5/10    I am using emacs to edit text file in the auto-fill or refill mode.
        It does not think tab = fixed number of spaces or fix column numbers
        but instead always take the first space of the last nonblank line as
        the tab position.  How to change that behavior?
        \_ M-x local-set-key <enter> <tab> self-insert-command <enter>
                -anonymous emacs user
        \_ M-x fundamental-mode
