How to do opposite of "join-with"?

[macintacos]

I used join-with to put two windows in the same container. I clicked on a link in one of those windows, and that created a new browser window that is now in that same container. I want to take it "out" of that container.

How exactly does one do that? I've read the docs for all of the commands and nothing seems quite right, so I'm hoping I'm just missing something obvious. Thanks in advance!

You can just move it, using one of your move <direction> binds, in the direction that you want to move it "out" of, placing it in the container in that direction (or creating a new one if one doesn't exist).
