This closes all filter groups when I enter ibuffer. (defun ibuffer-toggle-all-filters () (interactive) (if (not (eq major-mode 'ibuffer-mode)) nil (progn (goto-char 0) (setq prev-point 0) (ibuffer-forward-filter-group) (while (< prev-point (point)) (setq prev-point (point)) (ibuffer-forward-filter-group) (ibuffer-toggle-filter-group))))) This does what I want, but it's really slow. Any suggestions on how to speed it up? Thanks, Joel -- Joel J.
