  When you release the encoder knob, the adjustment graph disappears,

  ==== Boolean Cue Variables
  
  If a cue has Boolean variables assigned to it, they will also appear
  above the effect name, with the current value showing as `Yes` or
  `No`. To adjust them you also start by grabbing the closest encoder,
  at which point you will see the two options with an arrow pointing at
