Ctrl+Super+Return

? Hyprland has a matching binding; its runtime effect is unknown.
  Whykey temporarily intercepted the compositor event to inspect its
  configuration. That does not prove the configured action ran.
  Whykey cannot determine whether the Lua/plugin action passes the key onward.
  Observed via Hyprland (suppressed).

Route
  1  Remapper      v  none detected
  2  Hyprland      x  Herdr                                             observed
  3  Terminal      -  not reached
  4  TTY driver    -  not reached
  5  Input method  -  not reached
  6  Multiplexer   -  not reached
  7  Shell         -  not reached

Bound in
  __lua 285 (Lua dispatcher; whykey does not execute it)

Confidence  observed: whykey saw the key at Hyprland. Layers after that point
            are predicted from configuration.

To confirm
  whykey listen --suppress  inspect a binding without letting its action run

More  whykey listen -v
