Ah, bummer! I was immediately thinking about a small popup on full screen mode showing the different available methods for a command with the current one highlighted but this is probably taking it too far ;) So no hiding the UI. Still this will be a great help as I'm slowly running out of left hand shortcut keys. And with this only the eyes will have to travel to the right, not the mouse :)

Best,
Sven

Edi: hmm, come to think of it that also doesn't work, right? The UI is not reflecting the current state of a command when invoked via shortkey
