Thought I'd add this to things that have already been mentioned:
In safari and shiira, if you go to a new link and/or window and then
close that window or use the "back" button, often you actually are
where you left off on that page. But as soon as you use vokeys you
will find yourself back at the top of the page. when you come back to
a former page, sometimes you'll hear the link from which you left
voiced, but even if you don't hear this, it often works to use tab or
option tab to navigate when you initially return to the page instead
of vo keys. Very often you are then able to continue where you left
off, and once you have tabbed or option-tabbed past one link you can
resume vokey-arrow navigation without losing your place if you want
to do so.
