Thank you for your prompt reply. Since I used Raildriver exclusively in previous versions I never become accustomed to arcane keyboard command use. What confuses me is that if the keyboard commands from previous versions work, what is the difficulty in accomodating Raildriver and, if you are correct, why are there years needed? I understand priorities and certainly am not privy to the list of "bigger operaerating things to fix" but certainly improving the UI should be one, if not paramount. This is, of course only my opinion.
I hope that others will be able to assist me with using older content. Again, thank you for your assistance.
