Visit Special:Interwiki/add on a wiki where you have rights to edit the interwiki data.
As you press [Tab] the input focus cycles through,
- "Prefix" field
- URL, skipping Forward and Transclude checkboxes - BUG
- Reason
- Search box, skipping [Add] button - BUG
- Navigation link and Search link
- Forward checkbox
- Transclude checkbox
- [Add] button.
Expected result:
Page loads with "Prefix" focused, and tabbing takes you through all the form fields, including the checkboxes and [Add], in order, before going to skin fields.
I think the fix is to simply remove ' tabindex' => 1 from the text input fields in in Interwiki_body.php, then I get the expected tabbing behavior. Add add autocus to the first input field.
