On your Logitech MX Keys for Mac, the Globe (Global) key function is assigned by default to the fn key(located on the bottom row or near the navigation block). On macOS, tapping this key triggers system-level language switching. If you accidentally bump it while typing in chat boxes, it instantly swaps your input language to French. 


You can fully disable this behavior directly within the macOS System Settings.


How to Disable the Globe Key Language Switching

  1. Open the System Settings app on your Mac.
  2. Scroll down the left sidebar and click on Keyboard.
  3. Look for the setting labeled "Press 🌐 key to" (or "Press fn key to").
  4. Change the dropdown selection from Change Input Source to Do Nothing.



More info from Apple: Use keyboard function keys on Mac - Apple Support


Once disabled, pressing the fn key on your MX Keys will no longer switch your layout to French, resolving your chat issue entirely.
