Comment 4 for bug 20204

I tried this too. xev does the following output when pressing those keys:

KeyPress event, serial 25, synthetic NO, window 0x4400001,
    root 0x48, subw 0x0, time 11202776, (-31,459), root:(716,573),
    state 0x0, keycode 234 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes:

KeyRelease event, serial 25, synthetic NO, window 0x4400001,
    root 0x48, subw 0x0, time 11202856, (-31,459), root:(716,573),
    state 0x0, keycode 234 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes:

I had found somewhere in the web some patches to the XKB Config adding Symbols
to those keys. Not sure if they are applicable at all to breezy's xorg
