Custom button config with mouse and kb

[NeezyDeezy]

I'm trying to assign keys to do certain things in certain programs, is this possible?

I want my left thumb button to be "windows button+d" to take me to my dektop, but that won't work wth logitech's provided software because it only allows compound buttons with alt shift and control.

I'd also like to be able to click my scroll wheel and have the kind of scroll where the scroll is extremely smooth and I control the speed by moving the mouse farther up and down. My old mouse does this but I can't figure out how to configure this with the new one.

I also want the thumb down button to be set to "open in new tab" in firefox. Is this possible?

Thanks for any advice you can give me. Do I jst need some software program I don't know about?

If I set button 2 ,which is the scroll wheel on my Logitech Trackball, to "Center Button" I get the scrolling action you describ. You would think that the "universal scroll" setting would be the one you want but it doesn't give you the smooth scroll action. I don't have any extra buttons on my trackball so I use the scroll wheel button push as a back button.
