* Interactions should be extended to allow to specify a control that triggers the action. The concept is described by InidieUI: you can use mouse, touchscreen, keyboard, voice control or a control element to invoke the action. Maybe Interactions should be renamed to Triggers to share terms with IndieUI. | |||
Here's the image of InideUI action/interaction concept. | |||

Alternatively we could introduce relations between actions like "triggers" and "triggeredby". | |||
* What about highlevel actions (uberactions), for example, "press" buttons means "send something somewhere". This may be covered by label. Another example, selected listitem on the left changes a view on the right, "select" actions has meaning of "change view". Or checkbox that enables/disables related controls, "check/uncheck" action means "enable/disable controls". These examples correlates to controlledby/controllerfor relations, but the relations doesn't reveal type of control. | |||

[to be done conflicts between native semantics, ARIA and this API, I tend to think that the author should be able to replace/remove native semantics if needed. This can ruin the web page but it gives the absolute control over the page content. A dangerous but quite powerful tool like atomic energy. ] | [to be done conflicts between native semantics, ARIA and this API, I tend to think that the author should be able to replace/remove native semantics if needed.
