Touch on Small Receipt Expands to Full-Screen for Editing Individual

      A display is used to provide feedback to the clerk, verifying

the list is not something with which the clerk must regularly

more primary actions.  For the  most part, the clerk should not have

condition arises (ex. a price change must  be made) where the item

component on the display, thus, interfering with more primary aspects
of the task.
