XtGetActionKeysym - obtain corresponding keysym

event     Specifies the event pointer passed to the action procedure by the Intrinsics.

       modifiers_return
                 Returns the modifiers that caused the match, if non-NULL.

       If  XtGetActionKeysym  is  called after an action procedure has been invoked by the Intrinsics and before
       that action procedure returns, and if the event pointer has the same value as the event pointer passed to
       that action routine, and if the event is a KeyPress or KeyRelease event, then  XtGetActionKeysym  returns
       the  KeySym  that matched the final event specification in the translation table and, if modifiers_return
       is non-NULL, the modifier state actually used to generate this KeySym;  otherwise,  if  the  event  is  a
       KeyPress  or  KeyRelease  event, then XtGetActionKeysym calls XtTranslateKeycode and returns the results;
       else it returns NoSymbol and does not examine modifiers_return.
