Not all of the login options are addressable via option-tab in OSX, at least. Can this be addressed?
I'm just a keyboard-centric coder, but I do feel strongly that my ability to highlight and select action items (inputs, links, buttons, and other elements that trigger actions) via the tab / option-tab standard is an important indicator of the level of both the power-usability and the universal accessibility of the interface.
Any chance of making this happen site-wide? My example, as well ast the impetus for this question, relates to the lack of support for (option/alt)-tabbing to the "log in with:" actions on the login page of StackOverflow.
