Well, then that idea is out the window. As I just said to Neil, I think the next step would be to find out what the default contents HELPINFO are. IOW, when F1 is pressed Windows sends a non-application specific WM_HELP message and structure to the window. Fox understands this and reacts accordingly. In conjunction with setting the topic via an ON KEY LABEL F1 HELP < topic > command, this might do it.
