Believe me, I knew you wanted the more interactive way - not to clik, but to continuously show the value ;) Well, I think this feature is not directly available, but I'm pretty sure a small fix should enable it.
I'm not this kind of a programmer, but the click interrupt must somehow be replaced with something contnuosly - a while loop, or something - and then be terminated by a key stroke or click or whatever. I guess this need source code hacking. Maybe someone reading this can help us out here? I'd really like this option myself.
