Set it up like this:
|Preview player: Load|
|Preview player: Back (Increment: Normal)|
|Preview Player: Forward (Increment: Small)|

Now you can easily rest your left pinky on the | (Pipe) key for loading tracks into the preview player, left ring finger on 1 will skip back in the track and your midle finger and index finger will be on 2 key and 3 key for jumping forward.
Your thumb is resting on the space button and if you come across a track you like you simply add it to your preparation playlist.
Your right hand will controll the up and down buttons for the list and the thumb will also rest on the space button.
You'll save HOURS on doing it this way.
Alternativly clicking the S4 browse button down you will load the track into the preview player. Once playing you can rotate the knob for scanning through the track. Click the browse button again to stop the preview player playback.
