POS Menu Line
In the POS Menu Line table you can define properties for the menus you created in the POS Menu Header table.
In the table you can assign commands to menu keys, or if you are editing the fixed keys profile, you can assign a POS Command to keys on the POS terminal keyboard.
You can only assign functions to a certain amount of keys. If you are editing an on-screen menu for a touch screen,
there can only be 12 menu keys, and if the profile is not for a touch screen POS terminal,
there can usually only be 8 menu keys. Likewise, if you are editing a fixed keys profile,
you can only assign functions to the number of keys on the keyboard, and these must all have been assigned numbers in the POS Key Command table.
