I've just finished building my new Haswell rig. Trying to put things back together.

 

On my previous setup, I had a couple of the buttons on my Logitech M570 thumbball mouse programmed to zoom in and out. 

 

I know this was some little app or code that I found somewhere. The Logitech software doesn't work. I've tried searching and can't find it.

 

It's not a big deal but, it sure was handy. Better than the keyboard. 

 

Would appreciate any help here.

 

Thanks

Found what I needed in the Logitech SetPoint settings.
