Hello,

For horizontal sliders visually using the left and right arrow keys makes
sense for a keyboard user to change the values.
For screen reader users, is the expectation that the left and right or up
and down keys would work the same way?
Screen reader users wouldn't necessarily know what the orientation of the
slider is, it could be a volume slider like on Windows that visually
displays vertically, or it could be to identify a range and marked up
horizontally.

What are AT users and testers experiences with these slider components?

Thank you,

Beth

One thing to note, which isn't mentioned in the ARIA Authoring Practices Guide, is that aria-orientation should be set to indicate
the vertical/horizontal orientation of a slider.
http://www.w3.org/WAI/PF/aria/states_and_properties#aria-orientation

There are still some screen reader bugs associated with this attribute, which can be seen by comparing feedback at
Horizontal: http://whatsock.com/tsg/Coding%20Arena/ARIA%20Sliders/Horizontal/demo.htm
Vertical: http://whatsock.com/tsg/Coding%20Arena/ARIA%20Sliders/Vertical/demo.htm

In JAWS16 for example, in IE11 and FF, if you set focus to the slider in Forms Mode then tab out then into the slider, it will
announce the literal opposite of what it should be doing for the proper orientation, saying that a horizontal slider is a "Up Down
Slider", and the vertical slider is a "Left Right Slider". This is a bug in JAWS however.

I'm not sure, I have a list of bugs to enter, but haven't had the time to do it as quickly as I wish. If you want to take care of
this one, please feel free.
