disable nodes in color page?

The ability to disable a color node seems to have disappeared or been moved in B15, anyone know where it's gone or how to disable anode in B15?

I just encountered a BUG in this area.
What Happened
+) COLOUR TAB : Face Refinement : Made changes to 'Eye retouching' : Eyebag removal.
+) Control/Command + D to disable a node : In order to compare before and after in FULL-SCREEN.
And then it just STOPPED working.
Clicking in the bottom left of the Node (on the number) STILL worked - but not Command + D.
I tried switching projects - which did NOT fix the problem.
Restarting the App DID fix the 'Control/Command + D' BUG.
