You can of course have mix of bound and unbound forms if you add a sub_form or two but this will still probably need some coding to automate and join any relationships between forms (if required). Also, a 'bound' form can have a mix of controls of bound (to a field) and unbound (no data values) items to provide a smoother interface that would otherwise be too clumsy by design to stick with just the one type.
In fact, trying to cancel a record is not always obvious or user_friendly as the ESC (escape) key has a two folded response; the first to the field your cursor is active and second the entire record. Yes, you can undo record changes but this should not be relied upon. It does provide automatic relationship links between your tables providing you are using primary keys and other linked fields between tables correctly without the need to manually intercede.
