Suggestion:Metadata review keyboard shortcut customization

So right now when reviewing imported metadata <ALT>+<RIGHT ARROW> accepts the data and moves on, however the reject button does not have a corresponding keyboard shortcut, which means I go from using just the keyboard, to needing a mouse, and back to the keyboard any time I want to reject a book.

Can you give the reject button a key binding, and make both of those customizable in the settings?

Would make us old timers who use keyboard shortcuts a better day.

Thanks
