How do I make the arrowkeys talk to Form1 instead of the radiobuttons?

Question

I have two radiobuttons inside a groupbox. And a picturebox I want to move around with arrow keys. Without the radiobuttons, everything works completely fine. But when the radiobuttons are added, it's like the radioboxes are selected, and all the arrow-keys do, is just alternating between different radioboxes.

Basically: How do I make the arrowkeys talk to Form1 instead of the radiobuttons?

You can override ProcessCmdKey() like this:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    switch (keyData)
    {
        case Keys.Left:
            pictureBox1.Location = new Point(pictureBox1.Location.X - 1, pictureBox1.Location.Y);
            return true;
        case Keys.Right:
            pictureBox1.Location = new Point(pictureBox1.Location.X + 1, pictureBox1.Location.Y);
            return true;
        case Keys.Up:
            pictureBox1.Location = new Point(pictureBox1.Location.X, pictureBox1.Location.Y - 1);
            return true;
        case Keys.Down:
            pictureBox1.Location = new Point(pictureBox1.Location.X, pictureBox1.Location.Y + 1);
            return true;
    }
    return base.ProcessCmdKey(ref msg, keyData);
}
