If you are asking me to create a custom keyboard for you, the answer is no.
That's for the reasons I mentioned in post #12. Though not difficult, its tedious to do due to lots of repetitive coding and is likely to take some time.
Attached is a quick DEMO which will allow you to try each of the built in on-screen keyboards with Access. I am aware that the DEMO isn't perfect but it should enable you to decide whether either of these items suits your needs.
NOTE: If you use the tablet version, use the 'button' in the top left corner to try its different variations. The tablet keyboard may have to be closed manually in this DEMO
Returning to your registry issue, the code I gave you in the other thread should have included all you needed. See
