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