As in drag it? Not that I know of, I normally just zoom in really far. Also, as someone kindly pointed out to me here recently, top right of the timeline window there is a down arrow where you can select to show it in the audio units, which means you can make audio syncing more exact. I know it's not your question, just thought it was useful if you didn't know about it
Woooah! Thanks Miles and Will. That was really helpful :] Well, for some reason google doesn't help me these days in these more specific questions. Thanks again guys!
