load_auto_suggest_bindings._fill() equivelent for VI_MODE?

[Spitfire1900]

is there a VI_MODE equivalent to load_auto_suggest_bindings._fill() ( Fill partial suggestion.)?

I'm using Xonsh with prompt_toolkit and VI_MODe and I can't find an equivalent to Ctrl+-> to accept a partial completion.

Originally opened as #1859 but I probably should have opened up here first :D

This has been answered: xonsh/xonsh#4687 (reply in thread)

Annoying this required re-implementing _fill().
