Documentation:
Group the buffers by the major mode groups on <C-down-mouse-1>? This number which determines (in a hairy way) whether <C-down-mouse-1> will split the buffer menu by the major modes (see 'mouse-buffer-menu-mode-groups') or just by menu length. Set to 1 (or even 0!) if you want to group by major mode always, and to a large number if you prefer a mixed multitude. The default is 4.
You can customize this variable.
This variable was introduced, or its default value was changed, in version 20.3 of Emacs.
