I tried your code out. It works OK, but its limited to emitting events to a GTK managed window and what I really wanted was to insert events into the X11/Wayland Display server, so that any application which has the focus could receive the events.

Maybe that is not possible within GTK and I need to access lower-level libraries like X/Wayland?

I didn't know about xmodmap. I don't want to capture the standard out, tho. But I'll look into their source code to say what they code to capture the mapping.

Thank you for your help, Allin! That gave me some direction.
