I figured out a way to get what I wanted.  A little bit of brute force with setfocus and the status of the list

xml:


<onclick condition="MusicPlayer.offset(0).Exists">SetFocus(9900,0,absolute)</onclick>

<onclick condition="MusicPlayer.offset(-1).Exists">SetFocus(9900,1,absolute)</onclick>



and so on to the last list item that may not exist. 

<onclick condition="MusicPlayer.offset(-10).Exists">SetFocus(9900,10,absolute)</onclick>
