Going through controls on form with arrow key?

$

I'm using the following code I found here in another thread, to enable the arrow keys on my keyboard to move a rectangle around in a picture box instead of cycling through the controls on the form. This works, but I have a question if I'm doing this right. I have four buttons on the form. Do I have to place this in every button? and do I have to place it in every control I add? or is there a simpler way to do this.

Code:

    Private Sub btnR_PreviewKeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.PreviewKeyDownEventArgs) Handles btnR.PreviewKeyDown
        Select Case e.KeyCode
            Case Keys.Up, Keys.Right, Keys.Down, Keys.Left
                e.IsInputKey = True
        End Select
    End Sub
