Roman Key Card Blackwood
4NT once a suit has been agreed asks for the 5 key cards (trump K + aces):

5C: 0/3 key cards
5D: 1/4 key cards
5H: 2/5 key cards no trump Q
5S: 2/5 key cards with trump Q

Cue bids
These are a bit advanced, so we might not want to bother, but. Once a suit has been agreed explicitly or implicitly (e.g. 1NT-3S) and you're thinking about slam, bid of a side-suit shows first-round control of that suit, which might be a void. A return by either partner to the trump suit is often an end to the process
e.g. 1NT-3S-4D shows the first bidder to have 1st-round control in Diamonds (and no such control in clubs); you can continue on to 2nd-round controls if you like.
