        (All articles are marked as read.)

m       Mark or unmark article for reading or a later command.
M       Toggle mark on following articles with same subject.
        (This is the same as typing 'm' on each of them.)
X       Junk (mark as read) all unmarked articles.
D       Junk unmarked articles on the same page. (similar to 'X')
        ['X' and 'D' act like the TRN thread selector options.]
J       Junk marked articles on page.  (opposite of 'D')

e       Extract marked articles (in shar, ship, or uuencoded format) to a
        directory, and/or continue an incomplete file extraction.
        Multipart uuencoded files must be extracted in the proper part
        order--strn does not check for misordered parts.  If the parts of
        a uuencoded file are out of order then the 'e'xtract command should
        be used multiple times to extract the parts in order.
E       End/Examine the last extracted file.  A command can be entered to
        examine/view/play the extracted file.  If the file was incomplete,
        it can be removed.

S       Select (for zoom) all following articles with same subject.
z       Enter/exit "zoom" mode--only selected articles are displayed.
        (Zoom mode is automatically entered when article-scan mode is
        entered from the TRN thread selector.)
Z       Clear (Zero) the zoom selections
        [Note: when in zoom mode commands which delete articles will
        only delete selected articles.  This means, for instance, that
        'X' will only delete *selected* unmarked articles.  (Useful for
        reading only a few articles from a thread.)]

+       Enter thread selection mode (only if group is threaded).
!cmd    Escape to a subshell and execute cmd.
&       Print current values of command-line switches.
&switch {switch}
        Set or unset more switches.
&&      Print current macro definitions.

q       Quit reading this newsgroup and go to the next one.
Q       Leave article scan mode and begin reading articles, starting
        with the article pointed to.  You will not return to
        article-scan mode unless you type ';' again.

/text   Search article descriptions forwards for text.
?text   Search article descriptions backwards for text.
gtext   Search newsgroup/topic descriptions forwards for text.  If no
        matching descriptions are found, continue the search from the
        first newsgroup/topic description. (wrap-around search)
        Searches are for case-insensitive substring of article
        descriptions matching text.  Leading spaces in text are ignored
        (which means you can type "g John Smith" or "gJohn Smith")

f       Toggle subject following mode.  When enabled article threads
        will be followed normally.  When disabled typing space or
        return at end of article will return to article-scan mode.
        Typing a command explicitly (like ^n) will still work.
        (If an explicit command is typed, follow mode will be temporarily
        turned on for the remainder of the thread.)
F       Toggle subject Folding mode.  (show only first article with a
        subject.  Note that "first" depends on ordering...)
z       Zoom toggle (show only "selected" articles in zoom mode.  Zoom
        mode is automatically entered when article-scan mode is entered
        from the TRN thread selector.)
U       Toggle reading eligibility: read / unread+read
TAB     Toggle display of "threadcount" (# of articles following this one
        with the same subject)
a       Toggle display of authors.
#       Toggle display of article numbers.

o       Toggle article ordering: arrival or score-sorted.
O       Toggle article ordering between older-first and newer-first
        when in score-sorted order.  (For two articles with same
        score, toggle between the older one first or the newer one first.)

'e <abbreviation OR filename>
        Edits the scorefile named by the following file abbreviation
        character or full filename.  If no arguments are given, edits the
        local scorefile (the one for the current newsgroup).

Virtual newsgroup commands:
V       Virtual group command prefix.

V+<filename> <text>
        Adds <text> to <filename>.  The <filename> must start with 
        '~', '%', or '/'.
        The <text> may also be one of the following abbreviations:
        "M", "I", or "A".  These abbreviations place a group command
        followed by a '+' command for the current article.
        The "M" and "I" abbreviations use the article's message-id.
        The "A" abbreviation uses the article number of the message.
        (The abbreviations will prompt for an alternative subject.)
