"I don't want that key to be customizable"
Wayland is a lose.
sudo raspi-config Advanced Options menu, select the Wayland option – disable it, and reboot.
Must not be using wayland. Can't find any way to do half this stuff on wayland anyway. Switched back to X11.
$ sudo apt install gnome-tweak-tool
then use it to map caps lock to ctrl, and swap left-ctrl and right ctrl to hyper
would rather have meta in center left and 2nd from right would rather super and hyper work
The normal xterm mouse functionality for such clicks is still available by holding down the SHIFT key when you press the mouse button
"xkb configuration is black magic in general and sheer luck in Ubuntu."
