It should be 8 or more.  But it has nothing to do with the magic number 7 +-
2.  (or the biblical 7).

It is based on the number of steps (over links) and when it is more work to
use a jump link than to just tab over the links etc. 

This is also still very much an open issue - but is an attempt to address
this issue in a testable fashion.

In guideline 2.4, the second lvl 2 success criterion says:
Large blocks of material that are repeated on multiple pages, such as
navigation menus with MORE THAN 8 OR MORE links, can be bypassed by people
who use screen readers or who navigate via keyboard or keyboard interface.

More than 8 or more should be either "more than 8" or "8 or more" links.
There is a difference: "more than 8" excludes 8, "8 or more" includes 8. I
think we want to include 8, so it should either be "more than 7" or "8 or
more". I prefer "8 or more" since we do not require anything for 7 but do
for 8 links. Also, 7 seems to be the 'magic number' of items that people can
manage without further hierarchy so it would make sense to require further
navigation aids for 8 links or more.
