It is taking a while to get used to the enter key. So this sdcard stops me hitting enter by mistake. I don’t seem to have the same issue with tab key.
I find I have to keep looking at the thumb cluster. Also feeling stress in my left hand, perhaps due to more stretching as I use my fingers more evenly.
Once my speed is up I will try some plugins.
All in all, a great keyboard. It’s only been a day and my speed is back to useable.
