If I understand what you're saying, you could certainly also navigate to the trashcan, hit Apple-A (select all) and then hit delete.... that's not *so* bad, is it?
when you are in mail message list view, instead of opening a message just slide your finger from left to right on the message you want to delete. way faster than opening the message and delete it!!
