- A listbox is used to select one or more of a list of strings. The
- strings are displayed in a scrolling box, with the selected string(s)
- marked in reverse video. A listbox can be single selection (if an item
- is selected, the previous selection is removed) or multiple selection

+ selected, the previous selection is removed) or multiple selection
(clicking an item toggles the item on or off independently of other
selections).
- List box elements are numbered from zero. Their number may be limited
