189 %z A string that look like `<%s:%n>' if a foreign select method is used
190 %d The date the group was last entered.
191 %E Icon as defined by `gnus-group-icon-list'.
192 %F The disk space used by the articles fetched by both the cache and agent.
193 %u User defined specifier. The next character in the format string should
194 be a letter. Gnus will call the function gnus-user-format-function-X,
195 where X is the letter following %u. The function will be passed a
196 single dummy parameter as argument. The function should return a
197 string, which will be inserted into the buffer just like information
198 from any other group specifier.
200 Note that this format specification is not always respected. For
201 reasons of efficiency, when listing killed groups, this specification
202 is ignored altogether. If the spec is changed considerably, your
203 output may end up looking strange when listing both alive and killed
204 groups.
206 If you use %o or %O, reading the active file will be slower and quite
207 a bit of extra memory will be used. %D and %F will also worsen
208 performance. Also note that if you change the format specification to
209 include any of these specs, you must probably re-start Gnus to see
210 them go into effect.
212 General format specifiers can also be used.
