With it, you can use your Xbox controller to move around the screen and type.

Does that mean you couldn't before? Seriously people were playing around on a handheld that couldn't even type?

Button accelerators are also available; these include the X button for backspace and the Y button for the spacebar.

For better movement patterns, the keyboard keys are aligned vertically."
