Trigger paragraph view on hover

It would be great to be able to see contents of a paragraph on hover over an item on a map. 2 motivations:

1. when I edit an item (Item A) in the editor and would like to see content of another item (Item B), I have got only one option: to click on the Item B, read the content, find the Item A on the map, click to come back to editing. I had content paragraph shown on hover, it would look like: I keep editing Item A, keep Item B on a map, hover over it, view content of a paragraph of Item B, switch to editor to continue editing Item A, repeat the process with Item B or any other item, without loosing the editors context.

2. the second motivation is the ability to export it to interactive complete HTML page where a content could be browsed as a map with some paragraphs shown on hover, while a reader is viewing it

Would something like this be possible?
