How do I use my Racial Power?

To unleash your awesome racial powers, first go to your magic menu. Then, select your power. Finally, unleash it with the Z key . The Z key is also the key that shouts are mapped to, so you can only have one shout or racial selected at a time.

Console equivalents are RB on the Xbox 360, and R2 on the PS3.

When playing on an xbox with the Kinect you need to depress both the LB and RB.

The shout is mapped to the Z key (on some keyboards like the german one, it's the Y key), you don't need to equip it onto a specific hand. You do however need to activate a shout by absorbing a dragon soul, if you haven't done so yet.
