ARGUMENTS
display Specifies the display.
keycode Specifies the KeyCode to translate.
keysym Specifies the KeySym to convert.
keysymreturn
Returns the resulting KeySym.
lowerreturn
Returns the lowercase equivalent of the KeySym.
upperreturn
Returns the uppercase equivalent of the KeySym.
modifiers Specifies the modifiers to the KeyCode.
modifiersreturn
Returns a mask that indicates the modifiers actually used
to generate the KeySym.

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.
