Is there a JAWS key stroke to toggle the script on or off?

[Peter Tesar]

Hello,

I'm testing the Thunderbird Blind script. I also have upgraded 
Thunderbird from version 17 to v38, a big jump.

Some strange things are happening. Tasks don't seem to work as I would 
expect.

The script is installed and it is on the 30 day trial. I would like to 
compare how JAWS handles specific tasks with Thunderbird 38, and without 
the script in effect.

I've looked through the web site that describes the many JAWS key 
strokes, and there is nothing about toggling the script on or off. Is 
there such a JAWS key stroke?

Thanks,

Peter T.
