Use leader-return to open the current file's directory in finder. This only works on OSX of course. Very useful for quickly getting to a project or rearranging files.
Note: set autochdir
Makes vim automatically match its current working directory with the current buffer (if that buffer has a file).
Substitute out the mapping for whatever is convenient for you.
