Hello Peter,
I was able to jog using the on-screen buttons with my touch screen Windows 10 computer. It was a bit tricky at first, but I could jog in continuous mode using a double-click-and-hold method. It may be a bit different on your computer, but try that out. You should also be able to jog in incremental mode one click at a time, but I know that isn't always what you need to get into the right position.
