ListView should provide convenience methods for setting the selection mode and selected index, like JList does in Swing. Among other things, this would make it easier to work with ListViews in FXML:

<ListView multiSelect="true" selectedIndex="0"/>

For comparison, the list view controls in other common UI toolkits provide similar properties:

Flex:
<s:List allowMultipleSelection="true" selectedIndex="0"/>

WPF:
<ListBox SelectionMode="Multiple" SelectedIndex="0">

HTML:
<select id="mySelect" multiple="multiple">

<script>
document.getElementById("mySelect").selectedIndex = 0;
</script>

These properties should probably be mirrored in TableView as well, and ChoiceBox should probably support the "selectedIndex" property.
