checking the tab order in a webpage

[Vishwas]

HI,

I'm a black box tester and have been asked to do high level unit testing on a browser window. Fortunately, using webdriver (via eclipse), i was able to get the solution for this instead of doing it manually.
But the only thing i'm unable to do thru webdriver is to get the tab order of the fields (textboxes) in the web page. When the page loads, the cursor will be at first field (top left corner). From here I want the tab order of the rest of the fields.
Any help on this will be really helpful since i need to test lot many pages in the application.

This look tricky and not sure if worth doing using Selenium.
