 This glossary defines terms and names commonly used throughout the Native Client
 documentation.
 
 asynchronous programming
   In the asynchronous programming model, function calls are executed and return
   immediately without waiting for a response. Using this model, function calls
   are non-blocking; the web browser continues its main thread of execution
   and gets notified of asynchronous call completion through callbacks or some
   other mechanism.
 focus events
   Events that indicate whether certain parts of a web page are
   in or out of focus.
 input events
   Events that occur when an input device (such as keyboard or mouse)
   is used to interact with an module instance.
 instance
   A rectangle on a web page that is managed by a Native Client module (the
   rectangle can have ``width=0`` and ``height=0``, which means that nothing is
   drawn on the page).
 manifest file
   A file containing metadata or information about accompanying files.
 message events
   Events used to pass data between JavaScript and the Native Client
-  module (see the :doc:`Messaging System <devguide/coding/message-system>` chapter).
+  module (see the :doc:`Messaging System <devguide/coding/message-system>` section).
 module
   Depending on context, "module" may mean one of two things. First, it may be a
   general short-term for for "Native Client module"---compiled C/C++ code
   produced with a Native Client toolchain (for example PNaCl). See
   :ref:`link_how_nacl_works` for more details.
   Second, it may refer to a concrete implementation of the `pp::Module class
   </native-client/pepper_stable/cpp/classpp_1_1_module>`_ for some Native
   Client module.
 progress events
   Events generated by the Native Client runtime system during the
   module loading process.
 Var
   An object in a Native Client module that corresponds to a JavaScript
   variable.
 view change events
   Events that occur when a change in the browser affects the
   module instance (such as resizing the browser window or going to
   and from fullscreen mode).
 web workers
   `Web workers <http://en.wikipedia.org/wiki/Web_Workers>`_ provide a
   mechanism for running heavy-weight JavaScript code on background threads
   so that the main web page can continue to respond to user interaction.
   Web pages interact with web workers by using ``postMessage()`` to send
   messages. The way a web page interacts with a Native Client module
   is analogous to the way it interacts with web workers.
