XmTranslateKey is the default XtKeyProc translation
procedure for Motif applications. The function takes a keycode
and modifiers and returns the corresponding keysym.
XmTranslateKey serves two main purposes: to enable new translators
with expanded functionality to get the default
Motif keycode-to-keysym translation in addition to whatever they add,
and to reinstall the default translator. This function enables
keysyms defined by the Motif virtual bindings to be used when an
application requires its own XtKeyProc to be installed.
