Yes, that's exactly what I mean. Actually, I often use keywords (e.g., =E2=80=98:group=E2=80=99, =E2=80=98:link=E2=80=99, and =E2=80=98:version=E2= =80=99) and symbols-for-boolean-values (such as 'noerror) in my Emacs Lisp code, but I have never combined them together. Thanks again for your info. --=20 Best regards, Xue Fuqiao. http://www.gnu.org/software/emacs/
