Joining sectors GZDoom/Doom Builder

[UgiBugi]

How do I "join" two sectors in Doom Builder?

And by "joining" I mean that two sectors that don't share any linedef or vertex behave as one sector, which means they have the same height, floor/ceiling textures and brightness.
Basically the reverse of the "Make sectors" tool in Doom Builder.

IIRC, just select both and press J.

In addition, if you want to join sectors that do share lines you can press Shift-J to join the sectors and remove their shared lines.

Yep. Thanks!

If the sectors you are joining have any lines in common, J (Join) will leave them there and Shift-J (Merge) will remove them, I think. I always get those confused. If I got it backwards, that's what Control-Z (Undo) is for. Each is useful in certain circumstances.
