Sorry for the delay. Here is the installer <https://github.com/campg2j003/JAWS-Script-for-Audacity/releases/download/rel2.2.2-beta-2018-10-25/Jaws-Script-for-Audacity_2_2_2-beta-2018-10-25.exe> for a beta release of the scripts that has been converted to work with Audacity 2.3.0. Changing the control IDs and some of the strings that identify window titles and classes is all that has been done. I notice that Silence Preview often doesn't get turned off. Switch away from Audacity and back to reset it. I haven't implemented a script for the Punch and Roll key. Should I? The README and messages aren't updated. The link to the user guide hasn't been updated, but you can do that. This should let you use the selection stuff, which is the main thing that was broken.
Let me know of anything else I missed.
