NERD tree source code…

Install

Use git to check out the source code:

git clone git://github.com/scrooloose/nerdtree.git

Copy the nerdtree.git/plugin/NERD_tree.vim file to your local Vim plugins folder:
```
cp ~/src/nerdtree/plugin/NERD_tree.vim ~/.vim/plugin/
```

Configuration

To change the files which are ignored by NERDTree, add the following to your ~/.vimrc file:

let NERDTreeIgnore=['.pyc$', '\~$']

Note:

In this example, the only addition I have made to the default is to ignore pyc files. The items in the list are regular expressions.
To toggle the file filtering, use the f shortcut key.

Getting Started

Open a fresh NERD tree:

:NERDTree [<start-directory> | <bookmark>]

The root of the tree depends on the argument given. If no argument is given, the current directory will be used. If a directory is given, that will be used.

Commands

o	Open selected file/folder (also Enter).
go	Open selected file/folder, but leave cursor in the NERDtree.
t	Open selected node in a new tab.
i	Open selected node in a split window.
gi	Open selected node in a split window, but leave cursor in the NERDtree.
s	Open selected node in a new vertical split.
gs	Open selected node in a new vertical split, but leave cursor in the NERDtree.

Toggle

To toggle the tree on and off:

:NERDTreeToggle

To map this to the F2 key, add the following to ~/.vimrc:

map <F2> :NERDTreeToggle<CR>
