Thanks for the quick reply.

I've been using the pre-packaged version.  It seems like there's no way to
do what I want with the existing code, so it probably makes sense for me to
try building from git.

Are you suggesting that a new attribute, annotation-id, be added to span?
I think that's what you're saying, but I want to make sure we're on the
same page.  If attribute-id got duplicated due to dicing and splitting of
spans, that would be fine for my purposes -- I could easily use the first
and ignore any subsequent ones.

That would be the simplest way to do it, but it seems like one could link
directly by using JQuery again, something like scrollIntoView?

It does help, thank you.  If an annotation-id was added to the highlighted
spans, then I think I could create the functionality I need via a plugin.
Without it, I'm not sure where I'd begin.

How would you like to proceed?  It seems like until 2.0 is released I'm
going to have to build from git to get this functionality, so I might as
well go ahead and do that.  I can take a stab at modifying the highlighter
once I've done that, although I'm also perfectly happy to have you add it
in - I bet you'd be much faster.  :)
