Fullscreen Video Menu

When the Video-node is fullscreen "options" key-press causes audio/subtitle track-menu appear. What if I don't want it to appear? I want to configure subtitles and audiotracks in my code. How can I prevent this?

function onKeyEvent(key as string, press as boolean) as boolean
    handled = false
    if(press)
        if(key = "options")
            handled = true
        end if
    end if
    return handled
end function
