 public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

        }

        private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("button1 was clicked");
        }

        protected override bool ProcessCmdKey(ref Message msg, Keys keyData)

        {
            KeyEventArgs e = new KeyEventArgs(keyData);
            if (e.KeyCode == Keys.F1)

            {
                button1_Click("", e);
            }
            return base.ProcessCmdKey(ref msg, keyData);
