Tabindex Bookmarklet for Accessibility Testing

Tabindex bookmarklet helps users to identify the use of tabindex attribute on the page. This bookmarklet can recognize the negative tabindexes and positive indexes. During an accessibility audit it is important to know if the page flows in right focus order, when tabindex of 0, 1 or -1 is provided it alters the focus order of the keyboard navigation. Tabindex bookmarklet identifies and presents all the content that is provided with a tabindex values, and developer or accessibility tester can then evaluate if tabindex values are applicable or not.
