Onyx PC Spacebar

According to the documentation, the is supposed to act as a go button for whatever Q list of selected or for the main to list. I’m running onyx on a laptop, and that does not seem to work. When I bring up the virtual keyboard on the screen, that doesn’t work either.
Is there any way to assign the goal function to a real key on a laptop keyboard like the or the enter or tab or anything?

scroll lock!?
