Question

How can I toggle an event every time F2 is pressed by the user?

if(/*is pressed F2*/){
    this.Close(); 
}

Thanks in advance!

Answer 1

First create a key down event like :

    private void form1_KeyDown(object sender, KeyEventArgs e)
    {
        if ( e.KeyCode == Keys.F2 ) 
            this.Close();
    }

And for getting keys when you press the key on the controls of form1 : change form1’s KeyPreview to true on form1’s page_load event

    private void form1_Load(object sender, EventArgs e)
    {
        this.KeyPreview = true;
    }
