USER INTERFACE METHOD FOR MODIFYING A SELECTION LIST OF ITEMS TO ADD OR REMOVE ITEMS WHILE INDICATING ORIGINAL SELECTION

摘要

A user interface display method implemented on a computer-controlled device to allow an operator to define a list of selected items among a plurality of items available for selection. The operator starts by selecting a pre-existing list containing a number of selected items. A modified list is generated which initially contains the same items as the pre-existing list. The device displays all of the items available for selection, as well as first and second indications associated with each item initially in the modified list. Then, in response to operator inputs to add items to (or remove items from) the modified list, second indications are displayed (or removed from display) in association with the items to be added (or removed), without changing the display of any of the first indications and any of the plurality of items. The modified list is saved without changing the pre-existing list.
