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."

109 If t, fetch all the available old headers."
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 "If non-nil referring a thread will limit the summary buffer to
124 articles in the thread. A nil value will add the thread articles
125 to the summary buffer."
131 "nil means that Gnus won't gather loose threads.
132 If the root of a thread has expired or been read in a previous
133 session, the information necessary to build a complete thread has been
134 lost. Instead of having many small sub-threads from this original thread
135 scattered all over the summary buffer, Gnus can gather them.
137 If non-nil, Gnus will try to gather all loose sub-threads from an
138 original thread into one large thread.
140 If this variable is non-nil, it should be one of `none', `adopt',
141 `dummy' or `empty'.
143 If this variable is `none', Gnus will not make a false root, but just
144 present the sub-threads after another.
145 If this variable is `dummy', Gnus will create a dummy root that will
146 have all the sub-threads as children.

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

206 If `some', only fill in the gaps that are needed to tie loose threads
207 together. If `more', fill in all leaf nodes that Gnus can find. If
208 non-nil and non-`some', fill in all gaps that Gnus manages to guess."

217 "Function used for gathering loose threads.
218 There are two pre-defined functions: `gnus-gather-threads-by-subject',

221 headers of the articles to find matches."

285 that will be removed from subject strings if fuzzy subject
286 simplification is selected."
291 "If non-nil, display threads in summary mode."
296 "If non-nil, hide all threads initially.
297 This can be a predicate specifier which says which threads to hide.
298 If threads are hidden, you have to run the command
299 `gnus-summary-show-thread' by hand or select an article."
309 "If non-nil, hide killed threads automatically."
314 "If non-nil, which is the default, ignore subjects and do all threading based on the Reference header.
315 If nil, articles that have different subjects from their parents will
316 start separate threads."
321 "If non-nil, subjects will be ignored when doing thread commands.

323 `gnus-summary-lower-thread'.
325 If this variable is nil, articles in the same thread with different

385 If the value is t and the next newsgroup is empty, Gnus will exit
386 summary mode and go back to group mode. If the value is neither nil
387 nor t, Gnus will select the following unread newsgroup. In
388 particular, if the value is the symbol `quietly', the next unread
389 newsgroup will be selected without any confirmation, and if it is
390 `almost-quietly', the next group will be selected without any
391 confirmation if you are located on the last article in the group.
392 Finally, if this variable is `slightly-quietly', the `\\<gnus-summary-mode-map>\\[gnus-summary-catchup-and-goto-next-group]' command

435 that have not been fetched), `always-undownloaded' (maneuvering always
436 ignores articles that have not been fetched), `unfetched' (maneuvering
