Tracks do not have to start at time 0 but can be moved to an arbitrary starting time. To do so, just click on one of the small handles located at either end of the track (see the screenshot to the right) and drag it to the desired location. However, there always has to be at least one track starting at 0, so that the handles are greyed out if moving them would break this rule. It is also possible to move a track by hitting the [Option] key. This will turn the cursor into a little hand and allow to grab and drag the track.

The order of tracks can also be changed and tracks can even be moved from one document to another one. To do so, click into the shaded gray area located at the top of the track and drag the mouse to the desired location. This location can also be within a different document.
