 ``current-ao``
  Current audio output driver (name as used with ``--ao``).
 
+``clipboard`` (RW)
+ Access to the system clipboard as a key/value map of types and data.
+
+ Sub-paths can be accessed directly; e.g. ``clipboard/text`` can be read or written.
+
+ The top-level object itself can be written directly as a shortcut.
+
+ Converting this property to a string will give a JSON representation of all types.
+ Unset types will be null.
+
+ Currently, only the ``text`` type is available.
+
 ``user-data`` (RW)
  This is a recursive key/value map of arbitrary nodes shared between clients for
  general use (i.e. scripts, IPC clients, host applications, etc).
