A view that displays a list of text items and allows one or more of them to be selected, depending on -selectionMode.
In default selection mode (single item selection), clicking on an item will select it, and pressing the up or down arrow keys will move selection to previous or next item, respectively. Other selection modes allow more complex interaction.
There is a difference between the concepts of current item, end selected items. In default selection mode they will always be the same, but not so in other modes.
