强推 C-x C-j (dired-jump) 。超高频使用的快捷键。

Emacs 26.3 默认没有绑定。

如果只是用这个，改下快捷键就好。

另外 dired＋ 有很多功能。加载它后会自动绑定，dired-jump 就会自动帮你绑定。

C-x C-j runs the command dired-jump (found in global-map), which is an
interactive autoloaded compiled Lisp function in ‘dired-x.el’.

It is bound to C-x C-j.

(dired-jump &optional OTHER-WINDOW FILE-NAME)

Jump to Dired buffer corresponding to current buffer.
If in a file, Dired the current directory and move to file’s line.
If in Dired already, pop up a level and goto old directory’s line.
In case the proper Dired file line cannot be found, refresh the dired
buffer and try again.
When OTHER-WINDOW is non-nil, jump to Dired buffer in other window.
When FILE-NAME is non-nil, jump to its line in Dired.
Interactively with prefix argument, read FILE-NAME.

没装helm或者ivy或者snails吗，装了之后一般backspace就是上一级
