+ on level one
+%R \"A\" if this article has been replied to, \" \"
+ otherwise (character)
+%U \"Read\" status of this article.

+%[ Opening bracket (character, \"[\" or \"<\")

+%> Spaces of length thread-level (string)

+%i Article score (number)
+%z Article zcore (character)
+%t Number of articles under the current thread (number).
+%e Whether the thread is empty or not (character).
+%V Total thread score (number).
+%P The line number (number).
+%O Download mark (character).
+%* If present, indicates desired cursor position
+ (instead of after first colon).
+%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
+ summary just like information from any other summary
+ specifier.
+&user-date; Age sensitive date format. Various date format is
+ defined in `gnus-user-date-format-alist'.
+
+
+The %U (status), %R (replied) and %z (zcore) specs have to be handled
+with care. For reasons of efficiency, Gnus will compute what column
+these characters will end up in, and \"hard-code\" that. This means that
+it is invalid to have these specs after a variable-length spec. Well,
+you might not be arrested, but your summary buffer will look strange,
+which is bad enough.
+
+The smart choice is to have these specs as far to the left as
+possible.
+
+This restriction may disappear in later versions of Gnus.
+
+General format specifiers can also be used.
