A bid of one of their shown suits is commonly called a cue bid – normally an ambiguous term, but in Chilli we use it solely to describe this rather than a high-level control show.
In neutral and fit auctions, cue bids have no special significance and mean whatever they would have meant had they not bid. In disturbed auctions, however, a cue bid at the first opportunity is always artificial.
A cue bid above 3NT is Exclusion Keycard Blackwood.
Below 3NT, a cue bid initially asks partner to bid no-trumps with a stop in the suit, but it may be the first move on a strong hand. In particular, this may be the only way to develop a good one-suited hand (GOSH) in some situations:

initially invited 3NT with a stop. Now that partner has pulled your response, it is clear that he has a GOSH. And although 4 is not forcing, it clearly directs you to consider a slam. Such a GOSH bid sets the suit and makes it a fit auction.| West | North | East | South | ||
