How to use Outlook.com e-mail with keyboard shortcuts
The keyboard shortcuts for Outlook.com have been updated from Hotmail. Some of the shortcuts may be familiar, but you'll definitely want to check out the new ones.

Outlook.com is out of preview now and available for everyone to use. Learning how to get around the new interface can be a lot easier with the help of keyboard shortcuts. So whether you're new to Microsoft's browser-based e-mail service or an old Hotmail user trying to adjust to the new design, give the shortcuts a try and get to know Outlook.com.
Before we get started, go to Settings > Keyboard shortcuts and make sure that keyboard shortcuts are enabled and set to Outlook.com mode. If you're already familiar with the keyboard shortcuts for Yahoo! Mail or Gmail and prefer to use those instead, you can change to one of those modes from here.
