Why isn't this KeyPress method picking up my keyboard input?

private void Form1_KeyPress(object sender, KeyPressEventArgs e)
{
    if (e.KeyChar.Equals(Keys.Space))
    {
        this.Hide();
        restoreToolStripMenuItem.Enabled = true;
    }
    else if (e.KeyChar.Equals(Keys.M))
    {
        //If the menu is hidden, show it. Otherwise, hide it.
        if (menuTrayPanel.Tag.Equals("hidden"))
        {
            animationTimer.Tick += new EventHandler(displayMenu);
            animationTimer.Tick -= new EventHandler(hideMenu); //Don't trigger the hideMenu void when displaying it
            displayMenu(sender, e);
        }
        else
        {
            animationTimer.Tick -= new EventHandler(displayMenu);
            animationTimer.Tick += new EventHandler(hideMenu); //Same as with displaying, but the other way
            hideMenu(sender, e);
        }
    }
}
