Maybe in addition to these obscure codes,
have plain English:
Example:
%x = %{xref}

    gnus-summary-line-format is a variable defined in ‘gnus.el’.
    Its value is
    "%U%R%z%I%(%2t %3{%~(cut-left 2)~(max-right 6)~(pad 6)o%}%3L|%6us|%-22,22f%)%3{%un%}:%s
    "
    Original value was 
    "%U%R%z%I%(%[%4L: %-23,23f%]%) %s
    "

      You can customize this variable.

    Documentation:
    The format specification of the lines in the summary buffer.

    It works along the same lines as a normal formatting string,
    with some simple extensions.
