I'm trying to find and put on my toolbar the icon/way to do a word search of a website/document that does not - icon marker

Higlights and then you only need to scroll (I already have a star symbol in yellow), but I need, when you click on the Word toolbar and go down the page for the next occurrence of the word that automatically searches. In general, there is a sound that accompanies the teeth every time the computer is the word .. then the side on the floor and click again to see moved to the next position is on the side track.

I had it up there, but now it's over and it is very difficult to select just one word and you move around (unlike the computer does it for you) when the page is really long.

I have two toolbars from Yahoo and Google.

I need to know where to find and insert this function is invoked, and how to post them on the Internet. A link can be helpful if possible.

Thank you .. it helps me a lot!
