 Second, when using the ``PyOSInputHook`` approach, a GUI application should
 *not* start its event loop. Instead all of this is handled by the
 ``PyOSInputHook``. This means that applications that are meant to be used both
 in IPython and as standalone apps need to have special code to detects how the
-application is being run. We highly recommend using IPython's
-:func:`enable_foo` functions for this. Here is a simple example that shows the

-      from IPython.lib.inputhook import enable_wx

 Third, unlike previous versions of IPython, we no longer "hijack" (replace
 them with no-ops) the event loops. This is done to allow applications that
