I'd like to remove any unused keys from my mods. Is there any well to tell what object a particular key operates on? Neither 'Info' from the CS or 'Uses Info' from MWEdit yields such information. I'd try Enchanted Editor but the mods are so big I think they'd take a week to load.

It might be tricky since key use on an object is part of its local reference data.

You mean you want to remove unused keys from the game? Because if it's your mod, you should know what the keys work on, if you added the keys to the mod.

Or, do you want the keys to go away after they are used? That would need a script.
