Logitech MX Keys Mini - wrong mapping of forward delete key

Describe the bug
Forward delete key is remapped to a Chinese (?) ideogram (see snapshot) when MX Keys Mini is configured as a Logitech Keyboard.


Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.): Logitech MX Keys Mini


Screenshots


Device information:

  • Type of Mac: MacbookPro M1 Pro
  • macOS version: Sonoma 14.8.1
  • BetterTouchTool version: 6.111,2026012703

could you copy & paste that shortcut config here? The chinese character means BTT doesn't know the key. (Copy the whole trigger, then paste the JSON here, then I can check the ID of that key and add it to the blacklist for this keyboard)

By default BTT makes all keys the keyboard reports as "divertable" available for remapping in BTT. However you can also specify only the keys you actually want to change:

Hi, thank you for this very quick replay. Here is the shortcut (didn't know it could be exported as json, nice trick):

[

        "BTTOrder" : 30,
        "BTTAutoAdaptToKeyboardLayout" : 0
      }
    ]
  }
]

While you change the default behavior I will check the remapping option. Thank you once again!

I have added the key to the general ignore-list, it should now work correctly in 6.118
