Comment 9 for bug 1875056

AFAICT, my left CTRL key is working but I won't be able to enable this feature.
Actually looking at Thomas's screenshot I've noticed that the dconf setting apparently has been moved from settings-daemon/mouse to desktop/interface, what explains that I wouldn't found the key definition in the schemas.xml file even in the deprecated-keys section.
But setting the key true in the new config won't enable either.
I can also notice that toggling the key value in dconf won't change the the value in the "official" Settings/mouseand keyboard section or even in the Tweak app. And BTW the new dconf description reads that the pointer location will be be triggered by pressing *any* key (?) - as can be seen in Thomas's screenshot.
Seems like the gnome shell is still expecting for the old key activation. I've tried to add the "locate pointer" in the schemas.xml's settings-daemon/interface but it won't show up aon dconf and won't activate anything either (even after reboot). Would there be a way to redirect the key from desktop/interface to settings-daemon/mouse so that the shell could grab it ? I'm on 21.04.
