NERD Tree Guide
The NERD Tree (GitHub: scrooloose / nerdtree) by Martin Grenfell is a
popular le system browser. If you’re using it simply to browse and
select les like a typical GUI IDE, then it’s worth spending a bit of time
going over the documentation, because this plugin does a lot more than
displaying a tree of les and directories.
With that in mind, here’s a guide to my favourite features and keyboard
commands.

Mirroring
If you want the tree to appear in the same state across multiple tabs,
then type

:NERDTreeMirror

. Any subsequent changes will be re ected

in each mirrored instance. This gives the feel of a traditional IDE, but
be wary of relying on it too much -- trying to use tabs this way is seen as
somewhat of an anti-pattern.

Keyboard Commands
Type

:help NERDTreeMappings

to read through all of the default

keyboard shortcuts. These are the ones I use the most frequently:
•

t

: Open the selected le in a new tab

•

i

: Open the selected le in a horizontal split window

•

s

: Open the selected le in a vertical split window

•

I

: Toggle hidden les

•

m

: Show the NERD Tree menu

•

R

: Refresh the tree, useful if les change outside of Vim

•

?

: Toggle NERD Tree's quick help

Typing

m

will display a menu that allows le system operations to be

performed from within NERD Tree. If you need to create a new le or
directory, then

ma

will show a prompt that allow a le name to be

entered.
I nd there are cases where NERD Tree’s visual representation of the
le system can aid understanding of a project’s structure, so it can be
useful to create new les from within it.

Further Reading
Dig into that

:help NERDTree

help le and have a look at the options

for customisation. And keep your NERD Tree up to date! This plugin
has had lots of contributors, and it was updated as recently as two
weeks ago.
