Kim,

Settings Center
Ctrl+Shift+d for the default config type Key Label in the search field
Enter on that
Press the button.
In the list, you can toggle the speak/mute state of many keys with Alt+T as
you arrow through the list.
Press OK to save your settings, and of course save the config.

Note that these setting *do not* get merged over when you update to a new
JAWS version. Also they are clobbered even if you just install a minor
update. Frustrating, as it takes time to go through the whole darn list
every darn time there's an upgrade, since it's buried in the default
configuration file.

I've already posted this to
FS as something they should have fixed years ago.
