    I'm having trouble getting accelerators to work.  What's wrong with
    the following code?  The intent is to have a Return keypress in the
    dialog's `value' widget cause a set()notify()unset() action sequence
    in the dialog's `show' widget.  I'm using the R3 Athena widgets on a
    DS 3100 running Ultrix.
    
    Thanks for any help - John

        acc = XtParseAcceleratorTable("<Key>Return:set()notify()unset()");
        XtSetArg(arg[0], XtNaccelerators, (XtArgVal) acc);
        XtSetValues(cmd, arg, 1);
        XtInstallAccelerators(val, cmd);
        XtRealizeWidget(top);
        XtAppMainLoop(ac);
    }
    ----------

The problem seems to be the merge mode used.
XtInstallAccellerators will merge the accelerators using
augment semantics unless there is an explicit "#override"
directive in the accelerators string. Try:
    
    
acc = XtParseAcceleratorTable("#override <Key>Return:set()notify()unset()");
