Ctrl+F (find) on Safari?

I just recently switched from a PC to a macbook pro, and there's just one thing that's bugging me. Does safari have anything similar to ctrl+F? Internet Explorer had this thing where you held control, hit F, and then a window with a text box popped up. You typed a search query into it and then it found all instances on the page, then you could scroll through the other instances of the query on the page. It was really useful, and now researching/looking for things is kind of annoying without it.

Also, I know firefox doesn't have a place on the apple discussion forums, but I have the same problem with the second new browser I've started using, so it would save me another post on another forum if anybody knew how to solve this problem on Firefox 3 as well.
