Chrome, the web browser application from Google, has a brilliant user interface feature that highlights vertical scroll bar to indicate the location of the words we searched for. The following screen grab is captured when I searched for word Microsoft using the built in Find option of Google Chrome.
Apart from highlighting the word Microsoft in the visible portion of the web page, the vertical scroll bar indicates the occurrences of the word Microsoft in the rest of the web page. You can click on the Yellow colour indicators on the scroll bar to scroll to the line that contains the search term.
