OK Simon
what i did was
VO plus arrows around the page
when i found a heading i interacted with it
then i pressed the command key plus the enter key,i.e. the command key
on the right and followed by the enter key next to it. i
believe that will rout the mouse to the link.
now all i do from that point is press the option key and the mouse
button.
this should start your download
note that VO will not call them links as such but heading
i also did the same as above on another site i.e. blindkiss.com but
to download its links i had to press ctrl plus mouse button instead.
i guess it's how the site is designed.
hope this might be of some use to you.
