Was this something which used to work for you, and then stopped?

I never saw this working

Describe the bug

In insert mode, if the insert position is not in the beginning of lines, when I press c-r, it only shows ", but no popup windows. In normal mode it works no matter it is in the beginning or in the middle of lines.

Do you have a config file available? Maybe some other plugin is causing this.

Thanks for the prompt reply!

Actually I have quite a few, and I not sure how to debug. As far as I could tell, none of them use the kep mapping of ctrl-r.

That's quite a lot indeed. What does :imap print?

It looks <c-r> is used by registers.
