How to configure in IdeaVIM Ctrl + N and Ctrl + P completion from Vim?

Question

In Vim we can use Ctrl + N or Ctrl + P to finish code completion. How to configure it in IdeaVim for IntelliJ?

Answer 1

I could not get CTRL-N and CTRL-P to work after mapping them to "Cyclic Expand Word" and "Cyclic Expand Word (Backward)" in IDEA 2016.2.5 (while running IdeaVIM). Both keystrokes just did nothing.

The solution was to additionally select "Settings" from the File Menu, then "Other Settings" -> "Vim Emulation", and set the "Handler" for Ctrl+N and Ctrl+P to "IDE" instead of "Vim".
