Yes, because the scroll wheel also zooms in/out not only in Blender but also in SL, so it is a common muscle memory behavior. Likewise alt-hold move mouse slews left/right and zooms up/down. alt-left-click centers on the pointer position. alt-shift-hold move mouse orbits CCW/CW left/right, up/down on up/down
Not all of the Blender and SL cam movements are identical, but a goodly number are the same or similar.
