+    // with different highlight ranges. The highlight ranges are set by the 
+    // preferredHighlightBegin and preferredHighlightEnd properties in ListView.
+    //
+    // The first ListView does not set a highlight range, so its currentItem
+    // can move freely within the visible area. If it moves outside the
+    // visible area, the view is automatically scrolled to keep the current
+    // item visible.
+    //
+    // The second ListView sets a highlight range which attempts to keep the
+    // current item within the the bounds of the range. However,
+    // items will not scroll beyond the beginning or end of the view,
+    // forcing the highlight to move outside the range at the ends.
+    //
+    // The third ListView sets the highlightRangeMode to StrictlyEnforceRange
+    // and sets a range smaller than the height of an item.  This
+    // forces the current item to change when the view is flicked,
+    // since the highlight is unable to move.
+    //
+    // All ListViews bind their currentIndex to the root.current property.
+    // The first ListView sets root.current whenever its currentIndex changes
+    // due to keyboard interaction.
+    // Flicking the third ListView with the mouse also changes root.current.
