Article Selection commands:
n,SP Scan forward for next unread article.
N Go to next article.
^N Scan forward for next unread article with same subject.
p,P,^P Same as n,N,^N, only going backwards.
- Go to previously displayed article.
number Go to specified article.
range{,range} command{:command}
Apply one or more commands to one or more ranges of articles.
Ranges are of the form: number | number-number. You may use . for
the current article, and $ for the last article.
Valid commands are: j, m, M, s, S, and !.
/pattern/modifiers
Scan forward for article containing pattern in the subject line.
(Use ?pat? to scan backwards; append h to scan headers, a to scan
entire articles, r to scan read articles, c to make case sensitive.
/pattern/modifiers:command{:command}
Apply one or more commands to the set of articles matching pattern.
Use a K modifier to save entire command to the KILL file for this
newsgroup. Commands m and M, if first, imply an r modifier.
Valid commands are: j, m, M, s, S, and !.
f,F Submit a followup article (F = include this article).
r,R Reply through net mail (R = include this article).
s ... Save to file or pipe via sh.
S ... Save via preferred shell.
w,W Like s and S but save without the header.
| ... Same as s|...
C Cancel this article, if yours.
^R,v Restart article (v=verbose).
^X Restart article, rot13 mode.
c Catch up (mark all articles as read).
^B Back up one page.
^L Refresh the screen. You can get back to the pager with this.
X Refresh screen in rot13 mode.
^ Go to first unread article. Disables subject search mode.
$ Go to end of newsgroup. Disables subject search mode.
# Print last article number.
& Print current values of command-line switches.
&switch {switch}
Set or unset more switches.
j Junk this article (mark it read). Stays at end of article.
m Mark article as still unread.
M Mark article as still unread upon exiting newsgroup or Y command.
Y Yank back articles marked temporarily read via M.
k Mark current SUBJECT as read.
K Mark current SUBJECT as read, and save command in KILL file.
= List subjects of unread articles.
u Unsubscribe to this newsgroup.
^K Edit local KILL file (the one for this newsgroup).
q Quit this newsgroup for now.
