Preview toggle in Camera Raw version 13

In ACR vsersion 13 the eye icon at the top of each panel enables you to toggle adjustments for that panel on and off, but this doesn't seem to be available for the selective adjustment tools. In previous versions this was possible using the Default Toggle button at the lower right, which toggled the visibility of just the current adjustment tool, and in Lightroom there is an adjustment visibility switch for each of the selective adajustment tools. Can anyone tell me how I can do this in ACR 13.
