F5 is enough of a meme that I know it despite being a mac user; what does F9 do in this context?

hmm, I don't know either. F3 .. F7 and F10 are listed in [1], but not F8 and F9, from a quick skim.

Toggling reader mode is Ctrl + Alt + R apparently.

Edit: works for me.

Must toggle reader mode

F9 toggles reader mode. Frequently the paywalled content disappears as soon as you hit F9, but will reappear if you hit F5 while reader mode is in effect.
