Via melpa: M-x package-install ido-describe-bindings.
You may want to bind ido-describe-bindings to a convenient
keystroke. In my setup, I bound it to b in help-map.
By default it is C-h b.
(eval-after-load 'help
(define-key help-map (kbd "b") 'ido-describe-bindings))
You can configure ido-vertical-mode or ido-grid-mode
