tabindex="-1" doesn't just remove items from the tab order. It also makes items focusable via mouse click or script, which is important when designing custom container widgets like spreadsheets, etc. via Javascript. In fact any negative value does it. Don't try to overload the tabindex attribute. First, the browsers currently optimize it knowing that it's an integer. Second, the scoping is orthogonal. Third, magic values are less readable. It's voodoo. - Aaron Simon Pieters wrote: > Hi, > > Currently if you want to use the tabindex to change the tab order you > mostly have to specify tabindex on all links and form controls prior > to the area you want to modify the tab order, because otherwise that > area would be before all prior elements in the tab order, which in > most cases isn't wanted.
