'Disconnecting' control surface sliders

If i connect a control surface slider to an ardour slider using Ctrl-MouseButton2-MoveControlSurfaceFader, how do i disconnect it without shutting down ardour and editing the connection out of the .ardour file?

Asked basically the same question before, but the last one was a little hard to read, so no-one’s answered it.


You do the same as you would to connect a fader to the slider, but click on the slider with the mouse in stead of moving a fader. Presto, you are disconnected!

i think its more reliable to click on the popup window, but i can’t check that from here.
