How to search/replace using imacro.

Hello,

Tried searching google for the answer but because I lack programming knowledge, couldn't understand how to use EVAL or javascript stuff.

So, basically, let's say I have 10 tabs open.I'm trying to find a way so the imacro can go to each tab and replace the text.Can anyone please give me the imacro code to use.

Thanks

what exactly you are replacing? where do you want to replace text?
