@Heliograph Happy to try to answer any questions! Do you mean how screen readers behave to each other? Or how they make the computer behave compared to not having one running?
For how they work at all, we have a quick video demo of NVDA here: https://www.youtube.com/watch?v=tCFyyqy9mqo
There are settings you can change which alter (or restore) behaviour - happy to go through any of those you might be interested in.
For differences between screen readers, here's a page on Jaws & NVDA: https://github.com/nvaccess/nvda/wiki/SwitchingFromJawsToNVDA
@vol4life8657 Sure - and I wasn't saying the others didn't, though yes, I put more of a case for NVDA (it is kind of my job) - re the price of Jaws - the account I was replying to is on an Australian server. In Australian dollars, Jaws Home is $2,280 according to Qantum: https://www.quantumrlv.com.au/products/jaws-home-edition-with-sma or Vision Australia: https://shop.visionaustralia.org/jaws-home-with-sma.html or Visability: https://livingaids.com.au/products/jaws-home
An SMA on its own from most of those looks to be about $310 AUD
