Maybe ... but my point was that even when searching for an arbitrary word on the screen, I notice that I'm significantly faster than a non-savvy user. E.g. if I'm on a call with a support desk and they're walking me through some steps on their website, I find I can easily 'take in' the entire screen and focus on that one word they want me to click on. Of course, I know a website is a bad example here, given that I could've just pressed Ctrl-F, but the idea holds for other complex non-searchable UIs too.
