With JAWS 11 the tabs are not read to you but you can use ctrl+tab to jump
within each tabs properties. The tabs are in this order. Input, Splitting,
Proxy, Output. Another way is to use route JAWS to PC cursor and locate the
4 tabs with your arrow keys and do a JAWS left mouse click and the tab sheet
page properties you chose will appear for you. Press PC cursor mode to get
back in normal mode which is NumPad +.
