I don't use screensets and don't have it even showing in my control bar. Is there a keyboard shortcut I might have hit?
The number keys 1,2,3...,0 (not the numeric keypad but the top row of the main keys) are the shortcuts for Screensets 1-10.
I have found that using Screensets is a much better alternative to opening and closing individual views. Maybe you should consider it.
