2.1 Optional Installation File At Point

If you choose to have dired-x.el bind dired-x-find-file over find-file (see Find File At Point), then you will need to set dired-x-hands-off-my-keys. To do this, either set it before dired-x.el is loaded, or use M-x customize-variable, or call dired-x-bind-find-file after changing the value.

(with-eval-after-load 'dired
  ;; Bind dired-x-find-file.
  (setq dired-x-hands-off-my-keys nil)
  (require 'dired-x))
