+listkeys
+--------
+
+List values in a specified ``pushkey`` namespace.
+
+The command receives the following arguments:
+
+namespace
+   (bytestring) Pushkey namespace to query.
+
+The response is a map with bytestring keys and values.
+
+TODO consider using binary to represent nodes in certain pushkey namespaces.
