%u User defined specifier. The next character in the format string should

|
be a letter. Gnus will call the function gnus-user-format-function-X,
|
|
where X is the letter following %u. The function will be passed the

current header as argument. The function should return a string, which

will be inserted into the buffer just like information from any other

group specifier.

the mouse point move inside the area. There can only be one such area.

Note that this format specification is not always respected. For

|
reasons of efficiency, when listing killed groups, this specification

|
is ignored altogether. If the spec is changed considerably, your
|
|
output may end up looking strange when listing both alive and killed
|
|
groups.
|
|
|
|
If you use %o or %O, reading the active file will be slower and quite
|
|
a bit of extra memory will be used. %D will also worsen performance.

Also note that if you change the format specification to include any
|
|
of these specs, you must probably re-start Gnus to see them go into

effect."
