will still need the Tcl and Tk libraries.
One solution is to ship the application with the Tcl and Tk libraries, and point
-to them at run-time using the :envvar:`TCL_LIBRARY` and :envvar:`TK_LIBRARY`
+to them at run-time using the :envvar:`!TCL_LIBRARY` and :envvar:`!TK_LIBRARY`
environment variables.
To get truly stand-alone applications, the Tcl scripts that form the library
(https://tix.sourceforge.net/).
Build Tix with SAM enabled, perform the appropriate call to
-:c:func:`Tclsam_init`, etc. inside Python's
+:c:func:`!Tclsam_init`, etc. inside Python's
:file:`Modules/tkappinit.c`, and link with libtclsam and libtksam (you
might include the Tix libraries as well).
On platforms other than Windows, yes, and you don't even
need threads! But you'll have to restructure your I/O
-code a bit. Tk has the equivalent of Xt's :c:func:`XtAddInput()` call, which allows you
+code a bit. Tk has the equivalent of Xt's :c:func:`!XtAddInput` call, which allows you
to register a callback function which will be called from the Tk mainloop when
I/O is possible on a file descriptor. See :ref:`tkinter-file-handlers`.
I can't get key bindings to work in Tkinter: why?
-------------------------------------------------
-An often-heard complaint is that event handlers bound to events with the
-:meth:`bind` method don't get handled even when the appropriate key is pressed.

The most common cause is that the widget to which the binding applies doesn't
have "keyboard focus". Check out the Tk documentation for the focus command.
