+%N Article number, left padded with spaces (string)

+%x Contents of the Xref: header (string)
+%D Date of the article (string)
+%d Date of the article (string) in DD-MMM format
+%M Message-id of the article (string)
+%r References of the article (string)
+%c Number of characters in the article (integer)
+%L Number of lines in the article (integer)
+%I Indentation based on thread level (a string of spaces)
+%T A string with two possible values: 80 spaces if the article
+ is on thread level two or larger and 0 spaces on level one
+%R \"A\" if this article has been replied to, \" \" otherwise (character)
+%U Status of this article (character, \"R\", \"K\", \"-\" or \" \")
+%[ Opening bracket (character, \"[\" or \"<\")
+%] Closing bracket (character, \"]\" or \">\")
+%> Spaces of length thread-level (string)
+%< Spaces of length (- 20 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).
+%l GroupLens score (string).
+%V Total thread score (number).
+%P The line number (number).
+%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.
+
+Text between %( and %) will be highlighted with `gnus-mouse-face'
+when the mouse point is placed inside the area. There can only be one
+such area.
+
+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 illegal 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 for to the left as
+possible.
+
+This restriction may disappear in later versions of Gnus."
