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

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

145 have all the sub-threads as children.

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

387 particular, if the value is the symbol `quietly', the next unread
388 newsgroup will be selected without any confirmation, and if it is
