How To Get Authority Approvals For A Transaction?

[Sage]

Perhaps I'm missing something really simple, but I can't find anywhere how to get authority approvals for a transaction on a weighted account?

I have account_1 with a 2 weight.  I've added 2 accounts to it, both with a weight of 1, trying to get a 2 of 2 multi-sig.  So far so good.

Now, how do I actually send from account_1, with authority approvals?

UPDATE:
Figured it out.
