Sometimes it's extremely difficult to set a scene the way you want, because it jumps all over the place if you just move the dial (like x/y/z-Orbit) a millimeter. Other times you have to scroll the dial for a long time just to get to the position you want. 

You can adjust the sensitivity for each dial yes, but it's troublesome doing that all the time. So I thought if there was a script or something that could make e.g. the ctrl and alt buttons change the sensitivity of the dials +/- by a factor 10 or 100 or whatever (preferably user defined)? If not, would it be possible to create one?

I wonder why SM hasn't added this feature many years ago for this has been a problem with all versions of Poser until now (OK, haven't checked out 10/2014 yet but I guess it's still the same?).
