inoremap <expr> j pumvisible() ? "\<C-n>" : "j" doesn't work.

[Blackbird314]

After I add the config inoremap <expr> j pumvisible() ? "\<C-n>" : "j" to .ideavimrc, when I press key j the character “j” will appear for about 0.5 seconds then disappear.

IdeaVim doesn't currently support the pumvisible Vim function, so this mapping won't work. Following the StackOverflow link, I'm not aware of a way to make IdeaVim move the completion selection up/down with j/k, sorry. I'm also not entirely sure how it could work without a similar mapping. Since you're in insert mode, j will naturally be inserted as though typed.

Thanks for your reply, maybe I have to use ctrl-j shift-j to replace j...
