linking project and editors cursors

how can I unlink the project and lower zone cursors and zoom? I can’t find out in the manual, it says if you activate this feature but doesn’t say how. :blush:

In the lower zone, click the little gear icon in the upper right and make sure Auto-Scroll is checked. Then there should be an icon along the top of the lower zone that looks like a chain link. This icon controls whether the cursors (and zoom) in the project zone and lower zone are linked.
