Setting mouse buttons as triggering keys won't take effect

[Noppe1020]

The Z key and X key works fine. When I try setting mouse keys as triggering key by modifying appsetting.yaml referring to Keys Enum, it doesn't work.

# Triggering keys. See https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.keys?view=windowsdesktop-6.0 for more inforamtion.
Keys:
- LButton
- RButton
