90% of people can't search a web page

[According to a search anthropolist at Google] 90 percent of people in their studies don't know how to use CTRL/Command + F to find a word in a document or web page!..

"90 percent of the US Internet population does not know that. This is on a sample size of thousands," Russell said. "I do these field studies and I can't tell you how many hours I've sat in somebody's house as they've read through a long document trying to find the result they're looking for. At the end I'll say to them, 'Let me show one little trick here,' and very often people will say, 'I can't believe I've been wasting my life!'"
