A wireless bluetooth combination, I hadn't thought of that. The hidden link is provided as a fallback for users with screen readers that don't support the use of ARIA, but if a keyboard is being used, it should be possible to set focus to the slider itself, since it is already programmed to be keyboard accessible, then the arrow keys would move the slider? Then again, I seem to remember that the arrow keys on Voiceover move focus instead of passing this through to the control.

I'm not sure why the time slider would bounce focus. It literally uses the same setup script as the first slider, the only difference is the CSS which makes it a vertical slider instead of a horizontal one, and aria-orientation="vertical" is set on the slider. 

I tried this using the gestures and didn't have a bounce effect. Which mode of navigation does this happen on? Also, it's important to move the first slider to 0% before trying the Time slider, because the image that opens will obscure the second slider.

The Time slider also has a hidden link fallback that opens a standard select as well, which is intrinsically bound to the slider.

  Bryan, that is a fantastic gesture to learn!  Works great for gesture interaction.  Is there a corresponding bluetooth wireless keyboard key combination to interact with the slider? 
  The only thing I can find is to "select" the slider bar brings up a popup button to set the value. 

  Also, any idea why on this demo when I navigate to the "time" slider, the page resets and the focus goes to the top of page?

  This would be the page at 
  http://whatsock.com/modules/aria_slider_module/demo.htm 
    
  Voiceover incorrectly says that you should swipe up and down with one finger to adjust the slider, but David gave the correct sequence earlier, which is to double tap and hold with one finger, wait for the pass-through sound, then slide your finger in the direction you want to drag the slider.

  I couldn't get anything to 'slide' in iOS, with or without VoiceOver, I just used the buttons. 

  Perhaps we're talking at cross-purposes, which page do you mean?

  The carousels are fine in Voiceover, I worked on these a while ago. For some reason Voiceover on iOS isn't paying attention to aria-hidden="true" when included within a button element. That's a bout it though.

  What was the issue there? I tried the carousel and slidershow, they seemed ok. Could adjust the ordering a little to make it easier to understand (and don't rely on having an esc key), but it seemed ok.
