Copy word from Active page

[ibdv4521]

Ok guys, you all have been very helpful with my weird questions lol. Here is another one. If I want to be able to search the current webpage I'm looking at for a certain string of words and copy it. What is the best method. I am familiar with writing to files...but how to search a page for example.. anything that follows "ASIN:" to copy that string. From there I can code it, but I don't know how to interact with open windows :(
