The Custom element Slider provides keyboard navigation once it gains focus(either programmatically or as a result of a user click). When the widget is focused, you can use the keyboard to change its value.
Tab - Like other widgets, the jqxSlider widget receives focus by tabbing into it. Once focus is received, users will be able to use the keyboard to change the slider's value. A second tab will take the user out of the widget.
Shift+Tab - reverses the direction of the tab order. Once in the widget, a Shift+Tab will take the user to the previous focusable element in the tab order.
Right Arrow and Up Arrow - increase the value of the slider.
Left Arrow and Down Arrow - decrease the value of the slider.
