#+TITLE: Expanding a Directory With Tab in Dired Mode

=dired= mode is one of my favourite features of Emacs. I use it so
often, it's pretty much my go-to file browser. I use it both on my
local machine, and on remote machines via TRAMP. One feature of
=dired= is the ability to enter sub-directories in the same buffer by
inserting the contents under the current directory. While this is
useful, I often want something quicker to check the contents of a
directory without either opening it in a new buffer, or inserting it
below.
The workaround for this I use is by using the excellent [[https://melpa.org/#/dired-subtree][dired-subtree]]
package and the following ~use-package~ definition.
#+BEGIN_SRC elisp
(use-package dired-subtree
:ensure t
:after dired
:bind (:map dired-mode-map
("TAB" . dired-subtree-toggle)))
#+END_SRC
Now whenever I want to expand a directory, I move my cursor over it
and press the @@html: <kbd>Tab ↹</kbd>@@ key. Pressing
@@html: <kbd>Tab ↹</kbd>@@ again on the same entry will collapse it
and hide the contents again.
