Input value control via Middle Mouse Button?

A few versions back (maybe 3 or 4), when I still had Filter Forge on a Mac, I noticed that in some filters, you could control the input value by selecting the value and then scrolling up and down with the middle mouse button... Sort of like how you can select scaling percentage in Photoshop and then slowly scale the selection up or down until it looks right.
In the few filters that this worked with, it was pretty helpful for fine tuning an effect.
For whatever reason, it only worked on some filters and by the next version that ability seemed to have stopped...
I've since switched over to windows now and it does not seem to be a thing that exists for PCs.
I keep wishing this feature would show up again, but I never bothered to ask about it.
So...
Is something like that possible? Or was it just some Mac specific anomaly?
Am I the only one who would find this helpful?
Well... That's all, I thought I'd finally put this out there if it's something worth considering.

Btw, that doesn't seem to work with value controls.

Right, got it. Still, would be nice to have that control. I guess that would need some custom GUI stuff. Perhaps a Houdini style middle mouse hold and drag?

Sorry, to reply so late, I was very busy with some work issues and forgot that I had posted this and I guess the forum didn't notify me of a reply.

I think I described this poorly...

What I meant was for example, if one were to go to the settings menu and chose an option like "variation", "hue" or "scale", there is usually a slider control and next to that there is an input box... Normally there is some preset value in the input box...
Let's say for example "50"... If you were to select/highlight the numbers and rotate the middle mouse wheel (scroll button) the value would increase or decrease as you spun/rotated the wheel.
Currently if you do that the whole menu scrolls up or down and the value remains unchanged.

This was probably a quirk particular to Macs... I went back to my old Mac and looked through a bunch of filters trying to find one that did that, but I couldn't find any... It was probably version 2 of Filter Forge, because 3 was the last version I had on that Mac.

Anyway, being able to gradually increase or decrease a value using the mouse's middle wheel would be pretty useful for fine tuning effects, like one can do in Photoshop (well, at least in CS5 which was the last version I had)...
Especially for inputs like "Variation", where one can see the changes one step at a time and go back and forth with ease when comparing.
