For keys like C-a you also need to hit C-q.  It's not 100% compatible.

But wait: What I find confusing is that I also need need to confirm for
`jump-to-register'.  Is this intended?

In Helm or in vanilla Emacs?  I don't see that for M-n in vanilla Emacs.

Oh, and there is a little bug when the register binding list is empty
(e.g. after restarting Emacs): your code errors because Emacs does not
pop up a preview window in that case.
