Fine adjustment in sliders

Hi All,

I´m well aware that sliders can be precisely adjusted by double clicking and imputing the value, but...

Wouldn´t it be nice to be able to adjust them by left-right arrow key strokes according to their step value?

I know it would be really resource consuming as each keystroke would likely mean a recomputation of the whole solution but I think it could be really user friednly when trying to achieve the right solution "by hand".
