NAME
     XtSetKeyTranslator, XtTranslateKeycode,
     XtRegisterCaseConverter,  XtConvertCase - convert keysyms to
     keycodes

SYNOPSIS
     void XtSetKeyTranslator(display, proc)
     Display *display;
     XtKeyProc proc;

     void XtTranslateKeycode(display, keycode, modifiers,
     modifiers-return, keysym-return)
     Display *display;
     KeyCode keycode;
     Modifiers modifiers;
     Modifiers *modifiers-return;
     KeySym *keysym-return;

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

     void XtConvertCase(display, keysym, lower-return, upper-
     return)
     Display *display;
     KeySym keysym;
     KeySym *lower-return;
     KeySym *upper-return;

DESCRIPTION
     The XtSetKeyTranslator function sets the specified procedure
     as the current key translator.  The default translator is
     XtTranslateKey, an XtKeyProc that uses SHIFT and LOCK modif-
     iers with the interpretations defined by the core protocol.
     It is provided so that new translators can call it to get
     default keycode-to-keyboard-symbol translations and so that
     the default translator can be reinstalled.

     The XtTranslateKeycode function passes the specified argu-
     ments directly to the currently registered keycode-to-
     keyboard-symbol translator.

     The XtRegisterCaseConverter registers the specified case
     converter.  The start and stop arguments provide the in-
     clusive range of keyboard symbols for which this converter
     is to be called.  The new converter overrides any previous
     converters for keyboard symbols in that range.  No interface
     exists to remove converters; you need to register an identi-
     ty converter.  When a new converter is registered, the In-
     trinsics refreshes the keyboard state if necessary.  The de-

     fault converter understands case conversion for all keyboard
     symbols 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.

   Arguments
     These functions accept the following arguments:

     display Specifies the display.

     keycode Specifies the keycode to translate.

     keysym  Specifies the keyboard symbol to convert.

     keysym-return
             Returns the resulting keyboard symbol.

     lower-return
             Returns the lowercase equivalent of the keyboard
             symbol.

     upper-return
             Returns the uppercase equivalent of the keyboard
             symbol.

     modifiers
             Specifies the modifiers to the keycode.

     modifiers-return
             Returns a mask that indicates the modifiers actually
             used to generate the keyboard symbol.

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

     start   Specifies the first keyboard symbol for which this
             converter is valid.

     stop    Specifies the last keyboard symbol for which this
             converter is valid.
