There's no way in GUI to set the windows key (Super) as a trigger

[Marcin Kaczorek]

I used unity for a bit and got used to pressing only the windows key. It's possible in kupfer but only for the [kupfer] section of the config file. No way to do that from gui.

Since binding the Super key alone to Kupfer in practice blocks all other uses of Super, it is regarded as much more unhelpful than helpful to allow binding single modifiers.

Sure, it has a Quicksilver precedent and it is tracked in a preexisting bug report—but kupfer doesn't have a keybinder library smart enough to allow us to use the Super modifier or any other in a smart way without blocking it completely.

FWIW at least under XFCE it's possible to bind Super L with the global keybinder to `dbus-send --dest=se.kaizer.kupfer --type=method_call /interface se.kaizer.kupfer.Listener.ShowHide`
