That doesn't really mesh with the quote, which was, "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."
hum, there is a menu option for find in all browsers I know of. Sure, under chrome it's in the wrench menu but if it's a menu it might as well be lost for a large group of users.
Chrome's Find menu has "Search the Web", "Find", "Find Next", "Find Previous", "Use Selection for Find" and "Jump to Selection". I'm willing to bet non-techies would be utterly confused by all those possibilities.
This is a valid point. I'm in Germany and half of my software is localized, so search is Strg-S, the other half is not, so search is Ctrl-F or F3, or /, or whatever.
I think most people know Edit->Find
Do 90% of people not know what a keyboard shortcut is? Yeah, I believe that.
