Vim file navigation

To navigate through directories and to open files I use NERDTree plugin. The plugin opens small buffer on the left which contains the file system tree.

If you want to pull up NERDTree so it's always visible docked to the left of your Vim window you can type:

:NERDTree

Also NERDTree allows to modify the file system tree. Hit key 'm' and it will open menu with some option.

To refresh the file system tree simple hit key 'r'.
