A weird Apple word for the progress node of an audio or video track (the thingy you drag forward or backward to jump forward or backward).
There is also a "new" looking scrub bar for audio books and video podcasts in 3.0b. It has instructions that pop up on the screen when you press and hold on it. Very interesting.
Ya I heard about this, what does the scrub bar actually do? Just control the time in the podcast?
