org-ref should not get any credit for this. That is a feature of the built in org-cite library, which uses completing-read for that behavior. completing-read is only for reading one thing at a time, and org-cite works around that in a way that leads to the behavior you see.

It looks like helm (if you use helm-mode), but it is actually the helm version of completing read, and not a helm selection command. 

Other completion backends use different bindings, e.g. ivy uses C-M-j I think.

Hello,

I'm finding myself stuck in the `HELM Org Cite Insert` buffer that lists possible citations after calling org-cite-insert using Helm. After selecting a reference I am prompted to select more, and there isn't an obvious way to say, 'Thanks org-ref I'm done, kill this minibuffer and insert the refs I have chosen.'

I was eventually told on Stack Overflow that M-RET does the job, but I would have expected either the first option in the HELM buffer to do this, or else there to be an option in the HELM Select Action list?

Thanks!
Daniel
