by default, to navigate links, you use option-tab.
You can also use control-option with arrows to find the "html content" and
then control-option-shift-down arrow to "interact" with the "html content"
and then use control-option-arrows to move around and when you find
something you want to activate like a link, button or checkbox, you can use
control-option-space bar to activate it. You can also use control-option-u
to render a list of links and type a unique string to move to where you want
to go links wise. Using control-option-i brings up a list of all the
"items" on a page or in a window and this is traversed in the same way as
the links list. There is much info on this in the VoiceOver getting started
manual which I can never seem to remember a link to but which is found in
the archives of this list and also in the archives of
