How to find data for one tab in chrome

[JAFN]

Hello yet again,

I have finished my initial script as I can think of nothing useful to add to it.

So I'm on to my next learning experience. And I don't know where to begin researching it.

What I want to do is create a simply two button always on top window that swaps the two edit fields in Google translate running in chrome.

I want to figure most of this out on my own but need a starting point.

I suspect this is an ambitious script for a relative newbie but scripts I actually need is how I learn.

So:

1. how do I determine that I am in the tab I want.

2. how do I access one of the edit boxes.

Thanks

I figured out the first one.
