The .FLAGS ALL and .NO FLAGS ALL commands function as master
    switches for all other .FLAGS/.NO FLAGS flag-name command
    settings, except the .FLAGS/.NO FLAGS COMMENT and .FLAGS/.NO
    FLAGS CONTROL commands.

    The .FLAGS ALL and .NO FLAGS ALL commands turn on and turn off
    recognition of all flags without disturbing other flag command
    settings. (An analogy for flag recognition is turning on a master
    switch [entering .FLAGS ALL] - those lights whose switches are
    in the ON position will go on and those whose switches are in the
    OFF position will not go on.) See also .ENABLE/.DISABLE BOLDING,
    HYPHENATION, INDEXING, OVERSTRIKING, and UNDERLINING commands.
