Another tweak: If there's a very unique string close to the thing you want to click, you can press / to open "Quick find" (for all text). Search for the string, then use Tab and Shift-Tab to jump to your thing.
Back in the old days, I used the Vimperator and Pentadactyl extensions for even more keyboard awesomeness, don't know what's the current state of the art there?
But the ' key is… just always there! I wanna practice using it a lot!
@blinry / works similarly to ctrl-f, but if there are multiple occurences then ctrl-f lets you choose which one you want to go to, which is why I generally prefer it
