449 "*Non-nil means that the next newsgroup after the current will be on the same level.
450 When you type, for instance, `n' after reading the last article in the
451 current newsgroup, you will go to the next newsgroup. If this variable
452 is nil, the next newsgroup will be the next from the group
453 buffer.
454 If this variable is non-nil, Gnus will either put you in the
455 next newsgroup with the same level, or, if no such newsgroup is
456 available, the next newsgroup with the lowest possible level higher
457 than the current level.

466 scattered all over the summary buffer, Gnus can gather them.
468 If non-nil, Gnus will try to gather all loose sub-threads from an
469 original thread into one large thread.
471 If this variable is non-nil, it should be one of `none', `adopt',

536 If this variable is `ask-server', Gnus will ask the server for new
537 groups since the last time it checked. This means that the killed list
538 is no longer necessary, so you could set `gnus-save-killed-list' to
539 nil.
541 A variant is to have this variable be a list of select methods. Gnus
542 will then use the `ask-server' method on all these select methods to
543 query for new groups from all those servers.

563 parts of the active file from the server. Not all servers support
564 this, and it might be quite slow with other servers, but this should
565 generally be faster than both the t and nil value.
567 If you set this variable to nil or `some', you probably still want to
568 be told about new newsgroups that arrive. To do that, set
569 `gnus-check-new-newsgroups' to `ask-server'. This may not work

602 subscribed newsgroups, but not the rest, you'd set this variable to
603 `gnus-level-subscribed'.

1128 will be inserted into the buffer just like information from any other

1135 reasons of efficiency, when listing killed groups, this specification
1136 is ignored altogether. If the spec is changed considerably, your
1137 output may end up looking strange when listing both alive and killed
1138 groups.

1141 a bit of extra memory will be used. %D will also worsen performance.
