
menu key (main PLU menu key), then select the item (or sub-PLU menu key).
