How do you control seek bar in Windows media player?

[prabs]

I was making a remote using my gamepad.

I managed to configure it properly for GOM player and vlc media player but cannot control seek bar for windows media player.

I have set the analog stick right as ctrl,shift,f and left as ctrl,shift,b.

The right analog stick works as fastforward for song I tap button 3 (set as ctrl,p) twice to play the song properly at the point. It does not work for videos.

The left analog stick does not work at all.

Can anyone tell me the keyboard shortcuts for windows media player seekbar? I am using windows media player 10.

Thanks.
