Changing keyboard shortcuts in Mail
I usually use command-shift-u to mark a message or a bunch of messages as read/unread. The problem is that if I typo and hit command-shift-y, it adds the email addresses from all highlighted emails into my address book. I'm wondering if there's a way to either disable or change this keyboard shortcut.
