Yes, I just wasn't sure whether that should show up by default or not--
wouldn't it be a bit distracting to have it show up on every web page
you visited whether you intended to interact with that page or not? 
Maybe not, I guess, it's probably more beneficial to show it than to not
show it.

Yes, that's what I meant.  Just the usual behaviour, in other words.

Well, I thought about that, but once a block of text has focus, the
arrow keys would move the cursor around within that block-- the way it
was described in this proposal, anyway.  Or are you suggesting that all
the text on the page should be considered as one block?  That's probably
a better idea, come to think of it.

Hmm, last time I tried either of those browsers I couldn't select text
from the keyboard alone-- I'll have to try again, it obviously wasn't
very intuitive!

Yes, sounds like a good idea.

Certainly makes sense for links... I suppose it does for interactive
elements too, if you were copying from a web page into a webpage editor,
for example.  And it would make the "consider all static text on the
page to be part of the same block" idea work better.

Well, as I said, last time I looked at it I couldn't get any keyboard
navigation to work at all, other than for the interactive elements on
the page-- maybe I just wasn't trying hard enough!  I'll take another

Good point.
