We have found that there are some surprisingly basic search techniques that people just don’t know about. I interviewed a bus driver who was searching for a transportation rule for a test. She was scrolling line-by-line through a 100-page web document, so I asked her why she didn’t use “control F” to search by keyword. It turns out she didn’t know about this absolutely basic browser function. Amazed by this, we ran a survey that found 90 per cent of people don’t know about it.
