165 be a letter. Gnus will call the function gnus-user-format-function-X,
166 where X is the letter following %u. The function will be passed the
167 current header as argument. The function should return a string, which
168 will be inserted into the buffer just like information from any other
171 Text between %( and %) will be highlighted with `gnus-mouse-face' when
172 the mouse point move inside the area. There can only be one such area.
174 Note that this format specification is not always respected. For
175 reasons of efficiency, when listing killed groups, this specification
176 is ignored altogether. If the spec is changed considerably, your
177 output may end up looking strange when listing both alive and killed
180 If you use %o or %O, reading the active file will be slower and quite
181 a bit of extra memory will be used. %D will also worsen performance.
