完成尝试后，omnicppcomplete 将在弹出菜单中显示所有可能的项目.要选择菜单中的某个项目，应使用 和 在不同项目之间来回切换.我觉得很不方便.如果可以用j和k来代替和，那应该很酷了.C-P> .那我该怎么办?

After a completion try, omnicppcomplete will display all the possible items in the pop up menu . To select an certain item in the menu, one should use <C-N> and <C-p> to switch back and forth between different items. I feel that it is very inconvient . It should be very cool if j and k can be used to to take place of <C-N> and <C-P> . so how should I do ?

function! OmniPopup(action)
    if pumvisible()
        if a:action == 'j'
            return "\<C-N>"
        elseif a:action == 'k'
            return "\<C-P>"
        endif
    endif
    return a:action
endfunction

inoremap <silent>j <C-R>=OmniPopup('j')<CR>
inoremap <silent>k <C-R>=OmniPopup('k')<CR>
