2697 %r References of the article (string)
2698 %c Number of characters in the article (integer)
2699 %k Pretty-printed version of the above (string)
2700 For example, \"1.2k\" or \"0.4M\".
2701 %L Number of lines in the article (integer)
2702 %I Indentation based on thread level (a string of spaces)
2703 %B A complex trn-style thread tree (string)
2704 The variables `gnus-sum-thread-*' can be used for customization.
2705 %T A string with two possible values: 80 spaces if the article
2706 is on thread level two or larger and 0 spaces on level one
2707 %R \"A\" if this article has been replied to, \" \" otherwise (character)
2708 %U Status of this article (character, \"R\", \"K\", \"-\" or \" \")
2709 %[ Opening bracket (character, \"[\" or \"<\")
2710 %] Closing bracket (character, \"]\" or \">\")
2711 %> Spaces of length thread-level (string)
2712 %< Spaces of length (- 20 thread-level) (string)
2713 %i Article score (number)
2714 %z Article zcore (character)
2715 %t Number of articles under the current thread (number).
2716 %e Whether the thread is empty or not (character).
2717 %l GroupLens score (string).
2718 %V Total thread score (number).
2719 %P The line number (number).
2720 %O Download mark (character).
2721 %* If present, indicates desired cursor position
2722 (instead of after first colon).
2723 %u User defined specifier. The next character in the format string should
2724 be a letter. Gnus will call the function gnus-user-format-function-X,
2725 where X is the letter following %u. The function will be passed the
2726 current header as argument. The function should return a string, which
2727 will be inserted into the summary just like information from any other
2730 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2731 with care. For reasons of efficiency, Gnus will compute what column
2732 these characters will end up in, and \"hard-code\" that. This means that
2733 it is invalid to have these specs after a variable-length spec. Well,
2734 you might not be arrested, but your summary buffer will look strange,
2735 which is bad enough.
2737 The smart choice is to have these specs as far to the left as
2740 This restriction may disappear in later versions of Gnus.
2742 General format specifiers can also be used.
