Hugh Pickens writes: Google search anthropologist Dan Russell says that 90 percent of people in his studies don't know how to use CTRL/Command + F to find a word in a document or web page.

'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' - says Russell, who has studied thousands of people on how they search for stuff. '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!"

'Just like we learn to skim tables of content or look through an index or just skim chapter titles to find what we're looking for, we need to teach people about this CTRL+F thing' - says Alexis Madrigal. 'I probably use that trick 20 times per day and yet the vast majority of people don't use it at all' - writes Madrigal.

'We're talking about the future of almost all knowledge acquisition and yet schools don't spend nearly as much time on this skill as they do on other equally important areas.'
