Re: Proposal to change documentation on tabindex to strongly discourage values greater 0

In my opinion the tabindex shall be moved to CSS as nav-index or tab-index with current behaviour and values because the tab order is dependent on layout of website. For example absolute or fixed positioning to bottom. Only meaning of 0 shall be clarified as FIRST FREE NOT USED INDEX. Then setting tab-index to 1000 shall put the element at the end of tab queue.
 
Because elements with tab-index="-1" (I use this, please don't remove behaviour for click!) are focusable ALSO BY MOUSE or TOUCH, there shall be additional value "none" as true default value (not focusable by click and not focusable by tab key.
 
the "-1" is not true default now. elements without tabindex are not focusable by mouse. ALL BROWSERS treat elements with tabindex="-1" as focusable by mouse. Only IE have here small problem with <span> element inside element with tabindex="-1".
