Schema map & relationships — Name the connection

The link's Key is its connection name — the label RowFold groups links by. The optional Label is a human-friendly note shown alongside the connection. • A Key that matches a Relation field on the starting record's table is rejected — you'll be told to set that field on the record instead, which keeps the one-off link from being wiped the next time the record saves. • Creating an identical link twice (same two records, same Key) quietly does nothing; no duplicate is stored.
