Do you have any links to a description of how they should work or should I just use Sublime Text to see a canonical example?

That doesn't sound hard to implement iff you plan for those features from the beginning. I have my own editor hobby project and during my reading I got convinced multiple cursors are great for the reasons you described in your other comment.

I hadn't thought about multi cursor copy/paste so I'm wondering what else I've missed.

You should probably just check out Sublime Text, that's the best (almost only) implementation I've seen.

Someone posted a demo video of a modal text editor with multiple cursors to HN a year or so ago and I've been trying to track it down. Any idea what that might have been?
