Slade - Unjoin or Make Sectors

[bumcheekcity]

Quick request for help - in Doom Builder 2, there's a "Make Sector" option which will easily break out things like the below into three separate sectors. I can't find a unjoin / make sector option in SLADE - does one exist, and how do I use it if it does?

Just hit the "create sector" key (<insert> by default, when in sector mode) while the mouse cursor is in one of the sectors you want to detach.

Thankyou! I knew it would be simple!
