Misplaced Key Editor Controller Lanes - Cubase 8.5

I grossly mismanaged my mouse it seems and paid the price with all Controller Lane(s) in Key Editor now gone. Anyone know how to restore them (or it)? I can create a new project and import all my tracks into it, but there must be a better way.



Down in the Key Editor on the Left side, click to the + button, or to the “paper” button to show the Controller Lane back.
