I would like to intercept while I push `CTRL + A + A`

I read the article
[How can I register a global hot key to say CTRL+SHIFT+(LETTER) using WPF and .NET 3.5?](https://stackoverflow.com/questions/48935/how-can-i-register-a-global-hot-key-to-say-ctrlshiftletter-using-wpf-and-ne/9330358#9330358)

and someone pasted a code originally posted here: 
<https://www.fluxbytes.com/csharp/how-to-register-a-global-hotkey-for-your-application-in-c/?unapproved=2279&moderation-hash=b3ec34d2621e0be051ed354f09c436d2#comment-2279>

Anyway, I tried to change the code adding and "&" but this and some other attempt was wrong.

How can I get if I press `CTRL + A + A` ?

Thanks for the help!

```
using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace GlobalHotkeyExampleForm
{
    public partial class Form1 : Form
    {

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        [DllImport("user32.dll")]
        private static extern bool RegisterHotKey(IntPtr hWnd, int id, int fsModifiers, int vk);
        [DllImport("user32.dll")]
        private static extern bool UnregisterHotKey(IntPtr hWnd, int id);

        enum KeyModifier
        {
            None = 0,
            Alt = 1,
            Control = 2,
            Shift = 4,
            WinKey = 8
        }

        public Form1()
        {
            InitializeComponent();

            int id = 0;     // The id of the hotkey. 
            RegisterHotKey(this.Handle, id, (int)KeyModifier.Control, Keys.A.GetHashCode());       // Register ctrl + a as global hotkey. 
        }

        protected override void WndProc(ref Message m)
        {
            base.WndProc(ref m);

            if (m.Msg == 0x0312)
            {
                /* Note that the three lines below are not needed if you only want to register one hotkey.
                 * The below lines are useful in case you want to register multiple keys, which you can use a switch with the id as argument, or if you want to know which key/modifier was pressed for some particular reason. */

                Keys key = (Keys)(((int)m.LParam >> 16) & 0xFFFF);                  // The key of the hotkey that was pressed.
                KeyModifier modifier = (KeyModifier)((int)m.LParam & 0xFFFF);       // The modifier of the hotkey that was pressed.
                int id = m.WParam.ToInt32();                                        // The id of the hotkey that was pressed.

                MessageBox.Show("Hotkey has been pressed!");
                // do something
            }
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            UnregisterHotKey(this.Handle, 0);       // Unregister hotkey with id 0 before closing the form. You might want to call this more than once with different id values if you are planning to register more than one hotkey.
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.Close();
        }
    }
}
