Okay, that's the default behaviour. The example you are using now
deliberately suppresses that and does something else instead. Don't
work from that example.

Yes, that's the default KmlLayer behaviour with no special event
handling - the API displays <description> content for you on click
unless you instruct it not to.
> As these scripts would not work fully with my kml
Why do you think that? I think the simplest KmlLayer example in the
documentation should do you
