I am using gnus to read my email and the current setting for the gnus-summary-line-format in my .gnus.el is
(gnus-summary-line-format
"%U%~(pad-left 5)R: %~(max-right 25)D | %~(pad-right 25)~(max-right 25)a | %~(max-right 50)s \n")
Is there a way to modify this setting in order to show a short preview of each article in the summary buffer (say the first line, or the first x characters of the corresponding email) ?
This question is raised in EmacsWiki but I could not find answer.
Thanks for your help
