2962 The variables `gnus-sum-thread-*' can be used for customization.
2963 %T A string with two possible values: 80 spaces if the article
2964 is on thread level two or larger and 0 spaces on level one
2965 %R \"A\" if this article has been replied to, \" \" otherwise (character)
2966 %U Status of this article (character, \"R\", \"K\", \"-\" or \" \")

2973 %t Number of articles under the current thread (number).
2974 %e Whether the thread is empty or not (character).

2978 %* If present, indicates desired cursor position

2980 %u User defined specifier. The next character in the format string should
2981 be a letter. Gnus will call the function gnus-user-format-function-X,
2982 where X is the letter following %u. The function will be passed the
2983 current header as argument. The function should return a string, which
2984 will be inserted into the summary just like information from any other
2987 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2988 with care. For reasons of efficiency, Gnus will compute what column
2989 these characters will end up in, and \"hard-code\" that. This means that
2990 it is invalid to have these specs after a variable-length spec. Well,
2991 you might not be arrested, but your summary buffer will look strange,
2992 which is bad enough.
2994 The smart choice is to have these specs as far to the left as
2997 This restriction may disappear in later versions of Gnus.
2999 General format specifiers can also be used.
