not sure if this would be called a feature or not, but when you're in the eq screen.... and you're in the middle right in the begining... you usually use the track fwd/back buttons to get to the bars...

if you use the volume while in the middle, and then use track fwd/back... it changes the track. in the rest of the player, any track fwd/back press while the volume bar is displayed only escapes the display.
