XtSetKeyTranslator, XtTranslateKeycode, XtRegisterCaseConverter,
       XtConvertCase - convert KeySym to KeyCodes


       #include <X11/Intrinsic.h>

       void XtSetKeyTranslator(Display *display, XtKeyProc proc);

       void XtTranslateKeycode(Display *display, KeyCode keycode, Modifiers
              modifiers, Modifiers *modifiers_return, KeySym *keysym_return);

       void XtRegisterCaseConverter(Display *display, XtCaseProc proc, KeySym
              start, KeySym stop);

       void XtConvertCase(Display *display, KeySym keysym, KeySym
              *lower_return, KeySym *upper_return);


       display   Specifies the display.

       keycode   Specifies the KeyCode to translate.

       keysym    Specifies the KeySym to convert.

                 Returns the resulting KeySym.

                 Returns the lowercase equivalent of the KeySym.

                 Returns the uppercase equivalent of the KeySym.

       modifiers Specifies the modifiers to the KeyCode.

                 Returns a mask that indicates the modifiers actually used to
                 generate the KeySym.

       proc      Specifies the procedure that is to perform key translations
                 or conversions.

       start     Specifies the first KeySym for which this converter is valid.

       stop      Specifies the last KeySym for which this converter is valid.


       The XtSetKeyTranslator function sets the specified procedure as the
       current key translator.  The default translator is XtTranslateKey, an
       XtKeyProc that uses Shift and Lock modifiers with the interpretations
       defined by the core protocol.  It is provided so that new translators
       can call it to get default KeyCode-to-KeySym translations and so that
       the default translator can be reinstalled.

       The XtTranslateKeycode function passes the specified arguments directly
       to the currently registered KeyCode to KeySym translator.

       The XtRegisterCaseConverter registers the specified case converter.
       The start and stop arguments provide the inclusive range of KeySyms for
       which this converter is to be called.  The new converter overrides any
       previous converters for KeySyms in that range.  No interface exists to
       remove converters; you need to register an identity converter.  When a
       new converter is registered, the Intrinsics refreshes the keyboard
       state if necessary.  The default converter understands case conversion
       for all KeySyms defined in the core protocol.

       The XtConvertCase function calls the appropriate converter and returns
       the results.  A user-supplied XtKeyProc may need to use this function.
