您可以创建一个单一的Map来完成所有事情：

" the function where everything happens
function! MagicPaste()
    " create a new buffer, see :help :enew
    enew

    " grab the content of register "+
    let reg = getreg("+", 1, 1)

    " figure out how many empty lines there are at the top
    " and remove them, if any
    let i = 0
    while reg[i] == ""
        let i += 1
    endwhile
    if i > 0
        call remove(reg, 0, i - 1)
    endif

    " insert the the remaining lines in the buffer,
    " see :help setline() and :help getreg()
    call setline(1, reg)

    " perform filetype detection
    filetype detect
endfunction

" the custom mapping
nnoremap <key> <Cmd>call MagicPaste()<CR>
