[OpenLayers-Users] Browsing KML/Marker layer

[PPaFin]

Thanks,

This gives me zoom to all of KML points which I have loaded, which is 
needed also.

But what I want is that how do I select first loaded point in loaded KML 
file, zoom into it's location? After this, I would like to step trough 
and auto center every next item in loaded KML trail by pressing 'next' 
button on my webpage.

Goal of mine is to have this kind of GPS trail browser in my web page, 
but I am totally without a clue how to implement this ?

Ideas?
