"What links here" for Beans I'm using an Entity Reference field (unlimited entries) and a View to include desired Beans on node pages. How can I create a view similar to node/%/backlinks which allows me to see all the nodes that reference a particular block?

So far, I have a View of Content. It includes a relationship to the Referenced Entity (Block) and a Contextual Filter on Block ID. I want to include this View as a menu item on the Block itself, but blocks aren't displayed with their BID, they use a transliterated version of the label as an alias.

I need to find a way to access the Block ID from the alias, or somehow expose a transliterated version of the Label through Views.
I think your problem is that you are focusing on the label. You need to use a contextual filter of 'Block: Block Delta'. Then you can add a menu tab to views using this path: 

block/%/back-links
