Create Multiple range Sliders

I want to be able to change what the steps are based from.

Example:

Step: 5
Min: 13
Max: 29
Value: 16

With these configs, the possible values of the slider are:

13, 18, 23, 28, 29 (with an initial value of 16 that cannot be selected after you slided to something else)

But it would be nice to be able to set 0 (or anything else) as the starting point for steps, which would gives:

13, 15, 20, 25, 29

I guess, ability to disable some segments in Range Slider ('busy' segments) would be quite necessary.

The up arrow arrow key increments
the pgUp key increments
the Home key goes in the oposite direction that the above two keys go.

The Home, upArrow, and PgUp keys are all at the top of the keypad
and it is natural to think they would move that way.

The Home key move down to the min value instead of to the max value.

The same applies to the 
End, downArrow, and PgDn keys but in the opposite direction.

Make the Home key go twords the max value
and the End key go twords the min value.



The up arrow arrow key increments
the pgUp key increments
the Home key goes in the oposite direction that the above two keys go.
