try to create HotKeys for my forms

code

    private void FormMain_KeyPress(object sender, KeyPressEventArgs e)        
    {
        if (e.KeyChar == (char)Keys.Enter)
        {
            MessageBox.Show("e");
        }
    }
works for one key, but if I whant to use combination of keys like CTRL+N, try to use if (e.KeyChar == (char)Keys.Enter && e.KeyChar == (char)Keys.N) - but it's not working. I'm I right - using such code for keys combination?
