key events in wpf?

Hi, I am trying to figure out how to make key input effect anything. In WinForms i had this:

Code:

---

Private Sub Form1_Keydown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyUp

        Select Case e.KeyCode
            Case Keys.Left

---

Is there a way to use key input?
