hi, i think accesskey should works in all activable elements... its important to make html5 custom-widgets accessible...

but i don't know what newest specs says but in this example the <b> element do not receive the activation ("click" event dispatch) by

1 - accesskey, alt + maiusc + b
2 - enter keyboard button when focused

<b accesskey="b" onclick="alert('hi');" tabindex="0">hi</b>

but these works good:

<button accesskey="c" onclick="alert('hi');" tabindex="0">hi</button>
<a accesskey="d" onclick="alert('hi');" tabindex="0">hi</a>

Reproducible: Always
> but i don't know what newest specs says

For elements that don't "define a command" (such as this case) it says:

  1)  If the element is focusable, run the focusing steps for the element.
  2)  If the element has a defined activation behavior, run synthetic click
      activation steps on the element.
  3)  Otherwise, if the element does not have a defined activation behavior, fire
      a click event at the element.
hi boris,

"element has a defined activation behavior" == element has a "click" event listener 


what is the meaning of "activation behavior" according to the spec?
As per the below spec

the elements having tab index attribute are focusable and if it does not otherwise have an activation behavior defined has an activation behavior that does nothing. 
This means that an element that is only focusable because of its tabindex attribute will fire a click event in response to a non-mouse activation (e.g. hitting the "enter" key while the element is focused).

From the spec it looks like even if the element has empty activation behavior, if it if focusable because of tab index attribute click event is fired on pressing enter key.
Can someone please update whether firefox is interested in implementing this behavior? (Sending simulated click on keypress of enter key)
