        %       is replaced with the current file name                  *:_%*
        #       is replaced with the alternate file name                *:_#*
        #n      (where n is a number) is replaced with the file name of
                buffer n.  "#0" is the same as "#"
        ##      is replaced with all names in the argument list         *:_##*
                concatenated, separated by spaces.  Each space in a name
                is preceded with a backslash.
Note that these give the file name as it was typed.  If an absolute path is
needed (when using the file name from a different directory), you need to add
":p".  See |filename-modifiers|.
Note that backslashes are inserted before spaces, so that the command will
correctly interpret the file name.  But this doesn't happen for shell
commands.  For those you probably have to use quotes: >
        :!ls "%"   
        :r !spell "%"
