我已经更改了 [count] o 的行为/O使用以下映射。我认为这可以满足您的要求:

" o/O                   Start insert mode with [count] blank lines.
"                       The default behavior repeats the insertion [count]
"                       times, which is not so useful.
function! s:NewLineInsertExpr( isUndoCount, command )
    if ! v:count
        return a:command
    endif

    let l:reverse = { 'o': 'O', 'O' : 'o' }
    " First insert a temporary '$' marker at the next line (which is necessary
    " to keep the indent from the current line), then insert <count> empty lines
    " in between. Finally, go back to the previously inserted temporary '$' and
    " enter insert mode by substituting this character.
    " Note: <C-\><C-n> prevents a move back into insert mode when triggered via
    " |i_CTRL-O|.
    return (a:isUndoCount && v:count ? "\<C-\>\<C-n>" : '') .
    \   a:command . "$\<Esc>m`" .
    \   v:count . l:reverse[a:command] . "\<Esc>" .
    \   'g``"_s'
endfunction
nnoremap <silent> <expr> o <SID>NewLineInsertExpr(1, 'o')
nnoremap <silent> <expr> O <SID>NewLineInsertExpr(1, 'O')
