private bool _isFirstKeyPressedW = false;

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Control & e.KeyCode == Keys.W) 
    {
        _isFirstKeyPressedW = true;
    }
    if (_isFirstKeyPressedW) 
    {
        if (e.Control & e.KeyCode == Keys.S) 
        {
            //write your code 
        } 
        else 
        {
            _isFirstKeyPressedW = e.KeyCode == Keys.W;
        }
    }
}

Simple way is... There is a Windows API Function called ProcessCmdKey, by overriding this function we can achieve what we want

protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {
   if (keyData == (Keys.Control | Keys.C)) {
      MessageBox.Show("You have pressed the shortcut Ctrl+C");
      return true;
   }
   return base.ProcessCmdKey(ref msg, keyData);
}

Microsoft Documentation can be found here

if you want to handle Ctrl + C followed by Ctrl+ K you need to maintain a state variable.

Set the Form KeyPreview property to true and handle the Form KeyDown event.

Try This:

   this.KeyPreview=true;
   private bool isFirstKeyPressed= false;
    private void Form1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Control && e.KeyCode == Keys.C)
        {               
            isFirstKeyPressed = true;                
        }


        if (isFirstKeyPressed)
        {
            if (e.Control && e.KeyCode == Keys.K)
            {
                MessageBox.Show("Ctrl+C and Ctrl+K pressed Sequentially");
                /*write your code here*/
                isFirstKeyPressed= false;
            }
        }
    }
