Code of conduct

• [X] I agree to follow this project's code of conduct.

Impacted component(s)

Slider, SliderHandle

Description of the requested feature

We'd like to have a feature implemented in Slider or SliderHandle to provide a default-value. If the user would then double click on the slider or the handle the value would reset to the provided default-value.

Mockups or screenshots

No response

Implementation notes or ideas

I tested also detecting a double click on the slider track. This might be possible to let the user even reset a slider when not double clicking on the slider handle. We need to consider resetting values also for keyboard-users. Maybe we can use Escape key when the handle has focus to reset to default value (if given).

Please also consider touch users, screen reader users and voice recognition users when thinking about how this should work.

@jnurthen do you have concerns about accessibility with the core spec?

If so, is there an alternative input to a double-click that you would recommend replacing the Spectrum behavior with?

[jnurthen]

I have concerns - it doesn't appear to take account of any input mechanisms other than pointers

I filed https://jira.corp.adobe.com/browse/SDS-12156

Needs some testing on touch users, screen reader users and voice recognition
