A practical application for fixed headers is retaining access to search fields on pages with infinite scrolling (which is why they're doing it here). Otherwise, you might be ten pages deep and then have to scroll all the back up to search again. With this, search is accessible at all times.

The ‘search field’ is called an address bar combined with predefined search engines in my browser and accessible at all times using C-x f d without fiddling around with site-defined search entry fields. Oh, and it’s much smaller and takes up space anyhow…

It's entirely possible for someone to use multiple search engines that aren't already predefined. Step outside of your power-user mindset for a second and realize there are "normal" people in this world, unlike you and I, who don't know VIM keybindings or what predefined search engines are and just want to play around with a new search engine.

What about people who use Windows 8 where the address bar disappears? Or mobile devices?

That's why God gave us a "Home" key.

Though Steve, who thought he was God, took it away from some of You.

fn+left arrow is home on a Mac keyboard.

Do you have any idea of how many times I've rediscovered that?

And how long it's taken each time?

That and page-up / page-down. Yes, they're somewhat useful for navigating documents (including webpages).

Regarding page scrolling, I'm usually good with Space and shift-Space.

PgUp/PgDown is useful in some instances, though I'm in OSX rarely enough that I forget what exactly they are when I'm not there.

Terror and repressed memories are like that, you know.

Or ctrl + a in some cases (unixy thing, works in linux terminals as well)

Cmd-Up will also generally bring you to the top of a page.

Things like this are why, on computers with full keyboards, the 'home' key scrolls to the top of the page.
