Karabiner Elements .json file to enable YubiKey output only with a modifier key (caps lock) pressed. This prevents you chatting to people fjsdjhkjahsdkjahslkjsdhgskjdvnskdbvsjkdb.

Prevents accidental Yubikey input when you're holding a modifier key (e.g. CMD, which would otherwise trigger a lot of shortcuts leads to awestruck)

1. Install Karabiner Elements

2. Enable modifying YubiKey output in preferences

3. Make sure your VID/PID for the Yubikey (above) match those in the JSON file.

4. Copy the yubi.json file to your ~/.config/karabiner/assets/complex_modifications

5. Add the modifications under "complex modifications" in preferences

6. Make sure both are enabled

7. Profit!

• Caps Lock + yubikey = sliqmnoianwiiwmdoqnsknfoisjjd
• Yubikey alone = ignored

1. Does this kill my caps lock?

• Yes.

2. It doesn't work.

• Fix VID/PID in the JSON file.
• Add checkbox to modify output from yubikey in Karabiner
• Check if Karabiner works in the first place
