Hi! Have you tried replacing ctrl with control or cmd?
there is no way to track the control key with the when key pressed block, but you can track it through javascript (I don't know that much javascript so I can't tell you the javascript to track the control key)
"ctrl control" is keyName for [Ctrl], but it works only once ;( and then is reported as pressed forever ...
uh, if you press both ctrl keys at once after pressing one, then let go of a key, it'll say that the key is not pressed.
