I also gotta thank you a LOT for the option to use
"ctrl+enter": "unset"
to prevent accidental message sending. To anyone coming after me: Be sure to put that command into the "Compose key bindings" window, not the "Main key bindings" one where the rest of the initial bindings is.

edit: Unfortunately whenever I start Thunderbird the unsetting of Ctrl-Enter is inactive until I switch the addon off and on again. Sadly this means that the addon is useless to me right now.

edit2: For some reason the error has disappeared again for now. I have no idea what's different, but I can use the add-on again.

이 검토는 현재 부가 기능의 이전 (2.1.3) 버전에 대한 것입니다. 

Sorry that the add-on could not do what you wanted. You can open an issue at https://github.com/wshanks/tbkeys/issues if you like. I tried to reproduce your issue but could not. "ctrl+enter" remained unset for me after restarting Thunderbird.
