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)

ARGUMENTS
display Specifies the display.
keycode Specifies the KeyCode to translate.
keysym Specifies the KeySym to convert.
keysym_return
Returns the resulting KeySym.
lower_return
Returns the lowercase equivalent of the
KeySym.
upper_return
Returns the uppercase equivalent of the
KeySym.
modifiers Specifies the modifiers to the KeyCode.

modifiers_return
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.
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 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.
