Not being able to rebind "drink" from Sneak+Right Click makes it difficult or impossible to use some mods. Some other mods also require sneak + right click to perform actions on entities you can drink from which also don't allow rebinding.

It'll be a bit of work but I'll try to get this in for the next release - the issue is that currently blood drinking isn't bound to shift+right click input combination, it's attached onto the sneaking + entity interact event combination. I'll have to redo a bit of the blood drinking stuff but it should be doable.

In addition to this the key combination is hardcoded in the lang file, it should be passed into the translatable component instead.
