Over the past few years, I've become a Gmail expert and one of my favorite features is the keyboard shortcut 'a' that allows me to archive an email. I'm not sure if that's the default or I set it as a shortcut. Now for my work, I'm setting up Outlook 2010 and shortcuts like that. But I'm not sure how to set up custom keyboard shortcuts for Outlook 2010. I'm looking for a one-key shortcut, not three keys at the same time.
