Hi Keith,
When you connect your phone and go to the device button, you have a treeview
now with the items which before were radio buttons, e.g. Summary, Apps, Music
and so on. You just arrow to the item/category you want in the treeview and
then tab until you get to all your selections.
Tab until you get to devices, press the device you want such as iPhone, you
should tab and see a treeview, but it should land on summary, Go through those
options and eventually you will find backup, this is just like it was as it was
when we had the sidebar, same options such as music, … then
