On Firefox, I rely on "find as you type", with "'" if looking for a link (for example, type "'repl" to jump to the next "reply" link, and press enter to follow it), and nothing or "/" if looking for plain text in the page; or just tab to move between links (shift+tab if moving backwards).
That's all I need.
Comment on Re: Better keyboard-driven navigation, any?
Those are exactly the tools I use too, and perhaps I must have sound more melodramatic than I actually am, for I can actually survive with the current means but I was under the impression that something better could be done and indeed I'm now trying shmem's new trickeries: experimental evidence is that however alpha can they be considered, they already provide a much enhanced experience at keyboard driven navigation, and precisely of the kind I cherished - if they can be put to completion, then I'm sure that at least as I am concerned, for one, they will result in a more efficient way to achieve the same tasks. I'm going to sleep now, but I'll post tomorrow a review in my scratchpad with the first impressions of use.
