I wasn't even aware / was for quick search. I always used Ctrl+F, which is incidentally much easier on my localized keyboard. But trying it right now, I notice that / and Ctrl+F opens different dialogs? One is called "Quick Find", the other "Find in Page", with the latter offering additional options, even though both seem to do the same thing? What is up with that?
