Fn key -

° I have an old Dell E4310 Latitude portable I've installed Fedora 32 on. it works but I would like to run it with an external keyboard, monitor,and track ball. Those things mostly workexcept that it wants to run the external monitor at the display settings for the little 14" screen. In order to fix that problem I want to be able to operate a toggle display function that uses "Fn + F8" and there is no Fn key on the standard keyboard. Xev shows nothing for the Fn key on the portable. I thought I would just remap the external keyboard  but I have no idea what to do to change that. I found a suggestion googling to use the key to the right of delete, that does not work. Does anyone know how to produce "Fn" from a standard desktop keyboard? -- "...................
