OS X + Vim: Open Finder for a Folder in NerdTree (Vim)

Question

I use the NerdTree plugin for MacVim religiously, and find myself often wanting to open a folder in the Finder to work with the files. An example would be wanting to preview and copy some images.

Is there a quick way to do this that doesn't involve changing the current directory? My perfect scenario would be:

• Move cursor to desired folder
• Press "some key"
• Folder opens up in the finder.

Answer 1

The shell command to open a folder is

$ open /path/to/folder

In a Vim function, this command could be invoked like this:

let g:mypath = /path/to/folder
execute "silent !open " . g:mypath

NERDTree's documentation has a simple and easy to follow example that you can expand using the global objects listed above.
