How do I specify the Super key in dual-function-keys?

by Rubin|Published October 23, 2023

I try to use dual-function-keys (part of interception tools) in order to use capslock as escape AND Super key.

My yaml file looks like this:

TIMING:
  TAP_MILLISEC: 150
MAPINGS:
  - KEY: KEY_CAPSLOCK
    TAP: KEY_ESC
    HOLD: KEY_SUPER

The tap functionality works fine, but holding capslock does not. I suspect the name of the super key is different, but don’t know the correct name.
