word prediction in High Sierra

I have been using KeyStokes by Assistiveware since I was a beta tester. I use just the word prediction feature, and not the onscreen keyboard. I have a keyboard fitted with a keyguard.

As High Sierra now has these features, Keystrokes users have been told that Keystrokes will not work in High Sierra, but as with Read&Write Gold, the predicted words will have to be clicked on, rather than selected with one of the keyboard's two sets of numbers.

Obviously, I am worried as if I never upgrade, I shall eventually hit software issues.

Has anybody used this new word prediction? I would be really interested to hear what it is like.

Thanks..

Sarah
