What I am suggesting is to have a set of global keyboard commands - ones
that
apply to all widgets. We used this concept for ARIA properties.

I am also looking at this like the inheritance model we have in ARIA. I
would like
accordion to be thought of as a subclass of tabpanel. Consequently, as many
of the
keyboard commands used in tabpanel should be used in accordion.

So, looking at inheritance, why couldn't a notebook tab have a menu button?

Note: I tried ctrl up/down in the example you gave and it did not work.

I am not sure what the difference is between the two other than ctrl+F10
brings you
to the browser menu on Windows. I think context menu launching should be
system wide.

Earl, you misunderstood the question. Why does tabpanel (not the accordion)
not support enter/space?
It is inconsistent with accordion which does.

I don't know. Again, I want to emphasize the inheritance model. If an
accordion were a multiselectable tabpanel and a tabpanel allowed the user
to delete
a panel, why shouldn't the accordion? What is so special about the
accordion that
you would not allow this?

Did you mean collapse all, expand all, an refresh? How do you get to these
with
the keyboard?

Please come to the Monday PF call.
