This button is disabled if there is no previous value in the list. a button to retrieve the next value in that list (if there is one) This button is disabled if there is no next value in the list. a . a label to display the number of the item being displayed and the total number of items (e.g. "1/5") The initial output is as shown below 7k VowelsO prev >> next 1/5 Hitting thebon once (from the initial state above) produces the following output: 7% Vowels -D ??prev >> next 2/5 Hitting the">next" button three more times produces the following output: 74 VowelsD prev >> next 5/5
