Comment 1 for bug 1449

As best I can tell, this is pretty difficult to fix if we want to autofocus the first widget on the form. :/

The problem is that, though I can manually set the tabindex of each input widget to make the tab ordering Just Work (whilst also autofocussing the title widget when the page is loaded), there appears to be no way to set the tabindex of the "Add" button in ZCML.

I believe that I need to configure it in ZCML, because all the bug add forms share bug-add.pt, but they don't necessarily all want the same tabindex for the "Add" button.
