Function lists are used for displaying additional functions that may have not been able to be allocated to the keyboard or to add short cuts and also quick operations.
For example, sell an item and in the item registration area, touch the item registered and a function list will appear. This function list allows you to use functions to interact with individually selected items.
Touch the ‘Table no.’ display area above the item registration area. This function list allows you to use functions to interact with all items e.g. subtotal discount.
