+=item B<add> name
+
+Add a subkey named C<name> below the current node. The name may
+contain spaces and punctuation characters, and does not need to be
+quoted.
+
+The new key will have no subkeys and no values (see C<setval>).
+
+There must be no existing subkey called C<name>, or this command will
+fail. To replace an existing subkey, delete it first like this:
+
+ cd name
+ del
+
