I'm using [fholgado's fork](https://github.com/fholgado/minibufexpl.vim) of the MiniBufExplorer plugin with Vim 7.4. I'd like to setup a map in my `.vimrc` to delete/close all open buffers, but nothing I've tried has worked.

Examples:

```
nmap <leader>bda :MBEbd 1,1000<cr>
nmap <leader>bda :1,1000 MBEbd<cr>

```

From the plugin's documentation:

```
:MBEbd[!] [N1] [N2] ...                                               *:MBEbd*
    Delete buffers but preserve the window that holding them.
    [N*] is the buffer's number or name to be deleted. If no [N*] is given,
    then current buffer will be deleted. Multiple buffers could be deleted
    at the same time.

```

Any idea how I can accomplish this?
