I finally got the <backspace> binded in ibuffer by "forcing" rebind like this: (eval-after-load 'ibuffer '(progn ;; use the standard ibuffer bindings as a base (set-keymap-parent (evil-get-auxiliary-keymap ibuffer-mode-map 'normal t) (assq-delete-all 'menu-bar (copy-keymap ibuffer-mode-map))) (evil-define-key 'normal ibuffer-mode-map "j" 'ibuffer-forward-line) (evil-define-key 'normal ibuffer-mode-map "k" 'ibuffer-backward-line) (evil-define-key 'normal ibuffer-mode-map "J" 'ibuffer-jump-to-buffer) ; "j" (evil-define-key 'normal ibuffer-mode-map (kbd "DEL") 'ibuffer-unmark-backward))) But the question is: why wasn't this binding "overwritten" from the "copy-keymap"?

Is there any "better" way of rebinding evil keys? Or, is it possible for Evil to handle this situation? Thanks, York
