Hello,

At the moment I don't know, how to include the buttons into the taborder, because the buttons are optional. Without JavaScript, the buttons does not exist. With disabled BB-code-features all or specific buttons does not exist.

In posting.js#L538, the tabIndex attribute is defined (always -1). Most of the attributes of a button are defined by the variable obj such as obj.code. I think it is quite easy add a further attribute to obj, e.g. in posting.js#L433 and posting.js#L484. We just have to figure out a reliable starting value.
