How to create a global JAWS script?

Damn. What if somebody has other extensions? OK, I will search

plus, their scripting language is nothing short of awffle, so I won't recommend anyone but experts do it, it's hard as hell, kinda buggy, and unrewarding. But yeah, make a python or batch script or something that replaces an include line in default.jss that points to your script. Then, you can invoke it whenever jaws updates. This way, your script would get included in default.jss everytime, despite the updates.

yeah.  But fair warning.  The word simple and the word Jaws scripting don't ever belong in the same sentence.  To do some of what DictationBridge needed we had to write a thing in C++ that talked to Jaws instead of Jaws scripts.  It's very limited.  Simple NVDA add-ons count as very complicated in Jaws scripting land.

I don't know all of the details.  I only wrote an initial version before I was no longer involved in the project due to the rest of my life going in a traditional job direction and such like that.  It's a good source of info though, in that it does basically everything you could ever want to do with jaws scripting one way or another.  You will probably want to copy that installer, among other things.

Jaws scripts are very good at responding to jaws-specific keys that you assign.  They're very bad at responding to anything else without a lot of hacky work.
