KML + Google Earth: make polygon or GroundOverlay clickable?

Question

Pretty simple question.

I have several polygons and GroundOverlays defined in KML. Is there a way to indicate that they should be interactive, and (at least in Google Earth) an information ball or similar pops up when they are clicked?

In the same way, is it possible to give any polygons / GroundOverlays any manipulator behavior? For example, change the icon or color when fading?

. Google , . rollover/mouseover , , :

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
<Document>
<name>Highlighted Icon</name>
<description>Place your mouse over the icon to see it display the new
      icon</description>
<StyleMap id="exampleStyleMap">
  <Pair>
    <key>normal</key>
    <!-- you could also use a <styleUrl> here instead of inlining -->
    <Style>
      <PolyStyle>
        <color>7dff0000</color>
