Allow Pressing Enter to Save Metadata

Editing a lot of metadata, using the metadata editor. I want to press enter to save changes and close the dialog, but I have to manually click the save button.

Could you add Enter as a shortcut to save?

Also, it would be awesome if the full path (the first item in View Details) was shown in Edit Metadata, so I could know which file I'm editing.

btw, I am editing metadata because I have many movies with multiple versions ripped (theatrical, unrated, special edition, director's cut, etc.)
