Are you familiar with the concept of “transpointing windows”?

Conceptually it’s similar to what you’ve done with hyperlinks here (and it’s part of early conceptions of hypertext — being an important part of Xanadu, though not Memex). Basically, you have some n corpora, in windows or columns, and associated sections are highlighted and then connected with a line or a rhombus; when a highlighted section is selected, associated sections in other windows scroll to align to it.

(There’s a little more complexity: highlighted sections can overlap, and you can have connections to multiple non-contiguous sections of the same corpus, both of which present problems that make UI behavior necessarily less obvious.)
