The higher the value of the variables gnus-button-*-level
,
the more buttons will appear. If the level is zero, no corresponding
buttons are displayed. With the default value (which is 5) you should
already see quite a lot of buttons. With higher levels, you will see
more buttons, but you may also get more false positives. To avoid them,
you can set the variables gnus-button-*-level
local to
specific groups (see Group Parameters). Here’s an example for the
variable gnus-parameters
:
;; increase gnus-button-*-level
in some groups:
(setq gnus-parameters
'(("\\<\\(emacs\\|gnus\\)\\>" (gnus-button-emacs-level 10))
("\\<unix\\>" (gnus-button-man-level 10))
("\\<tex\\>" (gnus-button-tex-level 10))))
