UI doesn't allow setting Left Ctrl as Compose
In Ubuntu 20.04 (before !785 (merged)), I was able to set Left Ctrl as my Compose key using gnome-tweaks. I just upgraded to 22.04, where the Compose key settings have been removed from gnome-tweaks and moved into control-center, but Left Ctrl is not in the list of options for Compose.
I was able to restore Left Ctrl as my Compose key using:
$ gsettings set org.gnome.desktop.input-sources xkb-options ...
adding 'compose:lctrl' to that list, but it would be nice to expose it in the GUI.
For context, my modifier settings are:
- Caps Lock is Ctrl ('ctrl:nocaps')
- Left Ctrl is Compose ('compose:lctrl')
- Both Shift keys enable/disable Caps Lock ('shift:both_capslock')
which gives me both a Ctrl key on both sides of the keyboard and an easily-accessible Compose key.
Originally reported to Ubuntu as https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1973226. I've set this as a bug because it caused a regression for me — my modifier settings were lost after upgrade. I could understand reclassifying it as a feature request if that's desired.
