Link Project and Lower Zone Cursors

I am trying to make the keyboard shortcuts to toggle between cursors the same for lower piano roll and the upper window. I see there is a button labeled “Link Project and Lower Zone Cursors.” However, when I press this, the keyboard shortcuts do not change the cursors in both windows. Is this button suppose to achieve this? If so, is there something else I need to do? If not, is there another way to achieve this?
