+## KEYS_READY Frame {#frame-keys-ready}
+
+An endpoint sends a KEYS_READY frame (type=0x1e) to signal that it has installed
+keys for reading and writing packets.  Receipt of this frame in a packet
+indicates that all earlier keys can be safely discarded.

Note the receiving only is a hangup from before I added the bit about delaying transmission of the frame in order to limit the number of active keys.  If you don't have that, receipt is sufficient because receiving the frame always implies that you need to send a matching frame.
