Easy, short and no need window focus:

Also here a usefull list of Virtual Key Codes

        [DllImport("user32.dll")]
        public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

        [DllImport("user32.dll")]
        static extern bool PostMessage(IntPtr hWnd, UInt32 Msg, int wParam, int lParam);

        private void button1_Click(object sender, EventArgs e)
        {
            const int WM_SYSKEYDOWN = 0x0104;
            const int VK_F5 = 0x74;

            IntPtr WindowToFind = FindWindow(null, "Google - Mozilla Firefox");

            PostMessage(WindowToFind, WM_SYSKEYDOWN, VK_F5, 0);
        }
