Thanks, good suggestion -- I usually try to avoid extensions as much as possible for many reasons (incl. that Apple actually discourages it), but I'll look into it.

Where does Apple discourages using your own keyboard layout (not KE)?

Though I personally would be easily discouraged if they made good native keybinding support

I wrote extension, not layout. I succeed finally with Ukelele thanks.
