Skipping to next song with the TP2 ? (when screen's off)

[BustedNuts1]

I was thinking about getting a TP2, but am curious as to how you guys skip to the next track when listening to albums or playlists (when the screen's turned off). On my TP I have them mapped to the dpad keys, but since you guys have no dpad, how do you do it?

(I do not want to use a bluetooth headset and a media player with AVRCP. I'd like to plug in normal headphones via a 3.5mm adapter, or even use the earbud headphones that come with HTC's products.)
