 * `[ros2/rclcpp#715] <https://github.com/ros2/rclcpp/issues/715>`_ There is an inconsistency in the way that parameter YAML files are loaded between standalone ROS 2 nodes and composed ROS 2 nodes.
   Currently available workarounds are noted in an `issue comment <https://github.com/ros2/rclcpp/issues/715#issuecomment-497392626>`_
-* `[ros2/rclpy#360] <https://github.com/ros2/rclpy/issues/360>`_ rclpy nodes ignore ``ctrl-c`` when using OpenSplice on Windows.
+* `[ros2/rclpy#360] <https://github.com/ros2/rclpy/issues/360>`_ rclpy nodes ignore :kbd:`ctrl-c` when using OpenSplice on Windows.
 * `[ros2/rosidl_typesupport_opensplice#30] <https://github.com/ros2/rosidl_typesupport_opensplice/issues/30>`_ There is a bug preventing nesting a message inside of a service or action definition with the same name when using OpenSplice.
 * `[ros2/rclcpp#781] <https://github.com/ros2/rclcpp/pull/781>`_ Calling ``get_parameter``/``list_parameter`` from within ``on_set_parameter_callback`` causes a deadlock on Dashing.  This is fixed for Eloquent, but is an ABI break so has not been backported to Dashing.
 * `[ros2/rclcpp#912] <https://github.com/ros2/rclcpp/issues/912>`_ Inter-process communication forces a message copy when intra-process communication takes place between an ``std::unique_ptr`` publisher and a single ``std::unique_ptr`` subscription (published ``std::unique_ptr`` is internally being promoted to an ``std::shared_ptr``).
