I'm trying to use the keyboard shortcut in mail to mark messages as read or unread. I've been using OS X for about 3 years now and have never been able to figure out what the up and down arrow keys are. For example, in Mail you use "Up arrow" Command and U to mark a message as unread. Like I said, I can't figure out the first key. Any help is appreciated!
