,----[ C-h k v ]

| It is bound to v, <menu-bar> <immediate> <view>.
| (dired-view-file)

| In Dired, examine a file in view mode, returning to Dired when done.
| When file is a directory, show it in this buffer if it is inserted.
| Otherwise, display it in another buffer.

(add-hook 'find-file-hook (lambda () (setq buffer-read-only t)))

,----[ C-h k C-x C-q ]

| It is bound to C-x C-q.

| Change whether this buffer is visiting its file read-only.
| With prefix argument arg, make the buffer read-only if arg is
