This would somewhat fall in line with, for example, the copilot key being implemented as shift+super+f23. I agree that that seems to be the intent. > Following this, my suggestion is to do this remapping and handle the rest in xkeyboard-config xkeyboard config already contains mappings for F13 - F18 and F20-F23 in /usr/share/X11/xkb/symbols/inet So all that needs to happen there is map FK19 -> F19 and FK24 -> F24. And then teach KDE + GNOME that ctrl+super+f24 means touchpad-toggle. We could maybe get away with also dropping the weird mappings for FK13 - FK18 and map those straight to F13 - F18, but we need the special mappings for F20 - F23 to stay in place to not break stuff.
