59 "If non-nil, kill the summary buffer when you exit from it.
61 it will be killed sometime later."

74 "If non-nil, don't select the next message when using `SPC'."
81 "Non-nil means that Gnus will try to build threads by grabbing old headers.
82 If an unread article in the group refers to an older, already
83 read (or just marked as read) article, the old article will not
84 normally be displayed in the Summary buffer. If this variable is
85 t, Gnus will attempt to grab the headers to the old articles, and
86 thereby build complete threads. If it has the value `some', all
87 old headers will be fetched but only enough headers to connect
88 otherwise loose threads will be displayed. This variable can
89 also be a number. In that case, no more than that number of old
90 headers will be fetched. If it has the value `invisible', all
91 old headers will be fetched, but none will be displayed.
93 The server has to support NOV for any of this to work.
95 This feature can seriously impact performance it ignores all
96 locally cached header entries. Setting it to t for groups for a
97 server that doesn't expire articles (such as news.gmane.org),
98 leads to very slow summary generation."

115 "Use nnir to search an entire server when referring threads. A
116 nil value will only search for thread-related articles in the
117 current group."
123 "nil means that Gnus won't gather loose threads.
124 If the root of a thread has expired or been read in a previous
125 session, the information necessary to build a complete thread has been
126 lost. Instead of having many small sub-threads from this original thread
127 scattered all over the summary buffer, Gnus can gather them.
129 If non-nil, Gnus will try to gather all loose sub-threads from an
130 original thread into one large thread.
132 If this variable is non-nil, it should be one of `none', `adopt',
133 `dummy' or `empty'.
135 If this variable is `none', Gnus will not make a false root, but just
136 present the sub-threads after another.
137 If this variable is `dummy', Gnus will create a dummy root that will
138 have all the sub-threads as children.

143 given by the `gnus-summary-same-subject' variable.)"
152 "Always make a false dummy root."
158 "A regexp to match subjects to be excluded from loose thread gathering.
159 As loose thread gathering is done on subjects only, that means that
160 there can be many false gatherings performed. By rooting out certain
161 common subjects, gathering might become saner."
166 "Maximum length of subject comparisons when gathering loose threads.
167 Use nil to compare full subjects. Setting this variable to a low
168 number will help gather threads that have been corrupted by
169 newsreaders chopping off subject lines, but it might also mean that
170 unrelated articles that have subject that happen to begin with the
171 same few characters will be incorrectly gathered.
173 If this variable is `fuzzy', Gnus will use a fuzzy algorithm when
174 comparing subjects."
181 "List of functions taking a string argument that simplify subjects.
182 The functions are applied recursively.
184 Useful functions to put in this list include:
185 `gnus-simplify-subject-re', `gnus-simplify-subject-fuzzy',

197 "If non-nil, fill in the gaps in threads.
198 If `some', only fill in the gaps that are needed to tie loose threads
199 together. If `more', fill in all leaf nodes that Gnus can find. If
200 non-nil and non-`some', fill in all gaps that Gnus manages to guess."
208 'gnus-gather-threads-by-subject
209 "Function used for gathering loose threads.
210 There are two pre-defined functions: `gnus-gather-threads-by-subject',
211 which only takes Subjects into consideration; and
212 `gnus-gather-threads-by-references', which compared the References
213 headers of the articles to find matches."

277 that will be removed from subject strings if fuzzy subject
278 simplification is selected."
283 "If non-nil, display threads in summary mode."
288 "If non-nil, hide all threads initially.
289 This can be a predicate specifier which says which threads to hide.
290 If threads are hidden, you have to run the command
291 `gnus-summary-show-thread' by hand or select an article."
301 "If non-nil, hide killed threads automatically."
306 "If non-nil, which is the default, ignore subjects and do all threading based on the Reference header.
307 If nil, articles that have different subjects from their parents will
308 start separate threads."
313 "If non-nil, subjects will be ignored when doing thread commands.
314 This affects commands like `gnus-summary-kill-thread' and
315 `gnus-summary-lower-thread'.
317 If this variable is nil, articles in the same thread with different
318 subjects will not be included in the operation in question. If this

365 place point on some subject line."
376 "If non-nil, offer to go to the next group from the end of the previous.
377 If the value is t and the next newsgroup is empty, Gnus will exit
378 summary mode and go back to group mode. If the value is neither nil
379 nor t, Gnus will select the following unread newsgroup. In
380 particular, if the value is the symbol `quietly', the next unread
381 newsgroup will be selected without any confirmation, and if it is
382 `almost-quietly', the next group will be selected without any
383 confirmation if you are located on the last article in the group.
384 Finally, if this variable is `slightly-quietly', the `\\<gnus-summary-mode-map>\\[gnus-summary-catchup-and-goto-next-group]' command
385 will go to the next group without confirmation."

408 `next-noselect'
409 Move the cursor to the next article. This is the default.

413 If it has any other value or there is no next (unread) article, the
414 article selected before entering to the ephemeral group will appear."

425 This variable can either be the symbols nil (maneuver to any
426 article), `undownloaded' (maneuvering while unplugged ignores articles
427 that have not been fetched), `always-undownloaded' (maneuvering always
428 ignores articles that have not been fetched), `unfetched' (maneuvering
429 ignores articles whose headers have not been fetched).
