Default combination like ctrl+shift+v or altgr+shift+a do not work (possibly because of disabling leftmeta?)

I have no idea whether this is enabled by some option, because I do not even know for what to search in docs.

Description: I have broken keyboard so I had to disable leftmeta (leftmeta = noop). After that, it seems some key combinations stopped to work.

Ctrl+shift+v is a "paste" combination in XFCE4 terminal. it does not work with keyd. It does not even see v is pressed in keyd monitor.

Rightalt+shift+a should produce big letter aogonek, righalt+shift+z should produce Ż etc. Quite important to have this if you write in Polish. It does not work. Righalt+z produces ż, shift-z produces Z, righalt+shift+z produces nothing.

I would appreciate pointing to what to do AND explaining why it does not work.

Huh, it works after the reboot. Strange. EDIT: to clarify it didn't work after systemctl restart keyd - so it wasn't the case "you forgot to restart the service"
