If you need more control over the completed item's snippet expansion, you might need these two APIs to help program your key mapping.

ncm2_snipmate#completed_is_snippet()

Checks whether the v:completed_item is also a snippet.

<Plug>(ncm2_snipmate_expand_completed)

Use this key to expand the completed snippet.
