You can set a keypreview property on the form, I thought, which means the form gets to preview all keys.

As far as I know there is nothing as easy as simply enabling KeyPreview. Instead you'll have to use hooks that however are well covered by many internet resources. You can start from this CP article Using Hooks from C#[^]

    private void YourForm\_KeyDown(object sender, KeyEventArgs e)
    {
        if(e.KeyCode.ToString()=="Escape")
        Application.Exit();
    }
