Coarse and fine control of window and level sliders using shift, control, or alt keys

[erentar]

Is your feature request related to a problem? (optional)

It is difficult to dial a precise level and window using the sliders, especially if the image dynamic range is very large.

Description of the new feature/enhancement

Once the slider is selected, the arrow keys allow for very fine adjustment of level and window, changing it by one.

I want the shift key to change it by 10, and ctrl key to change it by 100; for example.
Using the mouse, especially with touchpads or lower resolution mice is difficult.

Having coarse and fine keyboard control over these sliders would help immensely.
