These two videos show how Find In Page for iPhone Safari can be used to quickly find text in long Web pages.
In this first video, I am reading a blog post that has very many comments, and I would like to know if a software library I am interested in (named "Sequel") is mentioned anywhere in the blog post or in the comments that follow. Without Find In Page, I would have to read the entire page, looking for the word "Sequel". Find In Page makes this tedious task a snap.
In this second video, I am looking at the official HTTP specification document - a VERY long page indeed (think book-sized!). In this case, reading the entire page in search of a single word or phrase is downright impossible. But not with Find In Page! I look up every occurrence of the text "200 OK" in this document in mere moments.
