I have a busted close-bracket key on my keyboard. Previously, I had used Karabiner to map L-control+open_bracket to close_bracket using a custom rule I wrote in the xml-format used by karabiner.

However, now that I've updated to Sierra, Karabiner is out, and Karabiner elements is in. Karabiner elements uses a JSON format. I tried to create a new rule and stick it in the JSON file:

"rules": [{"manipulators": [{"description": "bracket rule","from": {"key_code": "open_bracket", "modifiers": ["left_control"] }, "to": [{"key_code": "close_bracket","modifiers":[] }] }]}]

However, this rule doesn't seem to work the way I'd like it to (it just maps open_bracket to close_bracket).

Does anyone have an insight into what I'm doing wrong here?

THANKS!
